Colored crushed stone business plan. Polymer paints for crushed stone. What equipment is required for the production of colored crushed stone?

Typically, crushed stone is used in the production of reinforced concrete structures or in road construction. Colored crushed stone - decorative material from a small fraction of natural stone. After painting, colored gravel is used to decorate interiors, use them in landscape design, line the bottom of aquariums, etc.

Crushed stone is one of the most commonly used materials in construction. It is usually used as a filler for cement-concrete and asphalt concrete mixtures, in the production of reinforced concrete structures and as one of them during the construction of highways.

In the last couple of decades there have been the new kind specially prepared construction crushed stone, performing a decorative rather than a construction function.

Colored crushed stone: brief description

Colored crushed stone is a specially painted natural stone (granite, marble) of a fine fraction. After painting, the surface of the crushed stone becomes smooth. The dye does not lose its properties from changes in temperature, humidity, sunlight and other influences.

Other names for colored (painted) crushed stone are painted pebbles, colored gravel, decorative painted stone. It is usually sold in bags. Used in landscape design, interior decoration, aquarium decoration, etc.

Let's consider the feasibility of producing colored crushed stone from the point of view of commercial benefits. The cost of one ton of ordinary crushed stone is 2,000 rubles, and the cost of a bag of such crushed stone is 300 rubles, i.e. You can earn decent money only by packaging. The cost of colored crushed stone is much higher, so its production will be profitable.

Production of colored crushed stone

Ordinary granite (marble) crushed stone is painted with special dyes, dried, packaged and sent to trade or to the consumer. A package of painted crushed stone usually holds 20-25 kg.

Manufacturers of such crushed stone unanimously declare that acrylic dye is best suited for painting. However, in the absence of one, several options for using other dyes can be proposed. Let's start with necessary equipment and tools for painting crushed stone.

Equipment, tools and materials

So, to produce colored crushed stone you will need:

• Crushed stone - 2-3 tons;
• Paint – 100 kg;
• Installation or room for drying material with good ventilation;
• Vibrating screen VG-1 or its analogues – 1 unit. (from RUB 89,000);
• Concrete mixer (bunker for painting) – 1 unit. (from 8,000 rub.)

If there are problems with financing, then at first you can do without the noise. In this case, you will have to sift the crushed stone manually using outer-size mesh. You can also not purchase a drying chamber yet, but dry the crushed stone directly in the open air. Thus, the only equipment you need is a concrete mixer.

Already from the set of equipment it is clear that this production is a low-cost business. You can cost no more than 100 thousand rubles to fully equip the production. If this is not possible, it is enough to buy a concrete mixer, sieves for sifting, paint and crushed stone itself.

Crushed stone painting technology

Name and sequence of technological processes:

1.​ Sorting crushed stone to separate debris and separate fractions

Using a screen or mesh, crushed stone is sorted into fractions of the required size. As a rule, crushed stone more than 10 mm is used, since it is more convenient to paint. Sorting is also necessary to remove contaminants from crushed stone.

2.​ Loading individual fractions of crushed stone into the concrete mixer hopper and adding paint

Paint of the required color is added in a volume of 20% of the volume of loaded crushed stone.

3.​ Mixing crushed stone with paint

Mix for 40-60 minutes to completely cover the material with a film.

4.​ unloading crushed stone from a concrete mixer

The crushed stone should be removed through the mesh above the receiving hopper so that excess paint flows into the hopper and is used for the next painting.

5.​ Drying painted crushed stone

For large production volumes, it is advisable to use a drying chamber. If on initial stage There is no such chamber, then you can dry it in the open air.

6.​ Packing of painted crushed stone

Registration of activities

For small production, the best form of business registration will be individual entrepreneur -. The registration procedure is simple and does not require large expenses.

It is better to choose the simplified tax system (simplified taxation system) with a tax of 15% of profit. To register on this system, you must submit an application for a transition from the general taxation system to the simplified tax system within 3 days after registering an individual entrepreneur.

Economics of colored crushed stone production

Material consumption for the production of 1 ton of colored crushed stone:

• Crushed granite (marble). The cost of 1 ton of crushed stone is 2,000 rubles.
• Water-based paint with a consumption of 20 kg per ton of crushed stone. The cost of paint is 200 rubles/kg. To produce 1 ton of crushed stone you need to buy paints for 4,000 rubles.

Total: the cost of producing 1 ton of colored crushed stone is 6,000 rubles.

The retail price of colored crushed stone is 22,500 rubles per ton. The profit per ton will be 16,500 rubles.

Remained unaccounted for wage, taxes, advertising and transport costs, packaging costs, rent, etc. However, from the above figures it is clear that the net profit will be at least 50% of the investment. For a low-cost business this is a very good indicator.

As in any production, the main thing for a successful business is to ensure constant sales of what is produced. Even before production begins, market research should be conducted on the use and need for your products.

Research should be carried out among companies involved in landscape design, interior design, etc. Some of the products can be sold to construction supermarkets, shops, markets, etc. Packing crushed stone in paper or plastic bags of 20-25 kg is convenient for transfer to retail.

In order to create an interesting and colorful design for a garden or park, they often resort to using painted crushed stone. In addition, such original decorative material is widely used in interior design, when decorating aquariums and decorative flower pots.

The demand for painted crushed stone is quite high and has not fallen for many years. Using the production of colored crushed stone as a business is quite profitable. The technology for its production is not particularly difficult, and it is quite easy to master.

Business documents

To start your own business, first of all, you need to register. To engage in painting crushed stone for the purpose of its subsequent sale, you can register as an individual entrepreneur (IP) or legal entity– limited liability companies (LLC).

Since such production is not characterized by huge turnover and large industrial production, it is easier and more convenient to register as an individual entrepreneur. To do this you need:

• write an application in the prescribed form to the federal tax service at your place of registration;
• pay the state fee for registration as an individual entrepreneur;
• present a passport or other document that allows you to identify your identity.

After submitting the specified documents, after five working days, you will be able to receive a document confirming your registration as an individual entrepreneur.

When filling out the application, you need to select and indicate the code for your future activity according to the all-Russian classifier of types of economic activities. To do this, you should carefully study the classifier and select all the codes that suit you at the moment and those codes that you plan to use in the future.

In addition, it should be borne in mind that when registering an individual entrepreneur, the taxation system is automatically set to general. In order to change it, it is necessary within three days, after you have registered, you must write an application to change the tax system.

The general tax system is the most labor-intensive in terms of accounting and taxes on it are quite high. For the production of colored stones, it is worth choosing a simplified taxation system (STS). It comes in two types – with and without expenses. In the first case, you will pay 15% tax on net profit, and in the second - 6%, but on the entire turnover. What is more profitable for you is up to you personally.

Technology

In order to paint crushed stone according to technology, it is enough simple devices and simple steps:

• dividing crushed stone into fractions (this stage can be avoided if you buy fractional crushed stone);
• painting crushed stone in a mixer (concrete mixer);
• drying stones.

Let us consider in more detail all stages of the technological process.

1. The first stage of the process is the division into fractions. For this purpose, special sifters are used, which must be purchased. This stage can be avoided by purchasing a certain fraction of crushed stone, but this will lead to an increase in the cost of your products. This is due to the fact that crushed stone separated into fractions costs several times more than undivided crushed stone.
2. In order to paint the stones, concrete mixers are used. The stones are loaded into a concrete mixer together with paint and mixed for 20-40 minutes. A little advice: If possible, it is worth purchasing several concrete mixers to speed up the production process. Here the question arises - “how to paint crushed stone?”, but more on that later.
3. To dry, the painted crushed stone is unloaded onto a metal grid and dried. If the production is small, then the crushed stone can be dried simply in air. When volumes increase significantly, special drying chambers or bunkers are used for drying.

Equipment

In order to organize production, you need to buy at least a minimum set of equipment. It is imperative to buy at least one concrete mixer, and preferably several. Ideally, there should be as many concrete mixers as there are colors in color scheme the crushed stone you produce. In addition, crushed stone can be separated into fractions using manual sifting.

As mentioned, buying a sifter can be avoided, but purchasing one is highly recommended. Despite its cost, about 80 thousand rubles, it will pay for itself quickly enough. Its quick payback is due to the fact that the price of crushed stone divided and not separated into fractions differs several times.

To make the drying process faster, you can purchase a drying chamber. At first, there will be no particular need to purchase it. When you begin to expand production, then the issue of purchasing a dryer will arise. If you are making small volumes of crushed stone, then you can simply dry it in a dry, well-ventilated area.

Naturally, it is necessary to purchase small equipment such as shovels, sieves and the like. In addition, it won’t hurt to purchase work gloves and other small items.

Staff

In order to organize a mini-production for the production of painted crushed stone, it is quite possible to do without hired workers. If you do not plan to work independently, but are only going to engage in administrative activities, then you cannot do without workers.

With average production volumes, you will only need four employees who will work every other shift. The qualifications of the workers are practically irrelevant. Any physically strong man can load crushed stone into a concrete mixer and unload it.

Raw materials

For production finished products you will need to purchase raw materials. Colored crushed stone consists of crushed stone itself and dye applied to it.

It is clear that the main raw material is crushed stone. You will buy tons of it. It is advisable to carry out preliminary preparation of the stones before staining, namely, rinse them. This preparation will allow you to obtain a more saturated color.

It is important to remember that the stones must be dried before painting.

Dye is also a raw material, but you won’t buy tons of it, of course. In addition to the coloring pigment, you will also need a binder. PVA glue usually serves as the current binding base. Sometimes polymer paints for crushed stone are used for painting.

Business plan

In order to open a mini-production in your garage, you will need a minimum investment. It will be enough to buy 10 tons of crushed stone, costing 15-20 thousand rubles, the dye for it will cost about 10 thousand rubles. You also cannot do without a concrete mixer, which costs about 9 thousand rubles. In addition, you will need sieves and shovels.

In general, organizing production in your own garage will cost you about 50 thousand rubles. Considering the profitability of such production, you will be able to recoup your investment in less than 3 months of work.

If you plan to open a large production facility, then the costs could be about 900 thousand rubles. This amount includes equipment, raw materials, rent and wages for workers. Such investments will pay off fairly quickly - within 6–9 months.

Room

For such an organization, in order to comply with the technology for the production of colored crushed stone, even a garage or shed is enough. All this can be organized even at home.

If you are going to engage in serious production, then you should choose premises in the industrial part of your settlement. The size of the room will depend on the scale of your production.

It is important that the premises have access to heavy vehicles and trucks. Your main raw material, crushed stone, will be delivered by heavy trucks.

It is necessary that the premises have electricity, water supply and sewerage. Electricity is better with a voltage of 380 watts.

Advertising and sales

In order for production to be profitable, it is necessary to establish sales of finished products. To achieve established sales channels, you need to make yourself known to the consumer.

Depending on the production volume, it is necessary to develop an advertising campaign. If you are planning a fairly large business, then you need to conduct fairly large-scale advertising. Here billboards, advertising on transport, in media will come to your aid. mass media and advertising brochures.

If the production is small, then it is better to work to order. To find clients, you can use a tool such as bulletin boards on the Internet. You need to create your own website.

Given the somewhat seasonal nature of this business, it is necessary to take care of orders during the so-called low season. To do this, it is worth offering your clients a service such as storage of paid goods “until demand”. This will allow production to be loaded throughout the year, and not just during the warm seasons, when people en masse are engaged in landscaping.

conclusions

The most important component that will ensure the quality of the finished product is paint for painting crushed stone. It is she who should be chosen quite meticulously. It must be resistant to ultraviolet rays, since crushed stone is mainly used outdoors.

Landscape design has a wide range of possibilities and techniques used. In this case, unique compositions are created, which often require the use of original materials. In this regard, colored crushed stone has gained enormous popularity, with which you can create real masterpieces landscape design. The production of colored crushed stone as a business idea is a very promising and profitable niche that can pay for itself very quickly with small investments.

Technology for the production of colored crushed stone

Crushed stone is one of the main materials used in construction. It is part of cement-concrete mixtures and asphalt concrete; it is indispensable during the manufacture of reinforced concrete structures and during road construction. More recently, a couple of decades ago, crushed stone began to be used as a decorative material.

Crushed stone, usually granite, is specially painted using the fine fraction of stone. After dyeing it becomes smooth. The paint used for this purpose withstands temperature changes, high humidity, bright sun and other influences.

Painted crushed stone is called painted pebbles, gravel, decorative colored stone. This one is packed construction material in bags weighing 20-25 kg. It is bought for decorating garden plots, burial sites, interior decoration, in aquariums, etc.

Where to start producing painted crushed stone?

To launch the production of colored crushed stone, it is necessary to understand the commercial benefits of this type of activity. One ton of raw materials (crushed stone) costs 2,000 rubles, one bag of colored crushed stone costs 600-700 rubles. Accordingly, by packaging such a product in bags, you can make good money. Since the price of colored stone is much higher, its production will give a good profit.

Crushed granite (marble) undergoes a painting process with a special dye. The next stage of production is its drying, then packaging and shipping to consumers. The best coloring agent for this material is acrylic dye.

Accordingly, to start production you need to purchase equipment and tools, as well as choose a location for production.

What equipment will you need?

In order to open the production of colored crushed stone you need to find a suitable room or area with a canopy with dimensions of about 300 sq.m.

To get started you will need to purchase:

• installation or room in which painted crushed stone will be dried, a well-ventilated room;
• vibrating screen VG-1, or similar equipment, 1 pc. – 90,000 rub.;
• concrete mixer (painting hopper, 1 piece - 8,000 rubles;
• paint – 200 kg;
• crushed stone - 3 tons.

Documents required for organizing the production of colored crushed stone

In order for your business producing colored crushed stone to comply with the requirements of the legislation of the Russian Federation, you must register with the tax office, funds (social insurance, pension, medical insurance) and Rosstat.

But, before you start preparing the documents, you must choose a legal form for your business. If there are no other founders besides you, and you do not plan to create a huge enterprise, then it is enough to register as an individual entrepreneur. To do this you need:

• Write an application to the Federal Tax Service.
• Pay the state fee.
• Prepare a copy of your passport and TIN.
• Choose a tax system.

In addition, you must indicate the code for your activity, according to the all-Russian classifier. In this case, the following are suitable:

• OKVED 26.70– processing of decorative stone;
• OKVED 26.82– production of other non-metallic and mineral products.

To register an LLC, you need to additionally prepare papers on creating a company, resolve the issue of a legal address and form an authorized capital.

In addition to documents confirming the registration of an LLC or individual entrepreneur and the fact that you are a tax payer, you need to obtain permits from Rospotrebnadzor and the fire inspectorate.

And good news for novice entrepreneurs who decide to start producing colored crushed stone. For this type of activity, in addition to the above list of documents, no need to obtain additional permits and licenses.

Optimal tax regime

For enterprises specializing in the production of colored crushed stone, experienced businessmen recommend choosing a simplified taxation system. The amount of tax liability can be calculated in two ways:

1. 6% of total revenue (gross income);
2. 15% of the difference between gross income and enterprise costs.

Note! When calculating the amount of taxes, take into account only those expenses that are supported by documents. If you decide to work on the simplified tax system, you need to write to tax office a corresponding application and submit it along with documents for company registration.

Another important point. If you are planning to create a large enterprise that will employ more than 100 people, then you will have to work under the general tax regime.

How much money do you need to start a business?

If you don’t have enough money to purchase equipment, you can work without noise for the first time. Sifting of crushed stone can be done manually through meshes of a certain external size. You also don’t have to buy a drying chamber at first; you can dry the crushed stone outdoors. In this case, you will only need a concrete mixer for uniform and high-quality coloring of crushed stone.

A small set of equipment suggests that project for the production of colored crushed stone is low-cost. It will be enough to invest about 100,000 rubles in this business idea to start your own production.

Even if this amount is not available, you can purchase a minimum of equipment and do some of the work manually. When funds become available after the sale of finished products, it will be possible to gradually replenish the staff.

Another positive point is that two unskilled workers can be hired to complete the work, even if they have no work experience.

D To purchase equipment you need about 90,000 rubles.

Raw materials per 1 ton of finished painted crushed stone will cost:

• granite crushed stone (or marble), 1 t – 2,000 rubles;
• acrylic paint (200 rubles/kg), consumption 20 kg per 1t of crushed stone – 4,000 rubles;
• buckets – 2 pcs (for raw materials and finished product– 600 rub.;
• shovels – 2 pcs for 2 workers – 800 rubles;
• bags (10 rub./pc.) for packaging the finished product 50 pcs. – 500 rub.

The total amount of funds needed to purchase raw materials is 7,900 rubles.

How much can you earn from crushed stone production?

One ton of colored crushed stone sold at retail costs about 30,000 rubles. Without taking into account the cost of fixed assets (90,000 rubles), the profit per ton of finished products will be 30,000 – 7,900 = 22,100 rubles.

This does not take into account taxes, fees, expenses for an advertising campaign, transportation costs, rent of premises, sites. All these expenses will amount to about 50% of the investment. For a business with small investments, these are pretty good numbers. It can pay for itself in one season of work - 8-9 months.

Features of the production of colored crushed stone

Any production that wants to be successful must have customers for the continuous sale of its products. No exception business idea for the production of colored crushed stone. Before starting this project, you need to research the market and the demand for such a product in a particular region in order to be confident in the possibility of sales. It is necessary to establish contacts with landscape design companies in order to sell your products to them. Some part of it can be sold through construction stores or via the Internet.

The business idea for the production of multi-colored crushed stone is based on the acquisition of raw materials of medium fraction 10-30mm and its further painting with acrylic paint. As a result of this simple operation, a material that is very popular today for landscape design is obtained.

The essence of the business of producing multi-colored crushed stone

The business of producing colored stones for landscaping is based on painting ready-made and sorted raw materials.

The finished material is widely used in:

• landscape design of private households,
• in the improvement of urban areas,
• organizing a comfortable microclimate in the aquarium and terrarium,
• when arranging tombs and cemetery plots.

This material is usually sold in large quantities. To reproduce a landscape design project for city and park areas, tens of tons of colored stone are required, when landscaping adjoining and personal territories, no less, even for the arrangement of a standard cemetery plot, at least a ton of colored crushed stone will be required.

Main consumers

• Private persons for arrangement adjacent areas and personal plots,
• Utilities and “green farms” to create spectacular flower beds and lawns,
• Landscape design companies
• Organizations offering funeral services - arrangement of cemetery territory.
• Pet lovers (for aquariums, terrariums, cages),
• Pet shops and pet salons (to recreate a spectacular environment for animals).

Production process for painting crushed stone

1. Acquisition finished, sorted raw materials of the middle fraction (10-30mm). Purchasing crushed stone of a specific fraction eliminates the need to sort it. It is placed in a raw material hopper, from where it is fed in portions using shovels for painting. It is not advisable to store it outdoors, since a dirty stone cannot be properly painted. Acrylic paint fits perfectly on a dry and clean surface. Raw material purchased in a volume of 10 m3 (about 14 tons) - this is the standard volume of KAMAZ, which usually transports crushed stone.
2. Placing it in the paint bin, the role of which is played by a concrete mixer. When using a concrete mixer with a volume of 0.7 cubic meters, its capacity is not filled to the top, but a little more than half, about 0.5 cubic meters. Together with crushed stone, it is poured into a concrete mixer acrylic paint For facade works the desired shade. To produce finished material with a volume of 2 tons per shift, the concrete mixer will have to be started 3 times a day. Using a concrete mixer of a smaller volume (let's say 0.2 cubic meters) is less cost-effective, since to paint the same volume - 2 tons - it will have to be started 6 times a day (the calculation is made taking into account the weight of 1 cube of crushed stone = 1.41 tons).
3. Direct painting. The process of operating the concrete mixer itself takes no more than 15 minutes. Immediately upon completion, the painted, raw material must be dried and excess paint allowed to drain off.
4. Drying the finished material using a vibrating sieve. To dry freshly painted crushed stone, you need a large sieve that can easily accommodate material weighing about 700 kg (one batch from a concrete mixer). This sieve should be equipped with a tray onto which excess paint will drain. Vibrating sieve with pallet in this regard perfect option. Painted pebbles must have an even color and be perfectly clean. When a ton of painted crushed stone costs 24,000 rubles (ordinary, unpainted crushed stone costs 1000-1100.00 rubles per ton), the buyer will be picky about its quality, so drying should be taken seriously.
5. Warehousing finished material. For storing and storing finished material, a bunker is used, similar to the one in which raw materials are stored. It will not be possible to store such expensive material in the open air - it must be packed in bags dry and clean.
6. Packing in bags. The finished material is packaged in bags designed for a weight of 5 to 20 kg. This is done manually using shovels. The bags are sewn up using a portable bag sewing machine.

What equipment is required for the production of colored crushed stone?

To produce colored crushed stone from ready-made raw materials, you will need little equipment and, accordingly, small investments.

• Bunker for raw materials,
• Concrete mixer for painting,
• Vibrating sieve for drying and draining excess paint,
• Bunker for finished material,
• Bag stitching machine

The table below describes a set of equipment designed for minimum performance and characterized by the lowest cost.

Total: 870,990 rubles.

The set of equipment given in the example allows you to produce up to 10 m3 (13 tons) of colored crushed stone per work shift. Considering the working volume of the Prof-BS700 concrete mixer is 0.7 m3, the painting time is no more than 15 minutes per batch and the drying time using a vibrating sieve is no more than 5 minutes per batch, it will not be possible to process a larger volume of raw materials.

Additional equipment and consumables

Shovels. To paint crushed stone you will need the paint itself - acrylic, at least 2 shovels for transferring the raw materials from the bunker into the concrete mixer, from it to the vibrating sieve, and from there into the bunker for the finished material. Four shovels for 1360 rubles. (340 rubles each).

Dye. Considering the productivity of 2 tons per day (44 tons per month), about 310 kg of paint will be required at an average cost of 110 rubles. per kg. Total for 34,100 rubles of paint per month.

Colored crushed stone is packed in 20 kg bags. Accordingly, 2,200 bags of 4.5 rubles are needed per month. a piece. Total - 9,900 rub. per month.

Total additional costs:

• The total cost of the tool is 1360 rubles.
• Price Supplies for 1 month of work - 44,000 rubles.

Feasibility study of the project

The total cost of opening and launching the production of multi-colored crushed stone will include the cost of the necessary equipment, tools, basic raw materials and consumables (paint and bags).

How much money will you need to start a business?

• Purchase of equipment and tools - RUB 872,350.00.
• Purchase of raw materials (crushed stone, paint, bags): RUB 100,000.
• Registration with the INFS and other expenses for starting a business - 50,000 rubles.

Total: 1,002,350 rubles.

How much can you earn from this?

Revenue was calculated taking into account productivity 2 tons per shift and 22 shifts per month.

How much crushed stone do you need to sell per month to reach the break-even point?

Given the gross profitability of the activity in the amount of 480% and the presence of total fixed expenses in the amount of 200 thousand rubles, in order for the activity to reach the level of self-sufficiency, it is necessary to sell 250 thousand rubles per month, i.e. about 20 tons of products.

Colored crushed stone and decorative chips are used in landscape design and in creating a favorable microclimate in terrariums and aquariums. The production of colored crushed stone and chips is quite profitable, since the unpainted version - the raw material - is much cheaper than the final version.

The raw materials used are marble crushed stone, granite or marble chips, or gravel or sand.

• private individuals using building stone for landscaping adjacent areas;
• municipal organizations and city landscaping services for the design of lawns and flower beds;
• companies performing specific landscape creation work;
• organizations of funeral services performing arrangement of cemetery plots;
• pet owners who purchase colored crushed stone and chips to provide a natural microclimate for aquariums and terrariums;
• pet store owners to create a spectacular environment.

Manufacturing technology

Crushed stone of a fraction from 10 to 30 mm is suitable as a raw material, and various paints, as well as various binders, can be used to impart color. The principle of manufacturing products does not involve any complex operations, as a result of which we obtain a product that is quite in demand in modern construction material for creating landscape design - multi-colored stone.

Process video:

1) It is planned to purchase specially selected raw materials, medium-fraction stones, in the range from 10 to 30 mm. When purchasing crushed stone of a specific fraction, there is no need for additional sorting. The material is stored in a bunker, from where it is shipped for painting as needed. Shovels are used for batch loading. Storing crushed stone without cover is not recommended, as the pores of the stone become clogged, and the quality of painting suffers as a result. To apply paint, it is necessary to ensure a dry and clean surface of the material. Based on the volume of transportation, which is most often carried out by KAMAZ, a one-time delivery of cargo equates to a volume of about 14 tons (10 m3).

2) The delivered crushed stone or crumbs are placed in a painting hopper, the function of which can be performed by a concrete mixer. If the standard volume of a concrete mixer is 0.7 cubic meters, and it is not filled to the brim, but slightly above half, then the crushed stone occupies approximately 0.5 cubic meters. Paint is added to the material in one container. To get 2 tons of finished material during a shift, the concrete mixer must work three cycles. Reducing the volume of raw materials loaded into a concrete mixer is impractical: the profitability of production will decrease, since to obtain the same volume of finished products it will be necessary large quantity concrete mixer operating cycles. In practice, it looks like this: 0.2 cubes need to be run 6 times to get a result of 2 tons (in this case, a cube of crushed stone/crumbs is 1.41 tons).

4) Next, if, for example, granite chips are used, then they are sifted through a vibrating sieve. It is ideal to use a sieve with a tray. After dyeing, each pebble should have a uniform color and be clean. If we compare ordinary and painted crushed stone, the difference looks like this: a ton of colored colored crushed stone costs 22-24 thousand rubles, and a ton of unpainted crushed stone costs 1,000 rubles. Of course, the buyer will carefully analyze the quality of the product, so it is unjustified to be careless in drying technology.

5) The finished colored crushed stone or decorative chips are stored using for this purpose the same bunker as for storing raw materials. Storing expensive products without packaging and protective coating is out of the question. It is packaged dry and clean.

6) Tara. Traditional packaging is bags designed for loads from 5 to 20 kg. The packaging process is carried out manually and with the use of an auxiliary tool (shovel). Filled bags are healed using a bag sewing mechanism.

Equipment for the production of

The production of multi-colored crushed stone does not require large investments if ready-made raw materials are used.

Equipment includes:

• bunker No. 1 (for raw materials);
• concrete mixer (for painting);
• vibrating sieve (for sifting);
• bunker No. 2 (for finished products);
• device for sewing bags.

Equipment is selected taking into account maximum productivity and lowest cost.

Two bunkers for bulk building materials with a capacity of 10 m3 will cost 300,000 rubles; domestically produced concrete mixer – 200,000 rubles; vibrating sieve – 40,000 rubles; bag sewing device (preferably made in Belgium) – 40,000 rubles.

The above set of equipment for the production of colored crushed stone is designed to produce products in a volume of 10 m3 per shift. Based on the capacity of a concrete mixer, for example, the Prof-BS700 brand, which produces 0.7 m3 of product in a quarter of an hour, and the drying time for each batch, which is about 5 minutes, it will not be possible to obtain more.

Additional equipment and consumables

To paint stone, you need a dye and at least two shovels intended for loading raw materials into a concrete mixer, from it into a vibrating sieve, and then into the finished product bunker. If the cost of a shovel is about 300 rubles, four shovels will cost 1,200 rubles.

Since the paint and binding materials may be different, the prices for them are different. Most likely, you will have to experiment with dyes in your search best option for your business producing colored decorative stones.

Painted crushed stone or crumbs are packed in 20 kg bags. Thus, about 2,000 bags will be required per month, costing 9,000 rubles per month.
