How briquette presses work: technology overview

Every year the world is developing steadily and people are trying to improve existing technologies and methods of their use. Resource efficiency is a major priority, which is becoming more and more important every day. Materials recycling technologies have taken one of the leading places in the modern world. One of these technologies is briquetting. This is a process that allows you to convert waste from various industries into a useful product. Briquette presses are a key element in this process, because it is thanks to them that you can combine small particles of raw materials or secondary materials into dense, compact briquettes. Subsequently, the resulting briquettes are convenient and easy to use, which gives them an additional advantage.

Stages of the briquettes process

In essence, the briquettes process consists of three main stages, namely – grinding, drying of raw materials and briquetting itself. To explain this point in more detail, let’s take the wood briquettes process as an example. But remember, the raw materials can be different.

Grinding

Wood chips of different sizes are fed into the crusher. A crusher is a special machine that is used to grind wood waste into small fractions. Of course, crushers come in different types, so you need to consider this nuance. Inside the machine, the grinding process takes place and the material is unloaded in bulk or into a vehicle.

This process is very important, because the homogeneity of the mixture depends on it. Small particles of raw materials mix better with each other and with other additives. This, in turn, guarantees the homogeneity of the briquettes. Also, smaller particles entering the fuel briquette press are easier to compress, which reduces the energy consumption of the process.

Drying

The next stage is drying. This stage is critically important in the briquettes process, as the moisture content of the raw material can significantly affect the quality of the finished briquettes and the efficiency of the process itself. The optimal moisture content of the raw material before briquetting depends on the type of raw material itself and the briquetting technology, so you need to start from this information. It is important to understand that further work depends on the drying stage, which is why it is so important.

Stages:

• Methods of drying raw materials can vary. Let’s start with contact drying. The raw material comes into contact with a heated surface, for example, drums or a belt. This method is quite simple, but has its own nuances. We are talking about limited efficiency, which can lead to overheating of the surface layers of the raw material.
• Convective drying consists in drying the raw material with a stream of hot air. This method is more efficient than the previous one, but requires more energy.
• Radiation drying is also one of the options. In order to dry the raw material, infrared rays are used. This method allows you to dry the material quickly and evenly, but it is worth noting that this option will be more expensive.
• The last on the list will be a combined option. This is a combination of different drying methods to achieve optimal results and efficient production.

You also need to pay attention to important factors that affect the drying process. We are talking about the type of raw material, namely moisture content, particle size and heat capacity. The drying temperature should be chosen based on the properties of the raw material to avoid damage. Also consider the air flow rate, as it affects the intensity of moisture evaporation. And the last but not the least important factor is the drying time. You need to focus on the initial moisture content of the raw material and the desired final result.

Briquette presses – briquetting process

Briquetting is the final stage during which you will receive the finished product. After the above preparatory stages, mixing and dosing take place. Binders increase the strength of the briquettes when added to the prepared raw materials. The process thoroughly mixes the components until they form a homogeneous mass. Workers load the finished mixture into a special container for further pressing.

The mixture is fed into the briquettes press and subjected to powerful pressure in the press. The pressure ensures compression of the material and its transformation into briquettes. The briquetting process can be both mechanical and hydraulic.

When the briquette machine completes its work, the finished briquettes come out of it and are sent for packaging and further transportation. They are usually packed in packs.

Energy-efficient boilers and their advantages

With the arrival of winter, cold snaps and frosts are rapidly approaching. A serious question arises about effective and economical heating. Every year, the cost of heating increases and significantly affects the budget of entrepreneurs, which in turn makes you think about finding ways to reduce the financial burden. Energy-efficient boilers are a way to solve this problem, because this heating system allows you to significantly save money while creating comfortable conditions for the company’s employees. By choosing this heating option, you immediately choose an effective direction for energy savings.

What is an energy-efficient boiler ?

An energy-efficient boiler is a type of modern heating equipment that is responsible for efficient and reliable heating of water or air, thereby creating a comfortable temperature in the room. Its main advantage and a key factor why entrepreneurs choose it is the ability of the boiler to minimize energy costs during operation. It is worth emphasizing that energy-efficient boilers usually have a higher efficiency factor compared to the traditional boiler version.

Energy-efficient boilers – advantages of use

• The first and very significant advantage of using this equipment is the economic benefit, namely saving money and reducing fuel costs. This factor is one of the key factors in making a decision to use energy-efficient technologies and ecological heating. Fuel consumption is significantly reduced. Thanks to the optimal heating and air conditioning regulation system and insulation of premises, heating is effective.
• The environmental aspect is no less important, because industrial solid fuel boilers have a low level of emissions of harmful substances into the atmosphere of the earth. In boilers with this option, wood, briquettes, pellets and coal are burned, which is quite environmentally friendly. By choosing energy-efficient boilers, entrepreneurs reduce the use of such energy sources as gas or oil. This, in turn, reduces dependence on imports and ensures stability of heating.
• The next significant advantage is the ability to burn secondary materials in solid fuel boilers. We are talking about wood or straw residues. This significantly reduces the amount of secondary materials that can accumulate or go to landfills.
• Long service life is a significant advantage for entrepreneurs and owners of large-scale production. For example, boilers in our production are distinguished by their wear resistance and reliability in operation. This purchase will be a good investment in the development of your enterprise and will provide comfortable working conditions for workers.

How do I choose an energy-efficient boiler?

• First, you need to assess the size and parameters of the premises that you want to heat with a boiler. Consider the level of thermal insulation of the building, the number of windows, and the condition of the walls and roof. It is important to understand the level of thermal insulation, because thanks to this data you will know what power the boiler needs.
• Pay attention to the energy efficiency of the boiler, it is worth choosing options with a high coefficient of efficiency.
• Make sure that the manufacturer is reliable. It is important that the boilers are manufactured in accordance with all standards and from high-quality materials, because their serviceability and durability depend on this.
• Consider your budget, because this will help significantly narrow down the search. Although energy-efficient boilers are a worthwhile purchase, they are still undoubtedly profitable and will pay off in a fairly short time.

Biofuel equipment

Biofuel equipment – pressing machines have received a special capacity in enterprises whose activities are accompanied by the accumulation of large volumes of waste. In addition, the processing of secondary raw materials has occupied its niche as a profitable business. The profitability of which increases with the operation of high-quality and reliable equipment.

Briquetting press: advantages

Modern pressing systems have the following advantages:

• The possibility of reducing the volume of secondary raw materials up to several times, which reduces the frequency of their removal from the territory;
• Manual sorting of waste allows you to hand over raw materials for good money;
• Keeping warehouses clean and even reducing the cost of waste disposal.

An important advantage of the equipment is also the creation of fire-safe fuel briquettes.

Biofuel equipment. Why do you need to buy a PB-48 briquetting press?

Before buying equipment, you need to decide why you need the unit. The main goal: there is a certain amount of waste, and it is necessary to dispose of it, and it is good to make money from it. In European countries, the briquetting press is produced with a capacity of up to 50 kg per hour. The payback period of such a device is about 7-10 years.

Despite this, the equipment is widely in demand in Europe but not in Ukraine. This is due to the fact that the EU countries have rather strict requirements for waste processing, moreover; these requirements are supported by the imposition of high fines for their violation. Therefore, it is more economical for a small German company with waste up to 300 kg per shift to install a small briquetting press, which has a productivity of 30 kg per hour. Then to pay a large amount for the removal of waste for disposal. Such a situation in Ukraine is completely different. It is often cheaper to take waste to a landfill than to buy a PB-48 briquetting press. The cost of which can pay off in the long run.

Material for fuel briquettes

The PB-75 briquetting press is created on the basis of rational pressing technologies, which ensure minimum electricity consumption during its operation. In addition, the device is able to produce briquettes from the following types of raw materials:

1. Sawdust;
2. Rape straw;
3. Hay;
4. Cereal straw;
5. Popping of sunflower seeds;
6. Buckwheat husk, etc.

Since the heating period in our country can last about 5 months. Gas prices are regularly increasing, sooner or later briquettes will be in mass demand.

Briquetting press for biofuel

In the conditions of modern life, biofuel is produced directly by processing waste wood, straw, husks of various cereals and seeds, as well as other natural components. The remaining part of the fuel market belongs to liquid fuels made from oils of animal and vegetable origin.

Liquid types of biofuel

The production of liquid biodiesel involves the use of special equipment. It is used to react natural materials with methyl alcohol. During the procedure, a process occurs using alkaline or acidic enzymes. The duration of the reaction is several minutes. The production process is simple, but it requires special technological equipment.

The method of creating fuel briquettes from solid raw materials

This type of biofuel is a granular raw material. People widely use it in the electric power and thermal power industries for heating the coolant and producing electricity. Production of granules requires the use of equipment designed for the following technical processes:

• Preparation of material from wood for the production of biofuel, which grinds the elements to a size of 25 mm;
• The process of drying sawdust to 10% moisture in drum or belt type drying equipment;
• Additional grinding of the prepared material at the expense of vibrating mills, chipping machines;
• If the raw material has optimal moisture and fractional composition, specialists do not use the grinding and drying process;
• Auxiliary moistening of raw materials, which increases the density of pressing;
• Compression of material using a briquetting press.

The raw material should not have a moisture content of more than 12%, contain more than 5% rot, and the particle size should be less than 5 mm. The equipment creates fuel briquettes by raising the temperature of raw materials and gluing the particles with natural glue. The finished products are cooled, packed and packed. The cost of such fuel is calculated based on the type of material (sawdust, husks, straw), costs for technological processes and packaging.

Briquetting press PB-48

The equipment produces fuel briquettes from sawdust, sunflower husks, and other plant waste, such as cereal crops, straw, and bean tops. The natural lignin in the raw material eliminates the need for additional binding substances during production. The PB-48 briquetting press compresses the briquettes with the help of strict molding in a cylindrical guide with a press inflow of material. The resulting pressure ensures the sintering of the raw material into a solid mass in the form of a continuous sleeve without the inclusion of binding elements in the composition. Pressing takes place in conditions of high temperature, so the briquettes become strong, their surface is melted.

Briquetting press PB-75

The main factors that distinguish the PB-75 briquetting press from the PB-48 equipment model include:

1. Extreme simplification of the structure of nodes and parts that wear out quickly;
2. Availability of spare parts and components;
3. maximum automation of all technological processes;
4. Simplicity and ease of repair and maintenance of the device;
5. Maximum reduction in the number of parts that wear out quickly.

The design of the PB-75 press allows you to freely approach the repair and maintenance of the unit. In addition, all spare parts and components for both models of equipment are always available.

Pellets and briquettes are a benefit of production

If you wish to produce compressed biofuel from wood sawdust, sunflower husks, flax processing waste, grain crops, etc., options such as briquettes and pellets are available to choose from. However, the best solution will be to focus on creating one type of product. So, which is more profitable, making pellets or fuel briquettes?

Aspects of pellet production in industry

According to the types of waste generated in production, the pellets created are classified into the following categories:

• High quality (DIN+ standard);
• Industrial

The first option is accompanied by the production of white pellets, which include a small amount of ash. This can be achieved using the raw material of woodworking waste without bark. One of the most common sales methods is the sale in bags of up to 25 kg. When the method used in the enterprise does not include cleaning of the bark or the owner faces the goal of processing convex boards with bark and low-quality chips, the businessman needs to think about the production of industrial pellets and briquettes. Industrial pellets have found their application in the form of solid fuel, if the composition contains small amounts of ash, and are also needed for domestic purposes, such as hygienic filler for cat litter.

Fuel briquettes – production features and advantages

Briquettes made using the PB-48 briquetting press have become widespread. Their production is much cheaper than pellets. The product can be used in any ovens, boilers and fireplaces that are not equipped with special burners. The PB-48 briquetting press allows you to create fuel briquettes that have the following advantages:

1. Ease of use;
2. Do not spark and do not shoot when burning;
3. Saving storage space;
4. Moisture resistance;
5. High heat output.

Ready-made briquettes are popular both in the domestic market and outside of Ukraine. The main advantage of this type of biofuel is the possibility of using wood waste of almost any quality for its production. The advantage of using pressed material is that its density is twice that of wood. Such biofuel will require half the storage space. The temperature during pressing stimulates the melting of fuel briquettes, which ensures their strength and facilitates their convenient transportation. In addition, the PB-48 briquetting press creates biofuel without binding substances. Gluing is ensured due to natural legin contained in the composition of raw materials.

What are heating briquettes made of?

Despite the fact that gas and electric heating devices and heating briquettes have firmly established themselves in human life, solid biofuel also remains in demand. It continues to be used for heating private and country houses, as well as for lighting baths and fireplaces. Often, solid fuel stoves are irreplaceable in high-rise buildings where natural gas has not yet been installed.

Wooden heating briquettes

Fuel blocks (Euro fuel) have long been used worldwide. After all, it has been proven that the use of wooden beams is irrational, and the consumption of natural elements is uneconomical. Pressed briquettes help solve the difficulty. The production of wood fuel Eurowood uses waste from the woodworking industry, heats it to a certain temperature and presses it under high pressure. For the process, a briquetting press PB-75 or other models is used. Some believe that a special glue is used in production, but this is not the case. During pressing, hot shavings release a natural adhesive substance called lignin. This makes the blocks strong and allows them to keep their shape during transportation and storage. This type of biofuel is absolutely harmless to human health when used. The PB-75 briquetting press allows you to create sawdust briquettes, which have the following advantages:

1. The possibility of use for barbecues when preparing food.
2. The smallest amount of smoke than when burning wood.
3. Compact form for easy storage and transportation.
4. Ability to easily plan the amount of fuel needed for the season.
5. Combustion releases an order of magnitude less poisonous CO2 when compared to other types of fuel.

In addition, the higher density of Eurowood ensures their long-term burning. Therefore, you can put 4 times less briquettes in the furnace or boiler.

Briquetting press PB-75 for making husk blocks.

In addition to woodworking waste, fuel blocks can also be created from agricultural waste: straw, leaves, peat, etc. The capabilities of the PB-75 briquetting press also allow the production of fuel briquettes from the following raw materials:

• Buckwheat husk (husk) acts as a natural accumulator of natural energy. This is provided by the petals of the shell of buckwheat grains, which protect them and absorb the sun’s heat. At the same time, the energy potential of the shell increases from the semi-crystalline structure of the protein.
• Linen. Flax briquettes have not yet gained wide demand in the solid biofuel market, but in the case of using high-quality raw materials and a serious approach to their processing, the resulting product will be on a par with common sawdust and straw blocks.
• Husk of sunflower seeds. It is popular because during the production of seed oil, a considerable amount of waste is collected, which has the highest heat output.

The ash remaining from briquettes made of husks or husks makes it possible to fertilize the garden beds well. Eurowood is an ecologically harmless fuel that allows you to solve the issue of eliminating waste from the production of sunflower oil. Briquetting press PB-75 due to high temperature and pressure prevents the blocks from falling apart at the exit. At the same time, the presence of lignin in the raw material makes it possible to dispense with the addition of binding substances, thereby saving money.
