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.

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.
