Biomass briquetting machine is a kind of equipment that presses biomass raw materials such as crop straw, sawdust into lump fuel, which is widely used in the field of biomass energy. In order to ensure the efficient operation of equipment and product quality, the selection and treatment of raw materials is particularly important. So, what are the specific requirements of biomass briquetting machine for raw materials?

1. Moisture content of raw materials

The moisture content of raw materials is one of the important factors affecting the operation efficiency of briquetting machine and the quality of finished products. Generally speaking, the suitable moisture content range is between 10% and 15%. If the moisture content of raw materials is too high, it will be difficult to form in the process of briquetting, and may even cause equipment blockage; However, if the moisture content is too low, it will affect the compactness and strength of the compact. Therefore, before using biomass briquetting machine, raw materials need to be properly dried or humidified to achieve ideal water content.

2. Particle size of raw materials

The particle size of raw materials directly affects the forming effect of briquetting machine. Under normal circumstances, the particle diameter of raw materials should be controlled below 5 mm and the length should not exceed 10 mm. If the particles are too large, it may lead to equipment jamming or molding difficulties. Therefore, users need to crush the raw materials before use to ensure that their particle size meets the requirements.

3. Types of raw materials

Biomass briquetting machine is suitable for various types of biomass raw materials, including crop straw (such as wheat straw and corn straw), sawdust, rice husk and peanut shell. However, it should be noted that the fiber structure and composition of different raw materials are different, and its molding effect will be different. For example, sawdust and is easier to form because of their fine fiber structure, while rice husk may need to add a certain proportion of adhesive to improve the forming effect because of its smooth surface.

4. Cleanliness of raw materials

In order to protect the equipment and improve the quality of finished products, the raw materials should be kept as clean as possible and should not be mixed with too many impurities, such as sediment, stones and metal fragments. These impurities will not only damage the equipment, but also affect the combustion effect of the finished fuel. Therefore, it is recommended to screen and clean the raw materials before use.

5. Uniformity of raw materials

The uniformity of raw materials is also an important factor affecting the briquetting effect. If the raw materials of different kinds or different states are mixed unevenly, the quality of finished products will be unstable. Therefore, when mixing a variety of raw materials, we should ensure their uniform proportion to ensure the consistency of briquetting effect.

In a word, reasonable selection and treatment of raw materials is an important prerequisite for using biomass briquetting machine. Only by meeting the above requirements can we give full play to the performance of equipment, improve production efficiency and product quality, and contribute to the development of green energy.
