Briquette making machine is a kind of equipment used to press biomass raw materials into briquette fuel. Common raw materials include sawdust, straw, rice husk, wheat straw and so on. The humidity of raw materials has an important influence on the working effect of briquette making machine.

First of all, the high humidity of raw materials will affect the production efficiency of briquette making machine. In the working process of briquette making machine, the high humidity of raw materials will increase the viscosity of raw materials, which will lead to the easy adhesion to the mold during the pressing process, thus increasing the difficulty of mold wear and cleaning and reducing production efficiency. In addition, raw materials with high humidity are prone to adhesion after being pressed at high temperature, which leads to adhesion between finished products and affects the uniformity and stability of combustion.

Secondly, the high humidity of raw materials will also affect the quality of finished products. In the working process of briquette making machine, the high humidity of raw materials will lead to insufficient density of finished products, which will easily lead to cracking or fracture, and affect the overall quality of finished products. In addition, in the combustion process, the finished product with too high humidity will lead to incomplete combustion, produce a lot of smoke and harmful gases, and pollute the environment.

Finally, the high humidity of raw materials will increase the energy consumption of briquette making machine. In the working process of briquette making machine, it needs to consume a lot of energy to heat raw materials to a certain temperature for pressing. However, raw materials with high humidity need longer time to be dried, which increases energy consumption. At the same time, because the raw materials with too high humidity need more pressure to form particles or briquettes in the pressing process, it also increases the energy consumption of the equipment itself.

Therefore, in actual production, in order to ensure the processing efficiency and finished product quality of briquette making machine, it is necessary to strictly control the humidity of raw materials. Usually, the suitable humidity of raw materials should be between 10% and 15%, which can be adjusted by drying and other methods. At the same time, it is necessary to clean and maintain the equipment regularly during use to ensure the normal operation of the equipment and prolong its service life.
