Biomass briquette machine is a kind of equipment that presses various biomass raw materials, such as sawdust, rice husk and corn stalk, into block or granular fuel through high temperature and high pressure. This kind of equipment plays an important role in the utilization of renewable energy. However, different raw materials will cause different degrees of wear and tear to the biomass briquette machine during processing, which is caused by different physical and chemical properties of raw materials.

First of all, the hardness of raw materials is one of the important factors affecting wear. Raw materials with high hardness, such as bamboo chips or some hard wood chips, will cause great wear and tear to the mold and spiral parts of the machine. This is because the materials with high hardness need more pressure and longer time in the pressing process, which increases the wear degree of machine parts.

Secondly, the fiber content and length of raw materials will also affect the wear. Raw materials with high fiber content and long fiber, such as some herbs, may be wound on the rotating parts of the machine during pressing, which will lead to poor operation of the machine and increase the risk of wear. Therefore, when dealing with such raw materials, it is usually necessary to cut or crush them first to reduce the wear and tear on the equipment.

In addition, the impurity content in raw materials is also a factor that cannot be ignored. Raw materials containing sand, metal particles and other impurities will significantly increase the wear degree of equipment, because these impurities will cause scratches or wear on the inside of the machine under high pressure. For example, peanuts usually grow in sandy soil, and peanut shells will contain a certain proportion of sand, which will cause great wear and tear to the equipment. Therefore, it is very necessary to screen and clean the raw materials before pressing.

Finally, the moisture content of raw materials will also affect the wear and tear of the machine. Raw materials with too high moisture content are easy to generate steam during pressing, which will not only affect the quality of finished products, but also lead to rust or corrosion inside the biomass briquetting machine, thus increasing wear and tear. Therefore, controlling the moisture content of raw materials in an appropriate range is an important measure to prolong the service life of equipment.

To sum up, different raw materials have significant differences in the wear of biomass briquetting machine. In order to reduce equipment wear and prolong its service life, operators should take corresponding pretreatment measures according to the characteristics of different raw materials, such as adjusting equipment parameters, screening raw materials and controlling moisture content. This not only helps to improve production efficiency, but also reduces maintenance costs.
