The wear of sawdust briquette machine, especially the propeller, has a lot to do with the raw materials used in the production of sawdust briquette machine. For example, when using pure sawdust and peanut shell as the raw materials, the equipment for making peanut shell briquettes wears more serious and the propeller of sawdust briquette machine must be repaired at least every 2 days. While the propeller of sawdust briquette machine for processing sawdust should be repaired every 3-4 days. The main reason is that peanuts are usually grown in sandy soil, and the peanut shells would contain a certain proportion of sand, which would lead to the wear of equipment. If the peanut shells are filtered before making peanut shell briquettes, there will be less wear on the equipment.

From the perspective of energy saving and new energy application technology as well as waste utilization and recycling, sawdust briquette machine is a good project for the benefit of the people, which must be supported and encouraged. The sawdust briquette machine can effectively process sawdust, rice husk, straw and peanut shells into charcoal, which can replace the charcoal made of logs and plays an important role in the protection of environmental forestry resources.
 
Then, how to check if the sawdust briquette machine is out of order?
1. During the production of sawdust briquette machine, the output speed decreases obviously.
2. The moisture content and temperature of raw materials are not up to the requirements, and the wood briquette machine is often stuck and cannot be produce briquettes normally.
3. The briquette can be formed, but it cannot be combined together.
4. The discharging speed is fast, but the structure of briquettes is loose and the density is lower.
5. The wear on the front part of screw propeller is less than 4mm.
6. The diameter of the internal hole of the briquettes is less than 10mm.
7. Parts of the propeller spiral are worn out due to stones, iron, nails and other foreign objects in the raw materials.
