In the case of normal pressing of wood pellet, the life of the wood pellet press roller assembly of the wood pellet machine is 300-500 working hours. However, there are many factors that affect the life of the wood pellet machine press roller assembly of the wood pellet machine.

First, the amount of sand in the material. If the material contains more sand and soil, the working time of the wood pellet machine press roller assembly is only 400 hours.
Second, The material of the wood pellet press roller assembly of the wood pellet machine. The material of the wood pellet press roller assembly of our company's wood pellet machine is 65 manganese steel, which is completed by forging - rough turning - heat treatment (72 hours) - fine turning and other processes. Each step affects the hardness, wear resistance, and stiffness of the wood pellet press roller assembly of the wood pellet machine.
Third, The gap between the wood pellet machine press rollerer assembly of the wood pellet machine and the ring die of the wood pellet machine. If the gap between the ring die and the wood pellet machine press roller of the wood pellet machine is 1mm, the working time is only 300 hours, if the gap between the press roller assembly and the ring die of the wood pellet machine is 3mm, the working time can reach 500 hours, while paying attention to the size of the output of the wood pellet machine.
Fouth, Density of materials. If the pressing is eucalyptus sawdust, the working time can reach 300 hours, if the pressing is pine sawdust, the working time can reach 400 hours, if the pressing is poplar sawdust, the working time can reach 500 hours.
