In the case of normal pressing of wood pellet, the life of the wood pellet machine ring die is 800-1000 working hours. However, there are many factors that affect the life of the wood pellet machine ring die.

Such as:
1. If the pressed is eucalyptus sawdust, the working time can reach 800 working hours, if the pressed is pine sawdust, the working time can reach 900 working hours, if the pressed is poplar sawdust, the working time can reach 1000 working hours.
2. The amount of sand in the material. If the material contains more sand and soil, the working time of the wood pellet machine ring die is only 500-600 working hours.
3. The gap between the ring die and the press roller of the pellet machine. If the gap between the pellet machine ring die and the press roller is 1mm, the working time is only 800 hours, if the gap between the pellet machine ring die and the press roller is 3mm, the working time can reach 900 hours, while paying attention to the quantity of the wood pellet machine output.
4. Material of wood pellet machine ring die. The material of our company's wood pellet machine ring die is 20 molybdenum titanium alloy steel, which is completed by forging - rough turning - heat treatment (time 72 hours) - fine turning and other processes. Each step affects the hardness, wear resistance, and stiffness of the wood pellet machine ring die.
5. User maintenance. After the new wood pellet machine ring die is installed on the machine, the sawdust and sand containing oil should be used for grinding for 3-5 hours, and the surface of the ring die after grinding will produce an oil film, which will play a good role in the process of pressing the wood pellets.
