The unusual noise from the first shaft of your pellet mill may be due to aging or damage to the elastic element in your coupling. Today, we'll teach you a four-step self-check method to help operators quickly troubleshoot on-site. The pellet mill's reducer is the core power system. Power is supplied by the motor, and the torque is transmitted via the motor's output shaft to the reducer's input shaft, driving the internal gear set. Gear transmission reduces speed and increases torque, ultimately rotating the main shaft to complete the pelletizing process. Step 1 Shut down the machine and disconnect the power; safety comes first. Step 2: Loosen the motor's fixing screws and slowly lift the motor vertically. You will then be able to see the elastic coupling. Step 3: Remove the elastic element from the coupling and inspect it for cracks or damage. If any of the above abnormalities occur, the elastomer must be replaced immediately to prevent it from working while damaged and causing damage to other components. Step 4 : Check the motor shaft and couplings for any problems. If necessary, contact the manufacturer for assistance. If no obvious abnormalities are found after the above checks, the cause of the malfunction may lie within the reducer. It is recommended to contact the equipment manufacturer immediately for further diagnosis and repair by professional technicians. According to Yulong Company's product manual, the elastomer should be routinely replaced every 1,500 hours of operation to prevent abnormal noises or even transmission system failures caused by aging and wear. While troubleshooting is important, regular maintenance is the fundamental way to reduce repair costs. ?️ Yulong has been deeply involved in dense forming technology for 28 years, and has different solutions for many industries such as biomass energy, solid waste treatment, activated carbon, and lithium battery anode materials. ?
