In the previous article, the reasons and solutions for the low output (or even no shaping) and excessive powder content in the pellets encountered by the straw pellet machine during the pelletizing process were discussed. It is believed that the vast majority of customer friends can independently troubleshoot and solve problems after reading the articles published by the editor.

This article still describes the troubleshooting and solutions during the operation of straw pellet machine, wood pellet machine, and biomass pellet machine. The abnormal noise and sudden stop problem points will be analyzed respectively.

I. Causes and Solutions of Abnormal Noise from Biomass Pellet Machines

(1)When hard foreign objects fall in or are mixed in the materials, the machine should be stopped immediately to remove the foreign objects.

(2) If the bearing is damaged and a "rattling" sound is heard, it is determined that the bearing is damaged and cannot be repaired. A bearing component of the same model needs to be replaced.

(3) Loose parts can also cause abnormal noises. At this point, stop the machine for inspection and tighten the components.

(4) The gear oil contains impurities and the gears are damaged. Due to the frequent gear breakage caused by the machine being stuck, the pellet machine cannot operate normally at this time. It is necessary to contact the pellet machine manufacturer to arrange for gear replacement.

(5) The elastic body of the main motor coupling is damaged. This clause refers to the pellet machines produced in previous years, as the vast majority of the 7th generation pellet machines and those produced earlier in previous years adopted couplings. The coupling component is damaged and needs to be replaced.

2. Reasons for the sudden shutdown of straw pellet machines and solutions

(1) Excessive load (even a blown fuse) can cause the pellet machine to stop suddenly. We suggest that in actual production, the gap between the pressure roller and the mold can be appropriately increased.

(2) Large foreign objects entered the granulation chamber, preventing the rotation of the pressure wheel. Just stop the machine and remove the foreign objects.

(3) Low voltage or small actual power of the motor. Here, the editor suggests that the power supply square number and material that meet the load requirements should be used.

(4) The oil pressure is too low. Check whether the oil suction filter is clogged, whether the oil temperature is too high, and whether there is any problem with the oil quality. The pressure gauge is faulty.

Basically, the editor has listed the common problem points and solutions encountered during the operation of the straw pellet machine. As long as you operate and maintain it in accordance with the regular procedures and keep a close eye on the raw material conditions, the pellet machine will continue to produce stably. If you still encounter problems that you can't solve, you can contact Tony directly and they will be resolved immediately.

Choosing a high-quality straw pellet machine manufacturer is a very important matter, as it can solve the vast majority of problems from pre-sale to after-sale.
