What to Do If Damp Fuel Pellets Cause Wood chip pellet machine Blockage?

Dec 25, 2025

First and foremost, when encountering a blockage, the first priority must be safe operation to avoid accidents and equipment damage. Immediately stop feeding, turn off the motor power of the biomass wood pellet mill, unplug the main power cord, and wait for the equipment to completely stop running (at least 5 minutes). It is strictly forbidden to clean the blockage by hand or with tools while the equipment is running, nor should you force the machine on to try to clear the blockage, as this will overload and burn out the motor, and may even make the blockage tighter.

Second step: Clean the blockage in sections, first the feed inlet, then the pressing chamber. Cleaning the feed inlet: Use a wooden or plastic shovel (avoid using metal tools to prevent scratching the wood pellet manufacturing equipment) to remove the clumps of damp particles from the feed inlet. Be careful not to use excessive force to prevent material from falling deep into the pressing chamber. If the feed auger is stuck with particles, manually rotate the auger shaft with a wrench to slowly clear the stuck particles. After cleaning, push the auger shaft to ensure it rotates freely. Cleaning the Pressing Chamber: Open the inspection door of the pressing chamber and use specialized cleaning tools (such as steel chisels and brushes) to thoroughly clean away any clumps of particles and material clogging the die holes. When cleaning the die holes, clean in the direction of the holes to avoid damaging the inner walls. After cleaning, wipe the surface of the pressure rollers and die with a clean cloth to ensure there is no residual damp material.

Step 3: Inspect Equipment Components and Test Run After Confirming No Damage. After cleaning the blockages, check the wear of the pressure rollers and die for scratches or deformation caused by blockages. Inspect the feeding screw and transmission system to ensure they are not loose or damaged. Add a small amount of grease to the pressure roller bearings to prevent insufficient lubrication caused by contact during cleaning. During the test run, first run the machine unloaded for 3-5 minutes to observe whether the equipment operates smoothly and without abnormal noise. Then, feed a small amount of dry fuel pellets at a low speed and observe whether the pellets form normally and whether there are any signs of blockage. If there are no problems, resume normal production.

Finally, here are three tips to avoid clogging your Biomass Sawdust Pellet Machine again: 1. Strictly check the moisture content of the pellets before feeding; dry any damp pellets before use. 2. Install a metal filter at the feed inlet of the wood pellet machine to intercept clumped damp pellets. 3. Adjust the feed speed to maintain a uniform, low-speed feed, preventing damp pellets from accumulating inside the machine. If you frequently encounter damp pellet problems, it is recommended to take moisture-proof measures during storage to reduce the generation of damp pellets at the source.
