Tips and Troubleshooting for Wet-Process Stirring Tooth Granulators
Wet-process stirring tooth granulators are favored by small and medium-sized organic fertilizer plants due to their high pelleting rate and adaptability to high-moisture raw materials. To achieve optimal equipment performance, the material moisture content should be controlled between 20% and 40%, and the raw material should be ground to a moderate fineness to prevent large impurities from entering the machine and causing blockages. Start the machine under no-load conditions, then feed the material evenly. Overloading is strictly prohibited to prevent motor overload and stirring tooth deformation.
During daily use, regularly check the wear-resistant liners and alloy stirring teeth for wear. Replace worn parts promptly to prevent material from sticking to the walls and reducing the pelleting rate. Keep the equipment clean. Clean up any residual material after each shutdown to prevent hardening and affecting future use. Regularly lubricate the transmission bearings and reducer to ensure smooth operation.
Common faults of stirring tooth granulators include low pelleting rate, material sticking to the walls, and abnormal vibration and noise from the equipment. Low pelletizing rate is mostly due to material moisture imbalance or worn agitator teeth. Adjusting the humidity or replacing the agitator teeth will solve the problem. For sticking to the wall, check the integrity of the liner, clean up the accumulated material, and reduce the feed speed. Machine vibration is mostly caused by loose anchor bolts or misaligned transmission components. Tightening and leveling will restore stability. Mastering usage and maintenance techniques can significantly reduce the failure rate and ensure long-term stable and high-yield operation of the equipment.
