Bearing Maintenance of Double Roller Press Granulators

Bearings are core transmission components of organic fertilizer equipment. Proper maintenance reduces abnormal noises and jamming, extends service life, and ensures stable operation of the double roller press granulator. Daily basic lubrication is crucial. Strictly adhere to the recommended cycle for adding high-temperature resistant grease. Before daily operation, check the oil levels in the bearings of the pressure roller shaft, main shaft, and transmission seat. Replenish grease promptly if necessary. Dry running is strictly prohibited to avoid high-temperature wear and seizing. The amount of grease added should be moderate; too much can cause overheating and oil leakage, while too little will not provide adequate protection. Evenly fill the bearing gaps. Proper sealing is essential to prevent impurities. Regularly inspect the bearing end covers, seals, and dust covers. Replace any worn or damaged parts immediately. During production, dust and damp materials can easily enter the cavity, damaging the ball bearing tracks. A good seal effectively prevents contaminants from entering, reducing the probability of corrosion and wear. Proper start-up, shutdown, and load operation are crucial. Forcibly starting the equipment with material or overloading the extrusion process is prohibited, as sudden stress will exacerbate bearing impact damage. During operation, pay attention to machine vibration, abnormal noise, and abnormal temperature. If the bearings become hot or the noise increases, stop the machine for troubleshooting. Do not continue production with defects. Regularly disassemble, inspect, and maintain the machine. Monthly stop the machine to check bearing clearance and rotation smoothness. Adjust any jamming or loosening promptly. Replace worn, rusted, or excessively clearanceed parts immediately, and clean accumulated dust and residue from inside the bearing housing. Tighten the bearing housing fixing bolts to prevent uneven stress caused by operational misalignment. Properly protect the environment and ensure proper shutdown protection. Minimize dust accumulation in the workshop and prevent long-term moisture corrosion of metal parts. For long-term shutdowns, evacuate the equipment of materials, apply protective grease to the bearings to seal them, prevent rust and jamming, and maintain the bearings in good operating condition from all aspects.
