1. Optimize Operation and Management
1. Feed Control
Strictly limit feed particle size (generally ≤25mm) and moisture content to prevent overly wet materials from adhering to the drum wall or clogging the baffle plates.
Install a magnetic separator to remove metal impurities and reduce impact wear on the liner and steel balls.
2. Load and Speed
Avoid prolonged no-load operation (≤30 minutes) to prevent ineffective wear of the steel balls and liner.
Maintain a stable voltage (380±5V) to prevent abnormal motor overheating or transmission system imbalance.
2. Enhance Lubrication and Cooling
1. Lubrication System Maintenance
Use high-temperature-resistant lubricant (such as No. 90 anti-wear gear oil) for the main bearings and gearbox. The oil level should be 4-6cm below the gears. Test the oil quality every three months.
Install temperature sensors to monitor bearing temperatures in real time. If the temperature exceeds 60°C, shut down the machine for inspection.
2. Cooling and Cleaning
Regularly clean the oil cooler and oil filter to prevent oil blockage and lubrication failure. During winter shutdowns, drain the cooling water pipes to prevent freezing and cracking.
III. Maintenance of Key Components
1. Liner and Steel Balls
Replace the liner when it is worn to 2/3 of its original thickness. During installation, ensure a tight fit and even tightening of the bolts.
Replenish the steel balls regularly, maintaining a filling volume of 25%-30% of the cylinder volume and adjusting the gradation according to the hardness of the material.
2. Transmission System
Check the gear meshing clearance. Replace any teeth with wear exceeding 20% or broken teeth.
Damaged coupling pins should be promptly replaced to prevent transmission imbalance.
IV. Preventive Maintenance and Intelligent Monitoring
1. Regular Inspection
Minor Repair (1-3 months): Clean the bearings, change the lubricant, and tighten any loose bolts.
Major Repair (2-5 years): Completely disassemble and inspect the cylinder, replace the main bearings and worn gears, and restore equipment accuracy. 2. Intelligent Monitoring
A vibration analyzer monitors the cylinder vibration spectrum, and an ultrasonic thickness gauge tracks liner wear rate.
A wear database is established to predict replacement cycles for wearing parts and reduce unplanned downtime.
5. Maintenance During Long-Term Downtime
Clean residual material from the cylinder and apply anti-rust oil to exposed metal surfaces.
Check cylinder levelness, adjust V-belt tension, and lubricate the screw.
