I. Pre-Replacement Preparation
1. Shutdown and Safety Measures
Turn off the ball mill power, lock the control cabinet, and hang a warning sign.
After the equipment has completely stopped, wait for the bearing temperature to drop below 50°C.
2. Tool and Material Preparation
Prepare new lubricant (the type must comply with the equipment manual).
Prepare an oil drum, oil filter, cleaning cloth, wrench, and other tools.
II. Draining the Old Oil
1. Draining the Old Oil
Place an oil container under the oil drain port of the bearing housing. Slowly tighten the drain bolt to avoid oil splashing (wear protective gloves when handling hot oil).
2. Removing Residual Oil
After draining the oil, tilt the machine for 15 minutes to ensure that any residual oil in the oil circuit is drained.
Inspect the condition of the old oil: If metal particles or emulsification are present, shorten the oil change interval.
III. New Oil Filling Procedure
1. Lubrication System Cleaning
Flush the bearings with kerosene Remove metal debris from the inside of the seat.
Replace or clean the oil filter (if washable).
2. Filling with New Oil: Slowly pour new oil through the oil filler port to the center line of the dipstick. The recommended initial filling volume is 80% of the rated capacity, and top up after operation.
3. Seal Inspection: After tightening the oil drain bolt, start the equipment and run it at no load for 10 minutes. Check all sealing surfaces for leaks and ensure the oil level is stable.
IV. Precautions
1. Oil Change Interval: Under normal operating conditions, change oil every 2000 hours. In dusty or high-temperature environments, reduce this to 1500 hours.
2. Waste Oil Disposal: Waste oil must be collected in a dedicated container and must not be discharged directly. It can be filtered and used to lubricate secondary equipment.
3. Special Operating Conditions: Preheat the lubricating oil to above 20°C during winter oil changes. In high-humidity environments, enhance oil moisture protection measures.
