The operator must be familiar with the general structure and performance of the equipment. The sum of the volume of parts and abrasives shall not exceed 90% of the hopper volume. After switching on the power supply, empty operation should be carried out, and the operation should be stable without abnormal noise. Otherwise, stop the machine for inspection. Before grinding, the workpiece must be deoiled and decontaminated. The abrasive agent and the amount of water must be added timely according to the grinding condition of the workpiece. After the work is finished, cut off the power supply, clean the equipment, and do a good job of equipment maintenance. Before starting, check the fastening screws, check whether the motor shaft rotation is flexible. When the equipment is in operation, it should stop immediately if any abnormality is found. Every 6 months, the bearing oil injection port of the vibration motor or the rotating shaft should be filled with lithium base grease. After work, should cut off the power supply.
Empty load test run. Main engine and analysts are steering correctly. The empty load test of the main engine should take no less than 1h according to the steering requirements. When the main engine is running under empty load, the roller device should be tied with steel wire rope to avoid the contact between the roller and the grinding ring. If it is unconditional, the roller device can also be removed. The empty load test run of the main engine should be stable, and the highest temperature of lubricating oil should not exceed 800c. The temperature rise shall not exceed 400c. The bevel gears of the analysis machine should run smoothly, without abnormal sound, and ensure smooth oil circuit. The blower should observe the rotation direction, there should be no abnormal sound and vibration, the maximum temperature of the rolling bearing shall not exceed 700c, and the temperature rise shall not exceed 350c. Meet the test run. The test can be carried out only when the parts can work normally as proved by the empty load test. The test run time shall not be less than 8h (hours). The mill should work normally, and the transmission part should not have abnormal sound and shock vibration. The maximum temperature of rolling bearings and lubricating oil shall not exceed 800c, and the temperature rise shall not exceed 400c. There should be no air leakage in the contact of each flange in the piping device. The output of grinding powder reaches the specified target. Adjust the speed of the analyzer to control the particle size of the finished product within the range of 0.44-0.125mm. After the operation is qualified by air load and load, the fasteners are tightened again and can be put into normal operation.
