Empty test run of ball mill reduces mechanical failure
How to improve the safe operation rate of the ball mill machine? The empty car test run is a good measure. The specific process of the ball mill is: After the ball mill is installed, the empty car test run can be performed after passing the test. The test run of the ball mill should be skillful. The ball mill operator is responsible for carrying out and strictly observing the safety operation rules of the ball mill. (1) The continuous operation time of air operation shall be no less than 12-24 hours. Problems found during operation shall be promptly resolved. (2) The air-running test machine can carry out the load test run normally, and the load test run should be carried out in stages. During the load operation, feeding should be performed according to the discharge conditions to avoid unnecessary wear and damage to the steel ball and the cylinder liner. 1. Add the appropriate material and 1/3 amount of steel balls (see ball mill general drawing for the maximum ball load) to run for 12-24 hours. 2. Add 2/3 of the steel balls for 24-48 hours. 3. According to the ball mill discharge condition, the output of qualified products shall be determined with reference to the actual ball loading of the ball mill of the same concentrator, determine the reasonable ball loading of the ball mill, and conduct a test run of not less than 72 hours. (3) The increase in the above-mentioned load and the length of the test run shall be determined on the basis of the running-in conditions (temperature rise, noise, tooth surface contact, etc.) of the gears and reducer gears. Before the tooth surface contact accuracy reaches the design requirements, it must not be operated at full load. (4) The cooling and lubrication system shall be operating normally during the test run. The temperature of the main bearings, transmission bearings, and reducer shall be normal. (5) After loading 2/3 of the number of steel balls for 24-48 hours, all bolts shall be checked and tightened again. (6) The commissioning work should do a good job of various records. The ball mill is mainly used for the mixing and grinding of ceramic raw materials. It is necessary equipment for producing various types of ceramic products. The machine uses self-coupling decompression to start and reduces the starting current. Its structure is pided into integral type and independent type. It adopts V-belt drive, single-stage or double-stage deceleration, equipped with independent low-power motor for loading and unloading.
