l>Ball mill as general-purpose grinding equipment is widely used in mineral dressing, building materials, chemical industry, etc. To make the ball mill operate well, and we must strictly abide by the procedures of operation and maintenance.
Before starting the ball mill, check whether the connecting bolt, gears, couplings are tightened. Check whether the oil of the oil tank and the reducer is in the adequacy, and whether the lubricating device and instrumentation have problems. Determine the flow of pipeline. Check whether there are ore to prevent the ball mill running. Check the ring gear and pinion gear case with or without abnormal noise.The order of starting ball mill is: first start the ball mill oil pump. When the oil pressure reaches 1.5 ~ 2.0 kg / cm2, it is allowed to start the ball mill, and then start the grading machine. All are functioning properly, and then start grinding.
In operation, we must always pay attention to bearing temperature. The temperature shall not exceed 50 ~ 65℃. We also always pay attention to motors, voltage, current, temperature, sound, etc. And pay attention to lubrication system. The temperature of the oil tank shall not exceed 35 ~ 40 ℃, the pressure to the pipeline should be maintained at 1.5 ~ 2.0 kg / cm2. Check the lubrication of transmission components such as gear, main bearing, and grade machine reducer. Constantly pay attention to the change of nature of ore, and take appropriate measures in a timely manner under the circumstances.
When stopping ball mill, first stop the feeder machine, then stop the ball mill machine until the ore has been dealt with. The last is pump. With grading machine screw lifting equipment raising sand surface, then stop grading machine.
