Ball mill operation and maintenance

ball mill operation and maintenance

To make the ball mill operate good, we must strictly abide by the operation and maintenance procedures.

Before starting the ball mill, check whether the connecting bolt, gears, couplings are tightening;

Check whether the oil of the oil tank and the reducer is in the adequacy, and Whether the lubricating device and instrumentation have problems. Determines the flow of pipeline. Check whether there are ore to prevent the ball mill machine running. Check the ring gear and pinion gear case with or without abnormal noise.

The order start machine is:First start the ball mill oil pump. When the oil pressure reach 1.5 ~ 2.0 kg / cm2, it is allowed to start the ball mill, and then start the grading machine. All are functioning properly, 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, grading machine reducer. Constantly pay attention to the change of nature of ore, and to 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 to raise sand surface, and then stop grading machine.

The ball mill is horizontal cylindrical rotation device, driven by brim gearwheel. There are two chambers and grids. Material goes into the first chamber through the feeding inlet. Inside the first chamber, there are stage liners and ripple liners as well as steel balls. The shell rotates so as to generate centrifugal force, and this force brings ball to a certain height and then balls drop down by gravity, the impact is the grinding force to the material. After the primary grinding, materials go into the second chamber through segregate screen. In the second chamber, there are flat liners and steel ball. After the secondary grinding, material is discharged from the discharging mouth. Then the whole grinding process is ended.

SBM is a famous ball mill manufacturer in China, design and manufactur ball mill for wet and dry grinding applications.
