How to operate the ball mill correctly.

Newly mined ore shape is not the same, need to go through high-strength crushing, ball grinding machine grinding to get the required products, then how to correctly operate the ball mill, there are three main aspects: First, before starting note 1, before the ball mill start, should check whether there are people and debris around the equipment, check whether the screws are fastened, check the lubrication point of the oil is proper, check the tape transport machine, the machine is normal.
2, check whether the oil in the tank and decelerator is sufficient, check the entire lubrication device and instrument is not faulty, whether the pipe is clear, if there is a blockage, to be timely dredging.
3, the first test run or long-term stop grinding after starting again, should first put a small amount of lubricant on the hollow bearings at both ends, and use artificial disk grinding for a week, to confirm that there are no abnormalities, and before and after the relevant jobs to get in touch, get allowed to start the signal before starting.
II, the operation of note 1, ball mill in the first 5 minutes of operation to focus on monitoring motor current fluctuations, including observation of normal operating state current values, to ensure that the equipment is free of abnormal current fluctuations and other phenomena, to achieve normal operation after the gradual feeding.
2, in production should be based on the nature of ore and to the grain size of the ore, timely adjustment of the ball mill to the amount of ore, grinding concentration and sand return amount of the size, to ensure that the graded roll-over fineness to meet the requirements of the mineral process, for the selection of operations to create good conditions.
3, ball mill in the course of operation to maintain a smooth, no strong vibration, abnormal noise, etc. , pay attention to observe the reducer, motor, connection plate, as well as all joint bolts, foot bolts and cylinder lining bolts, such as loose, off, the motor and its control system is working properly, if found that the components are not working properly, it is necessary to stop in time to check and adjust.
3. Precautions 1 when stopping, the ball mill shutdown order is to stop the feeder, the main motor, when the ball mill stops turning, stop the low-pressure oil pump, according to the bearing temperature stop the high-pressure oil pump, every 30 minutes open 2 minutes high-pressure oil pump, until the cylinder body cools to room temperature.
2, when the ball mill needs a long-term shutdown, should first open the lubrication system to make the main bearing float, and then use the carrier and hydraulic jack system top grinder, so that the hollow shaft away from the shaft tile, and then apply a palletizing support mill barrel body.
then cut off the ball mill and auxiliary equipment, drain the oil from the housing and drain the water from the cooling tube to prevent it from freezing and cracking when it is cold.
