The ball mill is a very crucial grinding machine for the application in the mining production. Sometime, we may meet the sudden stop of the ball mill. At this time, we should calm down and carefully analyze the reasons about the sudden stop of the ball mill. At last, we should find out the ways to deal with the sudden stop of the ball mill.
The following reasons may cause the sudden stop of the ball mill.
First, the vibration of the main bearing exceeds the predetermined value, or the temperature of the main bearing exceeds 60℃.
Second, the failure of the cooling water system and lubrication system may cause the too high temperature of the lube oil.
Third, the material sieve tube may be seriously blocked so that the materials are discharged together with the scum.
Forth, the internal parts of the ball mill break off. The coupling bolts loose, break or fall off.
Fifth, the compartment plate is blocked, which may affect the normal production. There may be abnormal vibration, noise and temperature rise in the reducer and motor.
You can take the following measures to deal with the sudden stop of the ball mill.
First, after the ball mill stop grinding, you should immediately contact the professionally technical persons and stop the machine according to the required order.
Second, you should check the possible causes for the failure of the machine and exclude the failures accordingly.
You should pay much attention to the stop of the ball mill.
First, after the ball mill stops, in order to prevent the deformation of the cylinder, you can rotate the grinding body according to the intervals. Meanwhile, you can start the high-pressure oil pump to prevent the damage to the bearing bush.
Second, when the ball mill stops for a long time in winter, stop the cooling water after the temperature of the grinding body reduces to the same as the temperature of the environment. In addition, you can make full use of the compressed air to clean the storage water in the bearing bush.
