Operation and maintenance of grinding ball mills

The working conditions of the grinder are rather poor, and incorrect operation or operational errors often result in an accident. Practice has proved that in strict accordance with the operation of the equipment operation, to ensure the normal operation of equipment and equipment to improve production capacity is very important.

Different structure and different specifications of  ball grinding mill, the rules will be different, but the basic principle is the same, the following for a brief introduction.

First, the preparatory work before the start
1) Carefully check whether the main parts of the mill is in good condition, fastening bolts and other connecting parts are loose, whether the transmission pieces meet or obstacles;
2) Check the auxiliary equipment such as belt system, electrical equipment and signal equipment is intact;
3) Check whether the debris inside the mill, if any debris, must be cleaned to ensure that the crusher in the no-load start;
4) Whether the lubrication part has oil;
5) Do the above preparatory work, the signal to boot to obtain the consent of the next process can only boot.

Second, the start and operation notes
1) After the start of the mill,going through a period of time reachs the normal operating speed, start the motor should pay attention to the ammeter on the console, usually after about 30s,start the peak current to normal operating current, in normal operation, but also pay attention to the ammeter indicating value, does not allow a longer time than the rated current value, or prone to burn the motor accident;
2) Behind the normal operation of the mill,you can start in front of the belt system;
3) Prevent large pieces of metal products and ore entering into the mill, the front of the process should be set in addition to debris devices;
4) When the electrical equipment after the automatic trip, if the cause is unknown, is strictly prohibited to force a continuous start;
5) In operation, the crusher should always check the lubrication point of the lubrication is good, and pay attention to the bearing temperature, under normal circumstances, the bearing temperature can not exceed 60 ℃, such as bearing temperature over 60 ℃, should immediately stop the inspection to find out Causes and take corresponding

Third, downtime precautions
1) The production process must be shut down, that is, first stop belt machine, and stop the mill when other materials crusher finished inside the mill.
2) Stop inspection, and do a good job cleaning.
