What is the cause of the intermittent current rise when the mill is running?

From the point of view of production practice, if the current indicated by the ammeter on the operating panel is found to be intermittently increasing periodically, the common reason is: when the various parts of the mill are operating normally, the mud head is required to be found. Looseness may occur, and the looseness of the scoop head is the main cause of the periodic intermittent rise of current. Of course, should check the bottom of the mud or other iron balls with a spoon is a spoon impede rotation mud.

If the current continues to rise and does not return to the rated current, it may be due to excessive mill load or low voltage. It is a kind of adjustment to the ore quantity caused by the large amount of ore, which is caused by mechanical problems and should be stopped. However, if the voltage is low, it is purely due to external power supply. The positive method is to observe whether there is any big change or motor temperature rise.
