    Electronic Sound Monitor - Jayashree

    The sound emitted from the Ball Mill varies in intensity as the quantity and average size of the material in the mill changes. This sound is caused by the grinding ball hitting the mill lining and the material in the mill. A high noise level indicates an under-loaded mill and a low noise level indicates an overloaded mill. Both these conditions
