A further advantage of this grinding system is the very low noise emission which permits the use of far less extensive sound attenuation measures than are necessary in ball mill plants
The sound emitted from the Ball Mill varies in intensity as the quantity and average sie 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 underloaded mill and a low noise level indicates an overloaded mill
