Introduction

IDM/M Series Mill Sound Meter is used for judging filling rate and grinding status in the mill by testing decibel value of mill operation, thus optimizing mill production. It is widely used for test of ball mill during production in building material, metallurgy, chemical industries, etc., which is conductive to improve mill output, decrease power consumption and reduce labor intensity.
