For a high energy loss and complex system of ball mill, this paper provide a ball mill load detection method based on genetic algorithm optimizing BP neural network. The effective frequency range of mill sound signal is analyzed. The soft measurement model of mill load based on mill sound signal is built. In order to solve the problem which converge slowly and easily reach minimal value, the
SOUND LEVEL METERS The primary tool for noise measurement is the Sound Level Meter (SLM). The compromises with sound level meters are between accuracy, features and cost. The precision of a meter is quantified by its type (see standards IEC, or ANSI for more details)

A free classroom noise level meter, monitor and management tool. Perfect if your school kids are too noisy! Bouncing balls react to sounds from the microphone.
Ball mill sound sensor is an intelligent grinding sound measuring instrument that can directly and effectively measure the load of the ball mill by receiving and analyzing sound level.
A STUDY OF GEAR NOISE AND VIBRATION M. #197;kerblom* and M. P#228;rssinen * CE Components AB, SE631 85 Eskilstuna. *Department of Machine Design, KTH, SE100 44 Stockholm. MWL, Department of Vehicle Engineering, KTH, SE100 44 Abstract The influence of gear finishing method and gear deviations on gearbox noise is investigated in this mainly experimental study.
Electronic Sound Monitor INTRODUCTION Ball Mills are the work horses of cement and minerals industry. The ball mills emit high pitch and low pitch sound depending on the material bed level in the grinding mill. Accurate measurement of filling levels and its communication in the form of a digital display helps utilize the ball mill more efficiently.
