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.

A ball mill is a type of grinder which consists of a cylinder. It is used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. The cylinder rotates around a horizontal axis.
