2008-9-15  Ball mill load is the most important parameter optimized in the Ball Mill Pulverizing System (BMPS) in Thermal Power Plant. The accurate measurement of ball mill load is imperative and difficult. The approach based on self-adaptive feature extraction algorithm for noise signal and LS-SVM model is proposed to achieve this purpose.

#### Ball Mills an overview ScienceDirect Topics

The ball mill is a cylindrical drum (or cylindrical conical) turning around its horizontal axis. It is partially filled with grinding bodies: cast iron or steel balls, or even flint (silica) or porcelain bearings. Spaces between balls or bearings are occupied by the load to be milled. Following drum rotation, balls or bearings rise by rolling
