Brief Introduction of ball mill. Ball mill is mainly used for grinding in mining (metallic minerals and nonmetallic minerals), cement, refractories, chemical, power plant, aluminum,building material, glass, ceramic, steel slag and fly ash, ect. It follows more crushing and less grinding principle to save energy.

This paper presents a solution for the detection and control of coal loads that is more accurate and convenient than those currently used. To date, no research has addressed the use of a grinding medium as the controlled parameter. To improve the accuracy of the coal load detection based on the kinetic energy of balls in a tubular ball mill, a Discrete Element Method (DEM) model for ball ...

Mill discharge temperature and differential pressure have a strong effect on efficiency and safety of a coal fired power plant. Therefore, it is imperative that they are closely monitored and controlled during mill operation to keep their levels within a predetermined safe and efficient operating range regardless of the rate at which the raw coal is fed to the mill.
