Relationship between the charge of balls and electric machine current of coal mill in thermal power plants

Abstract

Abstract:

In order to determine the basis for charging steel balls for the ball mills in thermal power plants during the normal operation,ensure the relative stability of pulverizing capacity of ball mills, reduce pulverizing consumption per unit and optimize the combustion of boilers, the relationship between the charge of balls and current of ball mills is studied by experiments.The experimental data analysis determines the relationship between the mill current and the charge of steel ball, predicts the optimum charge of balls and puts forward the way and guidance of charging steel balls during operation of coal mill.

Key words:

thermal power plants;boiler, pulverizing system, steelball coal mill, charge, deep tapping of potential
