The Study of Wear Matrix Model Test Improvement

摘要

The ball mills, which have great energy consumption, are commonly used in coal-fired power plant. The key to reduce their energy consumption is to determine the best ball loading, the optimum gradation and the complement parameters. The premise of determining these parameters is to give the balls wear law. The wear matrix model, which determines the balls probability distribution through their diameters, is one of the practice methods to determine the balls attrition rule. This study assessed the wear law through the change of balls weight, determines the program feasibility and the test time through the test of a ball mill.
