Abstract: Ball mill is widely used in metallurgical mining industry, grinding operation of power consumption and metal consumption is large, how to effectively reduce energy consumption and metal consumption is an important research content. This paper reviews the improvement of mill structure, the technology of precise ball make-up and the preparation of wear-resistant materials. The improvement of mill structure mainly includes the following measures: the ball mill should be enlarged, the edge drive should be changed to the center drive, the sliding bearing should be changed to the rolling bearing, and the grinding medium and lining plate types and shapes should be improved. Accurate ball make-up technology has been widely used in mines in China, which has reduced the power consumption and ball consumption of ball mills to varying degrees wear-resisting material preparation technology centered manganese steel material, cast iron, alloy steel materials, double metal composite materials, magnetic materials, rubber materials design and preparation, mainly through the design of micro alloying and heat treatment system improvement to achieve the purpose of refine grain, change organization, improve the wear resistance of materials, so as to reduce the wear rate.
