Get Priceintroduction. grinding operation is used extensively in the industry of beneficiation, metallurgy, chemical engineering, and electric power. assisted by the impact and abrasion between media and ore, the grinding operation reduces the particle size in the mill .to produce the qualified size and high liberation of granule for the subsequent ball mill size as a replacement. grinding media wears and reduces in size at a rate dependent on the surface hardness, density and composition of the ore. ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter. other factors include: speed of mill rotation; mill diameter; mineral density;there are three types of grinding media that are commonly used in ball mills: steel and other metal balls; metal cylindrical bodies called cylpebs; ceramic balls with regular or high density. steel and other metal balls are the most frequently used grinding media with sizes of the balls ranging from to 150 mm in diameter 30.sep 01, 2013 grinding circuit simulation combined with ball weal law was used to determine the optimum composition of the make-up ball sizes in tumbling ball mills. It was found that the optimum composition depends on various factors, including the feed size, the product size, the mill diameter and the breakage parameters.
