Ball mill are used in the mining, cement, chemical and agricultural industries, particularly tumbling ball mills [1–4]. The comminution process is dependent on the rotation of the mill to lift the grinding media for reducing particle size, including abrasion, crushing and impacting. Due to the impact load behavior between charge and lifter direct impact of milling efficiency, the efficient ...

 · A data set derived from 50 experiments on the wear rate of a low alloy steel ball was applied in this work. The experimental data were obtained from literature [].The experimental conditions, influential factors and the total wear rate for each experiment, which was determined by the grinding media weight loss, are implied in Table measure the grinding media mass losses through total wear ...

 · The linear (or superficial) theory of wear, in turn, considers that most comminution events occur due to the abrasion mechanism ballparticleball; in this case, the wear rate should be proportional to the surface of the ball, that is, to the square of the diameter. This is the most widely accepted theory at present to characterize the constant yet slow consumption of grinding media in rotary ...

Thousands of tons of grinding media are consumed in phosphate chemical plants every year, and reduced wear and corrosion rates will significantly reduce the grinding costs and improve the grinding efficiency by maintaining optimal grinding ball size. Previous efforts to reduce grinding media consumption were mainly on finding the most wearresistant metal,, highchromium alloys, and sig
