122· 1. Introduction. Grinding operation is used extensively in the industry of beneficiation, metallurgy, chemical engineering, and electric power. Assisted by the impact and abrasion between media (steel ball, steel rod, gravel, ceramic ball) and ore, the grinding operation reduces the particle size in the mill [[1], [2], [3]].To produce the Consumption of steel grinding media in mills A review,201381· The consumption of grinding media has been studied extensively in the mineral process industries, where steel balls and rods are mostly used to reduce rock fragments and ore particles to the fine sizes required for mineral liberation and further downstream processing.
