A discussion on the measurement of grinding media wear

The grinding media may be the ore itself (autogenous grinding), bars, balls, or cylpebs, or even the ore itself together with a small amount of balls (semiautogenous grinding) A survey found out that approximately 53% of the grinding circuits around the world use ball mills, and 38% use autogenous or semiautogenous grinding, and thereforeBall mills are equipments which has balls as grinding media and used for last step of grinding process There are many factors which effect grinding performance of ball mills like; liner design(PDF) INVESTIGATION OF EFFECTS OF GRINDING MEDIABauxite Lead – Zinc Rock phosphate Metal slag Coal There is no standard solution for mineral industry and wear rate of grinding media varies from mine to mine, ore to ore and even for the same ore time to time Different alloys are recommended depending on ore type and mill particulars in order to arrive at the most cost economic solutionGrinding Media Balls for Mines and Minerals Processing

Grinding Balls & Rods Mineral Processing & Metallurgy

Grinding Balls Steel balls ranging from ¾ to 5 in in diameter are used Rods range from 1½ to 4 in in diameter and should be 3 to 4 in shorter than the inside mill length Tube mills are usually fed balls smaller than 2 in, whereas 4 or 5in balls are more commonly used for ballmill grindingThe following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and millFactors Affecting Ball Mill Grinding EfficiencyFor an improved understanding, the wear rate constant is directly related to the grinding media consumption rate expressed in grams of steel per kWh drawn by the mill, using the simple expression: where dr represents the diameter of the new makeup balls periodically charged to the millEstimating Ball Consumption Molycop
