### Ball Mill: Operating principles, components, Uses

Ball mills grind material by impact and attrition The degree of milling in a ball mill is influenced by; Residence time of the material in the mill chamber The size, density and number of the balls The nature of the balls (hardness of the grinding material) Feed rate and feed level in Ball mills tumble iron or steel balls with the ore The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds The feed to ball mills (dry basis) is typically 75 vol% ore and 25% steel The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclonesBall Mill an overview ScienceDirect TopicsIn Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do Often, the ball used in ball mills is oversize “just in case” Well, this safety factor can Calculate and Select Ball Mill Ball Size for Optimum Grinding
