  • Ball Mill an overview | ScienceDirect Topics

    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 cyclonesIn ball mills, steel balls or hard pebbles to break particle based on impact and attrition A rotating mill charged with media and ore is lifted against the inside perimeter Some of the media falls and impacts the ore particles at the bottom of the millAMIT 135: Lesson 7 Ball Mills & Circuits – Mining MillBall mills are filled up to 40% with steel balls (with 30–80 mm diameter), which effectively grind the ore The material that is to be ground fills the voids between the balls The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fractureBall Mills an overview | ScienceDirect Topics
