How to Measure the Impact Forces in Ball Mills

Data from drop ball tests seem to be fairly well confirmed by in-mill tests with the hollow instrumented ball which, although heavier, is larger in diameter, less convex, softer steel, and strikes either the tumbling mass of ore and balls or descending mill liners. The ball was placed and recovered in the feed end of the mill where impact is

Mill (grinding) Wikipedia

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

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 particle-size measurement device and size-control cyclones.
