Ball Mill

Ball mills give a controlled final grind and produce flotation feed of a uniform size. 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%.

Ball Mill Application And Design

Ball mills scale up well and in fact improve in performed with increasing size. ball mills are available in sizes from laboratory scale (also called milling jars) of 0.1 usg to large 5,000 gallon mills. ball mills are available in various contact materials to accommodate contamination and wear.
