3.5.2.2 Ball Mills. The ball mill accepts the SAG or AG mill product. 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. Get price

The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's crushing ratio is smaller. The feed size is usually between 20-30mm and the product size is 0-3mm. Feed Both the autogenous grinding mill and the ball mill feed parts are welded with groove and embedded inner wear-resistant lining plate.

Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach.
