— are from 8 to 52 inches. Longer rolls provide greater grinding capacity. The more roll pairs the mill has, the greater the size reduction it can achieve. The rolls typically have a cast-iron core with a 5⁄ 8- to 3⁄ 4-inch-thick outer layer made of alloy steel. The outer layer's surface is typically corrugated with grooves or
The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out. Grinding is always carried out under wet conditions, with about 70% solid mixture in water. This procedure maximizes ore production and minimizes power consumption.
This type of mill is used for dry grinding only and accepts only relatively soft materials. Small machines can have a throughput of only a few tens of kg per hour whereas larger machines are capable of handling up to 40 or 50 tons per hour and occasionally more. Feed size varies according to the machine.
