Ball Ball Mill Design And Operation Procedure

The operating principle of the ball mill

· The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed ...

Ball mill

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about

Rod mills, how they function

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed. Rod mills usually require greater operator attention. It ...

Ball Mills

Cylindrical Ball Mills differ usually in steel drum design (Fig. ), which is lined inside by armor slabs that have dissimilar sizes and form a rough inside surface. Due to such juts, the impact force of falling balls is strengthened. The initial material is fed into the mill by a screw feeder loed in a hollow trunnion; the ground product is discharged through the opposite hollow ...

Ball Mill

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 cyclones. The ...

Optimizing your SAG mill operation

· The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal. In addition, operating mills at ...
