finding out the wear rate in ball mills calculations

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.

Speeds, Feeds, RPM and Depth Per Pass ...

PLUNGE RATE – This is the speed at which the bit enters the wood. Keep in mind that End Mills are meant to cut from the side whereas drills are meant to cut vertically. You can not plunge an end mill into material like you would a drill bit. For most woods, I usually set the Plunge Rate to 10 mm/sec or less.
