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.

· What I posted IS correct and the only shape a ball end mill will make when programmed to do a right angle path. Why the other program that JD used did not show the correct path makes me think that even though he swept what looks to be a 3d profile I believe the program is still taking a 2d shape from that 3d "tool" and sweeping it identical to how Inventor does it.

A secondary mill will require the high surface contact with more of the grinding motion that the lower cascade brings. This means that the secondary mill will have LOW PROFILE ROD MILL LINERS in them. If it is a ball mill being used as the primary grind the size of the grinding media will be increased, this is to increase their impact.
