You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell C-model or equation to get the RPM that corresponds to 75% for that mill diameter.

When a ball-nose tool is used, smooth finish requirements may call for coolant's use. Here, the coolant serves as a lubricant. The problem with a ball-nose tool is that the tip of the tool has no surface speed. When a typical ball-nose tool takes very light finishing cuts, material can become trapped in the "web" design in this low-speed region.
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a …
