Grinding Mill an overview ScienceDirect Topics
This type of coal mill consists of a rotating tube (diameter 2-4 m, length 3-8 m) filled with 30–60 mm cast alloy balls. The drum is filled with balls to its 20%–35% of volume. In the past, most tube-ball mills had a single inlet and outlet, but now both ends are used to feed the raw material and also to remove the powdered product.

Millstone Wikipedia
Millstones or mill stones are stones used in gristmills, for grinding wheat or other grains. They are sometimes referred to as grindstones or grinding stones.. Millstones come in pairs: a stationary base with a convex rim
Ball mill media optimization Metcom Tech
mill grinding rate over the material’s grindability as measured in the lab. Mill percent solids optimization has thusly been achieved (McIvor et al., 2000). For media sizing, maximizing the mill grinding rate on a given ore is equivalent to maximizing the mill grinding efficiency. Ores of different grindability will be part of the discussion.
