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 particle-size measurement device and size-control cyclones.

End mills are multi-fluted cutters that are commonly used in machining. These tools are vertically mounted and have two or more helical flutes. Their basic shape is to cut on both ends and sides of a work piece. A common type is the square-end mill, which has no finish on the tip. Radius-tipped end mills are those that have a straight cutting
