The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed …
Impact grinding is particularly effective for hard and brittle materials that easily brakes under force. The final particle size can be controlled by adjusting the speed of the impacting object and the design of the mill. Equipment such as hammer mills and ball mills utilize this principle for rapid and efficient size reduction.

A ball mill is a type of grinder that uses metal balls or other grinding mediums to reduce the size of various materials. The material to be ground is placed in a cylindrical container that spins on its axis. The metal balls or grinding media inside the container hits the material and breaks it down into smaller particles.
