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.

Therefore, dry grinding in a jet mill is the best method, with the material then requiring blending into a wet dispersion. The end material must be dry, and the size goal is 500 nanometers (very small). In this case, a wet media mill must be used, and the material needs to be dried after particle size reduction.

In continuous wet ball mills, the composition of feed (hard ore or soft ore) to the mill varies continuously, leading to uncontrolled grinding in the mill. In view of this, a new design of the discharge mechanism has been implemented to remove the ground particles of desired particle size fraction with minimum recirculating load (+150 µm).
