Understanding the mechanism: How does a ball mill work?

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, and ceramics. It works on the principle of impact and friction between rotating balls and the powder materials. The ball mill consists of a rotating drum and a hollow cylinder filled with grinding media, typically ...

Measurement of Steel Ball Impacts Inside a SAG Mill

How is the steel ball impact detection and counting done? The impact meters use microphones that are installed outside the mill in the charge toe zone. These microphones acquire the sound signal, which is processed in real time to detect the noise pattern generated by the metal-metal impact of a ball against the liners or against other balls.
