I Ball mill maintenance - Fathom Engineering

As the ball mill rotates, the steel balls in the cylinder rise up on the mill's inside surface and eventually tumble down to the bottom. The raw material is fed into the ball mill at the ends and the steel balls impacting together eventually grind the material into a powder, which is collected through slots at the centre of the mill.
