Ball Mill – GardenBallistics

A ball mill should be filled approximately a third to half full with grinding media, and that is equivalent to about 50 to 80 lead balls for my mill. The first thing I did was to mould some wet clay into two rectangular blocks. I then needed a ball pattern which I used a computer mouse ball – one of those old track ball
