A ball mill is simply a container that is filled with pebbles (either of porcelain or stones Flint) into which a charge (powder or slurry) is put and that is then mechanically rotated to cause the tumbling pebbles to crush particles that happen between them. Ball mills can be continuous or periodic, they can be small or gigantic, lowspeed ...
