The principles of grinding are well established: the pre-ground liquor is pumped through the ball mill's grinding vessel in one or more stages. The refining action is accomplished by a special shaft with agitator arms and diverters rotating in a vertical jacketed grinding tank, which is filled with hardened steel balls.
