2013-4-24  IV. BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an L/D ratio of 1.5:1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground).

Fine Refining Ball Mill Royal Duyvis Wiener B.V.

Description. 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. The various layers of grinding elements move in the same
