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 Grinding and Mill Cooling. PROBLEM. Insufficient mill cooling lead to material agglomeration on balls and liners. The grinding is not any more done by balls against material but by material against material. SOLUTION. Adapted mill cooling, playing with:-Clinker temperature-Mill ventilation-Water injection
