Abstract In fine grinding of cement in a ball mill, it is sometimes impractical to grind finer in a dry state. Even though the chemical reactivity requires the material to be dry ground, it is sometimes necessary to use different breakage machines to ob tain the product, but it is usually more expensive, requires more energy and reduces capacity.

Ball mill is a slow process. The soft, tacky, fibrous material cannot be milled by a ball mill. These materials may cause problems by caking on the sides of the mill; Wear occurs from the balls and the inside surface of the cylinder hence there is a possibility of contamination of the product with mill material.
