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.
