Ball Mill We bring forth a highly advanced Ball Mill, specifically engineered for both wet as well as dry cement grinding applications Classified depending on the circuit design, bearing, grinding type and drive, the selection is made on the basis of the product fineness, quality, and nature of raw material, site conditions and specific requirements

Definition of closed-circuit grinding A size-reduction process in which the ground material is removed either by screening or by a classifier, the oversize being returned to the grinding unit Typical examples are a dry pan with screens, dry milling in an air-swept ball mill, and wet milling in a ball mill ,

If P is less than 80% passing 70 microns, power consumption will be Ball Mill Power Calculation Example A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work .

Grinding of cement clinker has been traditionally performed by the ball mills which can either be open circuit or closed circuit with an air classifier Selection of right mill for the specified duty is the most critical for circuit design, since it has the highest capital and operating costs
