ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. according to the need of customers, ball mill can be either wet or dry designs. ball mills have been designed in standard sizes of the final products between 0.074 mm and 0.4 mm in cement ball mill structure. when ball mill is working, raw material enters the mill cylinder through the hollow shaft of the feed. the inside of the cylinder is filled with grinding media of various diameters when the cylinder rotates around the horizontal axis at a certain speed, under the action of centrifugal force and friction force, the medium and the ball mills are generally used to grind material inch and finer, down to the particle size of to microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.
vertical roller mills Vs ball mills has long been a raging debate in the cement industry. In spite of the fact that vertical roller mills have been around for over ten years now and have gradually become the standard as far as cement manufacturing goes, several cement manufacturers still prefer ball mills for cement production when they want to design new grinding plants or a new integrated gui the PM 100 planetary ball mill is a benchtop unit designed to pulverize soft, fibrous and brittle materials. the mill develops extremely high centrifugal forces resulting in energy input that is up to 50% higher than in other planetary ball mills.
