Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...
Water Spray in Cement Mills. Water spray installed generally in second compartment of ball mill to control cement temperature. Cement discharge temperature should be kept below about 110 o C but, the same time should allow some 60% dehydration of gypsum to optimize cement strength without excessive false set.
