type of mill is much shorter than that in tube (ball) mill; therefore, the crushing process and mixing process became more harmonized and this contributes to quality control. (3) The installation space is smaller and this leads to lower noise level. (4) This type of mill can crush materials which are too large to be fed into the tube (ball) mill.
