If the mill is used as a crusher, which means that the particle size diameter of the finished product is quite coarse (>> 1 mm), then the mill can be discharged by gravity. However, for finer target sizes, requiring very high speed and thus moving a lot of air, the final product can be transferred pneumatically.
