### Grinding Mill Design & Ball Mill Manufacturer

A closed circuit dry grinding system is very space consuming because of the classifier, the transport devices, the dedusting filter, etc. The feed to a dry grinding system must be dried if the moisture content is high. A ball mill is more sensitive to clogging than a rod mill. An air stream through the mill can reduce the moisture content and thus make a dry grinding possible in certain
