This should be compared with 4045% in wet grinding. The expression used for this phenomenon is that the charge in a dry grinding mill is swollen. Big dry grinding ball mills are often twocompartment mills, with big balls in the first compartment and small balls or cylpebs in the second one. An extra grate wall is used to separate the two charges.
