WhatsApp: +86 18838072829A Ball Mill is a type grinder that blends or grinds materials for various applications. Impact force enables size reduction in feed material. The cylindrical shell rotates around its horizontal axis. The main element enabling grinding are the hard and small balls in the ball mill. These balls are usually made of steel.
WhatsApp: +86 18838072829This 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.
