oct 08, 2019 3.3 rod mill. the rod mill is developed on the basis of the ball mill. It has the advantages of reliable processing technology, low investment, less auxiliary equipment and simple process flow. It can be combined with the ball mill to form a different grinding process. the rod mill mainly grinds the ore by the pressure and the grinding force of ball mills of greater length are termed tube mills, and when hard pebbles rather than steel balls are used for the grinding media, the mills are known as pebble mills. In general, ball mills can be operated either wet or dry and are capable of producing products on the order of 100 um.
