  • Ball Mills vs Rod Mills

    When the mill is rotated without feed or with very fine feed the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of wedge shaped slots tapering toward the discharge end. The tumbling and rolling rods expend most of their crushing force on the Apr 09 2015 · Ball mill is a versatile grinding mill and has a wide range of applications. The mill can vary in size from small batch mills up to mills with outputs of hundreds of tons per hour. They are the most widely used of all mills. Roller mills.
