  • How to Charge Rods into a Rod Mill - The Charging Process ...

    Rods are loaded or charged into a Rod Mill using a mechanised charger. The rod charger with extendable boom moves rods safely inside the trommel/trunnion before charging with a typical 30 seconds or less cycle time per rod. How you charging a rod mill is best explained by the video below.

  • 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 ...

    A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

  • Mineral processing - Wikipedia

    Unit operations. Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the ...

  • Rod mills, how they function - Mine Engineer.Com

    Rod mills normally carry 35 to 65% rod charge by volume. The limits on charge level are (1) keeping the feed end trunnion open so that feed will get into the mill, and (2) keeping the rod charge low so rods will not work their way into discharge openings where they can cause rod tangling.
