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

    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.

  • charging of rods in rod mills

    Rod mills, how they function. 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 Gypsum calcining,Gypsum calcining,ball mill their way into discharge openings where they can cause rod tangling.

    Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.

  • Recommended Rod Mill Bar Length

    Ever asked what size/length rods (bars) you need for charging your rod mill? It depends on the rod mill diameter itself. To prevent most conditions leading to rod charge tangling, the generally recommended relationship of rod length to mill diameter Inside liners is 1.4 to 1.6. When this ratio becomes less than 1.25 the risk of tangling Increases rapidly. For rod mills larger than 3.8 meters ...

    Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30% of the power used in a ball mill. When they are worn, rods must not stretch but break in rather small pieces, so that they can exit the mill. The energy consumed by rod mills could be ...

    ROD MILLS The grinding charge in a rod mill consists of straight steel rods with an initial diameter of 50-100 mm. The length of the rods is equal to the shell length inside the head linings minus about 150 mm. The rods are fed through the discharge trunnion opening. On bigger mills, which need heavy rods, the rod charging is made with a pneumatic or manual operated rod charging device. The ...

    An ore charge is added to the drum, and as it rotates, friction between the tumbling rods breaks the ore down into finer particles. Although similar in operation, a rod mill is often more effective than a ball mill as it requires lower rotational speeds and less steel to achieve the same results. It is, however, limited to maximum rod and drum lengths of approximately 20 feet (6 meters) and is ...
