  • Rod Mills Mineral Processing & Metallurgy

    End Peripheral discharge and center peripheral discharge rod mills are described in detail on pages 28 and 29. Feed and discharge heads of Rod Mills are conical in shape providing important advantages over a mill with straight heads. 1. They provide the essential feed pocket and also a space for the pulp to squeeze from the rod mass. This

  • Rod Mill Feed Size Grinding & Classification Circuits

    Rod mills have become niche comminution devices since about 30 years ago. Because of mechanical limitations on rod length and the need to have an aspect ratio for the mill that avoids tangling (a potentially deadly failure for those tasked with rectifying the problem) rod mills have a maximum installed power of about 2.5 MW. With SAG mills now

  • Rod mills, how they function Mine Engineer.Com

    Wet grinding rod mills are normally used in the mineral processing industry. Dry grinding is used in some areas; however, it is confronted with problems and should be avoided except where absolutely necessary. Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower

    Figure 8.2 Media motion in the tumbling mill. 8.1 Grinding 8.1.1 Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types rod, ball, pebble autogenous and semi-autogenous. The grinding action is induced by relative motion between the

  • Feed processing FutureBeef

    Feed processing usually means altering the physical (and sometimes chemical) nature of feed commodities to optimise utilisation by animals and to enhance mixing and stability of the diet. The major components of any diet, roughage and grain, are the feeds most likely to be processed. However, in some cases, the minor components of the diet (additives) are processed into pellets to help mixing

    F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.

  • Ball mill Wikipedia

    The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry.

    The rod mill discharge flows to a second classifier for desliming in the same manner as in the classifier after the scrubber. In case a finer grind is desired the rake product may be in closed circuit with the mill. Open circuit is usually satisfactory, since it does remove a big bulk of the load from the subsequent classification and thickening stages, and also provides a higher solids feed
