Mill (grinding) - Wikipedia

Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency . Autogenous mill. Autogenous or autogenic mills are so-called due to the self-grinding of the ore: a rotating ...

It will also be understood that as the grinding process progresses the shape of at least some of the rod-shaped particles will evolve such that the ends round off (for example, as shown in FIG. 4), and the aspect ratio lowers, and in some cases the virgin rod-shaped particles may eventually become small spheres, so a typical mature grinder may contain rods, worn rods and even spheres. Thus, a ...

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 ...

Because grinding theories are imperfect and ore hardness can vary with size, grindability tests are designed to best represent the size reduction of the industrial equipment analysed.
