We have analytically derived a mathematical model of energy-saving ore grinding by a ball mill with a three-phase motion of grinding bodies, invariant to a change in the length of rods during wear. The model can estimate the energy efficiency of grinding larger pieces of ore based on the resulting volume of crushed large-lump material. The grinding bodies may be flint pebbles, steel balls, metal rods lying parallel to the axis of the drum, or simply larger pieces of the material itself. In hammer mills, driven swinging hammers reduce the material by sudden impacts. See Crushing and pulverizing, Pebble mill, Tumbling mill

Even in a Mixer Mill, which generally uses less grinding media and therefore creates less friction than a planetary mill, temperatures exceeding 100 C are not unusual. When using spherical media in a ball mill, the only way to reduce friction is to reduce the number of pieces of media however, this in turn reduces the efficiency of grinding. Description of the Rice Huller and Grinder. Figure 1 shows the final design of the Rice Huller and Grinder. It is 23.5 inches long, 21 inches wide and 43 inches tall. The machine consists of main parts like the feeding hopper, roller, sieve, knife, vacuum, plate grinder, screw conveyor, pulley and transmission belt, electric motor.
