2020-5-2 Reduction Ratio Of Hammer Mill. For coarse reduction of grain, a roller mill may have a significant advantage perhaps as high as 85 percent over a hammermill in terms of throughputkwh of energy.For cereal grains processed to typical sizes 600 to 900 microns for the feed industry, the advantage is about 30 to 50 percent.

Optimum ratio between length L and diameter D, L:D is, usually, accepted in the range 1.56–1.64. The mill productivity also depends on many other factors: physical-chemical properties of feed material, filling of the mill by balls and their sizes, armor surface shape, speed of rotation, milling fineness and timely moving off of ground product.
