Hammermill Crushers are known to generate material finer than 3/16" (4mm), which in some applications may be undesirable. However, if there is a market for finer material, or if it is acceptable within the desired product size, Hammermills can achieve reduction ratios that may otherwise require multiple crushers.

Roll Crusher Reduction Ratio. A great deal has been written, and said, about the limitations of the crushing rolls in the matter of reduction ratio, and there has been a tendency to pin the machine as a class down rather definitely to fixed maximums, regardless of any variables in conditions and characteristics of the materials to be crushed.

As mentioned earlier, the diameter to be adopted for the rolls is dependent upon the feed size and the nature of the material to be crushed. Since the reduction ratio for one pass of the material through a roll crusher is about 5–1, a higher reduction ratio may be obtained by putting the material through two crushers operating in series.
