Roll crushers can be configured with one, two or three pairs of rolls, depending on the application. Compared to hammermills, roll crushers can produce a more uniform grind at a much lower operational cost but cannot attain as fine a grind. Figure 3 shows a sieve analysis for a grind from a hammermill and a roll crusher.
