In a roll crusher, material is fed from the top into a narrow gap (called the nip) between rotating cylindrical rolls, which grind the material to the desired particle size. 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 ...
