Roll crushers are arbitrarily divided into light and heavy duty crushers. The diameters of the light duty crushers vary between 228 and 760 mm with face lengths between 250 and 460 mm. The spring pressure for light duty rolls varies between 1.1 and 5.6 kg/m. The heavy duty crusher diameters range between 900 and 1000 mm with face
The roll crusher consists of a pair of horizontal cylindrical manganese steel spring rolls (Fig. 13.14), which rotate in opposite directions. The falling feed material is squeezed and crushed between the rollers. The final product passes through the discharge point. This type of crusher is used in secondary or tertiary crushing applications.
