Ⅰ.Working principle: The big-sized material is evenly sent into the clearance between two rollers. Under the impact of two rollers' contrary rotation, the materials are extruded and crushed to the desired size. Ⅱ.Structure: The roll crusher is mainly composed of fixed roller, movable roller, machine frame, shield, protecting guard.

How Roll Crushers Work. Whether the application requires a single-stage or two-stage crusher, the forces necessary to perform the crushing remain the same: a combination of impact, shear and compression. The impact force occurs as the material enters the crusher and is impacted by the rotating roll.
