Roll Crusher Polysilicon

Mode of Operation. The material is crushed by shear- and tensile forces generated by high rotor torques at a low circumferential speed. Due to the arrangement of the crushing tools the fines in the feed can pass through the crushing rolls similar to a roller screen without being crushed.

To provide optimum protection for the roll crusher, a hydraulic floating roll retraction system has been developed based on the successful system used in HAZEMAG impact crushers. According to the product required, the roll is retained hydraulically in position with a precise and constant gap setting, thereby guaranteeing a product of uniform ...
