FIELD: material working. SUBSTANCE: device has a supporting and additional frameworks. Rollers with disks are fixed in them parallel to each other for possible rotation. The additional framework is made in the shape of a hinged four-link chain and is disposed over the supporting one with a slope relative to it, spring-loaded and can be rotated in the vertical plane. The longitudinal links are hinged with the rollers, the cross-sectional ones are equipped with a pusher. The connection of the supporting and additional frameworks is exercised at the expense of bearing members in the guides. The bearing members are attached to the supporting framework by means of screw mechanisms and are hinged with the additional framework. The disks of every roller are shifted relative to those of the next roller forming an identical interdisk gap. EFFECT: improved grinding and separating of loose materials. 3 dwg
