Roller bearing adjustment system for comminution mill has bearing blocks at ends of rollers held between upper and lower beams and pushed apart by hydraulic actuators

摘要

The frame (10) has upper (2) and lower beams (8) holding bearing blocks (20,22) at each end of the rollers. The beams are joined by a central crosspiece (12), making an H-shape lying on its side. The first bearing block on each side may be moved by an adjustment screw (24) against the action of two hydraulic actuators (26,28). The second block on each side may be moved by a screw (52) against pressure pads (33,35). The screws pass through bridging pieces (4,6) engaging in slots in the upper and lower beams.
