Segmental shell for a coal crusher roll including specialized removal means |
摘要 |
A coal crusher roll includes a smooth tubular cylindrical back-up roll having a series of regularly spaced tapped radial holes to receive bolts by which eight identical shell segments may be fastened on the back-up roll. The holes at the axial ends of the segment are undercut to provide a rabbet into which fits the tang of a special lifting hook by which the segment can be easily handled by a lightweight crane. A recess in the central part of the segment defined by a peripheral berm around the backside of the segment reduces the weight of the segment, provides a place for receiving balancing weights, and simplifies the face fit machining for the segment with the back-up roll.
