Crushing roller for single- or multi-roller crusher

摘要

The crusher has several crushing segments resting on machined surfaces on a hollow body. There is a longitudinal groove (4,5) of angular cross section in the hollow roller body either side of a radial plane (b) in its surface covered by the angle of one of the segments (3). One surface (6,7) of the groove is planar and faces a corresponding surface (7,6) of the other groove (5,4) in the same plane (c). The other surface (8,9) is parallel to a corresponding surface (9,8) of the groove (5,4) of the adjacent radial plane (b).
