Abstract

The invention relates to a machine for compacting and/or crushing bulk material, in which two rollers which can be pressed together at high pressure each consist of a main roller body and a roller shell which is releasably connected to the main roller body and is composed of individual segments. Each of the individual segments has one single lug projecting in the circumferential direction on the front long side in the direction of rotation of the roller and one single complementary recess on the rear long side in the direction of rotation of the roller. The generatrices of the outer surfaces of the segments point in the circumferential direction and run radially with respect to the roller axis. This results in a simple construction of the segments and a high degree of security against tilting.
