SQUEEZER Russian patent published in 2017 - IPC B30B11/16 B30B15/00 

FIELD: machine engineering.

SUBSTANCE: squeezer of the roller press contains a core, along which the lining is fastened. The cover consists of segments with end faces facing each other. The segments on the front side are provided with circumferentially extending lugs with first tight surfaces. Each segment is fixed to the core with the possibility of detachment by means of at least one retaining ring. Segments are made with external amplifiers of the material. Mentioned amplifiers are located on the end surfaces and/or on the protracted shoulder of the segments and protrude outwardly with respect to the first clamping surface in the radial direction and/or with respect to the end surface in the axial direction. In this case, pocket-like recesses arranged in the circumferential direction between the external amplifiers of the material are formed with the first protruding surfaces to which the second protruding surfaces of the fastening ring abut.

EFFECT: increasing the strength of the segments and simplifying the installation of the squeeze shaft.
