Stone crusher pressure plate abutment - has plane surface working together with plane-faced pressure-transmitting element

摘要

The crusher has a conical channel (1) with a plate (2) pivoted around axis (3) by a toggle lever (4) driven from an eccentric (5) via connecting link (7). The end of the strut element (6) rests against an abutment surface forming the web part of a U-shape. The surface (11) is designed plane and the active end of the strut element has a plane face. At the moment of the maximum operating pressure, the two contact surfaces rest against each other at full face, so that the pressure is distributed over a maximum area.
