IMPROVEMENTS TO RING-ROLLER CRUSHER

摘要

The invention concerns a crusher consisting of a ring (10) with horizontal axis, means for driving the ring in rotation about its axis, at least one roller (16) whereof the axis is parallel to that of the ring and which is placed inside the latter so as to roll on its internal surface and elastic means (30) pressing the roller on the ring, the roller being supported at its ends by two arms (22) fixed on the crusher frame so as to pivot about an axis parallel to the ring axis. In order to limit the canting of the roller while limiting the crushing pressure and, thereby the mechanical stresses to acceptable values, the arms (22) are mutually linked by a torque shaft (24) parallel to the rotation axis of the arms.
