Abstract

A mobile crusher (2) is provided that can be displaced on four caterpillars and that includes a supporting frame (20), a large hopper (31), an apron conveyor (32), a sizer (34) and an intermediate conveyor (36) for use in strip-mining. The material is received by the shovel (1) of a shovel excavator or a wheel loader, is fed to the crusher (2), crushed and is then transferred onto a conveyor plant via a discharge conveyor system. The crusher (2) has to follow at the same cycle in which the shovel excavator moves forward during an advance in mining. In order to obtain a good maneuverability of the crusher (2), the two front caterpillars (22) are driven and can be steered like a two-caterpillar chassis. As the crusher (2) is subject to high loads, all components have to have a robust design. For this purpose, the individual functional groups are accommodated in a stable supporting frame (20). The crushed material is transferred onto a subsequent bench conveyor via an evolving conveyor directly connected to the mobile crusher (2), a transfer conveyor or a mobile bridge. The plant can be displaced while under full useful load.
