Abstract
A mobile crusher () is provided that can be displaced on four caterpillars and that includes a supporting frame (), a large hopper (), an apron conveyor (), a sizer () and an intermediate conveyor () for use in strip-mining. The material is received by the shovel () of a shovel excavator or a wheel loader, is fed to the crusher (), crushed and is then transferred onto a conveyor plant via a discharge conveyor system. The crusher () 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 (), the two front caterpillars () are driven and can be steered like a two-caterpillar chassis. As the crusher () 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 (). The crushed material is transferred onto a subsequent bench conveyor via an evolving conveyor directly connected to the mobile crusher (), a transfer conveyor or a mobile bridge. The plant can be displaced while under full useful load.
