Abstract
A mobile collapsible screen and cone crusher combination where the screen is pivoted forward and downward for transport and a rubber hopper is coupled to the fines conveyor so as to permit a hinged connection and a sliding connection between the flexible hopper and the fines conveyor. A plurality of flexible matter edge plates are used at the rear of the flexible hopper to facilitate proper compression and expansion of the flexible hopper. A selectable maintenance catch is used to allow the screen to be elevated to an intermediate height for maintenance.
