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.
Claims15
A mobile material processing plant comprising:
- a mobile frame support;
- a vibrating screen plant for separating material;
- a pivoting screen support leg, coupled to said mobile frame support and said vibrating screen plant, so that said vibrating screen plant can be simultaneously lowered and moved forward with respect to said mobile frame support;
