Transferable stone crusher plant - has vertically movable plate underneath hopper serving as supporting wall for filled in ramp

摘要

The transferable cursher plant has the top edge of the feed hopper as low as possible, but at the same time the lower end of the conveyer belt has a sufficient clearance above ground. The plant /1/ consists of crusher /2/, feed hopper /3/ with top edge /4/ and conveyer belt /5/. Beneath the conveyer belt /5/ a second belt /11/ is provided for the disposal of mud and fines. The curshed material drops on transfer belt /6/ for further handling. On the entry side of the plant retaining wall/7/ an arm /8/ hinged to fulcrum /9/ is fixed to the frame structure. The wall /7/ is vertically movable by cylinder /10/. During the transfer operation of the plant the wall /7/ is in a lifted position, when the plant arrives at the working site, the wall is lowered to form a retaining surface for the ramp /12/.
