UP, UP AND AWAY - VERTICAL BELT CONVEYOR FOR MUCK REMOVAL

A system of continuous muck removal developed by the zoker corporation, Illinois, designed for tunnelling operations, is described. Said to be the world's first vertical belt conveyor system, the design uses a vertical 1.6 M wide flexowall rubber and steel reinforced belt. This belt has rubber pockets able to deform in either direction as the belt passes the pulleys. Belt drive is by a 1500 mm diameter pulley at 28 rpm with power supplied by two 200 hp electric motors. The lump size that can be accepted by the belt is limited and the muck, which is hauled in rail cars, is tipped by a rotary tippler through a coarse screen. The muck passes up a 914 mm wide belt conveyor which feeds the vertical belt. The system, as installed on Chicago's tarp project, offers a capacity of 900 tonne/h of dolomitic limestone through a vertical lift of 82 M. (TRRL)
