Expanding quarry cuts conveyor splicing downtime with riveted-plate belt fasteners
After a cold-bond splice fails on a segment of a long pit-exit belt conveyor, a limestone quarry switches to a mechanical splice.
Stony Creek Stone Company quarries material from a limestone deposit about 20 miles north of Indianapolis, Ind. Before mid-1991, the quarry's conventional operation hauled quarried material topside with trucks and crushed it outside the quarry pit. The quarry has expanded, and a new operation now crushes the material in the pit and moves it topside with a belt conveyor. Trucks are used only to feed the in-pit crusher. As a result, the quarry expects fuel and maintenance savings from less truck usage.
