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.

As a result, the quarry expects fuel and maintenance savings from less truck usage.
