Automated conveyor walks to keep pace with muck pile.
Rock Products 1983 Jul; 86(7):37-39
A change in quarrying methods, combined with an automated conveyor system to handle the plant feed material from the face to the main plant area, has allowed Granite Rock Co. to realize a 30% savings in operating and maintenance costs. The key to this saving was two factors: the elimination of drilling and blasting, and a complete change in the way the primary processing was handled. At the same time, the company erected a new primary screening facility at the main plant area. Ripping the stone with D10 bulldozers and shoving the ripped material over the edge to the quarry floor has virtually eliminated drilling and blasting for the past two years. Some shooting is planned in 1983, to assist the ripping.
