CONVEYORS DRIVE DOWN COSTS Charleston Stone sits on about 1,000 acres in southern Illinois. To cover this much ground and overcome the problem with the river, CMW recommended multiple conveyor systems to improve efficiencies and reduce costs. The first conveyor CMW installed is a portable 80' long material handling system that moves with a portable crusher. "It goes back and forth because we grind from two locations," says Mike Vaughn, plant superintendent. The portable conveyor feeds to a second 300' conveyor that crosses the river. "We wanted to combine two plants into one and the river was splitting them apart. Conveyors were the only practical solution," says Jerry Tarble. Conveyor #2 transfers rock onto a third conveyor that runs 1,165' up a hill to the main plant. Conveyor #3 feeds onto a fourth that pulls off rip-rap. The remaining limestone is transferred to a fifth conveyor - a stacker that builds the surge pile. Lastly, conveyor #6 carries rock out of the reclaim tunnel under the surge pile to feeders that provide consistent flow to the crushers. "The consistent feed is definitely a very big plus for us. It helps make sure we produce good quality aggregate - all the same shape and size," says Mike Vaughn. THE RESULTS ARE IN |
