Bluegrass Materials Plant Renovations

Location: Bowling Green, KY

Challenge: Renovate a quarry in operation since the 1950s. 100% of product extracted must be turned into product. 0% waste.

Solutions: Plant remake with a Lippman jaw crusher as the centerpiece.

...Process Machinery was tapped to bring the new plant design to fruition.

The heart of the new 400+ tph plant is a Lippman heavy duty 36 x 50 jaw crusher. Material from the quarry face is delivered to the crusher by two Euclid 60-ton haul trucks, which are first loaded by a Caterpillar 988G loader. “Material from the jaw can be scalped to make rip rap or base if we want to,” Ted Baker said. “Then a stacker moves material to two surge piles for asphalt stone and concrete stone.” Next, material is conveyed to a 4 ¼ Symons secondary cone crusher, which was a carryover from the old plant. “The deposit, which consists of four distinct ledges, is not characterized by highly abrasive material,” Ted Baker said. “This keeps us from having to change the wear liners.

”Material then splits off to two 8 x 20 quadruple-deck Deister screens. An Impact Service Corp. vertical shaft impactor is used for the tertiary phase. “We do no washing at all at the plant,” Ted Baker said. “Material goes to a Sturtevant 16-ft. Whirlwind air classifier which creates the sand product we sell. We also make lime at the plant. We turn 100 percent of the material we run into product. There is no waste.”
