Project Background
Roberts & Schaefer Company was awarded a turnkey contract from Black & Veatch for engineering, procurement, construction, start–up and commissioning of the limestone and gypsum handling systems at American Electric Powers Cardinal Plant in Brilliant, Ohio. The systems were successfully completed and in operation in 2007.
The limestone handling system is designed to receive limestone from river barges at a receiving hopper with vibratory feeder. The limestone is conveyed at 1,000 TPH to a 27,000–ton limestone storage pile and discharged through a telescopic chute. Limestone is reclaimed from the active storage pile with two vibratory feeders and conveyed at 375 TPH to two storage silos with provisions for a third silo at the limestone preparation building. An emergency reclaim hopper with vibratory feeder is also provided near the pile.
The gypsum handling system is designed to receive gypsum from the process filters onto dual conveyors at 225 TPH each. One conveyor with telescopic chute conveys the gypsum to a 6,800–ton waste gypsum stockpile. The other conveyor conveys the gypsum to an enclosure to form a 16,000–ton commercial gypsum stockpile. Gypsum is reclaimed from the commercial pile by two hoppers with belt feeders and conveyed at 1,000 TPH to a traversing hopper with telescopic chute for barge loadout.
