AES – Amos Plant
- Owner: American Electric Power
- Project: Limestone and Gypsum Handling Systems
- Location: Amos Plant, Winfield, West Virginia
- Scope: Engineering and Procurement
Project Background
Roberts & Schaefer Company was awarded a contract from American Electric Power for engineering and procurement of the limestone and gypsum handling systems at American Electric Power’s AMOS Plant in Winfield, West Virginia. The systems were successfully completed and in operation in 2007.
The limestone handling system is designed to receive limestone from barges at the receiving hopper with a belt feeder. The limestone is conveyed at 1,500 TPH and discharged through a telescopic chute to a 22,000-ton limestone storage pile. Limestone is reclaimed from the storage pile with two hoppers, one with a variable speed belt feeder and the other with a variable speed feeder/breaker. An emergency hopper with belt feeder is also provided. The limestone is conveyed on dual conveyors at 500 TPH each to three storage silos at the limestone preparation building and fed to the silos by chute work or transfer conveyors. The limestone handling system is provided with water type or fog type dust suppression.
The gypsum handling system is designed to receive gypsum from the vacuum filters onto two conveys at 300 TPH each. One conveyor transfers the gypsum to a 5,000-ton gypsum standby pile for truck loading with mobile equipment. The other conveyor conveys it to a transfer tower and onto a radial stacker to form a 15,000-ton gypsum stockout pile.
