Charah, Inc., an ash management provider for the coal-fired electric utility industry, and Ameren Missouri opened a limestone grinding facility at APAC Tennesseeís Brickey Quarry in Bloomsdale, Mo. The facility will process as much as 400,000 tons of limestone annually into powdered limestone for use at Ameren Missouriís Sioux coal-fired power plant. Powdered limestone is used as a reagent to capture sulfur dioxide emissions.
The Brickey Limestone Grinding Facility uses a series of hoppers and conveyors to move the limestone from a raw material storage building to two 85-inch Williams Patent Crusher roller mills. Once crushed, the limestone is stored in an 8,000-ton storage dome and then conveyed into one of two load-out silos.
Financial terms of the agreement were not disclosed.
