Project Background
Roberts & Schaefer Company was awarded a turnkey contract from Foster Wheeler USA for engineering, procurement, construction, and commissioning of the limestone handling system at JEA’s Northside Generating Station in Jacksonville Florida. The system was successfully completed and in operation in 2002.
The limestone handling system is designed to receive the limestone at the limestone preparation building. The building houses three identical grinding and drying systems. Each grinding and drying system is fed by a 50 TPH conveyor that feeds the limestone to an impactor. The impactor feeds the limestone dryer/mill. The product from the dryer/mill is transported via a pocket conveyor to a limestone screen feeder that moves the product to sizing screens. Oversized products from the sizing screens are directed back through the dryer/mill for reprocessing. The proper sized product is sent to a surge bin. A pneumatic transport moves the product from the surge bin to the limestone silos at the boiler house. Ancillary systems for the limestone preparation building include bag house dust collection and ventilation.
