Rotary batch mixer produces uniform blends while maintaining ingredients’ original particle sizes
An ash-management company installs a rotary batch mixer in a new processing plant to produce high-quality cement products and keep operation costs low.
Charah Inc., headquartered in Louisville, Ky., provides ash-management services to the coal-fired electric utility industry. In 2004, the company decided to build a processing plant in the northeastern US to mix lightweight bottom ash with sand, gravel, fly ash, and cement to produce and package up to 20 different cement products. When specifying mixing equipment for the plant, the company wanted an energy-efficient batch mixer that would rapidly produce 100 percent uniform blends without degrading the bottom ash.
