Modern, Efficient Preheater Rotary Kilns Greer Lime Company

May 25, 2012 We produce lime on two modern, efficient preheater rotary kilns. Our kilns As hot gas from kiln fuel combustion is drawn through the preheater, heat is transferred to the stone to start the calcination process. Calcination is the process by which limestone is heated to chemically convert the stone to lime.
