lime create rotary kiln proces

the kiln dries, heats, and calcines the counter-flowing lime solids. Rotary lime kilns in the pulp and paper industry range in size from 7 ft (2.1 m) in diameter by 175 ft (53 m) long to 13.5 ft (4 m) in diameter by 400 ft (122 m) long. The refractory lining is from 6 in. (15.2 cm) to 10 in. (25.4 cm) thick. Production
