Abstract:

The cause of the breakage of refractory for the active lime rotary kiln is analyzed. It is thought that the adhering material on the lining of the rotary kiln is related with the reaction of silica and iron oxide, and calcium silicate and calcium oxide are main components for ring formation. The improvement of refractory can raise the service life of the rotary kiln.
