  • Rotary Kiln – IspatGuru

    Calcination is generally used in the creation of inorganic materials. They are used for the calcination of limestone, dolomite, and magnesite. Though coarsely crushed limestone can be converted to quick lime by heating in the shaft furnace, the rotary kiln is preferred for particle sizes of 60 mm or less since it delivers a more uniform product at a higher rate. This quick lime is particularly
