RAW MATERIALS FOR CEMENT MANUFACTURING
Know More

Sulphur appears as sulphides from pyrites It forms SO 2 in the kiln and with alkalis and oxygen it forms alkali sulphates which vaporize in the burning zone of the kiln and condense on the raw meal in the colder zone Though some amount of alkali sulphate in the clinker is of advantage for early strength high sulphur content can result in increased SO 2 emission choking of suspension pre...
