• RAW MATERIALS FOR CEMENT MANUFACTURING Mechanical

    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
