    OverviewThe manufacture of cement clinkerEarly historyThe rotary kilnThe wet process and the dry processPreheatersPrecalcinersAncillary equipment

    Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates. Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant. As the main energy-consuming and greenhouse-gas–emitting stage of cement manufacture, improvement of kiln efficiency has been th

    However, new cement kilns are of the 'dry process' type. Dry process kilns. In a modern works, the blended raw material enters the kiln via the pre-heater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the ...

    For calculating the kiln speed we require following details. The formula is % of Filling Level = (3.2*production in tpd)/(Effective dia of kiln^3*kiln slope*kiln rpm) Based on this universal formula in which all the cement plants use you can back calculate the kiln rpm based on what filling level your are maintaining.
