Each "stage" consists of a riser pipe and a cyclone. In the riser pipe, hot gas ascends and raw meal is injected into the side and becomes entrained. Passing into the cyclone, the mixture is separated: the heated meal passes to the next stage down, and the cooled gas passes to the next stage up.
Here the Raw Meal gets preheated. It consists of 6 stages of cyclones. It is finally directed to the kiln via the dividing gate. There is also a swan neck arrangement for the gases such that the calciner can direct the hot gases to the 2 Nos. Perheater strings. The corresponding Smoke Chamber then directs the pre heated material to the kiln.
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.
Aug 30, 2012· Generally cement plants are fixed where the quarry of limestone is near bye. This saves the extra fuel cost and makes cement somehow economical. Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant. There are also various other raw materials used for cement manufacturing.
