burning: in this operation, the slurry is directly fed into a long inclined steel cylinder called a rotary kiln.in this kiln there are 3 different zones shown in fig. below. cement manufacturing process flow chart (i) drying zones: in the wet process, the drying zone is comparatively larger than the dry process. it is because the raw material in slurry form is directly fed into the kiln which,cement manufacturing process | phases | flow chart,cement manufacturing process phase ii: proportioning, blending & grinding. the raw materials from quarry are now routed in plant laboratory where, they are analyzed and proper proportioning of limestone and clay are making possible before the beginning of grinding. generally, limestone is 80% and remaining 20% is the clay.
the kiln has to operate continuously in order to ensure a steady regime, and therefore uniformity of clinker. the larger existing kiln in a wet process plant produces 3600 tonnes of clinker per day. the manufacture of cement by wet process is energy intensive and thus uneconomical as compared to dry process and semi dry process.,internal audit cement industry - icmai.in,about cement manufacturing, its process, elements of costs etc.. few facts about cement 1. types of cement-opc-ordinary portland cement ppc-portland pozzlana cement slag cement etc with different grades like 33, 43,53 4
