Cement Rotary Kiln Rotary Kiln Cement Kiln
During working of cement rotary kiln, pulverized coal (natural gas) is burned in the cement rotary kiln to generate heat. the heat is used to heat the material by gas conduction or radiation. at the same time, as the kiln body rotates according to the designed inclination and rotation speed, the raw materials rolling forward periodically in the.
Manufacturing Of Cement By Dry And Wet Process
Feb 27, 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.
