Saurashtra Cement Ltd., Ranavav is a dry process Cement Plant using latest Precalciner Technology (Inline as well as Separate Line Calciner).
Limestone from captive mines is crushed to size of less than 100 mm and stacked with the help of Stacker in horizontal layers in the form of a pile. Corrective materials such as Iron sludge/Iron ore, Marl, Tailing Waste is also added in the pile.
The pile thus prepared is cut vertically with Reclaimer and fed to Vertical Roller Mill for grinding as powder. As per the requirement of quality norms other corrective material (Marl) is added to Raw Meal during grinding. The ground material is fed to the blending silo for homogenisation. The blended Raw Meal is fed to Kiln for burning.
Raw Meal fed to the Preheater tower is calcined upto the required level (more than 85 % calcination) and enters into the Kiln where sintering takes place. Clinker is formed at the temperature of around 1350oCto 1450oC. Coal is fired in calciner as well as in Kiln to provide energy for calcination and sintering process. Hot Clinker is air cooled in IKN KIDS and Pendulum cooler for stabilisation of phases of Clinker.
