ACC FOUNDATION
Many men of outstand initiative and foresight contributed
towords the development of cement industry in India. About 71

RAW MATERIAL FEEDING
Lime stone feeding to Raw Mills/Roller Mills is through the
sequence of belt conveyors to different Hoppers. Feed size of
limestone is 90 mm and Mills Scale, Shale feeding is from the
Gantry to the respective Hoppers through sequence of belt
conveyors. Shale feeding is through Reclaimed or Pay
Loader.
RAW MILL
Two close circuits two chamber Ball Mills are performing the
grinding of limestone and Additive mix. Raw Mill is a tube
construction of thick MS plate with steel lines and
compartments are separated by diaphragm for improving the
retention time and transfer of materials in second for further
grinding. Mill is charged with hyper steel balls. Raw material is
first fed to Tertiary Crusher (Single Rotor Reversible Impact
Crusher) which reduces the size of Mix. After crushing the mix
the material is fed to Ball Mill where fine grinding takes place.
The finer product is separated by Air Separator and is fed to the
blending silos and the coarse material is fed back to the Mill
Inlet.
