Vertical Shaft Klin/VSK

Raw Materials :

1.                  Limestone (purity not less than 88% Total Carbonate)

2.                  Clay  ( Black Soil ) should be buttery

3.                  Coke Breeze / Petro Coke

4.                  Laterite ( Used if Clay do not have 16% Fe2O3)

5.                  Gypsum (Additive used during Clinker Grinding)

1. Raw Mill Section :

All the raw materials should be of  less than 25 mm size. If the size of the raw material is bigger than 25 mm, It has to be crushed through a crusher and Hammer Mill. All the materials are crushed stored in the storage yards through belt conveyors.

Now, the raw materials are taken as per their required percentage with the help of a weigh belts( Control by PLC ).The measured materials is went to feed belt conveyor and after that shifted to a feed hopper through elevator .The feed of material is controlled with the help if ratchet Feeder/Table feeder.

This feeder controls the fineness of grinding. This material is ground fine in the raw Mill. The mill out put size is maintained as 94% passing through 100 mesh.
