• We manufacture cement through the Vertical Shaft Kiln using the 'Black Meal process'.
• The VSKs (Vertical Shaft Kiln) are fed with the raw 'Black Meal' of appropriate composition in the form of nodules.
• The sintering is normally completed within the conical portion, which is specially designed to accommodate shrinkage of nodules.
• The various zones of reaction starting from the top of the kiln are :

- Preheating zone
- Calcining zone
- Sintering zone
- Cooling zone

• The combustion air is supplied by roots blower. This air, ascending from below in the cooling zone absorbs heat from the descending clinker. The whole kiln charge composed of unburnt nodules and clinker rests on a specially designed grate rotating slowly at the bottom of the kiln and mounted over kiln shaft.

• The grate is driven with the help of variable speed motor in order to control the discharge rate of clinker. The clinker is finally extracted from kiln bottom through triple air lock discharge gates.
