Production Process Flow

1. Imported ingredients: Alumina and iron are imported as minor processing additions.
2. Mining and crushing: Limestone (calcium) and silica are mined from the quarry and conveyed to the plant.
3. Raw Material Storage: Limestone (calcium), iron, silica and alumina are stored in large silos.
4. Blending: All raw ingredients are blended in proportion to prepare for grinding.
5. Raw Grinding: Raw ingredients are ground to fineness of baby powder and further blended into a homogeneous mixture.
6. Heating and Cooling: The ground mixture is fed into the kiln through a tall preheating tower, where it is heated and rapidly cooled to create clinker.
7. Clinker Storage: Clinker is stored in a large dome and silo waiting to be ground into cement.
8. Finish Grinding: Clinker is ground into the fine gray powder recognized as cement, adding a small amount of gypsum to control the time of setting.
9. Cement Storage and Shipping: Finished cement is stored in a silo awaiting loading into trucks or railcars.
