 · In short, the manufacture of cement is done in a silo. Then the raw meal will be blended by passing compressed air to obtain a coagulated and uniform mixture. Compressed air will be induced upward. The upward movement of the powder will decrease the apparent density. The air will then be pumped over the quadrant of the silo.

The production process for cement consists of drying, grinding and mixing limestone and additives like bauxite and iron ore into a powder known as raw meal . The raw meal is then heated and burned in a pre-heater and kiln and then cooled in an air cooling system to form a semi-finished product, known as a clinker. Clinker 95 is cooled by.
