cement clinker quality control during clinker production

Current Location : Home > cement clinker quality control during clinker production

  • What is the manufacturing process of Portland Cement

    The fused mass turns into a nodular form of size 3 mm to 20 mm known as clinker. Then the clinker is cooled under controlled conditions in a rotary cooler. The clinker is stored in silos or bins. Generally the clinker weighs about 1100 to 1300 gms per liter. The liter weight of the clinker indicates the quality of the clinker.
