    The materials are then fed through a kiln at 2,600º F to produce grayish-black pellets known as clinker. The alumina and iron act as fluxing agents which lower the melting point of silica from 3,000 to 2600º F. After this stage, the clinker is cooled, pulverized and gypsum added to regulate setting time.

    Another key advantage is that CSA cements are also significantly greener. Portland cement is fired in kilns at temperatures of around 1500°C (2700°F), whereas CSA cements only need to be fired at temperatures of around 1250°C (2250°F). The resulting CSA clinker is softer than OPC clinker, requiring less energy to grind.

  • Cement Kilns: Grate Coolers

    The clinker progresses through the cooler by moving more-or-less horizontally along the grate, and so the direction of the cooling air is roughly at right angles to the direction of movement of the clinker, and the cooler functions as a cross-current heat exchanger. This mechanism is inherently less efficient than a counter-current heat ...
