    CEMENT RAW MATERIALS International Cement Review

    cement clinker is manufactured by heating the blended and ground raw material (typically limestone and clay or shale and other materials) to partial fusion. the clinker burning takes place at a temperature of 1450c in kilns, which are normally inclined rotating cylinders lined with heat-resistant bricks.,belterra clay could replace limestone in cement production,oct 11, 2021 at least 50-60 per cent of limestone can be replaced by belterra clay, which provides several advantages when compared with limestone quarrying. the clay has to be removed anyway, so it does not have to be extracted only for cement production. furthermore, the burning process only requires 1250c 200c less than for portland cement.
