  • The cement kilnUnderstanding Cement

    The original rotary cement kilns were called wet process kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter. It has to be long because a lot of water has to be evaporated

    Heat generated in the grinding process causes gypsum (CaSO 4.2H 2 O) to lose water forming bassanite (CaSO 4.0.2-0.7H 2 O) or γ-anhydrite (CaSO 4. 0.05H 2 O). The latter minerals are rapidly soluble and about 2 of these in cement is needed to control tricalcium aluminate hydration. If more than this amount forms crystallization of gypsum
