The produced clinker is then mixed with gypsum and ground once more to form the cement. The plant processes 65 MT/h of clay, 260 MT/h of limestone and 12.5 MT/h of gypsum to produce 220 MT/h (1.75 ...
This reduces the capital costs of a new cement plant. A dry process kiln might be only 70m long and 6m wide but produce a similar quantity of clinker (usually measured in tonnes per day) as a wet process kiln of the same diameter but 200m in length. For the same output, a dry process kiln without a precalciner would be shorter than a wet ...
