vertical shaft kiln in which the nodules are converted into clinker consists of a cylindrical shell with conical portion at the top and lined with fire bricks.
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 ...
