Dry- and Wet-Mix Process Shotcrete| Concrete …

The two basic methods for applying shotcrete are the dry-mix process and the wet-mix process. The term gunite is frequently used when referring to the dry-mix method; other terms such as air-placed concrete, gunned concrete and sprayed concrete have also been used in the past to describe the process.

Manufacturing - the cement kiln - Understanding Cement

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 process kiln but longer than a dry process kiln with a precalciner.
