semi-dry/semi-wet or wet depending on how the raw material is handled before being fed to the kiln. Moisture content of the raw materials (ranging from 3% for hard limestone to over 20% for soft limestones such as chalk) is the main criterion for governing the process used. In the dry process the feed material is in a dry, powdered form.
