2020-11-4 · 2) Wet Process - Feed materials for the wet raw grinding circuit may involve materials stored relatively dry and, in the case of previously processed clay, in "slip" form at perhaps 60% - 70% moisture content. Emissions from the transfer of dry feed components to the mill are normally controlled by low temperature bag-type collectors.

The raw materials are further processed and ground. The grinding differs with the pyroprocessing process used. The raw materials are prepared for clinker production into a “raw meal” by either dry or wet processing. In dry processing, the materials are ground into a flowable powder in ball mills or in roller mills.
