Once the kaolin is extracted, it is transported, usually via truck, to processing plants that are near the mine. Kaolin can be either dry processed or wetprocessed depending on its usage. Dryprocessed kaolin mainly is used in the rubber industry. In dry processing, the raw kaolin is crushed into the desired size and dried using rotary dryers.

Soft materials are more difficult to mill and to reduce their particle size, explaining the longer milling time for kaolin I (180 min) in comparison to kaolin R (120 min) [30]. Kaolin R is formed by kaolinite (JCPDS 291488) and anorthosite (JCPDS 200528), with small amount of quartz (JCPDS 461045) ( Fig. 5 ).
