Kaolin Grinding and Processing

Kaolin clay grinding processing is a complex and delicate process, aiming to convert kaolin raw materials into powder products with different fineness and quality requirements. It is mainly used to make daily ceramics, industrial ceramics, building sanitary ceramics, and refractory materials. It is also used as a filler or white pigment in papermaking, construction, coatings, rubber, plastics, textiles, etc.

Processing scheme

Depending on the characteristics and output requirements of kaolin, different crushing equipment can be selected for crushing. Common crushing equipment includes jaw crushers, impact crushers, hammer crushers, etc. These equipment are capable of crushing kaolin materials to the required particle size. Usually, this fineness range is between 15mm and 30mm.
The crushed kaolin small pieces are sent to the storage hopper through the elevator and then sent into the grinding chamber of the mill through the feeder for grinding. The kaolin is ground into the required powder through the rotation of the grinding roller and the grinding ring.
The grading system will screen the materials and return the unqualified powder to the host for re-grinding to ensure that the particle size of the powder meets the requirements. Qualified powder enters the next stage through the pipeline.
Kaolin powder that meets the fineness will enter the dust collector through the pipe with the airflow for separation and collection. The collected finished powder is sent to the finished product silo by the conveying device through the discharge port for packaging.
