There are four types of kaolin powder processing: coarse powder processing (0-3MM), fine powder processing (20 mesh-400 mesh), ultra-fine powder deep processing (400 mesh-1250 mesh) and micro powder processing (1250 mesh-3250 mesh)

The kaolin powder making process is divided into four stages: crushing, grinding, grading, and powder collection;

Stage One: Broken

The bulk kaolin materials are crushed by the crusher to the feeding fineness (15mm-50mm) that can enter the grinding mill.

Second stage: grinding

The crushed kaolin small pieces are sent to the silo through the elevator, and then sent to the grinding chamber of the mill uniformly and quantitatively through the vibrating feeder for grinding.

For fine powder processing, LM vertical roller mill, MTW European version mill, and 5X European version smart mill can be used;

For ultra-fine powder processing, MW ring roller micro-powder mill and LUM ultra-fine vertical mill can be used; for coarse powder processing, CM European-style coarse powder mill can be used.

The third stage: grading

The ground materials are classified by the powder selector, and the unqualified powder is classified by the powder selector and returned to the main machine for re-grinding.

The fourth stage: gathering fans

Powder that meets the fineness will enter the dust collector with the air flow through the pipe for separation and collection. The collected finished powder will be sent to the finished product silo through the conveyor through the discharge port, and then packaged in a powder tanker or automatic baler.
