Raw Material: Kaolin ore ≤500mm, mud and moisture content ≤15%.
Kaolin Production Process: Raw material → Primary crushing → Secondary crushing → Screening → Grinding → Classification → Powder collection → Finished product.
Finished Product: 200～325 mesh (D90) kaolin powder, widely used in ceramics, coatings, papermaking and other industries.
Large kaolin ore is fed into a jaw crusher, crushed from 500mm down to 50～100mm.
The coarsely crushed material enters a counterattack crusher and is further reduced to 15～50mm.
The crushed ore is sent to a circular vibrating screen to remove fine mud and impurities.
Qualified particles (15～50mm) go to the grinding stage; materials larger than 50mm return to the counterattack crusher for re-crushing.
Crushed kaolin (15～50mm) is conveyed by a bucket elevator to a vibrating feeder, then fed into the Raymond mill grinding chamber. The material is pulverized into powder via rolling, impact and grinding action inside the mill.
The ground powder is classified by a powder selector. Unqualified coarse powder returns to the Raymond mill for re-grinding to form a closed-circuit cycle. Qualified fine powder (200～325 mesh) enters the collection system with airflow.
Qualified powder flows through pipelines into a dust collector for separation and collection.
The collected finished powder is conveyed to the product warehouse via discharging and conveying equipment, and finally loaded by powder tank trucks or packed by automatic packaging machines.
The entire kaolin grinding production line can form an independent production system for raw material processing, transportation, powder production, and final packaging. The layout of the entire production line is reasonable, with stable output, low investment, and high efficiency.
