325 mesh kaolin powder is widely used in the paper industry. Choosing a high-quality kaolin grinding mill can ensure the fineness and quality. Kaolin can be the filler used in the papermaking process, it is also used as a pigment in the surface coating process. In papermaking, kaolin offers good covering performance and good coating gloss performance, and can also increase smoothness and printability of the paper, which can greatly improve the quality of the paper.

Kaolin dry grinding Process flow:

Dispersion – Sand Removal – Classification – Magnetic Separation and Iron Removal – Flotation – Bleaching – Ultrafine Grinding – Surface Modification

1.Kaolin powder plant- HC Raymond mill

Raymond mill is suitable for processing non-flammable and non-explosive minerals with Mohs hardness below 7 and humidity below 6%, such as gypsum, talc, calcite, limestone, marble, potassium feldspar, barite, dolomite , granite, kaolin, bentonite, medical stone, bauxite, red iron oxide, iron ore, etc. The final fineness between 80-400mesh. Through the combined action of the analyzer and the fan, it can meet the requirements of different users. Compared with the ball mill, Raymond mill has the advantages of higher efficiency, lower power consumption, less footprint, small capital investment and environmental protection.

Mill Model: HCQ1500/HC1300/1700/1900/3000

Fineness: 38-180μm

Capacity: 1-55t/h

Mill characteristics: this kaolin Raymond mill has higher production, grinding and classification efficiency, environmental protection, noise reduction,dust removal rate as high as 99%.

2. Kaolin powder plant- HLM vertical mill

Vertical mill is an industrial large-scale grinding equipment which is widely used in cement, electric power, metallurgy, chemical industry, non-metallic mining, etc. It integrates crushing, drying, grinding, grading and conveying in one set. It can grind block, granular and powdery raw materials into fine powders.

Mill Model: HLM800/1100/1300/1700/3200

Fineness: 22-180μm

Production capacity: 5-100t/h

Mill characteristics: this kaolin vertical mill has superior drying capacity, diverse applicable materials, high throughput rate, even powder particle distribution, stable operation and reliable performance.
