CLIRIK Kaolin Grinding Mill Fine Ore Powder Grinder Factory

What is Kaolin?

Kaolin also named kaolin clay and china clay.
kaolin powder
Kaolin is a non-metallic mineral, a kind of clay and clay rock dominated by kaolinite clay minerals.
The pure kaolin is white, fine, soft and soft, with good plasticity and fire resistance and other physical and chemical properties.
Its mineral composition is mainly composed of kaolinite, halloysite, hydromica, illite, montmorillonite, quartz, feldspar and other minerals.
Kaolin is mostly dull, white and fine when it is pure, and may have gray, yellow, brown and other colors when it contains impurities.
Depending on its origin, the appearance can be loose soil blocks and compact rock blocks. The density is 2.54-2.60 g/cm3. The melting point is about 1785°C.
With plasticity, wet soil can be molded into various shapes without breaking, and can remain unchanged for a long time.

Kaolin application field

Kaolin has a wide range of uses. It is mainly used in refractory materials, papermaking, ceramics, and can also be used in coatings, rubber, plastics, pigments, cosmetics, medicine, textiles, chemicals and other industries. The following is an introduction to the production of kaolin Craft.

Insulation Materials

Kaolin has high whiteness, soft quality, easy to disperse and suspend in water, good plasticity and high cohesiveness, and excellent electrical insulation properties;


Kaolin has good acid solubility, low cation exchange capacity, good fire resistance and other physical and chemical properties. Therefore, kaolin has become a necessary mineral raw material for dozens of industries such as papermaking, ceramics, rubber, chemicals, coatings, medicine and national defense.

High-tech field

In Japan, kaolin is also used to replace steel to make cutting tools, lathe drill bits, and internal combustion engine housings.
Especially in recent years, the rapid development of modern science and technology has made the application fields of kaolin more extensive. Some high-tech fields have begun to use kaolin as a new material. Even the high-temperature porcelain components of atomic reactors, space shuttles and spacecrafts also use kaolin. production.


Calcined kaolin for papermaking is made from high-quality coal-series kaolin as raw material, through ore beneficiation, ultra-fine grinding, and calcination.
It has a relatively complete hexagonal sheet structure, good porosity, reasonable particle size distribution range and excellent light scattering characteristics.

Coating and pigments

Kaolin is an excellent paint pigment due to its high whiteness, low abrasion value and good oil absorption. It is mainly used as a top coat in the paper industry. It has the characteristics of reducing production costs, improving paper performance, increasing ink absorption, good compatibility with other components, and high viscosity.

Kaolin powder processing technology

kaolin powder processing plant

The first stage: drying of kaolin

Kaolin is used to dry raw materials through a dryer or a kaolin grinding mill with hot air according to the moisture content.

The second stage: kaolin feeding

The small pieces of kaolin after being crushed by the kaolin powder are sent to the storage hopper by the hoist, and then sent to the grinding powder machine room evenly and quantitatively by the feeder for grinding.

The third stage: Grinding and grading

The fine powder after kaolin grinding is classified by the classification system, and the unqualified fine powder is classified by the classifier and returned to the main machine of the vertical mill for re-grinding.

The fourth stage: the collection of finished products

The powder that meets the fineness is separated and collected in the dust collector through the pipeline through the airflow. The collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then is packaged by a powder tanker or an automatic baler.

Kaolin grinding mill equipment

At present, the conventional equipment for processing fine powder of kaolin below 400 mesh is YGM Raymond mill, high-pressure medium-speed mill, etc., which can process kaolin ore into finished products with different specifications of 80-400 mesh.
The complete configuration of kaolin grinding mill includes jaw crusher, bucket elevator, vibrating feeder, mill host, classifier, powder collector, pulse dust removal system, air compressor, electrical control system, and corresponding milling machine The supporting milling equipment.
The CLIRIK kaolin grinding mill has a unique crushing cavity structure and advanced classification device to ensure that the equipment can achieve ultra-fine powder processing. It is especially suitable for the processing of products with high whiteness requirements such as kaolin, calcite, ash calcium powder, etc. It has the characteristics of high whiteness, fine particle size, and no black slag.
