WHAT IS KAOLIN　　

Kaolin is a common clay mineral in nature and a very important non-metallic mineral. Because of its white color, it is also called dolomite. The pure kaolin is white, fine, soft and soft, with good plasticity, fire resistance, suspension, adsorption and other physical properties. The world is rich in kaolin resources, with a total amount of about 20.9 billion tons, which is widely distributed. Countries such as China, the United States, the United Kingdom, Brazil, India, Bulgaria, Australia, Russia and other countries have high-quality kaolin resources. my country's kaolin mineral resources rank among the top in the world, with 267 proven mineral deposits and proven reserves of 2.91 billion tons.

USES OF KAOLIN

With the continuous economic development, the role of kaolin in social production has become increasingly prominent, and it is an essential mineral raw material for national economic construction. It is also widely used in industrial sectors such as rubber, plastics, refractory materials, petroleum refining, and cutting-edge technology in agriculture and national defense.

1. Paper industry:

Kaolin is used in papermaking, which can give the paper good covering performance and good coating gloss performance. It can also increase the whiteness, opacity, smoothness and printability of the paper, and greatly improve the quality of the paper.

2. Ceramic industry:

Kaolin is used in the field of ceramics, which is conducive to the formation of mullite and improves its chemical stability and sintering strength.

3. Petrochemical industry:

Kaolin can be used as a catalyst filler for petroleum cracking, and kaolin has high purity, which is good for making catalyst carriers.

4. Coating industry:

The main role of kaolin in paint is filler and pigment substitute.　

5. Rubber field:

Nano-grade kaolin can improve rubber's performance in terms of elasticity, flex resistance, dimensional stability, compression deformation and other properties.

6. Agriculture field:

The kaolin aqueous solution is used in agricultural fields such as fruit trees, grains, vegetables, etc., which can greatly reduce production costs and reduce the amount of pesticide residues in crops.

KAOLIN POWDER MAKING PROCESS 

Kaolin raw material composition analysis table

Selection scheme of main machine for kaolin pulverizing

Remarks: Select the host according to the output and fineness requirements.

1.Crushing of raw materials

The kaolin bulk material is crushed by the crusher to the fineness (15mm-50mm) that can enter the mill.

2. Milling

The crushed small pieces of kaolin are sent to the storage hopper by the elevator, and then sent to the grinding chamber of the mill evenly and quantitatively by the feeder for grinding.

3. Classification

The ground material is classified by the classification system, and the unqualified powder is classified by the classifier and returned to the main engine for re-grinding.

4. 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.
