Applications:


Building materials industry
Wollastonite powder is a common raw material in the building materials industry. It is mainly used to make architectural materials such as gypsum boards, coatings, and cement. Wollastonite powder has the characteristics of white, delicate, and soft, and can adjust the color and strengthen the hardness and strength of the material in the building materials.

Chemical industry
Wollastonite powder is mainly used in the chemical industry to make silicon-based polymer materials such as silicone rubber and silicone. Wollastonite powder has the characteristics of good heat resistance, corrosion resistance, aging resistance, etc. And can provide good processing performance and use effects for silicon-based polymer materials.

Electronic industry
Wollastonite powder is mainly used in the electronics industry to make electronic materials such as electronic-grade silicon, and alumina alumina. Wollastonite powder has the characteristics of high purity and stability, which can ensure the quality and stability of electronic materials.

The pharmaceutical industry
Wollastonite powder can also be used in the pharmaceutical industry to make inorganic accessories and drug carriers. Wollastonite powder has the characteristics of high purity, acid, and alkali, strong adsorption, etc., and can provide stable quality and efficacy for pharmaceutical products.

Process progress:

Choose raw materials. In the Wollastonite mine, one must choose ore with good quality and stable chemical composition as raw materials.
Gravity processing. Crush raw ore for processing, filtering, etc., and decomposing it into gravel suitable for processing.
Grade and shatter. Use the grinding machine to shatter the gravel to make it a small particle.
Plime processing. Sievage and filtering through the pieces, control the size and ingredients within a certain range.
Drying. Add the powder to the dehydration equipment to remove the water and dry it to achieve a certain degree of drying.
Packing and storage. The powder that has been completed is tested, and then packed according to certain packaging specifications, and stored in the warehouse.

Packing:
Normally, we choose to pack the wollastonite in ton bags, if customers has other requirements, we can also meet them.
