mica powder loading

What cannot be ignored is that the leakage of goods in the logistics process may have a very bad impact on the environment.


Generally, users in Japan and Singapore are particularly sensitive to the pollution on the packaging surface. We have taken very effective measures to avoid shoe prints or similar problems that are difficult to eradicate on our goods.


We also pay special attention to the quality of materials and auxiliary materials. In order to prevent mildew, we choose dry pallets and strictly test the shipment of each batch.


We insist on using experienced and skilled workers to train our special operation requirements and techniques to ensure a high degree of unity in each delivery.

Advanced equipment for producing wollastonite powder

We produce dense powder and needle shaped powder separately, completely separate the process and equipment, and carry out targeted technical upgrading to make them better in the application of their respective subdivided fields.

The key to ensure the quality is to keep consistent with the testing of users. Our testing methods and equipment have been assisted by long-term users, so that the testing results of each batch are always consistent with all users.

We have just replaced the air compressor with Swedish equipment, and optimized the production process of the equipment and air mill based on many years of experience to ensure high whiteness even in wet environment in rainy season.

Over the past 30 years, we have always insisted on using air flow grinding from Germany to produce products with stable quality, which has always been in a dominant position at the level of ultra-fine powder.
