Jiangxi Huaming Nanometer Calcium Carbonate Company Limited is a joint venture, whose capital is originated from Yinggangling Mining Bureau and Shanghai Huaming Hi-Tech (Group) Co., Ltd & National Engineering Research Center of Ultrafine Powder, mainly manufacturing nanometer calcium carbonate. And the main products include series of nanometer, sub-nanometer level ultrafine active calcium carbonate for rubber, plastics, coating, adhesive and ink application. The first period of the project occupies 52,000 square meters and a 40,000-ton annual production of nanometer, sub-nanometer level ultrafine active calcium carbonate has been put into production .

The production base of the company is situated at the Jianshan Town at the common boundary of Gaoan City, Xinyu City and Zhangshu City, where the special railway joints Zhegan Railway Line in Zhangjiashan Railway Station. The sub-branch of the road joints 320 national road, and Hurui and Ganyue highway run across. It indeed has a very convenient traffic system.

Depending on the advantage of raw material from the production base and the advantage of technology from National Engineering Research Center of Ultrafine Powder, the company manufactures ultrafine active calcium carbonate, which has excellent functionality with small size, stable crystal, narrow size distribution, and good dispersity. It can be widely applied in the fields like rubber, plastics, coating, adhesive, ink etc. The company pioneers in applying technologies like gas-burning kiln, static drying in the line in China, and achieves some features, such as high purify, good dispersity, which are obviously superior to traditional products. These technologies thoroughly eliminate black spots and impurities in the product and thus make the performance index of the product internationally first-class.
