Zhengyuan Powder R&D Co., Ltd. is located in industrial park of nanhui district of Shanghai city, is a national key scientific and technological enterprise. We integrate designing and developing with manufacturing, equipped with kinds of powder engineering facilities for superfine grinding and classifying of materials, as the Ultrafine Grinding Mechanical Engineering Research Center of Shandong City.

Consisting of development center, trial center, fabrication center and inspection center and seven departments, Zhengyuan has the assets of RMB50,000,000, covering an area of 46,000 square meters. There are six high standard workshops used for production and trial. The topping trial plant is equipped with 52 types of equipment and a laboratory assembled with the Malvern Mastersizer 2000 and all kinds of advanced testing instruments, convenient for our customers' free industrial grinding or classifying trial at any time. With the complete process equipment, we can independently fabricate most of the equipment components except for foundry goods, so the quality of our equipment is guaranteed.

Our top products such as Cyclonic Jet Mill, Superfine Self-diffluent Classifier, Superfine Mechanical Pulverizer and Superfine Classifying Ball Mill have been ranked among the national key scientific and technological projects. These facilities have been widely used in traditional fields such as non-metallic minerals, chemical engineering, electron, pharmacy, paper-making, high hardness material, pigment, metal material, food, composite material, abrasives, solar material, new building material, fine ceramic material, magnetic material and new metallic material. Our products sell well in the whole country and have been exported to Britain, Spain, India, France, Vietnam and Russia.

We will continue to rely on the strength of new product developing with a great effort in the field of powdery engineering.
