Mining & Aggregate Screening Solutions | DUNPAI

About DUNPAI

Founded in 1973 as a state-owned enterprise known as Shanghai Qianshao Mining Screening Factory, DUNPAI has evolved into a leading manufacturer of screening solutions for mining and aggregate industries.

In 1985, we entered the iron and steel industry, and our screens soon replaced imported products in key applications. After restructuring into a joint-venture in 1998, we expanded our capabilities and now serve global industry leaders including Terex, Metso, Sandvik, and Baosteel Group.
