Established in 1956, Henan Zhengzhou Mining Machinery Co., Ltd was a designated factory by Ministry of Machinery Industry and Henan Mechanical & Electronic Bureau to produce equipments for cement, lime and other construction material industries. Supported by Henan Metallurgical Planning & Design Institute and CHALCO Zhengzhou Research Institute, Henan Zhengzhou Mining Machinery Co., Ltd began to develop new product for calcinations of limestone and dolomite in 1988. More than 90% of the domestic Magnesium plants chose our rotary kiln to calcine their dolomite. We also supplied rotary kiln to South Korea’s first Magnesium plant-POSCO M-TECH and the biggest refractory manufacturer in Middle East-KUMAS.
