Magnesium rotary kiln is designed according to dolomite calcination characters and Pidgeon process requirement. That is the key equipment in the calciantion process. The dolomite produced by rotary kiln with stable quality, high activity and low ignition loss that can make higher magnesium extraction rate and silicon utilization rate to save running cost. The rotary kiln is the most suitable equipment for produce magnesium. The new type energy-saving rotary kiln designed by ZK Corp. has own patent and formed dolomite calcination standard for magnesium industry in China. Our products advantages: 1. According to the character of dolomite and its calcination requirement, the structure of kiln inlet and outlet sections has been optimized. It can resolve the problem of material returning back to kiln inlet and the leakage of dust. 2.Inner of the kiln keeps micro negative pressure, dust pollution is lower.
