Regarded as industrial vitamin, rare earth has become a kind of very important strategic resource. Rare earth has been widely applied to petroleum, chemical industry, metallurgy, spinning, ceramics, glass, permanent magnet material and etc. with the development of technology and breakthrough of application technology, the value of rare earth oxide is increasing. In order to meet the demand of metallurgy production and separate rare earth oxide with other mineral materials, rare earth rotary kiln must be applied to the ore dressing and production of rare earth.

As a kind of precious mineral raw materials, rare earth is paid more and more attention. Rare earth has been processed by refinement, calcining, grinding and drying process step by step. Rare earth rotary kiln is a kind of important equipment to calcine rare earth. The final product holds good performance. Henan Dajia Mining Machinery will introduce you the working principle and structure in details.
