| Abstract: |
| This paper summarized the research status of Kaolin purification process technology, including the classification equipments, classification processes as well as the magnetic separation technology in the separation system. The necessities to carry out accurate classification for fine particles, and to research and develop dry high gradient magnetic separators are deeply analyzed. Meanwhile, a new grading and separate process applied for the Kaolin purification experiment is proposed via coarse grinding one-time classification fine grinding accurate grading- dry high gradient magnetic separation with conical magnetic medium. |
