The second is active gettering mode. The carding rollers are vertically arranged, the impurity stripping direction is parallel to the horizontal plane, the separation is carried out by means of high negative pressure air flow suction, the effective impurity separation can be carried out on various raw materials with larger impurity content, and the application range is wider.
