In this embodiment, the heights of all the material passing channels 06 decrease from the axis of the centrifugal turntable to the periphery of the centrifugal turntable in sequence, as shown in fig. 2. The height of the material passing channel 06 is set to be reduced in sequence, so that the fiber material can enter the next centrifugal unit 05 after being blasted to reach a certain small bundle diameter in each centrifugal unit 05, and the layering arrangement is favorable for improving the proportion of the small bundle diameter fiber bundles.

In this embodiment, the driving shaft 02 is vertically disposed, and the centrifugal turntable is disposed at the upper end of the driving shaft 02. The feeding and discharging operation is convenient.
