Meanwhile, in the process that the gas entering the fourth cavity 16 through the second air inlet pipe 4 and the material entering the fourth cavity 16 through the circulation channel 6 fully act and move upwards, the diameter of the fourth cavity 16 is continuously enlarged, so that the speed of upward air flow is reduced, large particles carried by the upward air flow can flow towards the side wall and flow back downwards to form a ring core structure, and when the large particles flow downwards near the second air inlet pipe 4 at the near wall end, the large particles are sucked again into a crushing area formed by the gas entering the fourth cavity 16 through the second air inlet pipe 4, so that the large particles are crushed continuously.
