Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings.

A pneumatic conveying system with a coarse ash crusher, comprising a crusher body 2, two ends of the crusher body 2 are respectively provided with a gas distribution device 1 and a power device 9, and both sides of the crusher body 2 are provided with strips. The strip-shaped air inlet 4 is provided with a strip-shaped fluidizing plate 3, and both sides of the gas distribution device 1 are provided with a communication pipe 13 that communicates with the strip-shaped air inlet 4. The crusher body 2 is provided with a rotating body 11 driven by the power device 9. The rotating body 11 includes a central shaft 17. The central shaft 17 is provided with not less than one rotating plate 16. There is a rotary cut 15, the inner wall of the crusher body 2 is provided with a fixed plate 10 that cooperates with the rotating plate 16, and the central shaft 17 is provided with a shaft center air inlet 8 that communicates with the gas distributor 1 and is connected with The air distribution chamber 7 communicated with the air inlet hole 8 in the center of the shaft, the central shaft 17 is provided with a circular air inlet hole 5 communicated with the air distribution chamber 7, and the circular air inlet hole 5 is provided with a circular fluidization plate 6.
