The induced draft pipe 8 is connected with an induced draft port of an induced draft fan or a dust collector to actively induce air. Because the induced draft mouth draws a large amount of air away, cause the material cavity 10 in to produce the negative pressure. The negative pressure environment of the discharge chamber 10 causes the air of the crushing chamber 2 and the main shaft chamber 5 to flow towards the discharge chamber 10. After the air supply opening 7 is opened, a large amount of outside air gushes into the discharging cavity 10 to form strong air flow flowing from the air supply opening 7 to the air induction opening, and the strong air flow can take away a large amount of micro particles to realize the micro particle grading function.

In practical application, air entering the inlet and the outlet is reduced as much as possible, but this is unavoidable, and in addition, the air entering the inlet is wrapped with the material and enters the machine body, so that the air entering the inlet and the outlet can only be properly controlled. The utility model discloses formed and used induced duct 8 as only air outlet, feed inlet and mending wind mouth 7 are main air inlet, go out the air access that the feed cylinder is supplementary air inlet. The material in the discharge chamber 10 flows in the opposite direction to the air, which in turn produces scrubbing and particle separation of the material particles.

The scrubbing and separating functions of the parts exist at the same time, air is wrapped with the tiny particles and flows into the air inlet together, and the tiny particles are finally discharged, so that the effect of grading the tiny particles while crushing is realized.
