The working principle and the process of the utility model are as follows: the crusher 21, the blower 25, the induced draft fan 31 and the motor 33 are started. At this time, the wind blown by the blower 25 travels inside the inlet pipe 24 toward the outlet of the inlet pipe 24 in the cylinder. External air is introduced into the induced draft fan 31 and is delivered into the barrel from the upper material output part 11 through the induced draft pipe 32, the introduced air generates rotational flow movement under the action of the impeller 34 to form rotational flow, the air outside the rotational flow moves downwards to form external vortex, and the air at the center of the rotational flow moves upwards to form internal vortex.

The base plate of the circuit board to be processed is placed into the crusher 21, the material crushed by the crusher 21 falls into the vibrating screen 22, the vibrating screen 22 screens the material, the material with the particle size meeting the design requirement falls into one end of the input pipe 24 through the vibrating screen 22, the material which cannot pass through the vibrating screen 22 and stays on the surface of the material slides into the recovery part 23 through the screen surface of the inclined vibrating screen 22, the material in the recovery part 23 is periodically recovered, and the material is placed into the crusher 21 for further crushing.

The material falling into the input pipe 24 is driven by the wind blown by the blower 25 to move along the input pipe 24, and then flows out from the outlet end of the input pipe 24 and enters the inside of the cylinder, and the material flowing out from the outlet end of the input pipe 24 is blocked by the material cover 27 and cannot continuously rise in the inside of the cylinder, but moves around the material cover 27.

After the material got into the barrel, under the effect of outer vortex and interior vortex, because metal particle weight is greater than nonmetal granule weight, metal particle is driven downstream by outer vortex, get into down material output 16 behind material input part 14 and funnel portion 15 in proper order, slide down along the "slope" of material output 16 down, fall into down material collection device from export 17, nonmetal granule that the weight is relatively little is driven upward movement by interior vortex, material output pipe 41 on getting into through last material delivery outlet on material output 11, nonmetal granule falls into material collection device 42 under the effect of gravity after being blockked by filter screen 43, the dirty gas of passing through filter screen 43 sends into dust collector 5 and removes dust.

In the above process, under the action of the blast air and the swirling air of the blower 25, part of the metal particles are brought into the guide part 13, and since the inner diameter of the guide part 13 is increased from top to bottom and then decreased, that is, the inner wall of the guide part 13 protrudes outwards, the blocking and guiding effects on the part of the large particles and the metal particles are formed, so that the large particles and the metal particles move downwards.

Preferably, the diameter of the material particles entering the input pipe 24 through the vibrating screen 22 is 0.6mm to 0.1 mm.
