And an air induction channel 2032 extends through the periphery of the conical dispersion member 203.
The existing particle separator has relatively poor separation effect, the size of particles obtained after separation is not uniform enough, powder is mixed between the particles, and the cleanness degree is relatively low. And through toper dispersion subassembly 203 in this scheme, the material flows in the intracavity after, because the effect of toper piece, material flows and is umbelliform separation flow to the realization is shunted the material that 13 bearing platforms air feed passageways of feed inlet flowed in, prevents that the material from blockking up.
Meanwhile, the air supply channel is arranged in the inner cavity 202, the air supply direction of the air supply channel is opposite to the flowing direction of the materials in the flow dividing channel, and the powder and part of fine particles in the animal material particles are floated up to separate from the material flow through the wind with the feeding direction opposite to the particle conveying direction, so that the effect of removing the light powder and the non-fine particles is achieved, the powder cannot be mixed between the particles obtained through discharging, and the cleanness degree of the obtained materials is high.
And through the air inducing channel 2032, air can contact with the material again when entering the diversion flow channel from the air inducing channel 2032, so that the contact time of the air flow penetrating the particle material layer is increased, and the air separation effect is further improved.

To remain stationary, the sidewall of the cross flow plate is connected to the inner wall of the cavity 202. The conical dispersing assembly 203 is matched with the separating assembly to form secondary separation, so that fine particles are removed, the separation effect is improved, and the uniformity of the particles after discharging is improved.
As a better implementation mode, the size of the through hole on the cross flow plate is 8-15 mm different from that of the sundries screening and discharging conveyor. The cross flow plate is arranged in an inverted cone shape, materials scattered around the plate surface of the cross flow plate can slide down by gravity and pass through the through holes, meanwhile, reverse wind flows in the through holes and the cross flow channel in a reverse direction, so that fine particles are prevented from sliding down, and further fine particles and light powder are winnowed. Only the particles with larger particle size can pass through the through holes, but the size of the through holes is limited to be different from 8-15 mm of the screening sundry discharging conveyor, and only the particles with the size of 8-15 mm of the screening sundry discharging conveyor can pass through the through holes, so that the uniform and consistent particle size after discharging is ensured.
