Central part at crushing chamber 10, with this air stream be pulled into that the attraction that attracts fan 24 causes, from raw material input port 4 towards the axial air stream of crushed material conveying end 7, row is to the spiral air flow E of the cyclone shape of air intake duct 6 when consequently, being created in rotation at a high speed.

Also have, stir pulverize with blade 12 with stir divide select for use blade 14 near, respectively in the outside of spiral air flow E, the centrifugal flow F of generation outside radial direction, G.

Driving attraction fan 24 and rotor rotating shaft 11, after its rotation status is stable,, raw materials such as soybean are dropped into crushing chamber 10 inside from raw material input port 4.

Here, also can be from former hopper etc. to the supply of the raw material of raw material input port 4, carry out while adjust the opening degree plus-minus quantity delivered of baffle plate, still, in order more correctly to control the quantity delivered of raw material, preferably adopt feed mechanisms such as screw feeder, vibrating feeder to carry out.

The raw material H that puts into crushing chamber 10 inside from raw material input port 4 is carried by the air stream that produces because of the attraction that attracts fan 24, is drawn among the crushed zone J of inside of the pulverizing chamber 2 that is formed at crushing chamber 10.

The raw material H that invades among the J of this crushed zone at first collides with the edge part that the stirring of rotation is at high speed pulverized with blade 12, is pulverized the particle into size.Then, the trickle crushed material of a part that produced this moment is carried by spiral air flow E, directly transports to the branch favored area K of the inside of the separation chamber 8 that is formed at the next-door neighbour.

Because it is still thicker to transport to the granularity of particle of most raw material of crushed zone J, quality is also bigger, so it is in J inside, crushed zone, move towards radial outside, under the assistance of centrifugal flow F, stir, by the collision between the particle, or the collision of the inner peripheral surface of particle and pulverizing chamber 2, further it is ground into more tiny particle.

Like this because the action of centrifugal force of the particle that attenuates of granularity is less than the thicker particle of granularity, so this particle towards the central part side shifting of crushed zone J, E captures by spiral air flow, moves towards a minute favored area K.

Because this moment, the crushed material of raw material H around the central axis rotation of crushing chamber 10, advances under the effect of spiral air flow E simultaneously, so under action of centrifugal force, the thicker particle in the crushed material moves at radial outside, thinner particle moves at radially inner side.

If these crushed materials invade among the branch favored area K, then owing to the effect of selecting blade 14 for use here because of the stirring branch that rotates at high speed, the rotary speed of spiral air flow E is increased, simultaneously, produce centrifugal flow G in its outside, so from the crushed material that crushed zone J sends into, the thicker crushed material of granularity is subjected to action of centrifugal force, and towards the outer side shifting of spiral air flow E, G captures for centrifugal flow, its part is stirred by centrifugal flow G, is ground into trickleer particle.

If centrifugal flow G collision divides the inner peripheral surface 37 of the truncated cone shape of favored area K, then here along the incline direction of above-mentioned inner peripheral surface 37, change to discrete areas J towards, follow this situation, thicker crushed material also is back to crushed zone J, here pulverizes once more to be trickleer particle.

The crushed material of sending into the thinner crushed material of branch favored area K and being pulverized by centrifugal flow G is carried by spiral air flow E, and from crushed material conveying end 7, row in the tight the place ahead that attracts fan 24, is captured by bag hose 23 in the way to suction tube 6, takes out by revolving valve 56.

In addition, with soybean, grain dusts such as rice are broken into the occasion of the fine particle shape about 10 microns, chemical analysis by the applicant, if adopt the raw material that has agricultural chemicals at soybean, rice, it is ground into fine particle shape about 10 microns, and then the content of agricultural chemicals is 0, can be with pesticides removal.

That is, can think that by being ground into the fine particle shape about 10 microns, Pesticide Molecule is destroyed, thereby with its removal.

Also have, owing to have rotor segment, so can automatically scrape the raw material that is attached on the crushing chamber inwall.

Consequently, owing to, can prevent from the rotation of stirring grinding rotor and stirring sorting rotor is counteracted,, keep in repair easily so can need not the maintenance of short-term by raw material being piled up in the crushing chamber inwall.

Have, the bight of crushing chamber inwall and protuberance are formed by the smooth surface of concave arc shape or dome arcuation respectively again, thereby can make the raw material of having pulverized be difficult to be attached on the inwall of crushing chamber 10.

In addition, because whole crushing chamber inwall is carried out minute surface fine finishining, so the raw material of having pulverized is difficult to be attached on the inwall.

In addition, can pass through common drive source, carry out the pulverization process of the raw material of a pair of crushing chamber, and can in two crushing chambers, handle simultaneously similar or inhomogeneous raw material, can smaller volume, low price ground forms the high pulverizing separator of treatment effeciency.
