The pulverizing sorting implementation process of impact comminution sorting mechanism is as follows:

As Fig. 8 and shown in Figure 9, material is a hopper 24 from pulverizing the sorting mechanism charging aperture, enter the rotor 3 that runs up, feature according to material, the material flow that goes out with the high velocity jet of 40m/s to 120m/s from the inner uniform material channel 28 of rotor 3, evenly spurt into the impact comminution district 8 of annular, and hit on counterattack conical surface 25 and the abrasive material tooth 26, form the work of material hammer impact comminution, under the material flow of ejection drives at a high speed continually, material after the punishment in advance hammer is pulverized, be converted into the high speed circular motion rapidly, under centrifugal action, spiral and climb up along counterattack conical surface 25, pulverize in the district 8 until striking the repercussion that breaks after annular roof plate 20 bounce-backs in district 9 are pulverized in whirling motion, have partial material to move along annular roof plate 20 smaller diameter end, unloaded by the discharging flange 19 vertical with annular roof plate 20, the repercussion that breaks is pulverized in the district 8, the material that the material that breaks is gone out from the follow-up high velocity jet of rotor 3 jets impacts, and realizes that material hits the material impact comminution.Above-mentioned crushing process is called impact comminution.In this process, counterattack conical surface 25 also plays preventing that comminuting matter moist or that hardness is little, granularity is little too much is deposited in impact comminution district 8 except finishing the crushed work of material hammer, in order to avoid influence material hammer crushing effect.Discharging flange 19 can also prevent that material from from 18 discharges of pulse exhaust outlet, reaching solid phase and the centrifugation of gas phase object except playing the discharging effect.

Above-mentioned through the material after the impact comminution, under the material flow and air stream drives of ejection continually, be converted into the high speed circular motion rapidly, counterattack conical surface 25 and with the effect of the acutangulate abrasive material tooth 26 of material movement direction under, the high speed circular motion is done on the material limit, the edge the major diameter side face and is spiraling toward the motion of whirling motion crushing chamber top, this motion process, abrasive material tooth 26 on material and crushing chamber wall and the wall, form crushed works such as frictional impact between material and the material, this process is called whirling motion and pulverizes.Because it is downward opening inversion grooved spaces that district 9 is pulverized in the whirling motion on whirling motion crushing chamber top, after air-flow and material flow are spiraled and are moved to whirling motion crushing chamber top, bump against and break-in with annular roof plate 20 and discharging flange 19, the material repercussion that breaks is pulverized district 8 and is continued to pulverize, air-flow then continues to move in a circle in district 9 is pulverized in whirling motion, continue driving material and move in a circle, the whirling motion air-flow obtains more good utilisation like this, thereby saves the energy.Because the jet of rotor 3 is that a plurality of interval property are uniform, and uniform pulse steam vent 18 also is uniform on the minor diameter side face of whirling motion crushing chamber, material flow and air-flow are done high speed circumference telemechanical in annular whirling motion crushing chamber, a plurality of jet pulsating jet drive and a plurality of pulse steam vent 18 pulsatings release air-flow and pressure along with rotor 3, material flow and air-flow are clocklike pulsed and the whirling motion process, make between material and the material, the bump friction is fierce more between material and inwall and the abrasive material tooth 26, realize quickening to pulverize, improve crush efficiency.This whirling motion process, the whirling motion air-flow carries material and moves in a circle, because centrifugal force is directly proportional with speed, just the airflow rate that pours from jet is faster, its large-diameter region in annular whirling motion chamber moves in a circle, and carry material movement, and through behind one section circular motion, the air-flow limit that energy and speed weaken gradually moves in a circle, the annular space small diameter area of pulverizing district 9 toward whirling motion is squeezed on the limit, speed is more little, the closer to the minor diameter side face, discharges from pulse steam vent 18 at last, the whirling motion air-flow carries material movement, just discharge after speed weakens, make that air-flow and material energy exchange are more abundant, make crushed work energy-efficient from pulse exhaust outlet 18.Cross the airflow reflux path 10 from the air communication that pulse exhaust outlet 18 is discharged, reenter rotor 3, recycling, after quickening, continue to spurt into the whirling motion crushing chamber, continue to participate in crushed work, only have the small part low speed flow to discharge from the discharging opening 6 of pulverizing sorting mechanism, enter next stage and pulverize sorting mechanism, air-flow and energy loss are few.It is very short to discharge 10 paths, air-flow approach return flow line from pulse exhaust outlet 19, and energy loss is few, and it also has than higher rate and enters rotor 3, and this makes rotor 3 quicken these has the reflux airflow of comparison high initial speed degree to be more prone to, thereby reaches energy-conservation purpose.

Material whirling motion crushing process is accompanied by material assorting room as described below, the above-mentioned material of doing the whirling motion pulverizing, in the whirling motion crushing chamber, do in the high speed circumference motion process, produce centrifugal force, it is that the upper end is big that the diameter of the counterattack conical surface 25 in the whirling motion crushing chamber distributes, the lower end is little, material is under centrifugal action, the limit moves in a circle and pulverizes the up climbing of spiraling of edge counterattack conical surface 25 larger diameter end, in the climbing process, little material centrifugal force, momentum is relatively little, and is big by centrifugal force, the big material that momentum is big surmounts or hinders, the pulverizing that moves in a circle on one side of little material, down pushed on one side, more little material is pressed against counterattack conical surface 25 bottoms more, pulverizes on one side big material is done the circumference telemechanical, spiral on one side and climb up, until whirling motion crushing chamber top.Major diameter side face at the whirling motion crushing chamber, be evenly equipped with many from strikeing back the annular top surface 20 that conical surface 25 bottoms extend to the whirling motion crushing chamber, and the abrasive material tooth 26 of curve strip with the protrusion at identical angle of inclination, because abrasive material tooth 26 trends acutangulate with material circular motion direction, material is at high speed circumference motion process, constantly cross each abrasive material tooth 26, each leap all is attended by the process that material up moves along abrasive material tooth 26 slopes, little material centrifugal force is relative with momentum little, by centrifugal force, the big material of momentum surmounts or hinders, after repeatedly crossing over the motion accumulation, little material limit moves in a circle and pulverizes the limit and down pushed, and more little material is pressed against counterattack conical surface 25 bottoms more, big material limit moves in a circle and pulverizes the limit and climb up, continue to pulverize until whirling motion crushing chamber top, material sieves through counterattack conical surface 25 and abrasive material tooth 26 under the action of the centrifugal, finish big material and little material sorting, and separately pulverize.

Material is through after the above-mentioned sorting, little material is extruded on the ring-shaped platform 7 of counterattack conical surface 25 bottoms, continue to move in a circle, material be squeezed power and centrifugal force acting in conjunction, wherein big quality of material is big, its centrifugal force is greater than the material extruding force, move toward ring-shaped platform 7 larger diameter end while moving in a circle, and the centrifugal force of little material is less than the storeroom extruding force, the limit is done the circular motion limit and is squeezed toward the ring-shaped platform smaller diameter end, forced down ring-shaped platform 7 at last, discharged from the discharge gate 6 of mechanism, in this process, material for the dust of dryness lightweight, except major part is taken out according to the method described above, also have the fraction qualified material to follow air-flow and discharge together, this process is called the discharging of material centrifugal screening.

Impact comminution separator for multistage pulverizing sorting mechanism, the material of sorting mechanism is pulverized in above-mentioned discharge, enter next stage and pulverize sorting mechanism, continue the above-mentioned pulverizing sorting work process of circulation, after pulverizing through multistage pulverizing sorting mechanism series connection, comminuting matter is more and more thinner, after afterbody pulverizing sorting mechanism has been pulverized, qualified products enter base 1, and pass through the hopper device for transferring of base 1 bottom, finish whole crushed work.When the vertical closed circuit tandem working of multistage grinder structure, material are pulverized the sorting mechanism discharge from upper level, be accompanied by air-flow and discharge, add the gravity effect, have certain initial velocity and enter rotor 3 that it is easier that this makes that material and air-flow quicken, thereby the load of rotor is alleviated, reach energy-conservation purpose.The tandem working of multistage grinder structure makes upper level mechanism spill a little defective powder, obtains repeating pulverizing, and reaches no screen cloth comminution process.

In production application, when various different materials are pulverized, form, size and hardness according to material are different, by increasing and decreasing counterattack conical surface 25 taperings described above, abrasive material tooth 26 quantity, size and angle of inclination, the size of steam vent 18 and quantity, and at least one of rotating speed of increase and decrease rotor 3, adjustment is from the impact comminution sorting mechanism, take out the granularity of crushed material, under the constant situation of impact comminution sorting mechanism feature and progression, can realize adjusting the granule size that takes out comminuting matter by the rotating speed of increase and decrease rotor 3.

The utility model device structure is simple, spare and accessory parts are few, need not screen cloth, output is big, and energy consumption is low, wide adaptability, according to the feature and the grinding particle size requirement of different material, can be by changing the inner fraction structure of pulverizing chamber, the increase and decrease mechanism sum of series speed of mainshaft gets final product, with as shown in Figure 1 FS500-3 type is example, it is the series connection of three grades of pulverizing sorting mechanisms, and root diameter is 500mm, and outfit power is 55KW, in potato starch industry, when pulverizing fresh living potato, production capacity reaches 25T/H, and is suitable with the flyball formula pulverizer output that is equipped with 90KW, but its slag of pulverizing out slurry granularity is thinner, has only 1/2nd of flyball formula grinding particle size.In the crushed work of dried cassava slice, its output reaches 20T/H, and is suitable with the flyball formula pulverizer output that is equipped with 90KW, but its tapioca starch fineness ratio flyball formula pulverizer of pulverizing out is thin 3 times, and 100 eye mesh screen percent of pass reach about 95%.In the ore crushed work, as raw material, output reaches 15T/H with the lime stone fine sand of 2～3 commonly used mm particle sizes of foundry industry (granularity be 2 to 4MM), and product granularity reaches centimillimetre Cmm level.
