The working process of the present embodiment is:
The rotor 2-1 high speed rotating of high force dispersion parts, the material cake rolled by roll squeezer fed by opening for feed 1-1 carries out high force dispersion, the classification field of force that parabolic motion is formed done through screening the air-flow of the nozzle 3-1 ejection of device by strength by material after dispersion, the effect that material is subject to air-flow in the classification field of force moves downward, as shown in Figure 4, grain graininess sequence is different material grain graininess running orbit: d1 < d2 < d3 < d4 < d5 < d6 < d7.
The acceleration that the power that particle is subject to produces is relevant with the quality of particle, grain graininess is more little, the acceleration produced is more big, the acceleration of the more big generation of grain graininess is more little, therefore material (the d1 of minimum particle, d2, d3) just can depart from point favored area at sorting rotor 4-1 place that original orbit enters flotation-dividing part and carry out sorting and granularity is more little more be introduced into sorting rotor 4-1 region, finished product is discharged by product outlet 1-2 by sorting rotor 4-1, the particle not meeting finished product requirement is then collected by entering grind materials outlet 1-3 discharge by entering grind materials rewinding heavy curtain 6-1 under sorting rotor 4-1 effect, the particle (d4, d5) that granularity is bigger is subject to less acceleration action, can by the classification field of force and by entering grind materials rewinding heavy curtain 6-1 collection by entering grind materials outlet 1-3 discharge, the particle (d6, d7) of volume particle size is then subject to very little acceleration action, directly pass the classification field of force and cross the regulating fender 5-1 of work in-process adjustment component, return material rewinding heavy curtain 6-2 collection by roll squeezer and return material outlet 1-4 discharge by roll squeezer.
When needing two kinds of methods can be adopted to realize when the material amount entering grind materials outlet 1-3 production being adjusted:
Method 1, strength can be increased screening device nozzle 3-1 provide quantity of airflow to increase the classification field of force, bigger material is made to enter the capture range into grind materials rewinding heavy curtain 6-1 under the effect in the classification field of force and export 1-3 discharge by entering grind materials, thus it being added to mill product production, the median size simultaneously producing material will increase; The quantity of airflow that can provide by reducing the nozzle 3-1 of strength screening device is to weaken the classification field of force, less material is made to enter the capture range into grind materials rewinding heavy curtain 6-1 under the effect in the classification field of force and export 1-3 discharge by entering grind materials, thus reducing into mill product production, the median size simultaneously producing material will reduce.
Method 2, can adjust, by adjusting the height of regulating fender 5-1 of work in-process adjustment component, the material amount exporting 1-3 and producing into grind materials, when the height of the regulating fender 5-1 of work in-process adjustment component rises, the active area entering grind materials rewinding heavy curtain 6-1 increases, grind materials outlet 1-3 discharges by entering can to absorb more material, thus it being added to mill product production, the median size simultaneously producing material will increase; When the height of the regulating fender 5-1 of work in-process adjustment component declines, the active area entering grind materials rewinding heavy curtain 6-1 reduces, grind materials outlet 1-3 discharges by entering can only to absorb less material, thus reduces into mill product production, and the median size simultaneously producing material will reduce.
The product grading that product outlet 1-2 in the present embodiment produces is determined by the rotating speed of rotor 2-1, can increase rotor 2-1 rotating speed when the product granularity needed diminishes; Rotor 2-1 rotating speed can be reduced when the product granularity needed becomes big. The finished product quantity that product outlet 1-2 produces then is decided by the performance of milling of roll squeezer, due to the rotor 2-1 high speed rotating of high force dispersion parts, the material cake rolled by roll squeezer fed by opening for feed 1-1 carries out high force dispersion, material cake is by after powerful sorting, under fine particle screens the classification force field of the air-flow formation of the nozzle 3-1 ejection of device in strength, can all enter sorting rotor 4-1 and carry out sorting, avoid the material reaching finish fineness enter grinding machine carry out again powder mill cause material cross powder mill. If during fine powder content height in roll squeezer product, the finished product quantity that product outlet 1-2 produces will be many, if when the fine powder content in roll squeezer product is low, the finished product quantity that product outlet 1-2 produces will be less. Due to material dispersity height, the nozzle 3-1 of strength screening device only needs less airshed namely can complete the sorting of finished product and the acceleration of relatively coarse particles, system only needs a configuration less recirculation blower, it is possible to the effective electricity consumption reducing system fluid flowing and consuming.
Owing to material cake disperses by the rotor 2-1 high speed rotating of high force dispersion parts, dispersion efficiency height, so the compact equipment of the present invention, device height is low; This equipment is installed in roll squeezer system the height taken and volume all smaller, the total height of roller press grinding system can be effectively reduced, thus reduce the height of lift technique in system capital construction cost and system, the power consumed for the circularly enhancing of material in the process of system cloud gray model can much slower, thus effectively reduce system electricity consumption.
In addition to the implementation, the present invention can also have other enforcement modes. All employings are equal to replacement or the technical scheme of equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
Part that the present invention does not relate to is all same as the prior art or adopts prior art to be realized.
