Link；The airslide disintegrating mill after filtration drying, spurts into crushing chamber by Laval nozzle high speed, in multiply in compressed air
At the joint of high pressure draught material by impact several times, friction, shearing and crush, smashed material blower draft effect under
Graded region is moved to ascending air, under the powerful centrifugal force effect that high-speed rotating stage turbine generates, makes thickness material
Separation, the fine grained for meeting granularity requirements enters cyclone separator by grading wheel and deduster is collected, and coarse granule drops to powder
Continue to crush in broken area；The fine grained for meeting granularity requirements enters dust separator by dedusting separating opening；Dust separator is equipped with
Filter screen, the dust with particle falls the particle of the inside by filter screen filtration, to prevent particle to be brought into atmosphere, to environment
Secondary pollution is caused, the particle filtered out, which precipitates, becomes the coal dust crushed.
A kind of crushing machine provided by the invention passes through the portions such as setting blower, compressed air shotblasting machine, airslide disintegrating mill, dust separator
Part；Have the advantages that high production efficiency, product granularity are uniform, cost is inexpensive.
Detailed description of the invention
Fig. 1 is the top view of crushing machine (being free of dust separator) provided in an embodiment of the present invention.
Fig. 2 is the side view of crushing machine (being free of dust separator) provided in an embodiment of the present invention.
Fig. 3 is the perspective view of the dust separator provided in an embodiment of the present invention for crushing machine.
Specific embodiment
The present invention is further illustrated in the following with reference to the drawings and specific embodiments.
Unlike the prior art, crushing machine provided in an embodiment of the present invention crush and separate every time cutting simultaneously into
Row, when being exactly primary crush, the coal dust separated in synchronization met the requirements is gone out, then the close particle of granularity is carried out a thin wheat-middlings
It is broken.This technology, without any idle labour, saves certainly due to going out to the coal dust separated in synchronization for having reached fineness requirement
Can, meanwhile, not up to desired particle, it will be collected according to grain size intervals after each crush and carry out next crushing, imitate energy utilization
Rate, crushes speed, and Energy in use is all greatly optimized.
The crushing mechanism that airslide disintegrating mill is primarily adapted for use in determines the features such as its is applied widely, finish fineness is high, leads to
It crosses and the normal air of gas source part is changed to the inert gases such as nitrogen, carbon dioxide gas, the machine can be made to protect as inert gas
Equipment is protected, the crushing and classification suitable for the materials such as inflammable and explosive, oxidizable is processed.
Airslide disintegrating mill and cyclone separator, deduster, air-introduced machine form a whole set of crushing system.Compressed air is through filtering
After drying, by Laval nozzle high speed spurt into crushing chamber, at the joint of multiply high pressure draught material by impact several times,
Friction is sheared and is crushed, and smashed material moves to graded region with ascending air under blower draft effect, in high speed rotation
Stage turbine generate powerful centrifugal force effect under, make thickness feed separation, the fine grained for meeting granularity requirements passes through classification
Wheel enters cyclone separator and deduster is collected, and coarse granule, which drops to disintegrating area, to be continued to crush.
Compressed air shotblasting machine is also sand-blasting machine, sander.Its principle is directly to be got to sand material (ball) using the compressed air of high speed
Workpiece surface, so that workpiece surface be made to generate variation.
As shown in Figure 1-3, crushing machine provided in an embodiment of the present invention, including blower, in crushing process, blower will be general
Blowing air is sent into；Sand ball is directly got to coal cinder surface to be comminuted using the compressed air of high speed, made to powder by compressed air shotblasting machine, compressed air shotblasting machine
Broken coal block surface generates variation, and enters next working link by scraping pole collection port；Airslide disintegrating mill, compressed air warp
After filtration drying, crushing chamber is spurted by Laval nozzle high speed, material is by repeatedly at the joint of multiply high pressure draught
Collision, is sheared and is crushed at friction, and smashed material moves to graded region with ascending air under blower draft effect, in height
Under the powerful centrifugal force effect that the stage turbine of speed rotation generates, make thickness feed separation, the fine grained for meeting granularity requirements is logical
It crosses grading wheel and enters cyclone separator and deduster collection, coarse granule, which drops to disintegrating area, to be continued to crush；Dust separator meets
The fine grained of granularity requirements enters dust separator by dedusting separating opening, and dust separator is equipped with filter screen, the powder with particle
Dirt causes secondary pollution to environment so that particle be prevented to be brought into atmosphere by the particle that filter screen filtration falls the inside, filters
The particle fallen, which precipitates, becomes the coal dust crushed.
Using above-described crushing machine, crushes every time and separation is cut while being carried out, when being exactly primary crush, meet
It is required that coal dust separated in synchronization go out, then the close particle of granularity is subjected to thin primary crush.Due to wanting to having reached fineness
The coal dust separated in synchronization asked is gone out, certainly energy saving without any idle labour, meanwhile, not up to desired after each crushing
Grain is collected according to grain size intervals and carries out next crushing, make energy utilization efficiency, crushes speed, and Energy in use is all greatly optimized.
Using above-described crushing machine, crush efficiency is high, easily implements, at low cost.The product granularity of production is uniformly, carefully
Degree is controllable, can form 50t/h as needed to 500t/h series of products, crush the coal dust that machine crushes, will make coal gasification, coalification
Work efficiency rate greatly improves, and previous carbon yield is made to drop to 1-5% by 10-20%, makes to subtract using the catalyst amount of catalysis technique
Few 30-50%, makes coal dust electricity power enterprise that cost be greatly reduced, and creates immense value for enterprise.It should be noted that of the invention
Machine is crushed, unclassified stores can also be crushed, this will not be repeated here.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than limitation of the present invention, this field it is common
Technical staff is regarded as falling into protection scope of the present invention to the simple modification of its technical characteristic carried out or equivalent replacement.
