One grading plant can be filtered through the bigger material of particle, the discharging opening connection drying of the prilling granulator compared with the second grading plant
The charging aperture of device, the feeding mouth of the discharging opening connection corase grind pulverizer of drying device, roughly grinds the discharging opening connection the of pulverizer
One grading plant, the material being filtered through by first grading plant enters the second grading plant, it is impossible to by first point
The material of stage arrangement filtering returns to corase grind pulverizer and is crushed again, and the material filtered by the second grading plant enters
Qualified storehouse, it is impossible to crushed into fine grinding pulverizer by the material of the second grading plant, the thing after the crushing of fine grinding pulverizer
Material is again introduced into the second grading plant and carries out screen filtration, and certified products enter qualified storehouse.
Preferably, the particle diameter of first grading plant filtering is less than 5mm, the second grading plant filtering
Grain diameter is less than 1mm.
Preferably, more than one group of scraper is included in described fine grinding pulverizer, scraper connects the master of fine grinding pulverizer
Axle, scraper is adjacent to fine grinding and crushes pusher side wall and be rotated by main shaft.
Preferably, connected by pressure cylinder between the scraper and main shaft.
Preferably, the pressure cylinder periphery is cased with protective cover.
The utility model has the advantages that：
The utility model is classified by two parts level machine for setting, and can separate the material in two kinds of specification limits, if
Corase grind pulverizer and fine grinding pulverizer are equipped with, the thicker material for filtering out directly returns corase grind pulverizer and crushed, more carefully
Material be directly entered fine grinding pulverizer and carry out attrition grinding so that pulverizer can more targetedly to correspondingly sized
Material is ground, and substantially increases the efficiency of grinding, and the effect of grinding is more preferable.Meanwhile, be increased on fine grinding pulverizer and scraped
Knife, can constantly the material being bonded on fine grinding pulverizer sidepiece, so as to ensure that the space of crushing, it is ensured that the efficiency of crushing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of fine grinding pulverizer.
In figure：1- prilling granulators, 2- drying devices, 3- corase grind pulverizers, the grading plants of 4- first, the classification dresses of 5- second
Put, 6- fine grinding pulverizers, the qualified storehouses of 7-, 61- main shafts, 62- scrapers, 63- pressure cylinders, 64- protective covers.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model will be further described：
Reference picture 1, a kind of dry method pulverized coal preparation system, including prilling granulator 1, drying device 2, corase grind pulverizer 3, first are classified
Device 4, the second grading plant 5, fine grinding pulverizer 6 and qualified storehouse 7, first grading plant 4 can mistakes compared with the second grading plant 5
By the bigger material of particle, the discharging opening of the prilling granulator 1 connects the charging aperture of drying device 2 for filter, and drying device 2 goes out
The feeding mouth of material mouth connection corase grind pulverizer 3, the discharging opening for roughly grinding pulverizer 3 connects the first grading plant 4, by described first
The material that grading plant 4 is filtered through enter the second grading plant 5, it is impossible to by the first grading plant 4 filter material again
Return to corase grind pulverizer 3 to be crushed again, the material filtered by the second grading plant 5 enters qualified storehouse, it is impossible to by the
The material of two grading plants 5 is crushed into fine grinding pulverizer 6, and the material after fine grinding pulverizer 6 is crushed is again introduced into second
Classification fills 5 and puts is filtered, and certified products enter qualified storehouse.
Specifically, the particle diameter of first grading plant 4 filtering is 5mm, the filtering of the second grading plant 5
The a diameter of 1mm of grain, material of first grading plant 4 particle diameter more than 5mm is returned directly to corase grind pulverizer 3 and carries out powder
It is broken, and it is also to be specifically used to the larger material of pulverized particles to roughly grind pulverizer 3, the second grading plant 5 is 1- particle diameter
The material of 5mm returns to fine grinding pulverizer 6 and is crushed, and fine grinding pulverizer 6 is directed to what the material of relatively fine particle was ground,
Targetedly, grinding efficiency is higher.
In addition, reference picture 2, includes more than one group of scraper 62, the connection fine grinding of scraper 62 in described fine grinding pulverizer 6
The motor-driven main shaft 61 of pulverizer 6, the side wall of fine grinding pulverizer 6 is smooth, and scraper 62 is adjacent to the side wall of fine grinding pulverizer 6 and by leading
