But in the existing slag micropowder production equipment; Being used for that the slag material is carried out the roller type vertical mill of grinding can not be disposable all levigate with slag; Some slag is by the levigate mill that just is thrown out of, and needs artificially this part coarse fodder collected to send into Vertical Mill once more and carry out grinding, wastes time and energy; And the abrasive grit in the slag is entrained in and is not recovered use in the coarse fodder, wasted resource.
Summary of the invention
The utility model technical problem to be solved is: a kind of coarse fodder that slag micropowder uses device of refacing of producing is provided; The coarse fodder circulation that produces in the grinding process is sent into Vertical Mill and is refaced, and grinding is thorough, and time saving and energy saving; And in coarse fodder circulation material conveying process, reclaim abrasive grit, made full use of resource.
For solving the problems of the technologies described above; The technical scheme of the utility model is: produce coarse fodder that slag micropowder the uses device of refacing, comprise roller type vertical mill, be connected to star-like feeder at the charging aperture uplink of said roller type vertical mill; Be provided with powder concentrator in the connection of the top of said roller type vertical mill, wherein:
Be provided with the coarse fodder blanking port in the bottom of said roller type vertical mill, being connected at said coarse fodder blanking port place has the feed back belt feeder;
Blanking end linking at said feed back belt feeder has bucket elevator;
Outlet linking at said bucket elevator has the circulation feed bin;
Being connected in the outlet of said circulation feed bin has tramp iron separator, and being connected in the abrasive grit outlet of said tramp iron separator has the abrasive grit feed bin; Material outlet linking at said tramp iron separator has the feed belt machine, and the blanking end of said feed belt machine is connected with the import of said star-like feeder.
As a kind of optimized technical scheme, be equipped with cleaning shaft in the exit of the top of said circulation feed bin, said circulation feed bin and the material outlet place of said tramp iron separator, the outlet of said cleaning shaft is connected with deduster.
After having adopted technique scheme; The beneficial effect of the utility model is: owing in the linking of the coarse fodder blanking port place of roller type vertical mill the feed back belt feeder is set; The blanking end of feed back belt feeder is connected has elevator; The outlet of elevator is connected the circulation feed bin, and the outlet of circulation feed bin is connected tramp iron separator, and the abrasive grit outlet of tramp iron separator is connected with the abrasive grit feed bin, material outlet is connected with the star-like feeder of roller type vertical mill import through the feed belt machine.Therefore; After the slag material gets into roller type vertical mill through star-like feeder; Rolled by mill and grinding roller; And under the mill action of centrifugal force, be thrown to the mill edge, and be vane around the mill edge, hot blast gets into roller type vertical mill through hot air duct from the vane around the mill levigate slag powders is taken in the powder concentrator of Vertical Mill top; The bottom that does not have levigate slag and the abrasive grit in the slag then to fall roller type vertical mill through vane; Through scraper plate they are collected, seen off by the coarse fodder blanking port, process feed back belt feeder and bucket elevator are mentioned the circulation feed bin of eminence then; Coarse fodder and abrasive grit come out from the circulation feed bin; Through behind the tramp iron separator, abrasive grit is selected and collects the abrasive grit feed bin, is transported then; Coarse fodder is then fallen on the feed belt machine, gets into roller type vertical mill once more through star-like feeder and carries out grinding.In sum, the utility model is sent the coarse fodder circulation that produces in the grinding process into Vertical Mill and is refaced, and grinding is thorough, and time saving and energy saving, and in coarse fodder circulation material conveying process, reclaims abrasive grit, has made full use of resource.
