Fig. 2 is the utility model structure side view schematic diagram.
The specific embodiment
Further specify the specific embodiment of the present utility model below in conjunction with accompanying drawing.
Ore beater grinder with circulated wind and adjustable fineness of the present utility model, comprise charging aperture 14, blower fan 1, air channel 2, hammer crushing device 3, lingering remnants of past customs pipe 12, breeze grading plant 8, breeze passage 5, cyclone separator 9, discharging opening 11, it is characterized in that, open-close type fineness adjusting device is set on the breeze passage 5 between described breeze grading plant 8 and the hammer crushing device 3, the classification rotor 6 that outlet air end outside band aerofoil 7 is arranged in the described breeze grading plant 8, establish classification chamber 15 in this classification rotor 6, sidewall is established rotor hole 16.
Described open-close type fineness adjusting device is by being located at breeze access opening 13 on described breeze passage 5 sidewalls, covering on each breeze access opening 13 and regulate valve block 4 with the fineness that fineness control valve adjusting knob 10 is rotationally connected and form.
Described breeze access opening 13 and fineness are regulated valve block 4 and vertically are symmetrical arranged the 2-6 row, and every row 1-6 is right.
Described fineness is regulated valve block 4 can center on fineness control valve adjusting knob 10 sidespin turnback outside.
Described rotor hole 16 evenly is provided with at classification rotor 6 sidewalls, diameter 10-50 millimeter, and quantity is 100-1000.
Described aerofoil 7 is evenly distributed along classification rotor 6 outlet air end outer circumference, is 4-12.
During the system breeze, the lump of handling is dropped into charging aperture 14, pulverize, form breeze through hammer crushing system 3, wind blows out from blower fan 1, by air channel 2, enters breeze access opening 13, breeze is upwards promoted,, enter and enter cyclone separator 9 behind the classification chamber 15 and separate breezes through rotor hole 16.The lingering remnants of past customs is got back to blower fan 1 by blower fan 1 import.Regulate fineness control valve adjusting knob 10, close following fineness and regulate valve block 4, open top fineness and regulate valve block 4, it is big that be drawn onto top ore powder granularity order number this moment, close top fineness and regulate valve block 4, open following fineness and regulate valve block 4, it is just little that be drawn onto top ore powder granularity order number this moment.Regulate the angle difference of fineness control valve adjusting knob 10, be drawn onto top ore powder granularity and also can change to some extent.Adjust the rotating speed of classification rotor 6 and can adjust the fineness height of producing breeze equally.Classification rotor 6 rotating speed height, the breeze order number that enters classification chamber 15 by rotor hole 16 is just big, and classification rotor 6 revolutions are low, and the breeze order number that enters classification chamber 15 by rotor hole 16 is just little.The effect of the aerofoil 7 in classification rotor 6 outsides is to seal by the discharge pipe of rotating air foil 7 blades to breeze hierarchy system 8.
