Description
Technical field
The present invention relates to a kind of self-shifting material-returning apparatus of globe mill, belong to the auxiliary equipment of ball mill.
Background technology
At present, ball mill has been widely used in the industries such as domestic and international mine, power plant, metallurgy, chemical industry, cement, and the grinding system research to ball mill is more extensive both at home and abroad in recent years.By the closed-circuit grinding system of traditional spiral classifier, cyclone, powder concentrator, on cement ball mill, invented the open circuit mill of screening in having again.The ball mill grinding system is summed up following kind:
(1) material utilizes the spiral classifier classification of peripheral hardware, and coarse fodder utilizes difference in height to be returned in the ball mill by feed end and grinds.
(2) material utilizes the cyclone classification of peripheral hardware, and coarse fodder utilizes difference in height to be returned in the ball mill by feed end and grinds.
(3) ball mill utilizes the powder concentrator classification of peripheral hardware, and coarse fodder utilizes difference in height to be returned in the ball mill by feed end and grinds.
(4) open circuit of screening mill in the cement ball mill that has adopts, discharging is qualified product.
In the ball mill grinding system, grader, powder concentrator all are the ball mill corollary equipments, occupy bigger position in factory building, have increased the factory building investment; Buy auxiliary facility investments such as grader, cyclone or powder concentrator and exterior line and will account for 1/3 of ball mill body; Energy resource consumption besides, grader, powder concentrator all are furnished with drive motor, and consumed power is wanted in operation continuously; Process route is long besides, equipment is many, has increased the fault rate of grinding system.The ball mill that uses is provided with a drum sieve at discharge end now, just is used for screening out the foreign material of material, does not have the grading and the returning charge function of grinding material.In the screening cement ball mill be to utilize the eyelet size of partition panel and discharging end plate to realize the classification of material, flow out than the material of small grain size, still stay in the mill than the material of coarsegrain and grind, its sieve plate is changed difficulty, the production capacity ball mill of opening a way is low.
Summary of the invention
The object of the present invention is to provide a kind of self-shifting material-returning apparatus of globe mill, simple in structure, replaced independently classifying equipoment and revert system, reduced the floor space of ball mill grinding system, saved investment, reduced energy consumption, reduced system failure probability.
Self-shifting material-returning apparatus of globe mill of the present invention, the lining that connects the discharging quill shaft is arranged, the outer end of lining is connected with drum sieve, the lining inwall is provided with the guide spiral with the ball mill switched in opposite, the drum sieve inwall is provided with ball mill and turns to identical pushing spiral, the guide tube that coarse fodder returns is housed in lining and the drum sieve, and guide tube inwall is provided with the returning charge spiral with the ball mill switched in opposite, returning charge hole on the terminal perisporium of guide tube.
The discharge end that is connected ball mill uses, and side flange, carries out classification and coarse fodder is returned grinding once more in the ball mill material on the end face of quill shaft with bolted in the lining.Grinding material is in the lining spiral imports drum sieve, qualified material enters in the discharging cover after sieving, and coarse fodder is shifted the end of drum sieve onto under screw action, enters in the guide tube from the returning charge hole, under the promotion of spiral, turn back in the ball mill and grind again, go round and begin again and realize from the classification returning charge.The eyelet (being sieve aperture) that gathers is gone up in the screen cloth available metal sheet material processing of drum sieve, and the size of eyelet requires to determine according to raw meal particle size.
Among the present invention:
The guide tube can be the overall structure of isometrical one-part form, also can be two-stage structure, can be isometrical, can be not isometrical yet, and can it is corresponding with drum sieve one section be designed to taper shape, be beneficial to away material.
Returning charge hole one side is set up arc and is carried flitch on the guide drum outer wall, is beneficial to the thick material after the screening is promoted and detains to the returning charge hole, enters in the guide tube.When carrying flitch coarse fodder being mentioned eminence, enter in the guide tube under extruding, gravity effect, a tube inside spin imports in the ball mill rapidly.
Between the inner end of lining and guide tube, establish isolation supports, as isolating support column etc., the one, support the guide tube, two do not hinder the outflow of material again, also have and stop mill ball to flow out the function of ball mill, can be designed to interconnective whole shape, as the disk of many legs etc.
Self-shifting material-returning apparatus of globe mill of the present invention, simple in structure, independently classifying equipoment and revert system have been replaced, reduced the floor space of ball mill grinding system, floor space or space reduce 1/2, and it is about 2/5 to reduce investment outlay, and has reduced energy consumption, reduced system failure probability, system failure rate can reduce 2/5.
Description of drawings
Fig. 1, one embodiment of the invention structural representation.
The guide tube of Fig. 2, embodiment of the invention returning charge bore portion and drum sieve cross-sectional structure enlarged diagram.
Among the figure: 1, quill shaft connecting plate 2, isolate support column 3, lining 4, guide tube 5, drum sieve 6, taper guide tube 7, carry flitch 8, returning charge hole.
The specific embodiment
The invention will be further described in conjunction with the foregoing description accompanying drawing.
As shown in the figure, self-shifting material-returning apparatus of globe mill of the present invention, the lining 3 that connects discharging quill shaft connecting plate 1 is arranged, 4 in the inner end of lining 3 and guide tube are provided with isolates support column 2, the outer end of lining 3 is connected with drum sieve 5, lining 3 inwalls are provided with the guide spiral with the ball mill switched in opposite, drum sieve 5 inwalls are provided with ball mill and turn to identical pushing spiral, guide tube 4 and taper guide tube 6 that coarse fodder returns are housed in lining 3 and the drum sieve 5, guide tube 4 and taper guide tube 6 inwalls are provided with the returning charge spiral with the ball mill switched in opposite, returning charge hole 8 on the terminal perisporium of taper guide tube 6, what returning charge hole 8 one sides were provided with arc on taper guide tube 6 outer walls carries flitch 7.
Technical process: the grinding material in the ball mill imports in the drum sieve 4 through the spiral of lining 3, and then enter in the taper guide tube 6, after drum sieve 5 screenings, qualified material enters in the discharging cover, coarse fodder is shifted the end of drum sieve 5 onto under screw action, flow into when mentioning eminence by carrying flitch 7 in the taper guide tube 6, the guide tube 4 of flowing through under the promotion of spiral turns back in the ball mill and grinds, goes round and begins again and realizes from the classification returning charge.
