Description
Technical field
The utility model relates to the cylindrical shape grater of powder sector application, particularly relates to a kind of ball mill with internal classification function.
Background technology
Ball mill is one of the most frequently used pulverising apparatus of present powder production industry.Existing roller milling machine is generally vexed pot type and two kinds of versions of open type.Vexed mill,pot is to insert the material that need are pulverized in the machine and sealing, draws off in the lump until the fineness that is crushed to requirement, and be a kind of discontinuous running type ball mill.The shortcoming of this type is that the fine powder that constantly produces in the course of the work also will continue to participate in crushing process, make that refacing appears in fine powder, overground phenomenon, thereby it is low to grind efficient, energy consumption is big, and the heat of Chan Shenging is difficult to distribute in the course of the work, also can gather a large amount of mechanical heat temperature of charge is raise, make ball mill can not be used for the pulverizing of heat sensitive material.The open type ball mill is to adopt relatively long cylindrical shell, and material feeds continuously from an end, pulverizes the back and draws off continuously from the other end, and the coarse fodder after the classification returns feeding end again and participates in once more pulverizing.There is the fine powder crushing phenomenon of refacing in the course of the work equally in this type, and this type process route is longer, and floor space is big, the equipment manufacturing cost height.For addressing the above problem, the applicant has invented a kind of internal grading ball mill with classifying turbine, be adapted to the material material pulverizing that effectiveness of classification is had relatively high expectations, because its impeller internal classification apparatus structure is complicated, thereby manufacturing cost is higher, is not suitable for granularity requirements than hanging down and does not particularly require fine graded material grinding classification.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, and a kind of ball mill with internal classification function is provided, and can in time discharge qualified particle in the course of the work, improves crush efficiency, reduces equipment energy consumption, and simple and compact for structure.
For achieving the above object, the utility model adopts following technical scheme: it comprises the ball mill barrel that is driven rotation by drive unit, one side of ball mill barrel is uncovered, be provided with the stationary disk that is fixedly mounted on the sliding seat in this uncovered position, this stationary disk and ball mill barrel constitute the ball milling chamber, mill is housed in the ball milling chamber is situated between, sliding seat is movably arranged on the railroad shoe.Be installed with the air draught discharge nozzle that is connected with extractor fan in the stationary disk outside, on stationary disk, also be installed with pan feeding spiral and the anterior adjustable blast pipe that stretches in the ball milling chamber.
Air-flow back flushing type internal grading ball mill as mentioned above, two ball mill barrels can be installed symmetrically at the two ends of same drive unit, and promptly same drive unit drives two ball mill barrels simultaneously, realizes two-shipper work, with further raising production capacity, reduce floor space.
The utility model can be discharged qualified particle in the course of the work in time, in the ball milling chamber, can realize the classification of fines, reduce refacing and pulverizing excessively of material, avoid superfine powder to hinder the situation that coarse fodder is pulverized, thereby improved crush efficiency greatly, reduced equipment energy consumption.And technological process is short, and floor space is little, owing to be blown into air continuously in the ball milling chamber in the crushing process, heat can in time be distributed the pulverizing that is applicable to heat sensitive material.Owing to saved impeller internal classification device, further reduced manufacturing cost, improved crush efficiency.The utility model is particularly suitable for the relatively low material grinding classification of effectiveness of classification requirement.

The specific embodiment
Embodiment illustrated in fig. 1, the utlity model has the ball mill barrel 13 that drives rotation by drive unit, said drive unit comprises the power transmission shaft 16 that is driven by speed changer 18 by motor 19, be fixed with boss 15 in the end of power transmission shaft 16, the outside central authorities of ball mill barrel 13 are fixedly connected by bolt and boss 15, and drive unit fixes on the ground by base 17.This ball mill barrel 13 is a short cylinder, and promptly its cylindrical shell length is 500-1500mm.One side of ball mill barrel 13 is opened wide, and is provided with the stationary disk 8 that is fixedly mounted on the sliding seat 3 in this uncovered position, and stationary disk 8 constitutes the ball milling chamber with ball mill barrel 13, and abrading-ball 4 is housed in the ball milling chamber.Be inlaid with wear-resisting lining 14 respectively at ball mill barrel 13 inwalls and stationary disk 8 inwalls.The opening end of the outer rim of stationary disk 8 and ball mill barrel 13 leaves certain interval, and abrading-ball 4 can not be spilt, and is convenient to again relatively rotate.Stationary disk 8 is installed on the sliding seat 3 by bolting, and sliding seat 3 is installed in by attachment bolt on the railroad shoe 1 that has slide rail 2, and railroad shoe 1 is by being bolted on the basis, ground.Be installed with air draught discharge nozzle 7 in stationary disk 8 outsides, air draught discharge nozzle 7 is connected with extractor fan.At air draught discharge nozzle 7 downsides the pan feeding spiral 5 that is fixedly mounted on the quiet dish 8 is arranged, can be by material bin 6 continuous charging in the ball milling chamber of pan feeding spiral 5.At air draught discharge nozzle 7 upsides the adjustable blast pipe 10 that is fixedly mounted on the stationary disk 8 is arranged, have volume damper 9 on the adjustable blast pipe 10, on adjustable blast pipe 10 stretches into part in the ball milling chamber, be provided with many directed blowers 11.The guard shield 12 that is fixedly mounted on stationary disk 8 inboards is arranged, in case abrading-ball 4 damages adjustable blast pipe 10 when falling above adjustable blast pipe 10.
Embodiment illustrated in fig. 4, the utility model is at the two ends of same drive unit two ball mill barrels 13 to be installed symmetrically, promptly drives two ball mill barrels with same drive unit, and two-shipper is worked simultaneously.The ball mill structure of each side is described consistent with the foregoing description.
In the utility model course of work, because air draught discharge nozzle 7 is connected with extractor fan, make in the ball milling chamber and be in negative pressure state, adjustable blast pipe 10 can be dried to ball milling chamber interior orientation by a plurality of directed blowers 11, pulverized thin material is blown afloat, qualified particle is discharged by air draught discharge nozzle 7, has realized the effect of tube internal classification in the crushing process.Adjust the volume damper 9 on the adjustable blast pipe 10, can obtain the material product of different fineness.
During maintenance, unclamp the attachment bolt of sliding seat 3 and railroad shoe 1, sliding seat 3 can drive stationary disk 8 and outwards shift out along slide rail 2 together with air draught discharge nozzle 7, adjustable blast pipe 10 and pan feeding spiral 5, thereby keeps in repair very convenient.
