Abstract
An internal classification ball mill comprises a rotary ball mill cylinder driven by a driving device, wherein one side of the rotary ball mill cylinder is open, a stationary disk fixedly installed on a sliding seat is arranged at the opening position of the ball mill cylinder and forms a ball mill chamber together with the ball mill cylinder, and the sliding seat is installed on a track seat. A classifier, an adjustable air inlet pipe and a feeding screw conveyer are fixedly installed on the stationary disk, and a classifier impeller is arranged inside the ball mill chamber. The internal classification ball mill can realize classification of fine granules in the ball mill chamber, so as to reduce material pulverization, avoid the occurrence of superfine granules hindering coarse material pulverization, remarkably improve the pulverization efficiency, and reduce equipment energy consumption. The internal classification ball mill has the advantages of simple structure and small floor area; and can be used for pulverizing thermosensitive materials.
Description
Technical field
The utility model belongs to cylinder grater technical field, particularly a kind of ball mill with internal classification function.
Background technology
Ball mill is one of the most frequently used disintegrating apparatus of present powder production industry, and 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.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, makes that refacing appears in fine powder, overground phenomenon, thereby efficient is low, energy consumption is big, particularly in ultra-fine grinding, superfine powder can seriously hinder the continuation of coarse fodder to be pulverized, and reduces grinding efficiency greatly.In addition, also can gather a large amount of mechanical heat in the vexed mill,pot course of work temperature of charge is raise, heat sensitive material is caused adverse effect.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 that hinders that coarse fodder is pulverized and fine powder was refaced in the course of the work equally in this type, the particularly classified material of refacing that returns has had suitable fineness, have a strong impact on the pulverizing of coarse fodder after entering cylindrical shell, thereby exist production efficiency low equally, the defective that energy consumption is high.In addition, this type process route is longer, and floor space is big, and equipment investment is also bigger.
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, reduces the pulverizing of refacing of material, improves crush efficiency, reduces equipment energy consumption.
For achieving the above object, the technical scheme that the utility model internal grading ball mill adopts is, it comprises the ball grinding cylinder by the actuator drives rotation, one side of ball grinding cylinder is opened wide, be provided with the quiet dish that is fixedly mounted on the sliding seat at its aperture position, quiet dish and ball grinding cylinder constitute the ball milling chamber, and ball milling is equipped with abrading-ball in the chamber, and sliding seat is installed on the railroad shoe.Be installed with clasfficiator, adjustable blast pipe and charging screw feeder at Jing Panshang, the clasfficiator impeller of clasfficiator is arranged in the ball milling chamber.
Internal grading ball mill as mentioned above is provided with many directed blowers on its adjustable blast pipe stretches into part in the ball milling chamber.
Internal grading ball mill as mentioned above, its ball grinding cylinder that adopts is the short ball mill tube, its cylindrical shell length is 500-1500mm.
Internal grading ball mill is inlaid with the wear-resisting lining of being made by high-abrasive material at ball grinding cylinder inwall and quiet dish inwall as mentioned above.
The utility model is owing to be provided with clasfficiator on ball grinding cylinder, adjustable blast pipe and clasfficiator impeller cooperate and can in time qualified particle be discharged, promptly in the ball milling chamber, can realize the classification of fines, reduced refacing and pulverizing excessively of material, avoided superfine powder to hinder the situation that coarse fodder is pulverized, thereby improved crush efficiency greatly, reduced equipment energy consumption.Since will pulverize with grading design be one, the utility model is simple in structure, technological process is short, area occupied is little, equipment manufacturing cost is low, and is convenient to maintenance.In addition, because adjustable blast pipe is blown into air continuously in the ball milling chamber, played the thermolysis in the crushing process, thereby the utility model is applicable to the pulverizing of heat sensitive material.

Fig. 2 is the left view of Fig. 1;
Fig. 3 is the A-A cutaway view among Fig. 1.
The specific embodiment
The accompanying drawing illustrated embodiment, the utlity model has the ball grinding cylinder 18 that drives rotation by transmission device 23, transmission device 23 comprises the power transmission shaft 22 that is driven by speed changer 24 by motor and is fixed on boss 21 on the power transmission shaft 22, whole transmission device 23 is by being bolted on the basis, ground, and ball grinding cylinder 18 1 side central authorities are connected as one by bolt and boss 21.Said ball grinding cylinder 18 is the short ball mill tube, and its cylindrical shell length is 500-1500mm.The opposite side of ball grinding cylinder 18 opens wide, be provided with a fixing quiet dish 13 at this aperture position, quiet dish 13 constitutes the ball milling chamber with ball grinding cylinder 18, and abrading-ball 5 is housed in the ball milling chamber, is inlaid with the wear-resisting lining of being made by high-abrasive material 20,17 respectively at ball grinding cylinder 18 inwalls and quiet dish 13 inwalls.Quiet dish 13 is installed on the sliding seat 4 by bolting, and sliding seat 4 is installed in by attachment bolt 3 on the railroad shoe 2 that has slide rail 1, and railroad shoe 2 is by being bolted on the basis, ground.Be installed with clasfficiator 9 on quiet dish 13 tops by bolt 10, the clasfficiator impeller 12 of clasfficiator 9 is arranged in the ball milling chamber, and the air outlet 11 of clasfficiator 9 is connected with extractor fan.At clasfficiator 9 upsides the adjustable blast pipe 14 that is installed in by bolting on the quiet dish 13 is arranged, have volume damper 15 on the adjustable blast pipe 14, on adjustable blast pipe 14 stretches into part in the ball milling chamber, be provided with many directed blowers 16.The guard shield 19 that is fixedly mounted on quiet dish 13 inboards is arranged, in case abrading-ball 5 damages clasfficiator impeller 12 and adjustable blast pipe 14 when falling above clasfficiator impeller 12 and adjustable blast pipe 14.At clasfficiator 9 downsides the charging screw feeder 6 that is fixedly mounted on by bolt 8 on the quiet dish 13 is arranged, can be by feeding mouth 7 continuous charging in the ball milling chamber of charging screw feeder 6.
