The secondary milling is realized by the dropping impact plate, so that the ore crushing frequency of mediums is increased and the grinding efficiency is increased.
Description
Technical field
The invention belongs to preparation equipment technical field, be specifically related to a kind of structure simply, grinding efficiency is high, the vertical bucket type magnetic suspension efficient ball mill that floor space is little.
Background technology
The ball mill used both at home and abroad is at present nearly all horizontal, and floor space is large, production capacity is limited, need supporting classifying equipoment.The ball mill of prior art is all rotarily drive medium by tumbling box and the object that waterfall stream mode falls to reaching ore grinding made by material, therefore the rotary speed of tumbling box is subject to the restriction of critical speed, rotating speed is too high, medium is attached in tumbling box to rotate together and loses grinding efficiency, and rotating speed is too low, and medium does not reach effective depth, waterfall stream can not be formed, grinding efficiency is also poor, and material often reaches granularity requirements and also can again be ground, and causes overground phenomenon.Also have a kind of vertical ball mill of report, its grinding mill barrel maintains static, and grind road and form limited dynamic mill room, but the disposal ability of the grinding machine of this structure is restricted by the driver chuck blade be arranged on main shaft with annular.For this reason, develop a kind of structure simple, grinding efficiency is high, and the vertical bucket type magnetic suspension efficient ball mill that floor space is little is the key point overcome the above problems.
Summary of the invention
The object of the present invention is to provide a kind of structure simple, grinding efficiency is high, the vertical bucket type magnetic suspension efficient ball mill that floor space is little.
The object of the present invention is achieved like this, comprise frame, tumbling box, quill shaft, bearing block, transmission mechanism, described tumbling box rolls with frame bearing-type and coordinates, described tumbling box inner bottom part arranges quill shaft, quill shaft lower end arranges bearing block, the outer bottom of described tumbling box arranges transmission mechanism, described transmission mechanism coordinates with driving mechanism work, described quill shaft upper end is provided with crash panel, described tumbling box top is provided with scraper plate, and in described tumbling box, upper outside coordinates respectively by magnetcisuspension mechanism and frame are dynamic.
Frame of the present invention and tumbling box are coordinated by magnetic suspension mechanism work, eliminate the frictional resistance of workpiece, improve rotating speed; Arranging medium in quill shaft upper end falls crash panel simultaneously, makes material and working media can realize upper and lower re-compounded grinding and moves.The combination that high rotating speed and multiple grinding move substantially increases grinding efficiency, and then improves the production capacity of grinding machine.The present invention adopts vertical structure, and floor space is little.Its rotating ratio is high 3 ~ 5 times with diameter horizontal mill, and when spiral made by medium and material, mutual roll extrusion is ground, and realizing regrind, making the frequency of medium muck also improve several times, greatly improving grinding efficiency by falling crash panel.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated, but limited the present invention never in any form, and any conversion done based on training centre of the present invention or replacement, all belong to protection scope of the present invention.
As shown in Figure 1, the present invention includes frame 16, tumbling box 1, quill shaft 2, bearing block 3, transmission mechanism 13, described tumbling box 1 rolls with frame 16 bearing-type and coordinates, described tumbling box 1 inner bottom part arranges quill shaft 2, quill shaft 2 lower end arranges bearing block 3, the described outer bottom of tumbling box 1 arranges transmission mechanism 13, described transmission mechanism 13 coordinates with driving mechanism work, described quill shaft 2 upper end is provided with crash panel 6, described tumbling box 1 top is provided with scraper plate 5, and in described tumbling box 1, upper outside coordinates respectively by magnetcisuspension mechanism and frame 16 is dynamic.
The ferromagnetic ring 9 of tumbling box 1 arranged outside that described magnetcisuspension mechanism is arranged at the magnet ring group in frame 16 respectively and coordinates with it, both coordinate in floated work.
Longitudinal section " F " shape symmetrically of described frame 16, described frame 16 end face and lower floor's platform arranges upper magnetic ring group 8 and lower magnet ring group 10 respectively, coordinates respectively with the upper and lower ferromagnetic ring 9 of tumbling box 1 arranged outside is floated.
Described magnet ring group comprises upper and lower magnet ring sheet, and magnet ring sheet directly arranges the U-shaped that isolating pad makes both in horizontal, coordinates with the floated work of the mutually nested formula of ferromagnetic ring 9 outside tumbling box 1.
Described magnet ring sheet is permanent magnet.
Described magnet ring group is permanent magnet.
Described tumbling box 1 is in infundibulate.
Described scraper plate 5 is arranged by scraper shaft 4, and described scraper plate 5 is at least two groups.
Arrange into ore deposit chute 7 above described tumbling box 1.
Described tumbling box 1 top is provided with weight bearing roller wheels 12, and described weight bearing roller wheels 12 rolls with circular orbit 11 bearing-type and coordinates.
Described driving mechanism comprises motor 15 and reductor 14, to be driven coordinate by drive with the transmission mechanism 13 that tumbling box 1 is arranged.

operation principle of the present invention and the course of work:
Frame of the present invention and tumbling box are coordinated by magnetic suspension mechanism work, eliminate the frictional resistance of workpiece, improve rotating speed; Arranging medium in quill shaft upper end falls crash panel simultaneously, makes material and working media can realize upper and lower re-compounded grinding and moves.The combination that high rotating speed and multiple grinding move substantially increases grinding efficiency, and then improves the production capacity of grinding machine.
During work, described working media and material feed from entering ore deposit chute, and motor drives tumbling box to run up, and scraper shaft maintains static.Be deposited in medium bottom tumbling box and material bores wall spiral along tumbling box, now medium forms abrasive action, when spiral scrapes to being forced shock during scraper plate place, this is first time muck operation, then down hit at a high speed to drop on crash panel and cause second time muck, drop into bottom tumbling box, the speed of pounding under it is greater than free-fall velocity, so circulates again.When tumbling box runs up, the ore pulp in mill can form whirlpool, and granularity is little compared with thin material centrifugal force, concentrates on whirlpool center and top and is discharged by the top of quill shaft and tumbling box perforate, reach the object of ore grinding.Larger than the hoisting depth of the horizontal mill medium of same diameter, therefore unit volume production capacity is large.
