Abstract
The utility model discloses a vertical funnel type magnetic levitation high-efficiency ball mill which comprises a rack, a tumbling box, a hollow shaft, a bearing seat and a transmission mechanism, wherein the tumbling box is in loading type rolling match with the rack; the hollow shaft is arranged at the bottom inside the tumbling box; the bearing seat is arranged at the lower end of the hollow shaft; the transmission mechanism is arranged at the lower part outside the tumbling box; the transmission mechanism is in working match with a driving mechanism; a hitting plate is arranged at the upper end of the hollow shaft; a scrapper is arranged at the upper part of the tumbling box; the outer sides of the middle part and the upper part of the tumbling box are respectively matched with the rack through a magnetic levitation mechanism. According to the ball mill, the rack is in the working match with the tumbling box through the magnetic levitation mechanism, the frictional resistance of working parts is eliminated, and the rotation speed is increased; due to the arrangement that the hitting plate falls down, materials and mediums are subjected to secondary grinding. The ball mill is of a vertical structure and is small in occupied space, the rotation speed of the ball mill is 3-5 times higher than that of a horizontal milling machine, and the secondary grinding is realized by falling down the hitting plate, so that the modicum crushing frequency is improved, and the grinding efficiency is improved.
Description
Technical field
The utility model belongs to the preparation equipment technical field, is specifically related to a kind of simple in structurely, and grinding efficiency is high, the vertical bucket type magnetic suspension efficient ball mill that floor space is little.
Background technology
The ball mill that uses both at home and abroad at present nearly all is horizontal, and floor space is large, production capacity is limited, need supporting classifying equipoment.The ball mill of prior art all is to rotarily drive medium and material by tumbling box to make the purpose that the waterfall stream mode falls to reaching ore grinding, therefore the rotary speed of tumbling box is subject to the restriction of critical speed, rotating speed is too high, medium is attached to rotate together in the tumbling box and loses grinding efficiency, and rotating speed is excessively low, and medium does not reach effective depth, can not form waterfall stream, grinding efficiency is also poor, and material often reaches granularity requirements and also can again be ground, and causes overground phenomenon.A kind of vertical ball mill of report is also arranged, and its grinding mill barrel maintains static, and form limited dynamic mill chamber by the driver chuck blade that is installed on the main shaft with annular mill road, but the disposal ability of the grinding machine of this structure is restricted.For this reason, develop a kind of simple in structurely, grinding efficiency is high, and the vertical bucket type magnetic suspension efficient ball mill that floor space is little is the key point that overcomes the above problems.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and grinding efficiency is high, the vertical bucket type magnetic suspension efficient ball mill that floor space is little.
The purpose of this utility model is to realize like this, comprise frame, tumbling box, quill shaft, bearing block, transmission mechanism, described tumbling box rolls with the frame bearing-type and cooperates, described tumbling box inner bottom part arranges quill shaft, the quill shaft lower end arranges bearing block, the outer bottom of described tumbling box arranges transmission mechanism, described transmission mechanism cooperates with driving mechanism work, described quill shaft upper end is provided with crash panel, described tumbling box top is provided with scraper plate, in the described tumbling box, upper outside respectively by magnetcisuspension mechanism and frame movingly.
The utility model frame and tumbling box cooperate by magnetic suspension mechanism work, eliminate the frictional resistance of workpiece, have improved rotating speed; Material and working media in the quill shaft upper end medium be set simultaneously and fall crash panel, so that can be realized up and down re-compounded grinding campaign.The combination of high rotating speed and multiple grinding motion has improved grinding efficiency greatly, and then improves the production capacity of grinding machine.The utility model adopts vertical structure, and floor space is little.Its rotating ratio is high 3～5 times with the horizontal grinding machine of diameter, and mutual roll extrusion was ground when medium and material were done the spiral rising, realizes regrind by falling crash panel, so that the frequency of medium muck also improves several times, has improved greatly grinding efficiency.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, but never in any form the utility model is limited, any conversion or replacement based on the utility model training centre is done all belong to protection domain of the present utility model.
As shown in Figure 1, the utility model comprises frame 16, tumbling box 1, quill shaft 2, bearing block 3, transmission mechanism 13, described tumbling box 1 rolls with frame 16 bearing-types and cooperates, described tumbling box 1 inner bottom part arranges quill shaft 2, quill shaft 2 lower ends arrange bearing block 3, described tumbling box 1 outer bottom arranges transmission mechanism 13, described transmission mechanism 13 cooperates with driving mechanism work, described quill shaft 2 upper ends are provided with crash panel 6, described tumbling box 1 top is provided with scraper plate 5, in the described tumbling box 1, upper outside is passed through magnetcisuspension mechanism and frame 16 movingly respectively.
Described magnetcisuspension mechanism is arranged at respectively the magnet ring group on the frame 16 and the ferromagnetic ring 9 of tumbling box 1 arranged outside that cooperates with it, and both cooperate in floated work.
The longitudinal section of described frame 16 is symmetrical " F " shape, and upper magnetic ring group 8 and lower magnet ring group 10 are set respectively on described frame 16 end faces and the lower floor's platform, respectively with 9 floated cooperations of upper and lower ferromagnetic ring of tumbling box 1 arranged outside.
Described magnet ring group comprises upper and lower magnet ring sheet, and the magnet ring sheet directly arranges isolating pad makes both be the U-shaped of horizontal, cooperates with the floated work of tumbling box 1 outside ferromagnetic ring, 9 mutually nested formulas.
Described magnet ring sheet is permanent magnet.
Described magnet ring group is permanent magnet.
