Abstract
The utility model relates to a ball mill with a magnetic filling layer, which comprises a feeder, a supporting shaft, a barrel body, a discharge port and a power transmission part. The utility model is characterized in that the surface of a barrel body without an inner lining plate is provided with the magnetic filling layer, the inner surface of the barrel body is provided with a metal projection, and the power part and a discharge nozzle are connected with a centre transmission device. The utility model with simple manufacture increases the handling capacity of the material, and reduces noise, power consumption and steel consumption.
Description
The utility model relates to a kind of ball mill that adds the magnetic lining, belongs to the lapping device technical field.
In metallurgical industry, chemical industry, building materials industry, often need pulverize solid materials such as ore and grind, milling apparatus commonly used is a ball mill; Existing ball mill grinding equipment adopts cylindrical tube more, also have and adopt conic tube, no matter the profile of cylindrical shell why not have with, but protection liner plate in tube, being equipped with, when rolling to reduce abradant Metal Ball medium to the grinding loss of cylindrical shell, but this measure but can't be avoided the wearing and tearing of ball medium and liner plate except that having increased cylindrical shell weight; In addition, it is by the gear wheel of the outer suit of cylindrical shell and the pinion transmission of running part that the power of existing ball mill transmits, so, the cylindrical shell that has gear wheel and interior lining panel becomes very heavy, it is big to rotate noise, the power consumption height, the minimizing of material treating capacity certainly will be caused in a part of space in the cylindrical shell because interior lining panel accounts for.
The purpose of this utility model is, overcomes the shortcoming of prior art, and a kind of novel permanent magnetic ball mill is provided, and reduces power consumption steel consumption and noise, increases the day output of material.
The purpose of this utility model realizes by following measure:
Keeping existing ball mill barrel profile; bolster; under the constant situation such as input and output material and actuating unit; cylindrical shell is further improved; under the condition that interior lining panel is not set; for making the interior medium ball of tube alleviate the mill that bumps to cylindrical shell; outer surface or inner surface at cylindrical shell add the magnetic lining; make and form a protective layer by suction between magnetosphere and the little metal medium ball; big medium ball falls from the top down on the protective layer that bead forms; thereby collision and wearing and tearing between medium ball and the cylindrical shell have been avoided; reduced noise; owing to removed interior lining panel; the also corresponding dischargeable capacity that increases cylindrical shell; the material treating capacity is increased, and the cylindrical shell gross weight alleviates simultaneously, and the power that its transmission consumed is also corresponding to be reduced.
It is outer best that above-mentioned magnetic lining is located at cylindrical shell, no matter from reforming technology still from enlarging on the cylindrical shell volume, the magnetic lining all is to select advisably at barrel outer surface.More simple and easy to do and can make cylindrical shell durable in use in order on prior art, to implement the utility model, the magnetic lining can be that the thin piece of many small magnets embeds in the metal fin that is located on the drum surface and forms, it adds a protective layer, and protective layer can be used elastomeric material; Referring to Fig. 2.
The above-mentioned cylindrical shell that adds the magnetic lining, its inner surface or outer surface comprise that also the flange form at cylinder two ends fastens lid, and the setting of magnet can design by mentioned above principle according to its concrete shape and area on the surface of lid.
In order further to reduce the gouging abrasion of ball medium and cylindrical shell, add the metal small lugs at cylinder inner surface, evenly distributing substantially gets final product, and projection density and concrete size are decided according to the actual requirements.
Above-mentioned improvement to cylindrical shell can reduce the power consumption and the steel consumption (attrition of metal materials such as medium ball and interior lining panel) of ball mill widely, and the material treating capacity is improved widely.If be further improved, remove a part of weight that gear wheel on the cylindrical shell certainly will can alleviate cylindrical shell again at its motivation transfer motion part.Based on this consideration, the utility model adds at cylindrical shell on the basis of magnetic lining, and the discharging nozzle directly is connected with power section by shaft coupling, opens some discharging openings on the face of cylinder of discharge barrel, is advisable with 3-5.Above-mentioned power section comprises motor and decelerator, and is identical with prior art.Motor rotates thereby drive whole cylindrical shell by the discharge barrel on the decelerator drive shaft coupling.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model overall structure schematic diagram.Wherein, 1. dispenser, 2. charging aperture, 3. cylindrical shell, 4. magnetic lining, 5. lid, 6. bolster, 7. discharge barrel, 8. discharging opening, 9. shaft coupling, 10. decelerator, 11. motors, 12. pedestals.
Fig. 2 is the utility model drum surface magnetic lining schematic diagram.Wherein, a. floor map, the b. generalized section, hachure part 4i is the iron fin, and square part 4j is a magnet piece, and 4k is an external protection, the 3i. drum surface.
Embodiment 1. adds the magnetic lining at the barrel outer surface of existing ball mill, and the setting of magnetic lining as shown in Figure 2; Magnet piece is of a size of the thick 80x120x20(mm of length and width), the fin spacing is the wide of a magnet piece; Cylinder inner surface is cast with little metal coupling.
Embodiment 2. is as the cylindrical shell of embodiment 1 described ball mill, and different is cylindrical shell is without gear drive, and opens three discharging openings on the discharge barrel face of cylinder, and the discharging nozzle directly is connected with power section by shaft coupling; Overall structure as shown in Figure 1; Ore materials is sent into the cylindrical shell from dispenser, in the tube medium ball is arranged, start motor, motor drives the discharge barrel rotating cylinder by decelerator, and ore together rotates grinding with medium ball in cylindrical shell, overflow from discharging opening.
The utility model is applicable to all dry types or wet ball mill, and to metal, non-metallic ore, the chemical building material material grinds, day material handling amount than prior art increases 10-15%, noise reduces the 10-20 decibel, and it is about 20% that power consumption reduces, and the steel consumption reduces about 40%.
Claims (4)
