Abstract
The present invention relates to ball mill field, particularly a kind of ball mill magnetization abrasion-proof backing block, the metal level with grid pore structure is sequentially provided with ball mill body, one section of liner plate of the permanent magnet being bonded in this metal shell square hole and elastic glue-line composition, the side of every section of liner plate is provided with the radial direction keyway being coupled to each other, multistage liner plate is connected into whole lining by radial direction keyway, and wear-resistant alloy layer is provided with the inner surface of whole lining.When liner plate is installed, each section of liner plate is linked up using radial direction keyway and is expressed on ball mill barrel inwall and end cap, form ball mill whole lining.In operation process, one layer of protective layer being made up of Magnetic Materials and small ball fragment is formed on wear-resistant alloy layer inner surface.This ball mill magnetization abrasion-proof backing block service life is 56 times of high manganese steel lining plate, and weight is only the 45 60% of manganese, saves steel ball.
Description
Technical field
The present invention relates to ball mill field, particularly a kind of ball mill magnetization abrasion-proof backing block.
Background technology
Requirement to ball grinding machine lining board is wear-resistant, corrosion-resistant.The ball grinding machine lining board high-abrasive material master being commonly used
If using potassium steel as the various alloy steel liner plates of representative, as potassium steel system, chromium manganese molybdenum-iron boron system, high alloy chromium manganese vanadium system, in
The steel liner plates such as carbon silico-manganese steel system, another kind of is the nonmetallic materials liner plate using rubber as representative, as rubber lining, cast stone lining and cast stone,
Polyurethane liner plate etc., the common drawback of these liner plates are to denude quickly, and consumption is very big, it is necessary to regularly replace, and influences ball mill
Operating rate.Last century Mo, once developed metallic magnetic lining, metal-rubber magnetic liner plate, suitable for milling medium diameter
Two sections of≤60mm steel balls and ball mill is regrinded, but due to there are problems that in structure, so not being widely applied.
The content of the invention
It is an object of the invention to provide a kind of reasonable in design, simple and reliable for structure, anti-wear performance is good, the ball of service life length
Grinding machine magnetizes abrasion-proof backing block.
The purpose of the present invention is achieved through the following technical solutions.
Magnetize abrasion-proof backing block according to a kind of ball mill of the present invention, it is characterised in that be sequentially provided with band in ball mill body
There is the metal level of grid pore structure, one section of lining of the permanent magnet being bonded in this metal shell square hole and elastic glue-line composition
Plate, the side of every section of liner plate are provided with the radial direction keyway being coupled to each other, and multistage liner plate is connected into whole lining by radial direction keyway,
Wear-resistant alloy layer is provided with the inner surface of whole lining.
Further, described permanent magnet be the interlaced arrangement of a pair of magnetic poles magnetic patch, i.e., the lastblock magnetic of a pair of magnetic patch
Body polarity is S-N, and next piece of magnet polarity is N-S, and it is N-S and S-N that adjacent pair magnetic polarity, which is then interlocked,.
Further, described elastic glue-line is rubber layer or polyamine lipid layer.
When liner plate is installed, each section of liner plate is linked up using radial direction keyway and is expressed to ball mill barrel inwall and end cap
On, form ball mill whole lining.In use, due to the effect of permanent magnet, formed on wear-resistant alloy layer inner surface one layer by
The protective layer of Magnetic Materials and small ball fragment composition.
It is an advantage of the invention that：
1st, wear-resistant, corrosion resistance and good, service life are 5-6 times of manganese；
2nd, in light weight, liner plate weight of the invention is only the 45-60% of manganese；
3rd, thickness of thin, liner plate thickness of the invention is the 70-80% of manganese thickness, so that the dischargeable capacity of ball mill increases
It is big by more than 5%；
4th, power consumption is saved.Due to reduce weight and constantly adsorbed in operation process irregular broken ball block as oneself
Protective layer, it is small when making the rotary inertia of ball mill more than with manganese, therefore can ball mill operation power consumption reduction 6-10%；
5th, steel ball is saved, due to having adsorbed largely broken steel ball block on magnetic liner plate, adds the contact surface of steel ball and liner plate
Product, effectively probability is ground between pulverized material and steel ball so as to increase；
6th, easy for installation, this liner plate is in light weight, is not connected with, by magnetic force and mutual extruding force be close to cylinder and
On end cap.This just without the auger shell keyhole on cylinder and end cap, was both easily installed, and alleviated the labor intensity of worker, avoided again
Because drilling and caused by leak ore deposit hidden danger.
Brief description of the drawings
Fig. 1 is the structure sectional view of the present invention.
Embodiment
Illustrate the embodiment of the present invention below in conjunction with the accompanying drawings.
As shown in figure 1, the present invention is a kind of ball mill magnetization abrasion-proof backing block, it is characterised in that in ball mill body 1 according to
It is secondary to be provided with 7 groups of the metal level 3 with grid pore structure, the permanent magnet 2 being bonded in the square hole of this metal shell 3 and elastic glue-line
Into one section of liner plate, the side of every section of liner plate is provided with the radial direction keyway 6 being coupled to each other, and multistage liner plate passes through radial direction keyway 6
Whole lining is connected into, wear-resistant alloy layer 4 is provided with the inner surface of whole lining.5 be the bed of material in figure.
Described permanent magnet 2 is the magnetic patch of the interlaced arrangement of magnetic pole, i.e., the lastblock magnet polarity of a pair of magnetic patch is S-
N, next piece of magnet polarity are N-S, and it is N-S and S-N that adjacent pair magnetic polarity, which is then interlocked,.
Described elastic glue-line 7 is rubber layer or polyamine lipid layer.
The magnetization abrasion-proof backing block of the present invention is also designed to other structures form, and these belong to present invention protection model
Enclose.
