Description
Technical field
The present invention relates to a kind of ball mill magnetic protection plate, particularly a kind of strong absorption affinity non-uniform magnetic-field permanent magnetism magnetic liner plate that can be used for one section ball mill.
Background technology
At present, ball mill is widely used in metal and the nonmetal operation of milling of selecting industries such as factory, cement plant and refractory material, pottery, electric power, and is the key equipment in the grinding process of mine.The most principal work parts are liner plate and milling medium in the grinding machine, milling medium and ore are to the impact and the wearing and tearing of ball mill liner, make lining board of grinder become one of main consumable material in the mill running, therefore, the quality of liner plate quality and performance directly has influence on the service life of ore grinding quality and grinding machine.
Ball mill adopt usually the manganese steel material by casting as liner, and because manganese must be connected on the grinding mill barrel through bolt, cause bolt hole to leak material easily general service life about 5 months after the wearing and tearing, pollute operation field.
Summary of the invention
Be to solve the technical problem that prior art exists, the utility model provides a kind of use high performance permanent magnetic materials, can surpass the metallic magnetic lining of the high field intensity depth of interaction that large-sized grinder more than the 90mm and primary grinding use with ball mill at the ore deposit medium.
For solving the problem in the prior art; the technical solution adopted in the utility model is: non-homogeneous permanent magnetic field metallic magnetic lining comprises: the not smart powder protective layer of magnetic conduction casing, main pole, lateral pole group, damping bar, protruding crossbeam, hold-down screw, magnetic conduction steel plate, non-magnetic conductive steel plate, iron, ball mill barrel.It does not have protruding crossbeam in the magnetic conduction casing outside; This liner plate has the opposite main pole group of two row magnetic poles, between the reverse main pole group of two row one group of lateral pole group is arranged, and pole orientation is opposite with the pole orientation of two row magnetic pole groups; Stud with the damping bar in two row main pole groups and horizontal secondary magnetic pole group and metal shell contact site; Damping bar, magnetic pole group, magnetic conduction steel plate are fixed on not on the magnetic conduction casing by screw.There is the smart powder protective layer of iron described liner plate upper end.Described metal shell is a non-magnesium hard alloy.The main pole group that is embedded in metal shell inside is a permanent-magnet material.
The beneficial effects of the utility model are: permanent-magnet material is embedded in the metal shell as ball grinding machine lining board; in use; because the adsorbable one deck Iron Ore Powder of effect of magnetic field force or the medium ball that grinds; thereby reduce the direct impact of medium and ore, have advantages such as wear-resisting, energy-conservation, protection grinding machine site work environment liner plate.
Below in conjunction with drawings and Examples the utility model is described further.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the combination schematic diagram of liner plate of the present utility model;
Fig. 3 is a perspective view of the present utility model.
Shown in the figure: the not smart powder protective layer 10 of magnetic conduction casing 1, main pole 2, main pole 3, lateral pole group 4, damping bar 5, protruding crossbeam 6, screw 7, magnetic conduction steel plate 8, non-magnetic conductive steel plate 9, iron, ball mill barrel 11.
The specific embodiment
Non-homogeneous permanent magnetic field metallic magnetic lining of the present invention mainly comprises shell and permanent-magnet material two large divisions, and wherein magnetic conduction casing 1 is not a non-magnesium hard alloy, and magnetic conduction casing top is not provided with the crossbeam 6 of projection.The crossbeam of projection can play the effect that promotes abrading-ball when ball mill turns round, improve the grinding efficiency of grinding machine, the energy consumption of reduction ball mill.The main pole group main pole 2 and the main pole 3 of two row magnetic pole reversed arrangement do not inlayed in the inside of magnetic conduction casing, centre in the reverse main pole of two row, increase by one group of horizontal secondary magnetic pole group 4, pole orientation is opposite with the pole orientation of two row main pole groups, can change the Distribution of Magnetic Field on liner plate surface, strengthen the depth of interaction in magnetic field.Main pole 2 and 3 and laterally secondary magnetic pole group 4 make by permanent-magnet material, can strengthen the liner plate magnetic field intensity in upper to greatest extent.Two row main poles 2 with 3 and laterally the position that contacts with magnetic conduction casing 1 not of secondary magnetic pole group 4 stud with damping bar 5, the damping bar mainly is the impact that magnetic material is subjected to when reducing mill running, the service life of prolongation magnetic liner plate.Be screwed magnetic conduction steel plate 8, non-magnetic conductive steel plate 9, play enhancing magnetic liner plate and the suction-operated of ball mill barrel magnetic force corrosion-resisting function.Shown in Figure 2ly can find out obviously that liner plate projection crossbeam 6 is protected.
Embodiment
According to ball mill size preparation proper angle and size ball mill housing.Design suitable height ball mill projection crossbeam (20-50mm) according to the effect field intensity
The installation of main pole 2: damping bar 5 is installed earlier, be not bonded at and on the magnetic conduction casing 1 main pole 2 be installed then, according to the field intensity magnetic circuit, select suitable magnet and magnetic patch, put into housing, install magnetic conduction steel plate 8, the effect of magnetic conduction steel plate be for enhancing magnet to the ball mill barrel absorption affinity, at last with screw 7 fixedly damping bar 5, magnetic pole group 2, magnetic conduction steel plate 8 on magnetic conduction casing 1 not.
The laterally installation of secondary magnetic pole: damping bar 5 is installed earlier, be not bonded at and on the magnetic conduction casing 1 horizontal secondary magnetic pole 4 be installed then, according to the field intensity magnetic circuit, select suitable magnet and magnetic patch, put into housing, install not magnetic conduction steel plate 9, with screw 7 fixedly damping bar 5, horizontal secondary magnetic pole 4, not magnetic conduction steel plate 9 on magnetic conduction casing 1 not.
The installation of main pole 3: damping bar 5 is installed earlier, be not bonded at and on the magnetic conduction casing 1 main pole 3 be installed then, according to the field intensity magnetic circuit, select suitable magnet and magnetic patch, put into housing, install magnetic conduction steel plate 8, the effect of magnetic conduction steel plate be for enhancing magnet to the ball mill barrel absorption affinity, with screw 7 fixedly damping bar 5, main pole 3, magnetic conduction steel plate 8 on magnetic conduction casing 1 not.
Magnetic liner plate is installed in cylindrical shell: directly liner plate is put into ball mill barrel 11, because magneticaction, liner plate will be adsorbed in ball mill barrel, but horizontal force magnetic force is not strong, therefore liner plate can translation in ball mill barrel, increases magnetic liner plate simultaneously and is distributed in the whole ball mill barrel 11.
Distribution of Magnetic Field is put into the smart powder of iron, broken steel ball as shown in Figure 2 in ball mill, is subjected to the magnetic field active force, and magnetisable material is adsorbed in and forms the smart powder protective layer 10 of iron on the liner plate.
