Abstract
The utility model relates to a novel lining plate for a ball mill, which comprises a basal body, a wear-resisting lining plate, composite magnetic pole groups and adhesive, wherein, the wear-resisting lining plate is arranged on the inner wall of the basal body; a cavity is formed in the wear-resisting lining plate; the composite magnetic pole groups are stuck to the cavity of the wear-resisting lining plate through the adhesive, and are arranged in the axial direction of a ball mill cylinder body in a homopolar manner and arranged in the circumferential direction of the ball mill in the N and S alternating manner; the wear-resisting lining plate is cast through adopting a special ZG80Mn 15Cr4; each composite magnetic pole group is formed by a high-performance ferrite material and a high-performance alloy magnetic steel; and the adhesive is made of a novel U.S. 1st line material. The utility model has the advantages of reasonable structural design, higher magnetic field strength and long service life, and can be widely applicable to ball mills.
Description
Technical field
The utility model relates to a kind of shoe, particularly relates to a kind of novel magnetic liner plate of ball mill.
Background technology
Ball mill is the key equipment of ore dressing engineering, and magnetic liner plate is the core component of ball mill simultaneously, and its consumption accounts for whole ore dressing processing totle drilling costs about 5%.By the operating position of present magnetic liner plate, it uses average unit cost only is 38% of high manganese steel lining plate.And grinding machine can be energy-conservation more than 30%.Because reasons such as equipment and materials, structure and magnetic field structures, ball mill is not widely used in ore dressing field at present, and especially ball radius is greater than the primary grinding of 100mm, and most of field of poor working environment.Use though magnetic liner plate is existing, the life-span, only about 1 year, economic effect was not obvious.
The utility model content
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, wear-resisting effective novel magnetic liner plate of ball mill.
In order to address the above problem, the utility model by the following technical solutions:
A kind of novel magnetic liner plate of ball mill comprises matrix, abrasion-proof backing block, composite pole group and bonding agent, on the matrix inwall abrasion-proof backing block is set, and is provided with cavity in the abrasion-proof backing block, and the composite pole group is bonded in the cavity of abrasion-proof backing block by bonding agent.
The composite pole group is that same polarity is arranged along the ball mill barrel axial direction, is that N, S alternately arrange along the ball mill barrel circumferencial direction.
Compared with prior art, the beneficial effects of the utility model are:
1, abrasion-proof backing block adopts special ZG80Mn15Cr4 casting, have not characteristics such as magnetic property is good, wear-resisting, intensity height, and shock resistance is good.
2; the composite pole group adopts special arrangement mode; on the cylindrical shell circumferencial direction, just can form the waveform protective layer; replaced the functional requirement of primary grinding to the waveform liner plate; the composite pole group is made up of high performance ferrite material and high performance alloys magnet steel simultaneously; formed higher magnetic field intensity on the liner plate surface; the thickness of waveform protective layer and the thickness of waveform increase along with the increase of the intensity in magnetic field; average magnetic field intensity can reach as high as 180mT according to the primary grinding operating mode; the protective layer thickness maximum can reach 60mm, and the impact to liner plate all plays a good protection thicker protective layer for the wearing and tearing of liner plate and milling medium.
3, bonding agent adopts the blue new material of U.S.'s good fortune generation; have characteristics such as corrosion-resistant, that damping performance is good, can successfully manage extreme industrial and mineral, protection magnetic pole group is not oxidized; the impact of primary grinding operation is simultaneously effectively slowed down under the protection of bonding agent, and the magnetic pole group life-span further strengthens.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
A kind of novel magnetic liner plate of ball mill as shown in Figure 1, comprises matrix 1, abrasion-proof backing block 3, composite pole group 2 and bonding agent 4.On matrix 1 inwall abrasion-proof backing block 3 is set; abrasion-proof backing block 3 is made by high-strength, high-anti-friction cast steel; play protection magnetic pole group; the percentage composition of each composition is in the abrasion-proof backing block 3: C:0.7%～0.9%, Mn:14%～16%, Cr:3.95%～4.05%; Si≤1.0%; S≤0.03%, P≤0.06%, all the other are Fe.Be provided with cavity in the abrasion-proof backing block 3; composite pole group 2 is bonded in the cavity of abrasion-proof backing block 3 by bonding agent 4; bonding agent 4 adopts the blue new material of U.S.'s good fortune generation to make; have characteristics such as corrosion-resistant, that damping performance is good; can successfully manage extreme industrial and mineral; protection magnetic pole group is not oxidized; the elastomeric property of bonding agent 4 has also alleviated the impact endurance test shock that material and milling medium produce the magnetic pole group; the impact of primary grinding operation is effectively slowed down under the protection of bonding agent 4, and the magnetic pole group life-span further strengthens.Composite pole group 2 is made up of high performance ferrite material and high performance alloys magnet steel, and the magnetic field intensity of its generation is several times of Ferrite Material, and the magnetic field intensity that forms on abrasion-proof backing block 3 surfaces reaches as high as 180mT.Composite pole group 2 is that same polarity is arranged along the ball mill barrel axial direction; along the ball mill barrel circumferencial direction is that N, S alternately arrange; thereby on the cylindrical shell circumferencial direction, just can form the waveform protective layer; replaced the functional requirement of primary grinding to the waveform liner plate; the thickness of protective layer thickens along with the increase of the magnetic field intensity and the degree of depth, and the wavelength of waveform protective layer can change by the adjustment of distance between the magnetic pole group.
