Abstract
The utility model discloses a novel lining plate of a ball mill. The novel lining plate of the ball mill comprises a rubber lining plate body and an abrasion-proof layer, wherein the rubber lining plate body is formed by pasting a natural rubber layer and a nitrile rubber layer; the abrasion-proof layer is pasted on one side of the natural rubber layer; a first reinforcing rib is arranged on the natural rubber layer; a second reinforcing rib is arranged in the nitrile rubber layer. According to the novel lining plate of the ball mill, the two rubber layers with difference performances are arranged and the reinforcing ribs are arranged in the two rubber layers, so that the elasticity and the buffer performance of the lining plate in use are increased, and the service life of the lining plate is prolonged. In addition, the abrasion-proof layer is arranged, so that the abrasion resistance of the lining plate is improved and the abrasion loss of the lining plate is reduced.
Description
Technical field
The utility model relates to a kind of liner plate, in particular, and particularly a kind of New type ball mill lining plate.
Background technology
Ball mill is widely used in the industries such as metallurgy, mine, building materials, electric power as a kind of milling apparatus, ball mill adopts machine driving to make mill tube make low speed rotation, abrading-ball in cylinder is worn into thing to be ground (ore deposit, stone, coal etc.) graininess needing under then throwing because the effect of centrifugal force promotes.In the process grinding, liner plate is owing to being subject to clashing of abrading-ball, and wear extent is larger, shortened its service life, operating efficiency has also reduced greatly, needs often to change liner plate in actual production, has so both increased the production cost of enterprise, also reduced output, meanwhile, existing liner plate volume is large, and uses for a long time ball mill mill tube to be easily out of shape, dismounting and inconvenience thereof, thus the economic benefit of enterprise affected.
The patent No. is that 201110368120.3 Chinese utility model patent discloses a kind of ball grinding machine lining board, and liner plate body is wherein upper arc projection and lower arc fluting composition, and upper arc is protruding and lower arc fluting is tangent, and first place joins; In installing hole, be provided with abnormity nut; Abnormity nut is locked on bolt.Through inventor experiment, the shortcoming that this scheme exists is: when upper arc projection pounded flat after, often there is blocking the problem of material, had a strong impact on production efficiency.Therefore, need to design a kind of novel ball grinding machine lining board.
Utility model content
The purpose of this utility model is to provide that a kind of wear extent is little, the New type ball mill lining plate of long service life.
In order to solve problem set forth above, the technical solution adopted in the utility model is: a kind of New type ball mill lining plate, it comprises by caoutchouc layer and acrylonitrile-butadiene rubber layer pastes the rubber lining body forming, and be pasted on the wearing layer of caoutchouc layer one side, and described caoutchouc layer is provided with the first reinforcement, in described acrylonitrile-butadiene rubber layer, be provided with the second reinforcement.
According to a preferred embodiment of the present utility model: described wearing layer is ceramic wearing coat, and the surface of this ceramic wearing coat arc that is indent.
According to a preferred embodiment of the present utility model: described the first reinforcement and the second reinforcement are curved plate, and the arc opening side of described the first reinforcement and the arc opening side of the second reinforcement are oppositely arranged.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by arranging the rubber layer of two different performances, and be equipped with reinforcement in two rubber layers, and increased liner plate elasticity and shock-absorbing capacity in use, extended its service life; Be provided with in addition wearing layer, increased the wearability of liner plate, reduced the wear extent of liner plate.
Accompanying drawing explanation
Fig. 1 is the structural representation of New type ball mill lining plate of the present utility model.
Description of reference numerals: 10, wearing layer, 20, caoutchouc layer, 30, the first reinforcement, 40, acrylonitrile-butadiene rubber layer, 50, the second reinforcement.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Consult shown in Fig. 1, the utility model provides a kind of New type ball mill lining plate, it comprises by caoutchouc layer 20 and acrylonitrile-butadiene rubber layer 40 pastes the rubber lining body forming, and be pasted on the wearing layer 10 of caoutchouc layer 20 1 sides, and caoutchouc layer 20 is provided with the first reinforcement 30, in acrylonitrile-butadiene rubber layer 40, be provided with the second reinforcement 50.
Wherein, caoutchouc layer 20 has higher elasticity and is slightly with plasticity, while extraordinary mechanical strength again, hysteresis loss is little, when being repeatedly out of shape, heat-dissipating is low, and therefore its flexible resistance is also fine, and owing to being non-polar rubber, so electrical insulation capability is good, can prevent that abrading-ball from adding the static conduction producing man-hour.And acrylonitrile-butadiene rubber layer 40 is made through emulsion polymerization by butadiene and acrylonitrile, its oil resistivity is fabulous, and wearability is higher, heat resistance is better, bonding force is strong, can prevent and the friction of ball mill inwall, has prevented from damaging because ball mill inner wall temperature is too high whole liner plate simultaneously.
Concrete, wearing layer 10 be ceramic wearing coat, and the surface of this ceramic wearing coat arc that is indent, and abrading-ball is adding man-hour like this, can not drop in the curved surfaces slip of ceramic wearing coat and smashes the phenomenon of liner plate.
Preferably, the first reinforcement 30 and the second reinforcement 50 are curved plate, and the arc opening side of the arc opening side of the first reinforcement 30 and the second reinforcement 50 is oppositely arranged, and arrange like this, can guarantee, in the flexible situation of liner plate, further to increase the intensity of whole liner plate.
Generally speaking, the utility model is by arranging caoutchouc layer 20 and the acrylonitrile-butadiene rubber layer 40 of two different performances, and at interior increase the first reinforcement 30 of caoutchouc layer 20, at interior increase the second reinforcement 50 of acrylonitrile-butadiene rubber layer 40, greatly increase whole liner plate elasticity and shock-absorbing capacity in use, improved its service life; On the surface of caoutchouc layer 20, be provided with wearing layer 10 in addition, increased the wearability of liner plate, reduced the wear extent of liner plate.
Above-described embodiment is preferably embodiment of the utility model; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
