Abstract
The utility model relates to abrasion-resistant composite lining plates for a ball grinder. The lining plate is arc-shaped in appearance, and a group of the lining plates of the same specification are spliced end to end to form a cylinder which is matched with the inner diameter of the cylinder body of the ball grinder. The abrasion-resistant composite lining plates are characterized in that gaps are respectively formed in the inner sides and the outer sides of two ends of each arc-shaped lining plate; during end-to-end splicing of the lining plates, the gap in the inner side of one lining plate is matched with the gap in the outer side of the adjacent end of another lining plate. Compared with the prior art, the abrasion-resistant composite lining plates for the ball grinder have the advantages that the abrasion-resistant composite lining plates and the cylinder body can be tightly connected, and all the lining plates can be also tightly connected with one another without bolts; the mounting is convenient, and the labor intensity is reduced. The single lining plate can be independently dismounted and is convenient to replace, and the time and labor are saved. Each lining plate adopts a double-layer structure, so that valuable abrasion-resistant metal materials can be saved; meanwhile, a lining plate base body is made of a softer material, so that abrasion to the cylinder body is avoided.
Description
Technical field
The utility model relates to a kind of wear-resisting composite liner, is specifically related to a kind of wear-resisting composite liner for ball mill.
Background technology
Ball mill is lump material to be broken into the machine of granular material, ball mill barrel rotation when producing, and drive material and steel ball in cylinder to be rotated formation drop percussion movement.Lean on steel ball and material and barrel mutually to clash into, and the mutual shock rubbing action between material and steel ball is made powder by lump materials such as ores.
Grinding of ball grinder barrel is comprised of cylindrical shell and the liner plate that is arranged on cylindrical shell conventionally.Liner plate mode how with bolts or welding is fixed on cylindrical shell.With bolts, because bolt connection stress surface is little, under the impact of abrasive material, bolt is easily cut off comes off liner plate integral body.Adopt the mode of welding to connect, welding process can produce welding stress may make liner plate distortion, and liner plate dismounting difficulty, wastes time and energy.Current liner material quality used mainly contains potassium steel, Low Alloying Multicomponent Steels, Cr series white cast iron etc.Adopt single metal material to make liner plate, liner plate anti-wear performance is good, and hardness is high, but toughness is poor, is in use subject to impacting easy fracture failure, simultaneously due to the hardness of liner plate hardness higher than cylindrical shell, in use can cause cylindrical shell wearing and tearing even worn out.Therefore, use single metal material to prepare liner plate and can not meet actual needs owing to can not taking into account high tenacity, high rigidity, high-wearing feature.
The utility model patent of patent No. CN2292609Y " ball grinding machine lining board ", a kind of ball mill abrasion-proof backing block is disclosed, there is the kerve that can place securing member afterbody liner plate inside, and the vertical slot that can allow fastener head stretch out, in one end of vertical slot and kerve, there is the translot that can allow securing member afterbody put into kerve, the advantage of this patent is to adopt the mounting groove structure consisting of vertical slot and kerve, the problem of stress concentration having produced while having avoided screw that original use connects, but, what this patent liner plate still adopted with cylindrical shell is that bolt is connected, therefore can not effectively improve due to bolt strained excessive phenomenon of cutting off.The utility model patent of patent No. XN2757924Y " bimetal composite dovetail type self-fixing lining plate ", disclose a kind of dovetail type self-fixing lining plate, at the left and right side of liner plate, dovetail type inclined-plane has been set respectively, during installation, adjacent liner plate left and right face is mutually locked, without fixing with bolt.The weak point of this patent is: only considered interconnecting between liner plate, do not relate to being connected between liner plate and cylindrical shell, in use procedure, between liner plate and cylindrical shell, can relatively move, and all the other liner plates can all collapse owing to losing support after a certain liner plate breaks.The utility model patent of patent No. CN201912975U " a kind of high wear-resistant bi-metal composite lining board ", discloses a kind of high wear-resistant bi-metal composite lining board, and it comprises liner plate matrix and inserts, the position, protruding peak of inserting setting and liner plate.The weak point of this patent is: the wear-resisting property on liner plate surface is inconsistent, and in use procedure, abrasive material can wear and tear matrix and cause inserting and come off.Patent No. CN201807423U utility model patent " ball grinding machine lining board ", a kind of ball grinding machine lining board is disclosed, comprise: liner plate body, wearing layer, bolt hole, square head bolt, cylindrical shell, deposited one deck wearing layer above liner plate body, after wearing layer wear and tear overrun, need not change liner plate, directly deposited one deck wearing layer on liner plate body again.The weak point of this patent is: direct liner plate surface deposited metal one deck wearing layer again, local high temperature may cause liner plate distortion, produce gap and can cause the phenomenon of leaking powder, spillage to occur, and this technique is very high to operation requirements between liner plate.On liner plate, have bolt hole, screw can crack source in casting and heat treatment simultaneously, and in use, liner plate easily ruptures from screw.Patent No. CN2765769Y utility model patent " rich chromium cast iron thin-walled composite liner ", discloses a kind of good toughness, composite liner that intensity is high.Between two-layer high-chromium alloy cast-iron layer, the steel plate through pickling, polishing is set, on steel plate, offer some through holes, in through hole, fill rich chromium cast iron, prepare good toughness, composite liner that intensity is high, the weak point of this patent is: common carbon steel board is cast in rich chromium cast iron, on casting process light plate surface, contact and can be oxidized with the cast iron of molten state, in interface, produce a large amount of oxide inclusions and affect compound effect, and liner plate is two-sided is the rich chromium cast iron that hardness is high, in use procedure, the liner plate cylindrical shell that can wear and tear is even worn out.
