Abstract
The utility model discloses a crushing device of a single roll crusher. The crushing device comprises roll teeth, a grate plate holder and a grate plate, wherein the grate plate is arranged on the grate plate holder, and symmetrically arranged up and down; a concave arc scrapping table is arranged at the middle part of the grate plate; a lug boss is arranged at one end of the grate plate, and adopts an up-and-down symmetrical design. The scrapping table disclosed by the utility model can timely clean ores accumulated between the roll teeth, so that the operation resistance of the single roller crusher is reduced, the service life of the grate plate is prolonged, the utilization rate of the material is improved, the cost of spare parts is reduced, the cleaning strength is reduced, and the crushing effect is improved. By adopting the grate plate which is symmetrically arranged up and down, wear-resistant materials are surfaced on the upper and lower surfaces as work surfaces. The grate plate is extracted from the grate plate holder, and can be installed in an interchange manner up and down after one surface is abraded.
Description
Technical field
The utility model relates to technical field of smelting, is specifically related to a kind of breaker of single roll crusher.
Background technology
In smelting industry, because of the requirement of technique, roast need to be become the material (as agglomerate) of bulk to carry out fragmentation, for next process provides the material that granularity is qualified.Single roll crusher is mainly responsible for the primary breakup task to large stretch of agglomerate that on last process sintering pallet, monoblock unloads, and is about to agglomerate and is crushed to below 200～300mm.Its crusher members is comprised of roller tooth and grate plate, when single roll crusher is in rotary course, rotating roller tooth is incorporated into agglomerate on grate plate, a tooth of its roller tooth is when being fixedly mounted on the grate plate gap on base, tooth both sides and fixedly relative motion generation shearing force between grate plate, agglomerate completes fragmentation under the pressure acting in conjunction of this shearing force and tooth.In use, this single roll crusher grid plate has the following disadvantages:
1,, in material roast process, because raw material mix changes or sintering process control variation can cause agglomerate burning, the molten mass of now forming scoriform enters adjacent two roller between cog, and gathers in a large number, bonds, forms long-pending ore deposit sometimes.On the one hand, this not only affects crushing effect, is unfavorable for that sintering process index controls, but also can causes the inordinate wear of grate plate middle, shortens grate plate service life; On the other hand, increase single roll crusher running resistance, made motor coupler pin wearing and tearing aggravation; Must regularly stop the long-pending ore deposit of single roll crusher roller between cog is cleared up, not only clear up difficulty large, and disposal costs be higher;
2, the design of position limiting structure is along its length heavy, also causes waste of material;
3, former grate plate structure is asymmetric up and down, is working face above, is non-working surface below; The shared volume of non-working surface is large, and material therefor is many, after the excessive wearing and tearing of grate plate working face, must change, and the grate plate changing is scrapped substantially, causes waste, and stock utilization is not high.
4, former roller tooth has only carried out local hardfacing processing at three tooth plate places, and remainder is not done any processing, causes like this tooth plate and fluted disc junction that inordinate wear occurs in During Process of Long-term Operation, thereby tooth plate fracture accident occurs.
Utility model content
The utility model, for problems of the prior art, provides a kind of breaker of single roll crusher.
The breaker of single roll crusher of the present utility model, comprises roller tooth, grate plate seat and grate plate disposed thereon, and described grate plate middle part is provided with material-scraping table.
In order to play position-limiting action, one end of described grate plate is provided with boss.
In order to improve stock utilization, extend grate plate service life, described grate plate is symmetrical arranged up and down, and upper and lower surface all can be used as working face, after a surface wear, grate plate is extracted out from grate plate seat, exchanges and installs up and down.
In order in time molten mass to be wiped off, described material-scraping table is concaved circular cambered surface.
The relative prior art of the utility model has the following advantages:
1, the material-scraping table of the present utility model long-pending ore deposit of cleaning roller between cog in time, has reduced single roll crusher running resistance, has extended grate plate service life, has improved stock utilization, has reduced spare part expense, has reduced clean-up intensity, has improved crushing effect.
2, positive stop lug boss simplicity of design of the present utility model, has avoided waste of material.
3, upper and lower symmetrically arranged grate plate of the present utility model, upper and lower surface is build-up wear-resistant material all, all can be used as working face, after a surface wear, grate plate is extracted out from grate plate seat, spins upside down installation.
4, roller tooth of the present utility model has carried out whole hardfacing processing, has not only extended its service life, has reduced spare part expense, and has stopped the generation of tooth plate fracture accident, has improved this operation rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of the utility model roller tooth, grate plate.
The specific embodiment
Below in conjunction with accompanying drawing, the breaker of a kind of single roll crusher of the present utility model is described in further detail.
As the breaker of Fig. 1, a kind of single roll crusher as shown in 2, comprise roller tooth 2, grate plate seat 3 and grate plate 1 disposed thereon, the grate plate 1 of processing through hardfacing is for being symmetrical arranged up and down, grate plate 1 middle part is provided with concaved circular cambered surface material-scraping table 5, and be arranged symmetrically with up and down, also carry out hardfacing processing, one end of grate plate 1 is provided with boss 6, and is arranged symmetrically with up and down; The all surface that pair roller tooth 2 contacts with material has carried out whole hardfacing to be processed.
During work, once there be molten mass to enter adjacent two roller between cog, before the uncolled bonding of molten mass, just by this concaved circular cambered surface material-scraping table 5, scraped, thereby stopped long-pending ore deposit, effectively reduce equipment running resistance, avoid grate plate inordinate wear; Because single roll crusher is rotated counterclockwise, and direction is constant, so castor bar is only subject to component to the right in the longitudinal direction, so only need set up a boss 6 at grate plate 1 right-hand member can play position-limiting action, and this positive stop lug boss is arranged symmetrically with up and down; Grate plate is upper and lower symmetrical structure, and upper and lower surface build-up wear-resistant material all, all can be used as working face, after a surface wear, grate plate is extracted out from grate plate seat, exchanges and installs up and down, reuses like this, has avoided waste of material; Pair roller tooth has carried out whole hardfacing to be processed, and has not only extended its service life, has reduced spare part expense, and has improved this operation rate.
