Abstract
The utility model provides a slow-down lining plate through a horizontal roller abrasive layer edge effect, which comprises a lining plate abrasion resistant area and flanges. Length of a compression roller abrasion resistant area is a certain size slightly shorter than length of the lining plate abrasion resistant area, and two flanges are arranged on two sides of the lining plate abrasion resistant area. When a compression roller grinds a material layer, due to the effect of force, the middle of the material layer is compacted, materials on two sides are spilled out two sides of a grinding area formed by the compression roller abrasion resistant area and the lining plate abrasion resistant area, and the flanges on two sides of the abrasion resistant lining plate can block the material layer so as to enable the material layer to be spilled out from two sides of the grinding area difficultly. A stable material bed can be formed between the compression roller and the lining plate, simultaneously the slow-down lining plate can guarantee that the material layer on the whole grinding area is compacted, improves grinding efficiency, and simultaneously avoids the problem of uneven abrasion of the compression roller and the lining plate caused by material spilling.
Description
Technical field
The utility model relates to the roller mill that crouches, and the edge effect of particularly a kind of roller abrasive material for sleeping in slows down liner plate.
Background technology
The roller mill that crouches is the milling equipment of materials such as a kind of flyash, slag.During operate as normal; Grinding mill barrel rotates with supercritical speed, after the material in the entering grinding machine falls into feeding zone, under cylindrical shell interior lining panel skin-friction force and self action of centrifugal force; Being attached at cylinder inboard wall rapidly rotates with cylindrical shell; Form the material bed in the grinding district, receive the co-extruded of shell liner and pressure roller and mill, thereby make material be able to grinding, attenuate.The length of shell liner and pressure roller equates (as shown in Figure 1) basically in the market.But since flyash go into mill before particle just thinner, moisture is very low, and is mobile fairly good; This just is difficult to form the stable bed of material, and in the process of extruding, the material that is positioned at material bed both sides is under the effect of extruding force; Can be excessive to the pressure roller edge the non-zone of rolling, cause the material of pressure roller centre to be compacted, the material of both sides can't be compacted; Thereby reduced the efficient of grinding, also made the wearing piece of the roller mill that crouches produce the uneven wear phenomenon, increased rate of breakdown; Shorten the service life of parts, strengthened the later maintenance workload.
Summary of the invention
The utility model technical problem to be solved is; Overcome the deficiency of prior art, provide a kind of simple and reasonable roller abrasive material for sleeping in edge effect to slow down liner plate, easy to install; The roller abrasive dust that is suitable for crouching grinds good fluidity, is difficult to form the material of expecting bed, the edge effect that slows down the bed of material.
The utility model is that the technical scheme that its technical problem of solution is adopted is: the length in the wear-resisting district of pressure roller is added with the twice flange than the short a little certain size of the length in the wear-resisting district of liner plate respectively in the both sides in the wear-resisting district of liner plate.In the process of rolling, the flange through both sides blocks to excessive material, material can be maintained roll intra-zone.
The beneficial effect of the utility model is: can slow down the edge effect of material bed effectively, improve mill efficiency, reduce equipment failure rate.
Description of drawings
Fig. 1 rolls district's work sketch map for tradition;
Fig. 2 rolls district's work sketch map for the utility model;
Fig. 3 is the structural representation of the utility model;
Fig. 4 is the left view of Fig. 3.
Among the figure: 1 is pressure roller, and 2 is the bed of material, and 3 is liner plate, and 3-1 is the wear-resisting district of liner plate, and 3-2 is a flange.
The specific embodiment
The utility model provides the edge effect of a kind of roller abrasive material for sleeping in to slow down liner plate, comprises liner plate wear-resisting district 3-1 and flange 3-2.The length in pressure roller 1 wear-resisting district is than the short a little certain size of the length of the wear-resisting district of liner plate 3-1, and the both sides of 3-1 are added with twice flange 3-2 respectively in the wear-resisting district of liner plate.
When 1 pair of bed of material 2 of pressure roller rolled, the bed of material 2 can be because the effect of power, being compacted of mid portion; The material of both sides then can overflow to the both sides of rolling the district that the wear-resisting district of pressure roller 1 and liner plate 3-1 forms; At this moment, the flange 3-2 of liner plate 3 both sides will play the effect that stops to the bed of material 2, makes the bed of material 2 be difficult to overflow from rolling the both sides, district; Can between pressure roller 1 and abrasion-proof backing block 3, form more stable material bed like this; Can guarantee that simultaneously the bed of material 2 all is compacted on the whole length that rolls the district, improve the efficient of grinding, avoid again simultaneously because the uneven wear problem of the excessive pressure roller that causes of material 1, liner plate 3.
Claims (2)
1. a roller abrasive material for sleeping in edge effect slows down liner plate, comprises the wear-resisting district of liner plate, it is characterized in that: the both sides in the wear-resisting district of liner plate are added with the twice flange respectively.
2. edge effect slows down liner plate according to the said a kind of roller abrasive material for sleeping in of claim 1, and it is characterized in that: the length in the wear-resisting district of liner plate is longer than the length in the wear-resisting district of pressure roller.
