Abstract
The invention discloses a wear-resisting millstone and grinding roller of a vertical mill for slags, and comprises a grinding roller and a millstone. Opposite surfaces of the grinding roller and the millstone are both double-layer structures, outer layers are overlaying welding layers, and inner layers are cast steel layers; the grinding roller is connected with a support, the millstone is connected with a millstone lining plate, the millstone and the millstone lining plate are provided with through-holes, the two through-holes in the millstone and the millstone lining plate are matched, and the millstone is further provided with a material retaining plate. Both the grinding roller and the millstone adopt double metal layers, surface layers are overlaying welding layers resisting wear very well, and the cast steel layers are arranged inside to resist impacts. Meanwhile, the grinding roller and the millstone have repairability, and overlaying welding can be performed three or four times after the overlaying welding layers acting as the outer layers are worn, so that the cost is remarkably reduced. According to the invention, iron sand at a part, on which iron sand is most likely to gather, in a slag grinding machine can be removed in time, the grindability of slags is improved, the yield is remarkably improved, the wear speeds of a grinding roller lining plate and the millstone lining plate are reduced, and the cost input for the product per ton is lowered.
Description
Technical field
The present invention relates to vertical roller grinder technical field, particularly relate to a kind of wear-resisting mill and grinding roller of slag vertical-mill.
Background technology
Vertical Mill is primarily of transmission device, hydraulic means, powder concentrator and the composition such as mill, grinding roller, and main working parts is mill and the grinding roller doing rolling relatively on mill.Slag vertical-mill charging drops down onto in the middle of mill, form a taper stockpile, along with the rotation of mill, under the influence of centrifugal force, scatter to mill periphery gradually, what enter mill and grinding roller rolls district, finished product after milling or semi-finished product fine powder continue to move to mill edge, form a high outside and low outside oblique charge bank, namely finished product or semi-finished product fine powder enter the outlet of winding-up ring along this slope, under the effect of high speed hot blast, a part upwards enters a point constituency, a part becomes returning charge downwards, because containing iron sand in slag, the proportion of iron is greater than slag, therefore slag or slag powders is compared, the bottom of charge bank is easily deposited in iron sand or the oblique charge bank that formed at mill edge through the iron sand powder that rolls, the i.e. angle that formed of mill blocking material ring and lining board for grinding discs, and the edge being not easily thrown out of mill enters downstream, the iron sand at this place deposits gradually, material grindability is caused to reduce, accelerate lining board for grinding discs, the abrasion of grinding roller liner plate and blocking material ring, field test shows, the wearing and tearing in these places are the most serious.
Summary of the invention
The object of the invention is to solve the deficiencies in the prior art, a kind of wear-resisting mill and grinding roller of slag vertical-mill are provided, the mill that release iron sand deposits in the angle that mill blocking material ring and lining board for grinding discs are formed leaks sand hole structure, the method can make the iron sand be accumulated to herein spill mill fast, improves the life-span of lining board for grinding discs.The structure of mill and grinding roller bilayer, more can improve the service life of mill and grinding roller simultaneously.
The technical solution used in the present invention is: a kind of wear-resisting mill of slag vertical-mill and grinding roller, comprises grinding roller and mill, and the opposite face of described grinding roller and mill is double-decker, and its skin is overlay cladding, and internal layer is cast steel layer; Described grinding roller connection bracket, described mill is connected with lining board for grinding discs, and described mill and lining board for grinding discs are provided with through hole, if two through holes on described mill and lining board for grinding discs are suitable, is also provided with striker plate outside described lining board for grinding discs.
As a further improvement on the present invention, conically, its aperture is less than the aperture of the through hole on mill to the through hole on described lining board for grinding discs.
Further improve as of the present invention, described lining board for grinding discs is combined by some bimetallic secter pats.
The beneficial effect that the present invention adopts is: grinding roller of the present invention and mill all adopt double-metal layer, and superficial layer is overlay cladding, super abrasive; Inside is cast steel layer, shock resistance.There is recoverability simultaneously, after the wearing and tearing of outer overlay cladding, can built-up welding 3-4 time again, cost is significantly reduced.Iron sand is got rid of at the position that in mineral slags bed of the present invention, iron sand is the most easily hoarded in time, improves the grindability of slag, not only significantly improves output, and slow down the rate of wear of grinding roller liner plate and lining board for grinding discs, and the cost reducing ton finished product drops into.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Shown in figure: 1 grinding roller, 2 mills, 3 lining board for grinding discs, 4 backgauge versions, 5 through holes.
Detailed description of the invention
Below in conjunction with Fig. 1, the present invention is described further.
As shown in Figure 1, a kind of wear-resisting mill of slag vertical-mill and grinding roller, comprise grinding roller 1 and mill 2, and the opposite face of described grinding roller 1 and mill 2 is double-decker, and its skin is overlay cladding, and internal layer is cast steel layer; Described grinding roller 1 connection bracket 7, described mill 2 is connected with lining board for grinding discs 3, and described mill 2 and lining board for grinding discs 3 are provided with through hole 5, if two through holes on described mill 2 and lining board for grinding discs 3 are suitable, is also provided with striker plate 4 outside described lining board for grinding discs 3.
Effectively can discharge iron sand in order to ensure the present invention, the operating efficiency simultaneously do not reduced, conically, its aperture is less than the aperture of the through hole on mill 2 to the through hole on described lining board for grinding discs 3.
In order to improve wearability of the present invention further, greatly improved in service life of the present invention, described lining board for grinding discs 3 is combined by some bimetallic secter pats.
Grinding roller of the present invention and mill all adopt double-metal layer, and superficial layer is overlay cladding, super abrasive; Inside is cast steel layer, shock resistance.There is recoverability simultaneously, after the wearing and tearing of outer overlay cladding, can built-up welding 3-4 time again, cost is significantly reduced.Iron sand is got rid of at the position that in mineral slags bed of the present invention, iron sand is the most easily hoarded in time, improves the grindability of slag, not only significantly improves output, and slow down the rate of wear of grinding roller liner plate and lining board for grinding discs, and the cost reducing ton finished product drops into.
Those skilled in the art should know; protection scheme of the present invention is not limited only to the above embodiments; various permutation and combination and conversion can also be carried out on the basis of above-described embodiment; under the prerequisite without prejudice to spirit of the present invention, the various conversion that the present invention carries out all are dropped in protection scope of the present invention.
