Abstract
The invention discloses a grinding table for a slag vertical mill. The grinding table for the slag vertical mill consists of a grinding table body, a lining plate and a material blocking ring, wherein a grinding table hole and a lining plate hole are respectively reserved at the outer ends of the grinding table body and the lining plate. By using the grinding table for the slag vertical mill, iron sand is removed timely from the position, where the iron sand is easiest to hoard, in a slag abrasive bed, so that the grindability of slag is improved; the yield is improved remarkably; moreover, the wear speed of the lining plate of a grinding roller and the lining plate of the grinding table are slowed; and cost input of each ton of finished products is reduced.
Description
Technical field
The present invention relates to the vertical roller grinder technical field, specifically be a kind of mill of slag Vertical Mill.
Background technology
The charging of slag Vertical Mill drops down onto in the middle of the mill, form a taper stockpile, rotation along with mill, under action of centrifugal force, scatter to the mill periphery gradually, enter the district that rolls of mill and grinding roller, finished product after milling or semi-finished product fine powder continue to move to the mill edge, form a high outside and low outside oblique charge bank, finished product or semi-finished product fine powder promptly enter the outlet of winding-up ring along this slope, under the effect of high speed hot blast, a part upwards enters the branch constituency, and a part becomes returning charge downwards, because contain iron sand in the slag, the proportion of iron is greater than slag, therefore compares slag or slag powders, and the iron sand powder that iron sand or process roll is deposited on the bottom of charge bank easily in the oblique charge bank that the mill edge forms, it is the angle that mill blocking material ring and mill liner plate form, and the edge that is difficult for being thrown out of mill enters next flow process, and the iron sand at this place deposits gradually, causes the material grindability to reduce, quicken the mill liner plate, the abrasion of grinding roller liner plate and blocking material ring, field test show that the wearing and tearing in these places are the most serious.
Summary of the invention
The mill that a kind of slag Vertical Mill is provided of the present invention is exempted iron sand and is leaked the sand hole structure at the mill of the angle deposition of mill blocking material ring and the formation of mill liner plate, and this method can make the iron sand that is accumulated to herein spill mill fast, improves the life-span of mill liner plate.
The present invention is that the technical scheme that the deficiency that solves the problems of the technologies described above adopts is: a kind of mill of slag Vertical Mill, form by mill body, liner plate and blocking material ring, mill body and liner plate outer end are provided with mill hole and liner plate hole respectively, mill hole and liner plate hole communicate, and aperture, mill hole is greater than the aperture in liner plate hole.
Liner plate of the present invention hole is the back taper type.
The external end of mill of the present invention is evenly distributed with the mill hole along circumference, and the outer end of liner plate is evenly distributed with the liner plate hole along circumference.
The invention has the beneficial effects as follows:
1, the present invention makes the position that iron sand is the most easily hoarded in the mineral slags bed get rid of iron sand in time, has improved the grindability of slag, has not only significantly improved output, and has slowed down the rate of wear of grinding roller liner plate and mill liner plate, has reduced the cost input of ton finished product.
2, expect that a timely eliminating of going up iron sand has improved the nonferromagnetic substance of material bed greatly, optimizes the Vertical Mill runnability more.
3, owing to the iron sand that releases from the leakage sand hole is removed by the tramp iron separator on the return conveyer, the iron sand of only collecting every day just reaches several tons, has increased extra income, improves the slag utilization rate.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure: 1, mill body, 2, liner plate, 3, grinding roller, 4, the discharge ring, 5, the winding-up ring, 6, the mill hole, 7, the liner plate hole.
The specific embodiment
As shown in the figure, a kind of mill of slag Vertical Mill, form by mill body 1, liner plate 2 and discharge ring 3, mill body 1 and liner plate 2 outer ends are provided with mill hole 6 and liner plate hole 7 respectively, and mill hole 6 and liner plate hole 7 communicate, and the aperture in its mill hole 6 is greater than the aperture in liner plate hole 7, mill body 1 is connected with liner plate 2, discharge ring 3 is arranged on the outer circumference surface of mill body 1 and liner plate 2, and discharge ring 3 peripheries are provided with winding-up ring 5, and liner plate 2 upper end correspondences are provided with grinding roller 3.
Described liner plate hole 7 is the back taper type.
Described mill body 1 outer end is evenly distributed with mill hole 6 along circumference, and the outer end of liner plate 2 is evenly distributed with liner plate hole 7 along circumference.
Raw materials of slag enters mill 1 central authorities through revolution lock feeding valve.Mill rotates under the drive of main motor, main gear reducer, and material moves to mill 1 periphery under action of centrifugal force, enter between grinding roller 3 and the liner plate 2, through paving, behind the grinding, from the discharge of mill periphery.
Be provided with winding-up ring 5 at the mill periphery, thermal current enters by periphery winding-up ring 5, carries the material that mill body 1 periphery is discharged, and rotation is risen, and the bulky grain of wherein can not being with settles down, and is discharged by slag-drip opening; Small particles material is deposited in uphill process on the liner plate 2, and fine grained enters powder concentrator with air-flow and carries out sorting, and qualified thin material is taken grinding machine out of with air-flow, and underproof thick material returns mill 1 and continues grinding.
Iron sand in the slag is through after rolling, because proportion is big than slag, be deposited in the blocking material ring 4 of mill and the angle that liner plate 2 forms, the liner plate hole 7 of opening some far from the place that blocking material ring formation iron sand is piled up at liner plate 2 edges, big end is following, small end up, can guarantee that like this material that does not have bulk is stuck in the hole, and on the mill body 1 under the liner plate 2, bore nog plate hole 6 greater than big stomidium size with corresponding positions, liner plate hole 7, make the higher slag of the iron sand content be piled up in mill edge major part in the flowing of the extruding of grinding roller 3 and material from the hole, release like this, enter return conveyer, the tramp iron separator that final iron sand is arranged on the return conveyer is removed, and the slag of removing iron sand can be gone into mill once more and be ground, finish the deironing task, thereby reduce the wearing and tearing of liner plate 2, improve nonferromagnetic substance, increased economic benefit.
