Description
Technical field
The utility model relates to vertical roll grinder fields, and in particular to a kind of mill component of vertical roll grinder.
Background technique
Material slag, the steel slag of vertical roll grinder are that (there is grinding roller on surface with grinding roller by mill (there is lining board for grinding discs on surface)
Liner plate) between roll and crush, the material slag of vertical roll grinder, steel slag are delivered to mill center through screw conveyor, grind
Material in disk center is completed at the same time under the influence of centrifugal force around the circumferential movement at mill center and along the outside of mill radial direction
It is moved into abrasive areas, while mill circle side is equipped with blocking material ring, material is made to form grinding bed on mill, in slag, steel slag
Containing iron sand, and iron is a kind of both hard substance with certain ductility, and grindability is very poor, under the rolling repeatedly of grinding roller
Its granularity is also not easy to reduce, and iron sand or the iron sand powder by rolling are easy to be deposited in backgauge in the oblique charge bank that mill edge is formed
At ring, i.e. the region that is formed of mill blocking material ring and lining board for grinding discs and grinding roller liner plate, and be not easy selected powder and enter downstream, simultaneously
Constantly there is the iron particle newly entered to be detained again, the iron particle quantity in the final region is cumulative, the height of grinding roller big end
A large amount of tiny iron filings accumulations in mill working area are pressed, so that grinding roller outer rim, lining board for grinding discs and blocking material ring abrasion aggravation, in the short time
Just it is ground with deep groove, scene operation shows that the abrasion in the region is the position of most serious in vertical roll grinder, therefore removes iron
Effect quality has a major impact the service life of wearing piece and the mill efficiency of Vertical Mill.
Utility model content
The purpose of the utility model is to provide a kind of mill components of vertical roll grinder, are acted on by mill centrifugal force by iron
Sand is thrown away outside blocking material ring from sand losing opening, can either be reduced the rate of wear of lining board for grinding discs and grinding roller liner plate, be prolonged the service life,
It can be improved the mill efficiency of Vertical Mill again.
A kind of in order to solve the above technical problems, the technical scheme adopted by the utility model is: mill of vertical roll grinder
Component, including mill body, lining board for grinding discs and blocking material ring, lining board for grinding discs lower end are embedded the middle part in mill body upper surface, mill lining
The periphery of plate upper end forms annular notch, and the bottom surface of annular notch is concordant with mill body upper surface, and blocking material ring is fixedly connected on mill
On disk body, around lining board for grinding discs, blocking material ring has multilayer and arranges from the bottom to top, and every layer of blocking material ring is by several scallops
The ring-type of part annular array composition, wherein only forming sand losing opening between the fan-shaped part of composition lowest level blocking material ring, sand losing opening is in
Inner small and outside big is horn-like.
Every layer of blocking material ring is preferably made of 6-10 fan-shaped part, can be specifically made of 8 fan-shaped parts.
The utility model has the advantages that
1, the utility model (most easily accumulates at iron sand on corresponding mill periphery) setting sand losing opening at lowest level blocking material ring, and
It is acted on by mill centrifugal force and iron sand is thrown away outside blocking material ring from sand losing opening and (throws away mill), propose grinding material grindability
Height, operation is more stable, while iron block reduction makes vertical roller grinder machine vibration decline to a great extent, and operational effect is obvious, and unit-hour output is aobvious
It writes and improves；
2, sand losing opening is provided on blocking material ring, compared to being provided on mill and lining board for grinding discs, has significant advantage:
(1) sand losing opening is provided on blocking material ring, processes relatively convenient, and the aperture of mill body and lining board for grinding discs is complex, is processed into
This higher, either aperture of lining board for grinding discs or the aperture of mill body, the separable processing cost of the two are significantly larger than backgauge
The processing cost of ring, still more the two processing cost summation；(2) since lining board for grinding discs is vulnerable part, the frequent heap in grinding is needed
Plane on lining board for grinding discs is welded, is easy to block or leakage sand hole is made to become smaller leakage sand hole during built-up welding, influences to leak husky effect
Fruit；(3) it is easy putty through aperture on real-world effectiveness lining board for grinding discs, just under grinding roller of vertical mill, grinding roller is rolling material for aperture
In the process, since material contains moisture content and the top Yi Kong is hardened, leakage sand hole is plugged, and is provided on blocking material ring and is then not present
This states situation；(4) if in mill body and lining board for grinding discs aperture, both hole must up and down to just, be easy to appear casting miss
Difference, if hole has dislocation iron sand will be caused smooth can not to flow out between lining board for grinding discs and mill body；(5) aperture on lining board for grinding discs
Structure, lining board for grinding discs are easier to split from tapping under the action of roller pressure, gradually by roller pressure and gradually by initial microgroove
Flaring exhibition causes liner plate to crack, and is provided on blocking material ring and then states situation there is no this；
3, sand losing opening is formed by the gap between fan-shaped part, rather than the aperture directly on fan-shaped part, structure letter
List, process are few, easy to produce；
4, on the one hand sand losing opening is not easy to be blocked by iron sand, on the other hand can reduce iron sand in inner small and outside big horn-like
Shock and abrasion to sand losing opening hole wall, to extend the service life of blocking material ring；
5, the periphery of lining board for grinding discs upper end forms annular notch, and the bottom surface of annular notch is concordant with mill upper surface, can allow
The iron sand of accumulation is efficiently discharged at faster speed；
6, the utility model can significantly slow the mill of grinding roller liner plate, lining board for grinding discs and blocking material ring by throwing away iron sand
Speed is damaged, extends the bulk life time of wearing piece, while the repairing built-up welding interval time of user's opposite grinding roll sleeve and lining board for grinding discs
Elongated, the maintenance Vertical Mill time shortens, and reduces the investment of cost, and then increase economic benefit；The iron thrown away from blocking material ring
Sand collects iron sand after material scraping plate scrapes, through iron remover, can be that user increases extra returns as by-product；In grinding process
The mill efficiency that vertical roll grinder is not only increased after the scum being enriched on mill is removed, grinding pow consumption is substantially reduced.
