Description
Technical field
The present invention relates to the device and application method that a kind of Vertical Mill stablizes the bed of material, belong to Vertical Mill production equipment technology.
Background technology
Vertical Mill is a kind of large-scale milling equipment, is widely used in the industries such as cement, electric power, metallurgy, chemical industry, nonmetallic ore.
It collects broken, drying, grinding, classification are transported in one, and production efficiency is high, bulk, graininess and powder raw material can be worn into institute
It is required that powder raw material.
Vertical Mill work when, motor by gear reducer band movable grinding disc rotate, raw material from feeding mouth fall on mill center, from
Mobile to mill edge and rolled be subject to grinding roller under the action of mental and physical efforts, the raw material after crushing is overflowed from mill edge, coarse powder warp
Returned to after separator sorting on mill, again grinding；Fine powder then goes out mill with air-flow.
Raw material enters Vertical Mill from feeding mouth and falls on mill, and mill under the influence of centrifugal force can in rotary course
Raw material is thrown to the edge of mill, causes the raw material on mill edge thickening, influences the rolling effect and service life of grinding roller, and
And grinding roller is set easily to hit mechanical position limitation.In addition, after raw material on mill edge is thickening, also easily slipped out from mill,
Returning charge is caused to increase.
The content of the invention
It is an object of the present invention to provide the device and application method that a kind of Vertical Mill stablizes the bed of material, original that can uniformly on mill
Material, stablizes the bed of material, improves the rolling effect and service life of grinding roller, reduces returning charge, solves the problems, such as present in background technology.
The technical scheme is that：
A kind of Vertical Mill stablizes the device of the bed of material, includes collet, material scraping plate, grinding roller, mill, feeding mouth, discharge port and vertical mill
Shell, Vertical Mill casing are equipped with feeding mouth and discharge port, are equipped with mill in Vertical Mill casing, mill is equipped with collet, the backgauge
Circle is arranged with mill concentric, and four grinding rollers being in tilted layout, two neighboring mill are symmetrically set on the circumferencial direction of mill
A material scraping plate is equipped between roller, the material scraping plate is right-angled trapezium, and material scraping plate is tilted and is fixed on mill.
Height of the material scraping plate close to mill edge side is more than the height close to mill center side.
Angle is equipped between the radial direction of the material scraping plate and mill.
Feeding mouth on the Vertical Mill casing extends to the top of the center of mill.
The outside diameter of the collet is identical with the diameter of mill.
A kind of Vertical Mill stablizes the application method of bed of material device, is carried out using above device, step is as follows：Raw material is from feeding mouth
Fall on mill, raw material, due to the effect of centrifugal force, can be thrown to the edge of mill, collet can by mill in rotary course
To stop that raw material throws away mill, returning charge is reduced；Material scraping plate can stop raw material before raw material is thrown to mill edge, slow down original
Expect the movement velocity to mill edge, raw material is smoothly taped against on mill.The unnecessary raw material in mill edge passes through material scraping plate meeting
It is reversed and back into mill center, ensures the stabilization of the bed of material.The finished product of grinding is discharged from discharge port, is entered in dust-precipitator.
The beneficial effects of the invention are as follows：Raw material that can uniformly on mill, stablizes the bed of material, improve grinding roller rolling effect and
Service life, avoids grinding roller in process of production and hits mechanical position limitation, while also reduces returning charge.

Fig. 2 is grinding roller and material scraping plate arrangement schematic diagram on mill of the present invention；
Fig. 3 is baffle ring structure diagram of the present invention；
In figure：Collet 1, material scraping plate 2, grinding roller 3, mill 4, feeding mouth 5, discharge port 6.
Embodiment
Below in conjunction with attached drawing, by example, the invention will be further described.
Referring to the drawings 1,2,3, a kind of Vertical Mill stablizes the device of the bed of material, comprising collet 1, material scraping plate 2, grinding roller 3, mill 4,
Feeding mouth 5, discharge port 6 and Vertical Mill casing, Vertical Mill casing are equipped with feeding mouth 5 and discharge port 6, mill 4 are equipped with Vertical Mill casing,
Mill 4 is equipped with collet 1, and the collet 1 is arranged with 4 concentric of mill, is symmetrically set on the circumferencial direction of mill 4
Four grinding rollers 3 being in tilted layout, are equipped with a material scraping plate 2 between two neighboring grinding roller 3, the material scraping plate 2 is right-angled trapezium, is scraped
Flitch 2 is tilted and is fixed on mill 4.
A kind of Vertical Mill stablizes the application method of bed of material device, is carried out using above device, step is as follows：Raw material is from feeding mouth
Fall on mill, raw material, due to the effect of centrifugal force, can be thrown to the edge of mill, collet can by mill in rotary course
To stop that raw material throws away mill, returning charge is reduced；Material scraping plate can stop raw material before raw material is thrown to mill edge, slow down original
Expect the movement velocity to mill edge, raw material is smoothly taped against on mill；The unnecessary raw material in mill edge passes through material scraping plate meeting
It is reversed and back into mill center, ensures the stabilization of the bed of material.The finished product of grinding is discharged from discharge port, is entered in dust-precipitator.
In the present embodiment, the outside diameter of collet 1 is identical with the diameter of mill 4, and the height of collet 1 is 300mm, backgauge
