Description
Technical field
The present invention relates to the powder ball-milling device technical fields of high fineness, are specially a kind of ball prepared for nano silica fume
Mill apparatus.
Background technology
Nano level silica flour is indispensable material for preparing nano silica-magnesia solid state battery, nano level powder
Last fineness, further battery performance is even more promoted, which to play, has decisive role, however in the prior art, ball mill is material
After broken, then the key equipment crushed, extensively using with the production industries such as non-ferrous metal ore, existing ball mill one
As internal steel ball is promoted using centrifugal force when rotating, powder is carried out to material by the interaction between steel ball and material
It is broken.Sphere is generally made up of metal or nonmetallic materials, is rotated with ball mill barrel, abrasive body in cylinder again and again
It the movements such as turns round, leave, rolling, sliding, being formed between abrasive body and material by impact, rubbing action and transfer energy, led to
It crosses and smashes, grinds mode comminuting matter, and existing abrasive body is impacting, since surface is smooth in friction process, most energy
Amount is not utilized, and change thermal energy, acoustical energy losses are fallen, the effective rate of utilization of energy is very low, is only 1~3%, and ball milling is electromechanical
Consumption is high, and ball mill barrel is also fragile, has plenty of the use longevity that simple wear-resistant liner is added in machine barrel to extend machine barrel
Life.
The surface that wear-resistant liner is whether completely smooth, is still cast with some decorative patterns on the surface, it carries abrasive body
The effect of liter is essentially all by the stiction between liner plate and abrasive body, and the confficient of static friction of ball mill by wet process is 0.35,
The confficient of static friction of dry method ball mill is 0.4, since confficient of static friction is more much smaller than actual needs, so inevitably
There is the phenomenon that abrasive body slides, cause the reduction of liner plate hoisting depth, the abrasion increase of liner plate and sphere reduces ball mill
Grinding efficiency increases the abrasion of liner plate.In addition, in existing ball mill, bulky grain, middle particle, short grained material are all
It mixes, is ground by a kind of steel ball, not only spend the time long, and the effect of ball milling is nor very well, it can be with
Reach and silica flour is ground into nano level fineness, reach the nanoscale demand for meeting nano silica-magnesia battery production raw material.
The content of the invention
To solve the above problems, the invention discloses it is a kind of for nano silica fume prepare ball-milling device, not only ball milling imitate
Fruit is good, Ball-milling Time is short, and extends the service life of liner plate, operates steadily, and can reach silica flour being ground into nanometer
The fineness of grade, reaches the nanoscale demand for meeting nano silica-magnesia battery production raw material.
To achieve the above object, the present invention provides following technical solution：
A kind of ball-milling device prepared for nano silica fume, including cylinder, the cylinder both ends are equipped with material inlet and object
Material outlet, the inner barrel are equipped with first partition and second partition, were equipped on first partition plate and second partition
Filter opening, the filter hole aperture on first partition plate are more than the filter hole aperture on second partition, the first partition and the
Cylinder is divided into the first cylinder, the second cylinder and the 3rd cylinder by two partition plates, first cylinder, the second cylinder and the 3rd cylinder
It is equipped with wear-resistant liner on inner wall, protrusion, first cylinder, is equipped on the liner plate of first cylinder and the second cylinder
Grinding steel ball of different shapes is contained in two cylinders and the 3rd cylinder respectively, first in vivo steel ball body is circle
Cylindricality, the upper end and bottom of the cylinder steel ball body are connected to circular arc-shaped end, second in vivo steel ball
Surface has multiple protrusions.
Further, the height of the protrusion protrusion on first cylinder and the second shell liner is 4cm.
Further, the height of described second in vivo steel ball surface protrusion is 4cm.
As further embodiment of the present invention, the cross sectional shape of second in vivo steel ball surface protrusion is trapezoidal.
Compared with prior art, the beneficial effects of the invention are as follows：
It is designed by innovation research,：Protrusion on liner plate can be by steel ball band
To peak, add the impact force that particle surface is subject to, ball milled ingredients faster, the time it is short, and extend lining
The service life of plate；Different size of particle is separated into ball milling, ball milling effect is more preferable；Meanwhile it can reach and be ground into silica flour
Nano level fineness reaches the nanoscale demand for meeting nano silica-magnesia battery production raw material.

Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, and the present invention is furture elucidated with reference to the accompanying drawings and detailed description, it should be understood that following specific embodiments are only
For illustrating the present invention rather than limiting the scope of the invention.It should be noted that word " preceding " used in the following description,
" rear ", "left", "right", "up" and "down" refer to the direction in attached drawing, and word " interior " and " outer " refer respectively to direction or remote
Direction from particular elements geometric center.
As shown in the figure, a kind of material ball-milling device, including cylinder 1,1 both ends of cylinder are equipped with material inlet 2 and material outlet
3, cylinder 1 is internally provided with first partition 7 and second partition 8, is equipped with filter hole on first partition plate 7 and second partition 8, and first
7 filter hole aperture is more than the filter hole aperture on second partition 8, first partition 7 and second partition 8 by cylinder point on a partition plate
For the first cylinder 4, the second cylinder 5 and the 3rd cylinder 6, large, medium and small three kinds of particles are held respectively, 7 filtering on first partition plate
Hole can allow middle particle and small particles material by the way that large granular materials is prevented to pass through；Filter hole on second partition 8 can allow small
Granule materials pass through granule materials in prevention.
Wear-resistant liner 9, the first cylinder 4 and second are equipped on the inner wall of first cylinder 4, the second cylinder 5 and the 3rd cylinder 6
Protrusion 10 is equipped on the liner plate of cylinder 5, the height of the protrusion protrusion on the first cylinder and the second shell liner is 4cm.
Abradant steel ball of different shapes is contained with respectively in first cylinder 4, the second cylinder 5 and the 3rd cylinder 6, in cylinder
During body rotates, protrusion can be by steel ball band to peak whereabouts grinding material.Since the material in the first cylinder 4 is big
Particle, so being cylinder by the body design of first in vivo steel ball 11, the upper end and bottom of cylindrical steel ball body are divided
Circular arc-shaped end 111 is not connected with, and which increases the contact area of steel ball surface and material, ball milling effect is more preferable；Second
It is middle granule materials in cylinder 5, need to only has multiple raised 13 to can be realized well on 12 surface of steel ball in the second cylinder 5
Ball milling effect, the raised cross sectional shape is preferably trapezoidal, and the height of second in vivo steel ball surface protrusion is 4cm；3rd
Cylinder 6 is small particles material, the steel ball that the steel ball 14 in the 3rd cylinder 6 need to use surface smooth.
