Degree differs, thus height when contacting with shaft screen 4 is the most different, and the whole short transverse along shaft screen 4 has material to be distributed, thus
To the impact of shaft screen 4 with wear and tear relatively small, shaft screen 4 is not easy to get stuck, and screening effect is good, the extension device life-span;And in taper
The centrally disposed boss in hole 101, it is to avoid material falls into bellmouth 101 bottom centre and causes the problem of material grinding effect difference,
Also the structural strength of centrifugal mill 1 is improved;It addition, bellmouth 101 hole wall surrounding is evenly arranged with abrasion-proof rib 102, it is ensured that material
Rotate with centrifugal mill, it is achieved material mutually clashes into friction, reach the effect of crushing grinding.
Further, throw away centrifugal mill 1 to height different when contact with shaft screen 4 surface according to material, control from
The tapering of the bellmouth 101 of reduction dish 1, in the range of 90 °~150 °, is to consider the diameter of centrifugal mill 1 and required
Shaft screen 4 diameter and highly obtaining, is conducive to controlling instrument size and production cost, in short transverse is distributed when material flies out simultaneously
The most uniform, in the present embodiment, the tapering of this bellmouth 101 selects 120 °.Meanwhile, the profile of abrasion-proof rib 102 is strip
Shape, material, along the generatrix direction of bellmouth 101, is stirred in centrifugal mill 1 rotation process, makes thing by its length direction
Expect mutual collision friction, i.e. produce autogenous grinding campaign, reach grinding effect.
Embodiment 2
A kind of vertical centrifugal of the present embodiment grinds disintegrating machine, and substantially the same manner as Example 1, difference is: such as Fig. 4
Shown in, the profile of the abrasion-proof rib 102 on the hole wall of the bellmouth 101 of described centrifugal mill 1 is arc, its direction of rotation with from
The rotation direction of reduction dish 1 is identical, uses the abrasion-proof rib 102 of arc to compare the mixing effect to material of strip more preferably, more
Be conducive to the mutual collision friction of material, improve crushing grinding effect, and can extend between material flies out and contact with shaft screen 4
Time, be conducive to increasing the height that material flies out.
Embodiment 3
A kind of vertical centrifugal of the present embodiment grinds disintegrating machine, and substantially the same manner as Example 2, difference is, this reality
Executing example to be improved the shape of shaft screen 4, the most as shown in Figure 5 and Figure 6, the shape of cross section of shaft screen 4 is polygon, preferably
The shape of cross section of shaft screen 4 is regular pentagon, regular hexagon or octagon, selects regular hexagon in the present embodiment.
In existing grinder, screen cloth is generally cylindrical, this kind of structural materials fly out from centrifugal mill 1 after velocity attitude
With screen cloth anon-normal to contacting, having and necessarily cut angle, raw meal particle size ability smaller than screen cloth mesh must pass through screen cloth, thus leads
Product granularity obtained by cause is less than design granularity, and easily gets stuck, and this equipment uses shape of cross section to be polygonal cylinder
Sieve 4, by controlling centrifugal mill 1 rotating speed, with the respective face almost perpendicular contact of shaft screen 4 major part material can be made to fly out after,
Thus the raw meal particle size filtered out is basically identical with the slot size of shaft screen 4, is i.e. consistent with design, products obtained therefrom particle size uniformity
Good.
