Lifting lug 4 is equipped between two blocks of side plates 3.
The quantity of the sieve 5 be it is multiple, two layers about 5 uniform intervals of sieve setting, multilayer sieve is sieved, raising
Screening effect guarantees ore sizing grade and quality, improves product competitiveness.
In use, three phases of the ore in sieve, region:
First stage and region: accumulative phase (feeding zone)；When ore falls to above barrow band to vibrating screen upper layer
It is the blanking region of vibrating screen when sieve；One side blanking region ore storage accumulates thicker, upper layer about 250mm~300mm, under
Layer about 160mm~220mm；" screenable particle " (particle that ore grain size is less than sieve pore 3/4) and " near mesh particle " are (between sieve pore at this time
And 3/4 particle between sieve pore) be not easy through ore layer；On the other hand since ore is thicker, weight is big, ore vibration below
It can not move, the speed of forward impelling is most slow；This region is the screening effect most bad stage, and sieve pore is easy to block, " easily
Sieve grain " can sieve lower 5% or so, and " near mesh particle is almost nil, and screening efficiency is 5% or so；This region accounts for about the 1/ of cover surface
7 and vibrating screen top, this region screen size selects slightly larger preferable (depending on actual production), and sieve pore is small
It is easy blocking.
Second stage and region: loose stage (diffusion region)；Under the action of ore is by vibration or gravity, according to installation
Angle downwards and two sides are when slowly spreading, the two sides for being diffused into vibrating screen always just stop spreading, this stage is that handle is accumulated
Ore be loosened, ore layer starts to isolate, and ore thickness is slightly more thinner than the first stage, upper layer about 200mm~250mm, under
Layer about 150mm~200mm；This stage ore Oscillation Amplitude starts to increase, and ore fltting speed starts to accelerate；This region is about
The 1/4 of vibrating screen area is accounted for, " screenable particle " and " near mesh particle " starts through ore layer at this time, and it is left that " screenable particle " can sieve lower 36%
The right side, " near mesh particle " can sieve lower 4~6% (this portioned product is unqualified), and screening efficiency is 36% or so；In order to guarantee grade, institute
With the selection of this region sieve screen size sieve more slightly smaller than the first stage, but can not be too small, being not easy to plug is advisable.
Phase III and region: continuous-stable propulsion phase (screening area)；When ore is diffused into vibrating screen two sides, ore
Blocked by the side backplate of vibrating screen two sides to spread toward two sides again, (downward) forward can only walk, on the surface, ore is
It continuously walks forward, downwards along a rectangular region, this partial region area is bigger, is the main screening of vibrating screen
Region accounts for about the 3/5 of the compass screen surface gross area；In this stage, with sifting out for qualified ore, qualified products are fewer and fewer, ore
Thickness is also more and more thinner (upper layer about 100mm~150mm, lower layer about 100mm~150mm), the amplitude and walking speed of ore vibration
Degree reaches maximum and stablizes, and " screenable particle " can sieve lower 50% or so, " near mesh particle " can sift out 85% or so (this part have qualification with
Substandard product), screening efficiency is the best region of screening effect 55% or so；But substandard product is easy for from this
A region is sifted out, so the sieve that the selection of this region sieve screen size is more slightly smaller than second stage, avoids unqualified production
Product are more and influence grade.
The sieve of vibrating screen chooses whether the height for rationally directly influencing screening efficiency, grade and yield；To screening
Excellent in efficiency, it is necessary to increase the area of sieve pore, but sieve pore is excessive and influences product quality (grade), this is very contradictory；According to
It was verified that selection rectangle sieve pore not only increases the area of sieve pore, prevents sieve pore blockade, and screening efficiency is high, sifts out
As long as the thickness of product particle will not influence the rate of recovery and grinding efficiency of production lower than 9mm；But the area that vibrating screen is different
The sieve pore in domain, selection is also different, and the screen size of different sieves is selected according to three regions of the material on sieve.
Learn that the selection empirical equation of screen size is as follows according to practice: qualified products width and length dimension d × c
(mm) (d is the diameter of standard ore, and c is mesh-length) is referring to following table:
The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry
It should be appreciated that the present utility model is not limited to the above embodiments, the above embodiments and description only describe this
The principle of utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model also has various change
And improvement, these various changes and improvements fall within the scope of the claimed invention.The utility model requires protection scope
It is defined by the appending claims and its equivalent thereof.
