With the separation of the material of granular size；
2nd, proportion platform bottom surface is arranged to fish scale orifice plate, to increase material throwing power, controls airflow direction, proportion platform does past
Multiple movement, under airflow function, makes mixed material on proportion platform be in suspended state, and produces vertical and horizontal movement, mixing
Material is different according to proportion, and levels separating effect is well arranged, has vertical inclination angle and back draught in proportion platform and shakes
Under dynamic comprehensive function, make the material after proportion platform higher slice（Light thing is on upper strata, and weight is in lower floor and close to fish scale orifice plate）Production
Raw reverse differential motion, weight do lengthwise movement close to fish scale orifice surface, the discharge end being moved on the right side of proportion platform, top layer
Light thing does counter motion, and the discharge end being moved on the left of proportion platform, realizes the separation of light-heavy material；
3rd, it is arranged at intervals with the demarcation strip being parallel to each other on proportion platform along the longitudinal direction, the length of each demarcation strip is from middle part
Increase successively to both sides so that the separating effect of material is more preferable, and substantially increases the efficiency of feed separation；
4th, proportion platform is vibrating body, has inclination angle with horizontal plane, the size at inclination angle is adjusted by incidence regulating mechanism, unscrews lock
Tight nut, turns adjusting nut so that adjusting nut is moved up along leading screw, by adjusting four groups of tilt adjustment machines
Structure, so as to adjust the inclination angle of proportion platform；
5th, under wind-force effect, according to Gravity Separation principle, separated using thick grain laminar flow regime levels differential counter motion
Technique, by the relatively large material of proportion and the relatively small feed separation of proportion；The size of wind-force directly affects thing with direction
The separating effect of material, the different needs according to the characteristics of material adjust accordingly, and the material that general proportion is small, small will need to be let out
Throttle opening is opened greatly, divides air door that wind-force is divided into front and rear two parts, can control the distribution of proportion platform or so air quantity, practical application
In, it is adjusted flexibly according to the features such as material proportion, volume, until separating optimum efficiency；When mixed material moves on proportion platform
Unstable, light thing separation and reflux unobvious, weight output speed is slow, then shows that air quantity is larger on the left of proportion platform, can be by dividing
Wind regulating device, unscrews the first lock-screw, turns the first adjusting rod so that divide air door to rotate counterclockwise so that proportion platform is left
The air quantity of side part reduces, the air quantity increase of proportion platform right part；When mixed material, stable movement, light thing divide on proportion platform
From with reflux unobvious, weight output speed is very fast, then shows that proportion platform left part air quantity is smaller, can by divide wind adjust dress
Put, unscrew the first lock-screw, turn the first adjusting rod so that divide air door to rotate clockwise so that proportion platform left part
Air quantity increase, the air quantity of proportion platform right part reduce；When mixed material on proportion platform excessively loose, proportion platform right part
Mixed material depth of grain layer is larger, and mixed material conveying speed is slow, and light thing reflux is slow, and apparent specific gravity platform right part air quantity is big,
The second lock-screw can be unscrewed by letting out wind regulating device, turn the second adjusting rod so that draining door rotates clockwise, release more
Lingering remnants of past customs amount；When mixed material conveying speed is fast, light thing separation is poor, shows that proportion platform right part air quantity is small, can be by letting out wind
Regulating device, unscrews the second lock-screw, turns the second adjusting rod so that draining door rotates counterclockwise, increases the wind of proportion platform
Amount.
