Excess material, the second sorting outlet 132 of 602 top of lower part uniform device is for being discharged coarse granule product.In addition, feeding inlet 122 is set
On the top of column body section 101, rather than the top of lower prop section 102.
The change of 122 position of feeding inlet is so that great change has occurred in assorting room inside sorting machine: for scheme before,
After pan feeding particle enters the column body section 101 of sorting machine, partial intermediate and most light fine graineds are in column body section 101
Interior realization fluidization, distributes raw isolation layering, and most coarse particles and partial intermediate particle are then uniformly distributed across top
Isolation layering occurs in lower prop section 102 for device 601 and transition-cone section 103.And feeding inlet 122 is changed to lower prop section 102
Behind top, the particle in pan feeding is first into lower prop section 102, and coarse particles therein and intermediate product particles are real first
Existing fluidization, and partial intermediate particle and the light fine grained of the overwhelming majority are then brought into column body section with ascending fluid medium
In 101, since 101 area of passage of column body section is big, ascending fluid medium velocity is reduced, among the part in column body section 101
Component particles and light fine grained realize fluidization and gradually isolation layering, feed speed by adjusting fluid in top uniform device 601
The control to beds properties such as 101 endoparticle fluidized-bed layer porosity of column body section and apparent densities then can be achieved in rate.If mesh

Make to scan after the roughing of sorting material elder generation, is conducive to improve the target minreal rate of recovery；If target minreal is mostly in light fine grained
Component, then being equivalent to by the feeding inlet of alternative solution on the top of lower prop section 102 makes selected after the roughing of sorting material elder generation, benefit
It is sampled in improving target minreal.And press for feeding inlet position proposed by the present invention, when target minreal is distributed mainly on big and heavy
Grain organizes timesharing, and being equivalent in column body section 101 makes pan feeding first carry out one roughing, then completes in lower prop section 102 primary
It is selected, be so conducive to improve target minreal taste in product；When target minreal is distributed mainly on light fines fraction, upper prop
Being equivalent in body section 101 makes pan feeding first carry out one roughing, then completes once purging selection in lower prop section 102, is conducive to mention
High density mineral recovery rate.
In summary three embodiments, traditional fluidization screening installation realize material by the variation of monitoring bed layer pressure
Automatic-discharging, the disadvantages of this control system delays in the presence of control, and precision is not high, in addition, after pan feeding property changes
(such as feed thickness, pan feeding speed and material size composition), the bed layer pressure value and new charged material property originally set is not
