Description
Technical field
The present invention relates to powder concentrator device field, is specially a kind of special powder concentrator of sandstone.
Background technology
Powder concentrator is to aim at sandstone roll squeezer or the matching used static rank bale breaking equipment of ball mill, roll squeezer or ball milling
The material particles distribution that machine crushes out is very wide, after selecting powder by powder concentrator, can be directly obtained into by fine grained first at sorting
Product, and bulky grain goes successively to roll squeezer or ball mill is crushed again.Since fine grained is separated in advance, enter
The material particles of roll squeezer or ball mill are more uniformly neat, and the mill efficiency of system greatly improves, and is conducive to roll squeezer or ball
The even running of grinding machine, improves system throughput, and has drying function.At present, in building materials and metallurgy industry, powder concentrator is due to it
Have material scattering, drying, the function of classification concurrently, various grinding process systems can be formed with equipment such as roll squeezer or Vertical Mills,
Building materials, cement industry are widely used.
Sand material accounts for 80% of weight concrete or so in concrete, therefore Preservation for Aggregate Production System is weight prepared by concrete
Core is wanted to form, and technology for making sand is then the core process in sandstone processing, existing technology for making sand is that sandstone is passed through pressure roller
Machine pressure roller, then selects powder through powder concentrator, selects the sand powder of qualification.Supplied materials flow, content of stone powder, the moisture content of roughing sand are all shadows
An important factor for powder concentrator selects powder ability and selects powder effect is rung, when feeding moisture content 2%, powder concentrator can effectively play it
Efficiency, stone powder padding efficiency is preferable, recycles the particle size content of mountain flour（More than 0.16mm）During less than 15%, it can meet successive projects
Mountain flour need.There are problems with when in use for the existing special powder concentrator of sandstone：Water content be higher than 2% when, material easily into
Stick together, when falling within into the material to stick together on bulk cargo vertebra, sandstone is not easy to be thrown scattered, and fine powder is not easy to be entrained by the flow of air, and has seriously affected point
Select effect.In the prior art high-water content sandstone is dried or excludes in order to control the water content of charging generally to be concentrated using raw material
Heap, causes the waste of raw material using these measures and extends the working time.Therefore a kind of special powder concentrator of sandstone is continued, effectively
The higher sandstone material of processing water content, improve selection by winnowing effect.
The content of the invention
To solve the above problems, the invention discloses a kind of special powder concentrator of sandstone.
In order to reach object above, the present invention provides following technical solution：

The water content for obtaining material reaches predetermined requirement；It is indoor in selection by winnowing can also to extend material for the setting of burden-guiding cone and heating cone at the same time
Residence time, accelerates the drying of material；Material is fallen subsequently into spiral bulk material device, is radially got rid of under the influence of centrifugal force
Go out, air-flow of the material with upper rotation in separating chamber meets, the fine grained in material because quality is small and with air-flow rise via with turn
The rotating grizzly bar classification of son, qualified fine powder continue to ascend into cyclone dust collectors, are fallen into after cyclone cylinder is collected through grizzly bar
Exported to the ash bucket of deduster from fines outlet pipe；Remove the air after fine powder and then return to wind turbine formation gas from deduster through air hose
Flow closed cycle；Coarse granule because quality it is larger under the action of spiral bulk material device with thin feed separation, whereabouts, from coarse fodder outlet pipe
Discharge.
Beneficial effects of the present invention：1st, the setting of heating cone and heater is reasonable, accelerates the drying to material, ensures aqueous
Amount is less than 2% so that powder concentrator can effectively play its efficiency, and stone powder padding efficiency is preferable；2nd, the cooperation of burden-guiding cone and heating cone
Set, extend material in the selection by winnowing indoor residence time, on the one hand may be such that material dispersion evenly, on the other hand may be such that thing
Expect that rate of drying is accelerated；3rd, selection by winnowing effect is good, and sandstone effectively sorts, and grinding efficiency is high, and particle size range is small, effectiveness of classification is high.
