It is saved to transport powder product and be packed into storage room.
Large-scale grinder, which is usually matched, is arranged with continuity blanking device, so that continual attrition process is maintained, but very
The ore raw materials granular size provided when more is inconsistent, some feed particles are excessive, will lead to it and processes not in grinder
Sufficiently, processing efficiency and product quality are finally influenced, it is therefore desirable to be sieved before blanking, reject the underproof original in part
Material.Existing screening plant is usually rotary screen or shaking screen, is that passing through for particle is screened using the size of sieve pore.But
This screening plant has certain problems: first is that efficiency of screen out is low when the face of screening is lesser, being easy to happen blocking etc.
Problem influences raw material addition；Second is that sieve diameter is fixed, the particle demand of raw material be added can not be adjusted in time, is not adapted to
Modern intelligent grinder.
Utility model content
For the deficiency in the presence of the prior art, the utility model provides screening separator under a kind of grinding host,
To solve efficiency of screen out present in screening plant in existing grinder it is low, be easy blocking and sieve pore fix, can not adjust
The problem of saving screening requirements.
To achieve the above object, the utility model uses the following technical solution:
Screening separator under a kind of grinding host, including the feed pipe, screening machine and discharge nozzle set gradually from top to bottom,
Wherein screening machine upper and lower ends opening is connect with feed pipe, discharge nozzle, and screening machine side is additionally provided with the feed back pipe tilted down；Also
Including the elevating conveyor being vertically arranged, described elevating conveyor one end is connect with feed back pipe, and the other end is connected with Material disintegrator, institute
The outlet for stating Material disintegrator is connected to the side of feed pipe；
The screening machine includes the impeller of cylindrical housing and coaxial arrangement inside the housing, and the impeller is located at feed pipe
Perpendicular to feed pipe, the lateral surface of the shell is respectively equipped with three openings and feed pipe, goes out the rotation axis of underface and impeller
Expects pipe and feed back pipe connect one by one, the diameter of the impeller matched with the diameter of shell can covering shell rounded face and from
By rotating.
Compared with the prior art, the utility model has the following beneficial effects:
1, the utility model is sieved by the impeller being arranged perpendicular to feed pipe, and there is no sieves where sieve pore for impeller
The problem of except plane, therefore in the case where the face of screening is small, screening efficiency is impacted little, can greatly improve screening efficiency,
The case where will not resulting in blockage, reduce maintenance time and cost；
2, the velocity of rotation of impeller is adjustable in the utility model, can compared to the sieve plate and sieve of fixed sieve diameter
With granular size sieved required for more free adjustment, to cooperate, different grinders is configured and different revolving speeds comes
Most reasonable arrangement is carried out, the powder product of better quality is obtained；
3, the impeller side of the utility model is additionally provided with feed back pipe, so that the unqualified raw material sifted out is discharged, then passes through
Elevating conveyor member, which is dredged, to be re-worked in Material disintegrator and is back in feed pipe, can handle unqualified raw material with automatic cycle,
Improve Raw material processing efficiency.

Specific embodiment
The technical solution in the utility model is further illustrated with reference to the accompanying drawings and embodiments.
Embodiment:
As shown in Figure 1-3, the utility model proposes screening separators under a kind of grinding host, including from top to bottom successively
Feed pipe 1, screening machine 2 and the discharge nozzle 3 of setting, wherein 2 upper and lower ends of screening machine opening is connect with feed pipe 1, discharge nozzle 3,
Feed pipe 1 and discharge nozzle 3 are collinearly arranged in the present embodiment, so that the upper and lower ends opening of screening machine 2 is oppositely arranged, raw material can be with
It falls along the vertical direction, does not fall off and be skewed off to elsewhere.
2 side of screening machine is additionally provided with the feed back pipe 4 tilted down in the utility model, in preferred scheme, feed back pipe 4 with
The angle of discharge nozzle 3 is 30~60 °, and the present embodiment is 45 °, is returned for that will screen underproof raw material.The utility model is also
Including the elevating conveyor 5 being vertically arranged, described 5 one end of elevating conveyor is connect with feed back pipe 4, and the other end is connected with Material disintegrator
6, the outlet of the Material disintegrator 6 is connected to the side of feed pipe 1；Therefore the unqualified raw material sifted out can be discharged, then passed through
