Structural principle

The artificial sand size range 0~4.75mm is produced by crusher,sand making machine,vibrating screen enters the scattered area through the feeding port of the machine by conveying equipment enter into disperse zone.Under the action deflectors and impact plates,sand particles with different particles sizes is separated at different gravity velocity.There are several relative friction between sand grains,the mud powder and stone powder on the sand surface are stripped off;surface of sand is removed easily via air flow.Thus,the desired sand product is cleaned.

The materials feed from inlet are scatter and peeled off by multi-stage deflector plates.The air flow from left end side between the deflector plates carry the coarse and fine materials into the material stream.The coarse sand is discharged from the coarse sand outlet point located at bottom of the unit.Materials are suspended in the air flow enter the multi-layer grading plate 5 and perform classifications.The grading plates further remove relatively coarse materials from the air flow,coarse material will slide down with air counter flow repeated process.Then air flow into middle classification zone.Middle coarse sand particles are classified with deceleration and deflection of the air flow and discharge from medium sand outlet.Air will carry fine product material into fine classification area.The grading plates with arc-shaped guide plate forming dual effect of centrifugal settling and gravity settling.Fine sand product will be discharged at find sand outlet.Fine powder is entered to powder classification zone.Coarse material(fine sand)is separated under rotating action of the cage rotor.Fine sand separated at arc guide plate and falls into sand collection cone.The powder containing air flow enter cyclone for gas-solid separation.Find powder is discharged from the powder port;clean air is used for recycling.

Sand composite air separator has numerous advantages compare to conventional air separator:
1.Advance classification concept.It breakthrough the conventional water wash principle and adopted dual classification concept 1.centrifugal 2.Gravity.Materials are in the classification chamber,under swirl and tangential shear,created efficient classifications properties,and intensity.Powder selection material passes through clear grading interfaces.Classifications criteria is stable,and separation profile is highly accurate.
2.Operational friendly:Separator applied stepless speed frequency converter,convenient for product profile tuning,sensitive and reliable,wide adjustment limit.
3.Enhanced design in separator zone,large separation zone,improved separation efficiency.
4.New design of cyclone outlet with snail edge,adding air guide plate,improvise cyclone design structure,low air resistances,improved cyclone gas solid separation efficiency.
5.Equipment internal structure design has included multiple anti dew point devices.Thus,prevent dew point formation.

Features

1.The principle of separation is advanced:the product has a variety of classification systems,and the aerodynamic analysis method is used to optimize the material flow field,which allows the equipment operate at low air resistance,the separation efficiency is high and the significant energy saving.It is far advance compared to the traditional production process washed sand and gravel sorting.
2.The V shaped scatter grading area has the advantages of simple structure,less material consumption,electricity free operation.
scatter device,low pressure loss,stable operation and low power consumption.3.High separation accuracy.in the powder stripping machine,the"vortex rectifier",which is patented design,is adopted.The air flow in the rectifier only rises and does not rotate with respect to the rotor,and the material is cleaned repeatedly in the separation section,thus it achieve excellent classification results.
4.Simple operation.Cage rotor operated by stepless speed frequency converter.The range of adjustment is wide.The adjustment is convenient,sensitive and reliable
5.High classification efficiency.In the"V"type scattered powder selection area,set up multilayer break and grading plate are set up to repeatedly break up and blow off,so that there is almost no fine powder among the discharged coarse powder.In the settlement classification zone,the powder discharge port has air flow to make sure that the fine powder in the material is once again blown away,and the fine powder content in the material is greatly reduced.The baffle plate is added to Cage shaped rotor classification zone,thus making the grading more accurate and effective.
6.The wear resistant parts have minimum maintenance and long service life.The wearing parts of the main parts of the powder removing machine are made of imported wear-resistant steel plates,which effectively improves the service life.The whole machine is adjusted by dynamic balance,and it runs smoothly in the full speed range.
7.The main shaft seal adopts new design scheme,which effectively solves two important problems of bearing ash entry and lubrication oil leakage,and effectively prolongs the service life of the bearing.
8.in the design of the powder removal machine,the principle of mechanical vibration damping is adopted to make the vibration frequency of the separator machine not to form an integral relationship with the natural frequency of the separator machine and the resonance problem of the separator is solved in the long run.
9.Double interlocking air valves are adopted in sand pipes,middle fine sand pipes and fine sand pipes,which greatly reduces the leakage rate of the system and overcomes the defects of generating a large amount of dust during the operation the powder removing machine.
10.The system adopts double interlocking air valve and internal circulation air,effectively reducing the air leakage of the system and the dust pollution during operation.
