Screw the working principle and application characteristics



 Screw conveyor rotating helical blade for screw conveyor passage of the material transported, so that the material does not rotate together with the screw conveyor blades is

the material force of its own weight and the frictional resistance of the material conveyor chassis. Rotating shaft screw conveyor spiral welded blades, blade face delivery of

materials based on a solid surface different type, belt type face, leaves and other types of face. Screw conveyor screw axis in the direction of movement of the material with

the thrust bearing to the terminal with the material to spiral axial reaction force, the captain longer, should be added to intermediate hanger bearings.

First, the working principle of screw conveyor

    Simple structure, small cross-sectional size, good sealing, reliable, low cost, ease of loading and unloading the middle, reversible transport direction, while the opposite

can also be transported in both directions. But also on the material during transport stirring, mixing, heating and cooling operations. By loading gate adjustable material flow.

But not transport perishable, viscous, easy caking and bulk materials. Easily broken during transportation of materials, screw and trough easy to wear. Larger power units. Use

and to maintain the tightness of the spiral chute with proper clearance between the trough.Telescopic belt conveyor

Second, the application of screw conveyor

    Transportation of materials from the perspective of the direction of displacement divided into horizontal screw conveyor screw conveyor screw conveyor and vertical two

types, mainly used for all kinds of powder, granular and small block, such as the level of transport loose materials and vertical lift, the aircraft is suitable for transporting

perishable, viscous, easy caking or high temperature, afraid of pressure, there is greater corrosive special materials. Screw conveyor is metallurgy, building materials,

chemical industry, food processing and other sectors and machinery widely used as a continuous conveyor.

 Third, the characteristics of screw conveyor

    Vertical screw conveyor is suitable for short distance vertical transportation. Flexible screw conveyor screw by a flexible shaft and blade composed of synthetic rubber, Airport conveyor

easy to bend, or process according to the site requirements of any arrangement for space transportation. There are pull-type screw conveyor blade and pull the entire loss, now

pull any thickness can be made with the specifications of size, should not be made whole pull nonstandard helix. Easy installation and maintenance, commonly known as auger screw

conveyor is minerals, feed, grain, construction industry uses a broader transportation equipment, transportation of materials from the perspective of the direction of

displacement divided into horizontal screw conveyor and screw conveyor Two types of vertical screw conveyor, mainly used for all kinds of powder, granular and small block, such

as the level of loose material transport and vertical lifting.
