273mm Outer Diameter Carbon Steel Pipe Screw Conveyor
Introduction of Pipe Screw Conveyor
Pipe Screw Conveyor is a kind of conveyor which uses the rotating
spiral blade to move materials and carry out screw conveying. Screw
conveyor, commonly known as auger, is a kind of conveying equipment
widely used in mineral, feed, grain and oil, construction industry,
used to transport powder or solid particles and other chemical and
building materials products.
Advantages of Pipe Screw Conveyor
Pipe Screw Conveyor application features are: easy to multi-point
loading and unloading, can also complete the function of mixing and
mixing in the process of transportation; sensitive to overload,
easy to block, large energy consumption; crushing of coarse
materials, suitable for conveying fine coal. Its structural
features are: simple structure, easy maintenance, reliable work;
small cross-section coefficient, compact and flexible layout;
airtight transportation, less environmental pollution, can improve
the working conditions; serious wear and tear of machine parts, low
conveying capacity.

Principle of Pipe Screw Conveyor
When the screw shaft rotates, due to the gravity of the material
and the friction between the material and the tank wall, the
material can only move forward along the bottom of the conveyor
under the push of the blade. Therefore, the transportation of
materials in the conveyor is completely a sliding movement.
Application scope of Pipe Screw Conveyor
Pipe Screw Conveyor is widely used in various industrial sectors,
such as building materials, electric power, chemical industry,
metallurgy, aluminum and magnesium, coal and machinery; it is used
to transport powder, granular and small fast materials, such as
cement, coal powder, grain, fertilizer, ash, sand, etc., with
material temperature below 100 ℃.
Pipe Screw Conveyor is not suitable for the screw machine to
transport materials that are easy to deteriorate, sticky and
caking, because these materials will stick to the screw during
transportation, and then rotate without moving forward, or form a
material accumulation plug at the hanging bearing, which makes the
screw machine unable to work normally.
