Powder Pellet Bulk Material Dia 400mm Tubular Screw Conveyor
Introduction of Tubular Screw Conveyor
Tubular 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.
Composition of Tubular Screw Conveyor
Tubular Screw Conveyor is usually composed of screw conveyor body, in and out device and driving device.

Principle of Tubular 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.
Advantages of Tubular Screw Conveyor
(1) Large bearing capacity, safe and reliable.
(2) It has strong adaptability, convenient installation and maintenance, and long service life.
(3) The whole machine has small volume and high speed, which ensures fast and uniform transportation.
(4) The discharging end is equipped with cleaning device, the whole machine has low noise and strong adaptability, and the position of inlet and outlet is flexible.
(5) The shell is made of seamless steel pipe, and the ends are connected with each other into a whole body with good rigidity.
Compared with other conveying equipment, screw conveyor has the advantages of small cross-section, good sealing performance, stable and reliable operation, multi-point loading and unloading, safe operation and easy maintenance.
Application scope of Tubular Screw Conveyor
Tubular 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 ℃.
Tubular 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.
