The U-shaped spiral conveyor mainly consists of a U-shaped trough body, spiral

blades, driving device, support, feed port and discharge port, is suitable for conveying

powdery and granular materials, such as grain, cement, fertilizer, plastic pellets,

mineral powder, etc. Due to its compact structure small footprint, good sealing, high

conveying efficiency and stable operation, it is widely used in chemical, building

materials, food, metallurgy and other industries. Compared with types of spiral

conveyors, the U-shaped spiral conveyor is more suitable for conveying materials that

are prone to blockage, and its trough body can be designed and customized to needs

to adapt to different conveying requirements.




Screw conveyor composition structure:

1. Driving device: adopt cycloidal gear reducer or shaft-mounted hard tooth surface

gear reducer, and driving device should be designed at the discharge port end as

much as possible, so that the spiral body is in a tensile state during operation.

2. The head is equipped with a thrust bearing, which can withstand the axial force

generated during the conveying of materials.

3. Spiral blade: generally made of stainless steel or carbon steel If the service life is

considered, it is recommended to use spiral conveyor blades made of high-strength

wear-resistant steel.

4. Machine shell: it is a "U"-shaped slot type, with a rain-proof machine cover on the

upper part, and the material can be stainless steel or carbon steel or glass fiber

reinforced plastic.

5. Liner of the slot body: made of high-strength engineering plastic high molecular

polyethylene, with weak adsorption, no sticking, wear resistance, and corrosion.

6. Feed and discharge ports: there are two types, square and round, and the form of

the feed and discharge ports is generally determined by the user.

The spiral blade is welded on the rotating shaft of the U-shaped spiral conveyor, and

the spiral blade will rotate to produce forward power when working, forcing the

material to move forward to complete the conveying. In this process, the reason why

the material does not rotate with the blade is that one is the gravity of material itself,

and the other is the friction resistance of the inner shell of the equipment on the material.




U-shaped spiral conveyor is suitable for small-scale operations, with stable conveying

and can perform well under limited conveying site conditions. It has good performance,

which is extremely advantageous for occasions with large dust and environmental

requirements, and can avoid the generation of dust during the conveying process.

1. Thickened spiral the inlet: The thickness is about 6~8mm, and it can also be

thickened according to the wear resistance of the material.

2. Multiple materials: The shell material can be carbon steel/stainless steel, and the

conveying materials are extensive.

3. No blockage: The discharge port is equipped with a cleaning to ensure that the

material does not block, and the conveying is more reliable.

4. No dust: The hanging bearings use sliding bearings with dust-proof sealing devices,

have good sealing effects.

5. Flexible layout: Continuous conveying can be achieved horizontally/large inclination,

which is suitable for more different application scenarios.

6. High-eff conveying: The design of the spiral body with small diameter, high speed,

and variable spiral ensures that the product is smoothly and quickly fed evenly during

the working process.

7. Diversified connection: The inlet and outlet ports can adopt universal ball, cloth bag,

flange, and other connection methods.
