Trash interception, sand removal, and conveying equipment

[Overview]

As the name suggests, a shaftless screw conveyor is a unique structure without a central axis, which is the fundamental difference between it and traditional screw conveyors. Its working principle is to push materials through an integral steel spiral component to achieve conveying of the mother. Because this component has a certain degree of flexibility, its resistance to winding is enhanced. Therefore, shaftless screw conveyors have particularly obvious advantages when it is easy to wrap materials.

Application of shaftless screw conveyor

The SSD series shaftless screw conveyor [1] is essential for the transportation of medium and fine grids in sewage treatment plants. The slag and filter cake of the cleaning machine with a net distance of about 50mm cannot be separated from the shaftless screw conveyor. This type of screw conveyor has excellent environmental performance, with a fully enclosed design and an easy to clean spiral surface, achieving the possibility of conveying materials without pollution or leakage. Due to its maximum torque of 4000N/m, this type of conveyor is less prone to material blockage, and the discharge port is not blocked. It can operate at lower speeds to save energy. The conveying capacity is large, which is 1.5 times that of traditional axial screw conveyors with the same diameter. Long conveying distance, with a single machine conveying length of up to 60 meters. If requested by the customer, a multi-stage series design can be used to achieve ultra long distance transmission. The mobile shaftless screw conveyor developed by our company is capable of mobile operation and can be used for multiple purposes. The discharge port can be located at the end or below, and can also work in high temperature environments. It has a generous appearance, saves space, is easy to operate, and is reasonably priced.

Advantages of shaftless screw conveyor

1. Has environmental characteristics. Due to the fully enclosed design of this type of conveyor, it is difficult for materials to be contaminated during transportation.

2. Compared to the Youzhou screw conveyor, its conveying capacity is 1.5 times that of the same diameter axial screw conveyor.

3. Blockages rarely occur during the work process.

4. The longest conveying distance can reach 60-70m.

5. Elegant appearance, space saving, easy to operate, and reasonable price.

Application scope of shaftless screw conveyor

This type of screw conveyor is widely used in industries such as smelting, agricultural production, chemistry, and building materials. With an inclination angle of β<20 °, it can transport powdery, granular, or small pieces of material that have low viscosity, are not easily deteriorated, and are not clumped.
