What is the difference between shaftless and shafted screw conveyors

What is the difference between shaftless screw conveyor and shaft screw conveyor?

1. The conveying materials:

Shaftless screw conveyor is suitable for conveying materials: sludge, domestic garbage, grille slag, etc. have viscous, entangled materials and bulk materials. It is precisely because the design of the shaftless screw conveyor without a central axis has great impact on these materials The advantages.

The shaft screw conveyor is suitable for conveying materials: powder, small particle materials, etc., if you convey viscous materials such as sludge, it will stick to the inner pipe shaft and blades, and the conveying block materials are easy to jam.

2. The conveying form:

Shaftless screw conveyor is suitable for: horizontal conveying, the maximum inclination angle should not exceed 20°, according to the actual usage.

The shaft screw conveyor is suitable for: horizontal conveying, inclined conveying, and vertical conveying.

3. Features of shaft screw conveyor:

1). Large carrying capacity, safety and reliability.

2). Strong adaptability, convenient installation and maintenance, and long life.

3). The whole machine is small in size and high in speed, ensuring fast and uniform delivery.

4). Good airtightness, the shell is made of seamless steel pipes, and the ends are connected by flanges to form a whole, with good rigidity.

High-efficiency conveying: small diameter, high-speed, variable-pitch spiral design to ensure smooth, fast and uniform feeding of products during work.

Arbitrary arrangement: The outer shell of the conveyor is made of high-quality seamless steel pipes connected by flanges as a whole, and the overall rigidity is good. It can be continuously conveyed whether it is horizontal or large inclination, and it can be directly connected and fixed with the supporting equipment without foundation. The foundation makes full use of space, and it is very convenient to move and disassemble.

Reliable seal: The lubrication seal is reliable without leakage, no waste of materials, and a good working environment is created.
