The difference between a shaftless screw conveyor and a shafted screw conveyor

Materials
1. The shaftless screw conveyor is mainly used for conveying sludge, domestic garbage, grid slag and other viscous, entangled and lumpy materials. It is precisely because the design of the shaftless screw conveyor without a central shaft has great advantages for these materials.
2. The shafted screw conveyor is suitable for conveying materials such as powder and small granular materials. If viscous materials such as sludge are conveyed, they will stick to the inner tube shaft and blades, and the conveyed blocky materials are easy to get stuck.

Delivery form
1. The shaftless screw conveyor is suitable for: horizontal conveying, the maximum inclination angle should not exceed 20°, according to the actual use situation.
2. The shaft screw conveyor is suitable for: horizontal conveying, inclined conveying, vertical conveying, combined with industrial and mining and conveying materials, let professional manufacturers select and design for you.

The difference between tubular screw conveyor and U-shaped screw conveyor
1. The difference of conveying materials
Tubular screw conveyors are suitable for various industries, and are suitable for horizontal or inclined conveying of powdery, granular and small lump materials, such as coal, ash, slag, cement, grain, etc. It is not suitable for conveying perishable, viscous, easily Agglomerated materials, because these materials will stick to the screw during conveying, and rotate with it without moving forward or form a material plug at the suspension bearing, so that the screw machine cannot work normally.

U-shaped screw conveyor is suitable for conveying powdery, granular and small block materials, such as cement, fly ash, grain, chemical fertilizer, mineral powder, sand, soda ash, etc.

Tubular screw conveyors are also capable of conveying the same materials that U-shaped screw conveyors can, so tubular screw conveyors may be more advantageous.

2.The difference in conveying distance
U-shaped screw conveyor is a kind of screw conveyor, which is suitable for small-scale operations, stable transportation, and can play a good role in the case of limited transportation sites.

Tubular screw conveyor has the advantages of multi-connection, so it can transport materials over a long distance. The conveying length of its single machine can reach 60 meters, which can fully meet the needs of customers.
