Sludge shaftless screw conveyor is a type of conveyor system that is designed to move sludge or other viscous materials without the use of a central shaft. Instead of a shaft, the conveyor consists of a helical screw that rotates within a trough. The screw is typically made of stainless steel or other corrosion-resistant materials, and it is designed to move the sludge along the length of the trough with minimal resistance.If you're looking for an efficient and reliable way to move sludge or other sticky materials, a shaftless screw conveyor could be a good choice.
Sludge is a material with relatively large water content and a lot of mixed substances. Ordinary screw conveyors are good for conveying granular and powdery materials. The conveying sludge will block up and affect the normal operation of the equipment; but shaftless screw conveying The machine adopts a special design without central axis, its anti-winding property, viscosity is better, and the torque is large, up to 4000N/M, to ensure smooth sludge transportation without clogging.
The sludge contains a lot of water. The shaftless Screw conveyor adopts fully enclosed conveying and easy-to-clean spiral surface to ensure that the sludge will not be splashed and leaked during the conveying process, thereby protecting the working environment and hygiene. It is contaminated and does not leak, which reduces the cost of manual cleaning in the later stage.

The water content of the sludge is relatively high, which has certain requirements for the transportation output. Our Dahan produces a complete range of shaftless screw conveyor models, including WLS200, WLS250, WLS300, WLS350, WLS400, WLS500, etc., and can also be customized to meet customer material transportation requirements to the greatest extent; shaftless screw conveyor It can be opened for feeding, and the sludge can be conveyed horizontally and inclinedly. The conveying length of a single machine can reach 60~70m. During the conveying process, the materials can also be stirred, mixed, heated and cooled. Multi-stage series installation can realize ultra-long-distance sludge conveying.
The above is my introduction to the use of shaft screw conveyors for sludge. The shaftless screw conveyor produced by Dahan has great advantages in conveying materials with high water content, strong viscosity and easy winding. If you want to know more For more information about shaftless screw conveyors, you can contact Dahan manufacturer at any time, and we will have specialized personnel to explain to you.
When slurry is dewatered through a belt filter press, decanter centrifuge or filter press, it may be necessary to use lime and transport it to storage areas (silos, zones, silos, etc.).
