The shaftless screw conveyor, compared to the traditional shafted screw conveyor, boasts the following outstanding advantages due to its adoption of a centerless design and the use of a flexible, all-steel spiral for material conveyance: excellent anti-tangling performance. The absence of a central shaft eliminates interference, providing unique superiority for conveying sheet-like or easily tangled materials.
Applicable Occasions:
The WLS series shaftless screw conveyors are designed for sludge removal in wastewater treatment plants, conveying debris from fine格栅 with a grid spacing of 50mm and filter press cake. They offer excellent environmental protection performance. Featuring a fully enclosed conveying system and easy-to-clean screw surface, they ensure hygienic conditions and prevent contamination and leakage of the conveyed materials. They have high torque and low energy consumption. Due to the shaftless design, material clogging is minimized, and the discharge outlet remains clear, allowing for operation at lower speeds with smooth transmission and reduced energy consumption. The torque can reach up to 4000N/m. They have a high conveying capacity, 1.5 times that of traditional shafted screw conveyors of the same diameter. The conveying distance can be extended up to 30 meters per unit. They can also be installed in a multi-stage series configuration for ultra-long distance conveying upon customer requirements. Our company's mobile shaftless screw conveyors are versatile, capable of operation at high temperatures using special linings. They are compact, space-saving, aesthetically pleasing, easy to operate, and economically durable.
Axleless Screw Conveyors Application: Custom-designed for conveying drilling mud sludge in non-dumping waste slurry treatment systems, kitchen waste/large-scale household waste, and sludge cake transportation, etc.
Structure Composition:
The shaftless screw conveyor is mainly composed of the drive unit, head assembly, housing, shaftless screw, trough liner, feed opening, discharge opening, cover (if required), and base.
1. Drive Unit: Utilizes a cycloidal pinwheel reducer or a shaft-mounted hobbed gear reducer. During design, it is recommended to place the drive unit as close to the discharge end as possible to keep the spiral in a tensioned state during operation.
2. Header Assembly: Equipped with thrust bearings capable of withstanding the axial force generated during the conveying of materials.
Shell: U-shaped or O-shaped shell with a rainproof cover on top, available in materials such as stainless steel, carbon steel, or fiberglass.
4. Axleless Spiral: Made of stainless steel or carbon steel.
5. Tank Lining Plates: Made of wear-resistant plastic, rubber, or cast stone plates, etc.
6. Inlet and outlet ports: Available in both square and round shapes. The type of inlet and outlet is usually determined by the customer.
