Shaftless Sludge Screw Conveyor for Dewatered Sludge Transfer in Wastewater Treatment Plants
Brief Description
The Shaftless Sludge Screw Conveyor is designed to transfer dewatered sludge and sludge cake between treatment units, discharge outlets, and collection containers. Its shaftless spiral structure provides conveying space for cohesive materials and helps reduce the wrapping of fibrous substances around a central shaft. The conveyor can be integrated with screw press dewatering machines and other sludge handling equipment.
Product Overview
The Shaftless Sludge Screw Conveyor is used in sludge handling systems where dewatered sludge must be transferred from one process location to another.
After mechanical dewatering, sludge cake may need to be conveyed to a collection bin, storage area, or subsequent handling system. The shaftless conveyor provides a mechanical transport solution that can be configured according to sludge characteristics and the plant layout.
The conveyor can be supplied with a suitable trough, cover, drive system, and discharge arrangement. Its actual conveying performance depends on sludge moisture content, consistency, bulk density, conveyor geometry, and operating conditions.
Working Principle
Dewatered sludge enters the conveyor through the inlet or receiving hopper. The motor and gearbox rotate the shaftless spiral, pushing the sludge along the conveying channel toward the discharge outlet.
The conveyor transfers the sludge to a collection or downstream handling point. The spiral diameter, rotational speed, trough dimensions, and installation angle are selected according to the required conveying capacity and sludge properties.
