The shaftless screw conveyor eliminates the need and allows a relatively high filling rate, thereby reducing the speed, increasing the conveying efficiency, and reducing wear. If there is no shaft, no intermediate bearing or end bearing is required. The groove liner is a spiral replaceable bearing surface. A machined bearing without shaft is located in the gear reducer.
This allows direct connection and optimizes the flexibility of layout design. In shaftless designs, the common solution is that end-to-end and side connections cannot be achieved on a screw conveyor with a shaft. The vertical shaftless conveyor can provide a single device with a relatively large length of 50 feet, and the elevation gain of the system exceeds 100 feet.
The resulting spiral is more resistant to fatigue, crack formation and growth. They are cold-formed into a spiral shape by our modern "accurately captured CNC winding skills", which can form diameter and pitch at the same time, and have many other advantages.
It is quite effective in conveying a lot of bulk materials. The zero gap between the groove and the spiral can achieve better performance, thereby increasing the conveying efficiency and cleaning up many common flow problems of axial flow screw conveyors.
Higher trough load allows lower operating speed. By designing equipment with fewer parts required, investment costs and overall maintenance costs can be reduced. The KWS screw conveyor is designed to provide greater flexibility and efficiency in the factory layout, providing end-to-end, side entry/exit and vertical configuration.
The screw conveyor can effectively transport dry, semi-fluid or viscous bulk materials. The shaftless design cleans up the need for intermediate shaft bearings, thereby providing a non-clogging conveying surface.
