4 pcs. shaftless screw conveyor manufactured for removing rock waste in a biogas plant. The minor rock parts are removed from the process, and the shaftless tube conveyor transport them and dump it into a small container.
When using shaftless screw conveyors, the speed of the screw rotor has to be relatively low – typically below 30 RPM. If the transport requires a high volume flow in combination with a speed above 50 RPM, the shaftless screw conveyor is not a stable solution. In such case you shall use a conventional screw conveyor with an inner pipe.
BEMA has production capability to manufacture shaftless screw conveyors as well as conventional screw conveyors with an inner pipe. Our engineers and designers can assist you in selecting the most optimal solution for your application.

BEMA has developed efficient method for handling Hardox and other hardened steel types for manufacturing screw flights:
If you have abrasive materials to be transported these type of steel will increase the lifte time of the application.
BEMA can always assist you with advise when you evaluate which type of screw flight you want to use for your application – shaftless type or a conventional screw rotor with flight segments welded to an inner pipe.
