Low Energy Consumpion

Energy Efficient and Continuous Transport of Solid Bulk Materials. The TubeFeeder® is designed to
provide continuous, high-volume reclamation of bulk materials. The system ls energy efficient consuming
as little as 25% of the power needed for traditional exposed screw reclaimers. lt also provides for gentle
handling of the materials and can be installed in flat bottomed bunkers and silos with large spans and
diameters, in addition to open air stockpiles. The TubeFeeder® is well suited for processes that require
a high level of accuracy; it offers a superior solution for industries that place exacting demands on
efficiency and performance of their materials handling processes.

The diagram shows the potential for
reducing the energy consumption when
using a TubeFeeder® compared to a
rotating screw under the same working
conditions.

Rotating screw TubeFeeder

The TubeFeeder® is also characterized by high discharge accuracy.
In short, it allows for better process control. The TubeFeeder® consists of a driven tube with evenly
spaced openings. In the pipe, the screw conveyor is mounted, which is shielded by the pipe.
The bulk material passes through openings in the tube as the tube is rotating and transport the material
to the end of the tube. By using the tube, the TubeFeeder® has clear advantages over conventional
systems. Since the tube "floats" practically in the material, there are also no loads from the bulk density
of the product, especially to no deflection. This allows larger plant dimensions. Moreover, this process
does not generate any shear stress - the energy consumption is extremely low.
