Screw conveyors.

They are volumetric conveyors used for transporting granular solids. Due to their design and construction, they are robust, highly reliable units with low maintenance requirements. Manufactured in a wide range of diameters—with standard, progressive or conical pitch executions, twin-screw assemblies, feed hoppers and fill-level control, etc.—these conveyors allow broad adaptation to the requirements of each project.
