Spiral Screws

Shaft less spiral screws are primarily used for the conveying of viscous products. Due to "missing"
a central shaft products can be conveyed with large particles (pollution . The spiral has no bearings but is running on plastic wear shells or on steel wear strip. As a result, large conveying distances (up to 40 meters in length) are possible. Shaft less screw conveyors reduce maintenance costs , because they are able to work with a considerably higher filling levels than a conventional screw coveyor.
