Shaftless Screw  Conveyors

The Sydex shaftless screw conveyors have been developed and design for transferring materials, such as dry sludge, efficiently with minimal maintenance and maximum reliability. It rotates inside a trough with a maximum inclination of 30°.

​

In order to reduce maintenance costs, the gearbox is directly connected to the shaftless spiral above the discharge point. Therefore, the only moving part in contact with the product is the screw itself, eliminating any requirements for expensive bearing or mechanical seal arrangements.

The design and the selection of materials can easily be adapted to the properties of the product to be conveyed.
