SPIROLINE ® conveyors feature a U-trough with a low RPM shaftless spiral screw riding on a special low friction long life trough liner. Material handling can place a lot of pressure on equipment, as many of the industries SPIRAC serves feature harmful, possibly corrosive substances.
SSC Shaftless Spiral (Screw) Conveyors offer large volume capacity and the possibility of handling particularly difficult materials. They are designed for handling of urban solid waste, screenings and floating matter, de-watered, thickened, or conditioned sludge, packaged food, creams or pastes, as well as waste from meat, fish, fruit and vegetable processing.

Apr 26, 2008· Hi, I have a pretty good idea how to calculate the required horsepower to obtain a certain capacity with an ordinary screw conveyor as a function of material type, screw dimensions, etc. I was wondering how do these same calculations differ for shaftless screw conveyors? Anyone can give me some pointers? Thanks a lot, Dimitri
Calculate Horsepower For Inclined Screw Conveyors - Blogger. 2008-01-09· Calculate Horsepower For Inclined Screw Conveyors Screw conveyors can be used to convey bulk materials at an inclined angle, but several areas of design should be examined first Because of the incline of the screw, several conveying problems begin to occur
The trough liner is the spiral's replaceable bearing surface. The only machined bearings in a shaftless are in the gear reducer. This allows for direct connections and optimizes layout design flexibility. End-to-end and side connections not possible on shafted screw conveyors are common solutions available in the shaftless design.
