Shaftless Conveyors
Shaftless Screw Conveyors are a specialized alternative to the standard Shafted Screw Conveyor. Because the Shaftless conveyor does not have a center pipe they are easily identified and are uniquely capable of transporting more difficult materials that normally could not be conveyed by a traditional shafted screw conveyor. These difficult materials usually are high in moisture, sticky and or stringy which cause the materials to build up on the center pipe of a screw or on the flights. The Shaftless Screw Conveyor rides completely on the wear resistant trough liner and in doing so a tail bearing and tail seal are not required, thus eliminating normal maintenance items associated with standard screw conveyors.
Shaftless Conveyors can be found in many industries due to these unique capabilities such as:
  • Waste water treatment plants
  • Rendering and other meat processing
  • Fruit and vegetable processing
  • Pulp and paper plants
  • Chemical manufactures
  • Sugar Mill plants
Shaftless Screw Conveyors as do standard screw conveyors can be manufactured in a variety of materials such as Mild Steel, Stainless Steel, and other alloys. The spiral of a shaftless conveyor is considerably thicker than a standard flight, which is required in order to maintain the spiral rigidity. They are available in single spiral as well as double spiral. Normally the outer spiral is 1" thick and the inner spiral is 3/4" thick depending on the size of the conveyor. Shaftless Conveyors are available in 9" to 24" diameter. Our experienced Sales and Engineering staff are waiting and prepared to help you with all your material handling equipment needs.
