Flexible screw conveyor

‹‹ ››

Mechanical flexible screw to avoid the obstacles

The flexible screw is used to carry powders, granules or pellets. The compatibility of materials conveyed must be validated by PALAMATIC PROCESS. By their mode of operation and design, these screws impose specific implementation recommendations. The advantages of the flexible screw are its compact size and its flexibility of installation.

Advantages of flexible screw conveyors

  • Tube manufactured in semi-rigid polyamid with excellent abrasion resistance, vibration absorption and certified for food products.
  • Flexibility of the conveyor which goes around above, below or laterally any machine already in place.
  • Protection Protection against environmental moisture: ideal for dehydrated or dried products. 
  • Easy maintenance to remove residual material from the conveyor by rotating the device in the other direction.
