Why Are Shaftless Conveyor Systems Becoming More Popular?

Traditionally, shafted conveyors were used to move industrial materials around in the mines and other businesses. Now, shaftless conveyors are gaining in popularity because they offer long term cost savings.

The Old Way vs The New Way

  • Shafted screw conveyors
  • Thinner spirals surround a shaft
  • Maintenance requires you to remove motor and gear box
  • More energy is required
  • Shaftless screw conveyors
  • Thicker spirals that last longer
  • Maintenance time is cut by half – fully portable
  • Power saving
