Widely regarded as one of the most technically advanced conveyor systems in the world, due to its energy efficiency and unique component design. The Henderson overland system is located approximately 80 kilometres west of Denver, Colorado USA.

The project was completed in 1999 to replace the existing rail infrastructure which transported molybdenum from the mine using a 3 flight conveyor system.

The 3 flights consisted of the following conveyors,

  • PC1 –  a 1.2km high lift conveyor which transports ore from the underground crushing station to the end of the existing rail tunnel,
  • PC2 – 17km overland utilising existing rail tunnels from the east side of the continental divide to the mill located on the west side, and
  • PC3 – 6.3Km overland from the tunnel portal to the mill through a series of 9 horizontal, 9 vertical curves and inclines of up to 15 degrees

Key Statistics

  • Belt Width: 1200mm
  • Capacity: 2,270 Tph
  • Speed: 4.5 – 6.1 m/s

Lorbrand idlers were selected for exclusive use on the project after extensive testing which, proved the high manufacturing standards and low rolling resistance of our conveyor idlers.

The significance of the Henderson project and its unique design, sees it taught at several leading mining school & institutions across the globe, including Western Australia’s School of Mines.
