WAMSKIRT® System Eliminates Confined Space Entry

Location: Paraburdoo, Western Australia

Material Handled: Iron Ore

Handling System: Conveyor

Handling Rate: 4000 Tonnes Per Hour (TPH)

Challenge

An iron ore mine in the Pilbara had a solid wall skirting system installed on conveyors in the screen house which created the following challenges:

  • 32kg hard-to-handle liners and a basic sealing arrangement which was difficult to adjust
  • Confined space permits needed for maintenance
  • Skirting maintenance and adjustments were not carried out regularly as a result of the difficulty of working around above screen maintenance causing significant belt wear and spillage
  • Manual handling risks were high as the only method to replace liners was to crawl along the conveyor belt while dragging the 32kg liner.

Solution

WEARX designed and installed the WAMSKIRT® system - an externally maintainable skirting system. This eliminated confined space requirements for mine personnel and removed the need to interfere with the screen maintenance above.

The WAMSKIRT® system incorporates a removable module which allows every second liner to be removed leaving sufficient space to carry out maintenance on the remaining fixed liners.

  • All maintainable components on the system weigh less than 20kg for ease of handling.
  • A double urethane seal arrangement ensures all dust is captured.
  • The lower liner is designed to help push material away from the skirt wall to reduce spillage and eliminate any reliance on the dust seal for retention of material.
