Situation

The dust collection and disposal system at the Tom Price ore processing plant screenhouse has been operating since the
1960’s and was determined to be beyond repair.

The system was non-operational for a number of years and
partially deconstructed. A study was conducted to determine the current condition of the extraction equipment which concluded the ducting, fans and dust collector required a complete replacement.

Solution

Aerison was engaged as the primary contractor to deliver the engineering and design, civil, structural, mechanical, electrical, fabrication, installation, and commissioning works.


Scope:

  • Replacement of the existing dust collection and disposal system at the screen house
  • Detailed design of a new dust collection and disposal system including a clean and a dirty air duct system, access platforms and duct support structures,
  • Deconstruction and offsite disposal of existing dust collection system including fans, existing ducting, hoods,
    dust collectors, structures, electrical infrastructure & dust discharge system

Project highlights:

  • Aerison’s construction methodology provided a modularised fabrication solution including full assembly of structural, mechanical, electrical and instrumentation with heavy-lift placement on-site.
  • A four-cell baghouse with design capacity of 164,077 m³/hr,
  • Heavy-lift placement on-site.
  • Two centrifugal extraction fans operating in parallel.

Outcome

  • Site-based construction time was less than half the duration expected through conventional methods.
  • Dust mitigation in the vicinity was significantly improved, reducing respiratory and optometry risks
  • Facility performance meets environment requirements
  • Improved production efficiency by recovering fines product and reducing material loss
