Underground Mine Crusher Detailed Design & Commissioning

Northern Ontario

The client’s existing open jaw crusher rapidly developed defects that would limit its lifespan. As a result the client’s minesite had to replace the crusher in a short timeframe. The existing crusher was replaced with a modern, more compact open jaw crusher which required extensive modification to the steel work, material handling, electrical, and automation infrastructure to support it.
Shield was the only engineering consultant to accept the tight timeline and leveraged its technical abilities to rapidly re-design the material handling, structural steel, electrical and automation systems to provide its client with a functional replacement solution. Shield provided extensive support through the construction process, working closely with contractors and the mine owner to facilitate a condensed construction timeline, minimizing the mine’s downtime.

SERVICES RENDERED:

  • Shield provided a host of services to meet the compressed timeline. The crusher area was laser scanned and the the replacement crusher, structural steel, material handling equipment interfacing with the crusher were parametrically designed in 3D. Leveraging Shield’s advanced 3D design abilities allowed project stakeholders to clearly understand how the final deliverable would work. Moreover, designing in 3D allowed the project stakeholders to consider and plan maintenance, ergonomics, operational, and optimize the design for construction, a challenging task given the compressed timeline.
  • Shield’s electrical and automation team adapted an innovative approach to electrical and instrumentation aspect of the job by skillfully integrating the new crusher system with the site’s existing electrical/instrumentation infrastructure. Eliminating the need to replace existing site infrastructure by re-using and modifying existing systems permitted the compressed timeline as well as saved cost in purchasing new systems and equipment.
  • Shield provided fabrication drawings and NC data which were provided to fabrication shops, eliminating the need for the fabrication shop to re-draw fabrication drawings to build the provided designs, further saving time.
  • Shield also provided on-site inspection services ensure that the existing steel, concrete, crane infrastructure were in an acceptable state of repair for construction and continued service with the replacement crusher. These services were provided throughout the course of the project.
  • During the construction phase, Shield provided anchor bolt layout services which were extracted directly from the 3D model. The anchor bolt layout activity accelerated the project timeline as the contractor was able to perform site preparation activities while the anchor bolts locations were set by the Shield team, allowing further compression of the construction timeline.
  • Shield’s electrical/automation team provided on-site support during construction working with the mine owner and contractor assisting with the wiring of electrical systems ensuring smooth commissioning. Shield also assisted with interfacing the crusher with existing site logic systems and provided technical support to ensure that the replacement crusher and its associated systems were correctly interface ensuring safe and dependable operation.
