Tracked mobile jaw crusher in operation on a Pilbara campaign
Equipment

Fleet register.

Categories that run across every campaign and contract. Plant is configured per project, sized to your material and output spec. Specific units confirmed in scoping.

/ Categories

7 categories across the circuit.

Primary through tertiary crushing, screening, scalping, and material handling. Configured per project.

/ Primary

Primary jaw crushers

Capacity: Up to 600+ TPH typical

Tracked mobile jaw crushers configured for primary reduction across a range of feed sizes. Typical throughput depends on feed material and closed-side setting. Used as the first stage in a multi-stage crushing circuit or as standalone primary on smaller campaigns.

/ Typical materials
  • Blast rock
  • Limestone
  • Basalt
  • Granite
  • Hard rock
  • DSO iron ore
/ When to specify
  • Large feed material requires primary reduction (>500mm)
  • Starting a multi-stage crushing circuit
  • Standalone primary crushing for direct-load or rough stockpile
/ Primary

Scalpers

Capacity: Up to 600+ TPH typical

Heavy-duty scalpers used as the first separation stage, taking ROM material and pre-sorting before the primary crusher. Reduces unnecessary load on the primary and removes oversize, fines, or contaminants.

/ Typical materials
  • ROM material
  • Quarry feed
  • Recycled materials
  • Demo waste
/ When to specify
  • Pre-sorting ROM material
  • Removing fines or oversize before primary crushing
  • Recycled materials separation
/ Secondary

Secondary cone crushers

Capacity: Up to 400+ TPH typical

Tracked mobile cone crushers used in the second stage of a circuit, taking primary output and reducing to specification fractions. Cone crushers produce more cubical product than impactors, which matters for aggregate spec compliance.

/ Typical materials
  • Limestone
  • Basalt
  • Granite
  • Hard rock
  • DSO iron ore
/ When to specify
  • Spec-compliant aggregate sizing required
  • Cubical product shape needed
  • Hard, abrasive materials
/ Tertiary

Tertiary cone & impact crushers

Capacity: Up to 250+ TPH typical

Tertiary cone crushers or vertical shaft impactors used as the final reduction stage to produce manufactured sand and fine aggregate fractions. Specified when finer fractions are required and when output shape matters for downstream use.

/ Typical materials
  • Aggregate fines
  • Manufactured sand
  • Crushed rock fines
/ When to specify
  • Manufactured sand or fine aggregate spec
  • Tight gradation requirements
  • Final stage of a multi-stage circuit
/ Screening

Mobile inclined screens

Capacity: Up to 500+ TPH typical

Tracked mobile screens with single, double, or triple-deck configurations. Used alongside crushers in a circuit or standalone for stockpile classification and sizing. Deck setup is matched to the output spec during scoping.

/ Typical materials
  • All crushed and stockpiled materials
/ When to specify
  • Multi-fraction product separation
  • Standalone stockpile classification
  • Spec-critical aggregate sizing
/ Material handling

Stackers & radial conveyors

Capacity: Per circuit demand

Mobile stackers and radial conveyors used to build organised stockpiles, segregate fractions, and feed downstream equipment. Specified based on stockpile geometry, available footprint, and reach requirements.

/ Typical materials
  • All output fractions
/ When to specify
  • Building separated stockpiles by fraction
  • Stockpile feeding for direct-load operations
  • Tight site footprint with reach requirements
/ Support

Support plant

Front-end loaders and excavators for feeding circuits and stockpile management. Supplied on request as part of full-service campaigns where the client doesn't have suitable plant on site. Otherwise integrated with the client's existing fleet.

/ Typical materials
  • All operations
/ When to specify
  • Client doesn't have suitable feed plant on site
  • Remote campaigns needing self-contained crew + plant
  • Stockpile reclaim and material movement

/ Specific unit makes, models, and serials supplied on request to procurement teams. Email hello@rostrevorgroup.com.au.
