Basalt & Hard Rock.
Basalt, granite, and hard rock reduction. Heavy-duty multi-stage circuits producing high-strength aggregate to civil and infrastructure spec.
Basalt, granite, and other hard-rock quarry materials processed for civil and infrastructure use. High-strength aggregate for sealing, road base, asphalt manufacture, and structural concrete feedstock.
Hard rock requires heavy-duty plant — primary jaw with strong throat opening, secondary cone for cubical product shape, optional tertiary stage for fine fractions. Wear parts and maintenance schedules are calibrated for abrasive material.
Victorian quarry operators are the largest basalt segment. Queensland has comparable hard-rock projects. Plant deployable to other states for civil infrastructure programmes.
/ Confirmed per client spec at scoping
- Primary crushed basalt (50-150mm)
- Road base spec (20-40mm)
- Sealing aggregate (7-14mm, 10-20mm)
- Fines for asphalt manufacture
- Primary jaw crushersHeavy-duty mobile jaw crushers for primary reduction of blast rock and quarried material.
- Secondary cone crushersMobile cone crushers for secondary reduction and shaped product output.
- Tertiary cone & impact crushersFinal-stage reduction to fine fractions with controlled output shape.
- Mobile inclined screensMulti-deck inclined screens for precision classification.
Best run as: Contract Crushing.
Continuous crushing supply for clients running sustained production programmes. Modern fleet, structured maintenance, dedicated crews. Built for partnerships measured in years, not weeks.
Basalt & Hard Rock questions.
Can Rostrevor handle the wear from abrasive hard rock?
Yes. Wear part schedules and maintenance windows are calibrated for the specific material. Structured preventative maintenance is built into every contract and campaign.
What basalt fractions do you produce?
Common civil fractions (50-150mm primary down through sealing aggregate and asphalt fines) plus client-specific spec sheets. Output is confirmed during scoping.
- DSO Iron OreDirect shipping ore. Specialised lump and fines crushing for mining clients with field-resilient plant and FIFO-ready crews.
- LimestoneLimestone reduction for quarry, civil, and cement applications. Single-stage primary through multi-stage circuits producing spec-compliant aggregate.
- Recycled Concrete & C&D WasteRecycled concrete, brick, asphalt, and mixed demolition waste reduction. Continuous-programme experience with operators measured in years, not months.
- Road Base & Sub-BaseRoad base and sub-base production. Spec-compliant gradation from primary blast rock through to finished civil aggregate.
