Quarry crushing
and aggregates

In the quarry, the rock dictates the costs. The harder and more abrasive it is, the more it tests your machines: wear, breakage, downtime. WEIL crushers are designed for these extreme conditions, from blasting to graded aggregate.

The quarry operator's challenge

In the quarry, cost comes from the rock

Before energy, before labour, it is the abrasiveness of the rock that determines the real cost of each tonne you produce. The harder and more abrasive the material, the more it wears the crushing tools: accelerated wear, breakage, downtime. On this demanding ground, the choice of machine is not decided on theoretical throughput, but on its ability to last.

1st cost item Wear from abrasiveness, ahead of energy
Hardness ↑ The harder the rock, the higher the wear costs climb
Downtime Every tool breakage stops the whole line
WEIL Mechanics designed for these conditions
Why WEIL in the quarry

The WEIL advantage on difficult rock

Four concrete points that make the difference to operating cost, where the rock is most demanding.

Long-life wear parts

Crushing tools and liners sized for abrasive rock. A maximised service life that spaces out replacements and reduces the cost per tonne.

Structural robustness

Reinforced frames, large-diameter spherical bearings and a massive design: the machine takes impacts and overloads without premature fatigue.

Accessible maintenance

Rapid tool changes, easy access to wear components and a permanent stock of parts: downtime is reduced to the strict minimum.

The gap widens with hardness

The higher the ABR and the Mohs index, the greater the WEIL advantage. It is precisely on the hardest rock that the mechanics make the difference.

Technical reference

Abrasiveness of quarry rock

Mohs hardness index and ABR abrasiveness index (kWh/t) for 16 commonly processed rocks. The higher the ABR, the faster the tool wear.

Highly abrasive (ABR > 0.30) Abrasive (0.15 – 0.30) Moderate (ABR < 0.15)
Rock Type Mohs ABR (kWh/t) Level
Corundum Mineral 9.0 0.55 Highly abrasive
Quartzite Metamorphic 7.0 0.48 Highly abrasive
Pure quartz Mineral 7.0 0.45 Highly abrasive
Chert / Flint Sedimentary 7.0 0.42 Highly abrasive
Basalt Igneous 6.0–7.0 0.38 Highly abrasive
Granite Plutonic 6.0–7.0 0.35 Highly abrasive
Rhyolite Volcanic 6.0–7.0 0.34 Highly abrasive
Porphyry Volcanic 6.0–7.0 0.32 Highly abrasive
Clinker Artificial 6.0–7.0 0.30 Abrasive
Gneiss Metamorphic 6.0–6.5 0.28 Abrasive
Hornblende Mineral 5.5–6.0 0.26 Abrasive
Garnet Mineral 6.5–7.5 0.25 Abrasive
Siliceous schist Metamorphic 5.5–6.5 0.22 Abrasive
Bauxite Lateritic 5.0–6.5 0.20 Abrasive
Silicified limestone Sedimentary 4.0–6.0 0.18 Abrasive
Soft limestone Sedimentary 3.0–4.0 0.06 Moderate

Indicative average values — the real abrasiveness depends on the local composition of the deposit. Our engineers refine the sizing from a sample of your rock.
