Engineering Discipline Grid

Eight Crushing Disciplines · One Sandvik Catalog.

Aggregate production · hard-rock mining · tunnelling rock tools · recycling · foundation drilling — every discipline mapped to a Tier 4-ready crushing or drilling class.

Disciplines Project Engineers Specify Against

Design institutes and EPC technical directors rarely buy “a crusher.” They buy a discipline outcome — asphalt fractions, mill feed, tunnel spoil handling or helical pile installation. The grid below maps each outcome to the Sandvik machine class your tender should name.

Aggregate Production

Jaw + cone + vibrating screen + conveyor trains for limestone and granite quarries.

Hard-Rock Mining

Primary jaw / gyratory feed into cone circuits sized for abrasive mill feed.

Tunnelling Rock Tools

Top-hammer and DTH bits matched to UCS with compact spoil crushing options.

C&D Recycling

Impact crushers, magnets and sand washing modules for urban RCA plants.

Foundation Drilling

Drilling & piling tools with torque and penetration depth guidance for civil yards.

Mobile Crushing

Trailer-mounted jaw / cone / screen strings for temporary quarry expansions.

Wet Processing

Sand washing and wet screen decks where recovery of fines outweighs water cost.

Dry Processing

Dust-controlled dry screening for arid pits where wet plants are impractical.

Technical Requirements by Discipline

Use this comparison when your mechanical engineer needs a one-page map from discipline to key specification, governing standard and Sandvik class range. The table is intentionally sparse so chief engineers can paste rows into tender appendices without rewriting brochure language.

Where wet versus dry mineral processing is still debated on your site, note that Sandvik can pair the same jaw / cone primary string with either wet wash modules or dry dust-controlled screens — the decisive inputs remain water availability, fines recovery targets and permit dust limits, not marketing preference.

Discipline	Key Spec	Standard	Sandvik Class
Aggregate Production	Throughput t/h & CSS mm	ISO 21873	CX-class 200–1,500 t/h
Hard-Rock Mining	Feed size mm & abrasive index	ISO 21873	JX / CX mining packs
Screening	Vibration frequency RPM & mesh	ISO 5048 guidance	VS 2–4 deck classes
Tunnelling Tools	Bit life vs UCS	EN rock-tool practice	RT top-hammer / DTH
Foundation Drilling	Torque kN·m & depth m	EN 791	DR-class 80–450 kN·m
Recycling	Metal separation & RCA fraction	Local RCA specs	IX impact + wash
