Eight Engineering Disciplines · One Crushing Catalog

Hard-rock mining · aggregate quarries · asphalt base yards · C&D recycling · wet processing · tunneling spoil · ports · water conservancy — each discipline mapped to a Tier 4 Final certified jaw, cone, impact or screen class with published output capacity (t/h) bands.

Hard-Rock Mining

Primary jaws and secondary cones sized to mill-feed CSS with slurry-pump duty for wet circuits.

Aggregate Quarries

Mobile and stationary strings producing asphalt and concrete fractions with screen deck audits.

Road Base Production

Jaw/cone/screen trains matched to binder and base tonnage so paving crews never wait on stockpiles.

Building C&D Recycling

Impact crushers with magnets and air classifiers for reclaimed concrete and brick streams.

Wet Processing & Sand

Vibrating screens and sand wash modules recovering fines beside quarries and canal borrow pits.

Tunnel & Metro Spoil

Compact crushing packages for TBM spoil sizing before haul or reuse as engineered fill.

Ports & Marine Yards

Salt-ready screen frames and corrosion packages for quay aggregate and recycled fill loops.

Water Conservancy

Wet decks and jaw primaries for dam aggregate, riprap dressing and canal embankment fill.

Technical Requirements by Discipline

Use this map when your engineer of record asks which Metso class covers a given feed size, CSS or wet-process standard.

Discipline	Key Spec	Standard	Metso Class
Hard-Rock Mining	Feed size mm & CSS band	Mill-feed contract notes	Primary jaw + HP-class cone
Aggregate Quarries	Output capacity t/h	Asphalt / concrete fraction specs	Mobile jaw/cone/screen string
Road Base	Closed-side setting & cubicity	Highway base course briefs	Secondary cone + triple-deck screen
C&D Recycling	Impact chamber & magnet duty	Municipal recycled aggregate rules	Impact crusher + classifier
Wet Processing	Screen media & slurry-pump flow	Site geotech / wash plant brief	Wet screen + sand wash module
Tunnel Spoil	Operating weight & footprint	Urban envelope / ventilation limits	Compact jaw + screen package

Wet vs. dry mineral processing — which maximizes recovery?

Quarry and mine buyers often face this route choice before they buy screens or slurry pumps. Both paths are valid; the trade-off is water infrastructure versus fine-particle recovery.

Wet processing

Water-media wash plants and slurry circuits recover fines more reliably on clayey feed and many iron / sulphide streams. Wet decks plus sand wash modules raise saleable sand yield, but need slurry-pump wet ends, water recycling and geotech approval for settling ponds.

Dry processing

Air classifiers and dry screens avoid water infrastructure — preferred in arid pits and sites with no discharge permit. Recovery on sticky fines is weaker; dust control and screen-media blinding become the governing limits instead of slurry flow.

Metso maps wet-screen + slurry-pump packages only when site water and abrasion duty are known; dry circuits stay on vibrating screens and air classification until a wash plant brief exists.
