Frequently Asked Questions — Metso Crushing Guide

Use a cone when you need a tighter closed-side setting band, cubical product and stable throughput into asphalt or concrete fractions. Keep the jaw as the primary for feed sizes above roughly 600–800 mm where compressive crushing is more efficient. Our Solutions matcher walks through jaw versus cone checkpoints with feed size and abrasion index inputs.

Choose a jaw when blasted feed is large and hard (broad Mohs tolerance, simpler liner swaps). Choose an impact chamber when product cubicity matters more than liner cost on softer limestone or C&D concrete. Impact is rarely economical as the primary on abrasive granite above ~150 MPa UCS — see the Solutions trade-off module for both arguments side by side.

On hard granite with high silica, jaw plate life commonly lands between 350–700 operating hours depending on feed size distribution and CSS discipline. We gauge plate thickness at planned shutdowns and quote OEM-profile replacements from the nearest parts hub.

Buyers usually request feed size, CSS range, output capacity (t/h), operating weight, hydraulic system pressure and emissions package. We confirm those bands on quotation for a named rock and duty cycle — published ranges are directional until site samples are reviewed.

Yes. Parts desks consolidate mantle/concave kits, screen decks and slurry-pump wet ends so remote quarries receive one freight event. Critical seals and hydraulic kits can be air-freighted when the outage cost exceeds freight.

Mobile plants destined for regulated pits ship with DPF + SCR aftertreatment and documentation so municipal and highway tenders can attach emissions evidence without re-testing each unit.

Contracted sites target under 18-hour mean time to repair on critical crushers. Local hubs stock fast-moving liners and screen media; non-stock chamber kits ship from regional distribution centres, often overnight in major markets.
