Feed size · closed-side setting · vibration frequency · output capacity t/h · discharge opening — bench-verified for quarry, mining and tunnelling selection.
Four instrumentation cards summarize the parameters equipment managers and chief engineers audit when sizing a jaw / cone / screen string. Values are representative class mid-points from Sandvik validation runs — request serial-specific sheets for bid packages.
Downloadable outlines for procurement and mineral processing reviewers evaluating crushing plant claims before award.
Family certification covers jaw, cone and screen carriers sold into regulated markets with NOx + PM logs.
Aftertreatment packages synchronized with dealer training for DEF and DPF service on quarry fleets.
Wet and dry feed hysteresis maps become standard attachments to tender responses.
Field tablets capture vibration frequency against mesh changeouts for efficiency audits.
Trailer loads, conveyor angles and foundation reactions issued as CAD + PDF for civil reviewers.
Roadmap gate requires bench-validated rock UCS libraries before customer-facing release.
Two selection debates appear on almost every aggregate RFQ. Both sides are summarized so procurement can record a decision path — not a brochure winner.
In limestone and hard-rock primary crushing, buyers argue whether a jaw or an impact chamber delivers lower cost per ton of on-spec product.
Simple toggle geometry, lower liner cost and wide tolerance for feed hardness (Mohs ≤ 9). Preferred when blast fragmentation is coarse (feed size 900–1,200 mm) and downtime windows are short.
Higher cubicity for asphalt fractions, but wear cost rises fast on abrasive granite. Often wins as a secondary after a jaw primary when the tender weights product shape over liner life.
Fines recovery versus water and permit cost drives whether sand washing modules sit after the vibrating screen.
Sand washing and wet decks recover fine fractions and cut dust. Suited where water rights and settling ponds already exist and RCA / concrete sand specs demand washed product.
Dust-controlled dry screens avoid water infrastructure in arid pits. Trade-off: dust permit limits and baghouse load rise; fines recovery is usually lower than a wash plant.
Witness runs log feed size (mm), CSS (mm), vibration frequency (RPM) and output capacity (t/h) against the serial curve; data files ship with CE Machinery Directive 2006/42/EC packs when requested.
On request we supervise a 1–2 shift trial recording conveyor weigh-bridge tons, liner wear and ISO 4406 hydraulic samples for your rock class.
Compare jaw vs impact, wet vs dry and stationary vs mobile on feed size, CSS, t/h, liner cost and permit constraints — without naming competing OEMs in the bid file.
Ask for CSS curves, screen mesh tables or plant t/h models matched to your rock type and target gradation.
