Everything a quarry digitalization lead or EPC mechanical engineer needs to copy into a technical response: control architecture, telemetry tags, hybrid duty cycles and verified R&D metrics.
Figures below come from instrumented crushing plants under TerraForce field-service contracts. Verifiers are internal metrology plus third-party emissions or network audits where noted. Use them as tender annexes, not marketing averages.
| KPI | Latest | Verifier |
|---|---|---|
| IoT tag coverage on commissioned plants | 142 standard tags / circuit | ISO 15143-3 AEMP export audit |
| Hybrid jaw idle-fuel reduction vs diesel-only | 18% | On-plant fuel meter, 90-day pilot |
| Cone liner prediction lead time | 36–48 h before throw risk | Vibration + amperage model vs tear-down |
| Hydraulic cleanliness at factory gate | ISO 4406 18/16/13 | Bottle sample log per serial |
| Remote diagnostic first-time-fix | 71% | Field-service ticket database |
| R&D spend vs revenue (rolling 3 yr) | 6.4% | External financial review pack |
Load-sensing pumps on jaw CSS and cone tramp-release circuits hold pressure setpoints when feed density swings. Closed-loop logic prevents the common failure mode where a sticky chute starves the cone while the hydraulic pack overheats waiting for oil to move.
Edge gateways stream CSS position, motor amps, bearing temperature and screen vibration into a quarry dashboard. Alerts escalate to the regional parts hub so mantles and mesh panels leave the warehouse before the night shift loses tonnage.
Diesel gensets on hybrid jaws drop to low RPM during intermittent feed while electric motors keep conveyor and feeder continuity. Peak CSS force still comes from the hydraulic pack — electrification here targets idle burn, not fantasy full-battery primary crushing.
Primary crushing selection is still debated on hard-rock and recycling tenders. TerraForce stocks both machine classes; the table below mirrors how application engineers frame the choice before a flowsheet is frozen — not a sales preference.
| Dimension | Jaw Crusher | Impact Crusher |
|---|---|---|
| Feed hardness & structure | Simple compression chamber; wide feed-size tolerance; common primary for Mohs ≤ 9 limestone and granite | Impact rotors prefer medium-hard or friable feed; reinforced concrete and asphalt recycle well when rebar is pre-separated |
| Product shape | More elongated flakes possible; often needs a cone or tertiary stage for asphalt cube-shape specs | Higher cubicity in a single stage — preferred when highway asphalt aggregate shape is the award criterion |
| Wear & maintenance cost | Jaw plates and cheek plates; lower spare-part spend on abrasive rock when CSS is disciplined | Blow bars and apron liners wear faster on high-silica rock; metallurgy grade must match feed PSD |
| Typical TerraForce pairing | Jaw → cone → triple-deck screen for 350–800 t/h quarry circuits | Impact + magnet + finishing screen for urban recycled-concrete yards targeting ≤ 0.3% rebar by mass |
Choose jaw when feed includes large, hard lumps, site power is intermittent, or the EPC wants a low-complexity hydraulic pack with published CSS setpoints. Hybrid-electric idle cutbacks still apply because jaw duty cycles often wait on sticky feed.
Choose impact when finished-product cubicity or recycling throughput outranks liner life, and the yard can enclose the rotor for ≤ 78 dB at 7 m night permits. Impact is not a drop-in primary for oversize hard granite without a pre-screen.
Neither class is universally “better.” TerraForce quotes both only after feed F80, Mohs range, target gradation and noise limits are on the inquiry — otherwise the technology pack stays conceptual.
Application engineers publish these limits in the Technology Pack so tender responses do not over-promise idle-fuel cuts or tonnage on unsuitable feed.
The 18% idle-fuel cut versus diesel-only baselines was measured on intermittent night feed over a 90-day pilot. Continuous choke-fed hard-rock circuits see smaller savings because the hydraulic pack rarely drops to low RPM.
Hybrid-electric jaws still need a sized genset or grid kVA for peak CSS events. Sites that remain genset-only in season one must declare available kVA; we will not certify a full zero-diesel primary package without that figure.
36–48 h cone-liner lead time assumes ISO 15143-3 tag maps stay online and vibration sensors are not bypassed after commissioning. Plants that disable telematics lose prediction windows and revert to calendar-based changeouts.
Published output capacity (t/h) on dry limestone does not transfer to high-moisture recycled concrete. Screen vibration frequency (RPM) and spray-bar packages must be re-specified; dry-circuit tonnage is not promised on wet feed.
Verification path: request a serial-specific Technology Pack (ladder diagrams, tag dictionary, hybrid duty curves) or book a circuit audit with an application engineer — free sample liner metallurgy matching is available when feed PSD and CSS are supplied.
Request the Technology Pack PDF for ladder diagrams, tag dictionaries and hybrid duty-cycle curves. Packs are serial-specific once a plant configuration is frozen.
Share feed size, target t/h and whether you need hybrid, IoT-only or full digital-twin scoping — we return a capability map in five business days.
