Most quarry operations need fixed-plant industrial crushing equipment that Komplet America does not sell. Genuine quarry-scale work — multi-hundred-tph throughput, multi-shift operations, million-ton-per-year production — is the territory of large gyratory primary crushers, cone crushers for secondary and tertiary reduction, and vertical-shaft impactors for cubical fine product, all delivered as fixed plants by manufacturers focused on the industrial mining and aggregate category. Komplet does not compete in that category, and operators running at that scale should be looking at fixed-plant equipment from manufacturers focused on industrial mining and aggregate production.
There is, however, a narrow envelope where Komplet’s compact mobile crushing lineup fits a genuinely small rock-quarry operation: throughput at or under 160 US tph, modest annual production volume, mobility-driven operations, and a budget profile that does not support fixed-plant infrastructure. For that profile, the Komplet K-JC 805 mobile jaw crusher — Komplet America’s largest jaw crusher — is the right primary crusher recommendation. The K-IC 70 compact impact crusher can be deployed as optional secondary reduction behind the K-JC 805 for operations producing spec cubical aggregate.
Below, we walk through where this fit makes sense, where it does not, and what genuinely small quarry operators should know before specifying compact mobile equipment for quarry work.
Honest Scope: Quarry Work Komplet Does Not Cover
Before recommending any equipment, we need to be honest about what Komplet’s compact mobile lineup is and is not engineered for. The following quarry profiles are outside Komplet America’s scope:
- Industrial quarries — 500+ US tph fixed-plant operations, multi-million-ton-per-year production volumes, multi-shift continuous operations. The Komplet jaw crusher lineup tops out at the K-JC 805 (up to 160 US tph). Operations of this scale require fixed-plant primary gyratory crushers, secondary cone crushers, and vertical-shaft impactors at throughputs and design profiles that compact mobile equipment is not engineered to deliver.
- Mid-size to large commercial aggregate quarries — multi-county or regional aggregate producers running 200,000+ US tons per year as their primary business. Even at the upper end of compact-mobile capacity, the K-JC 805 typically does not have the headroom for sustained year-over-year production at this volume. These operations are better served by fixed-plant equipment in a higher throughput tier.
- Specialty industrial mineral and ore extraction — hard ore extraction (precious and base metals), specialty mineral processing for industrial chemicals, and high-tonnage continuous mining operations. These applications require purpose-built mining equipment that operates at much higher throughputs and under different design criteria than compact mobile crushers.
- Manufactured sand at industrial scale — large-scale specialty sand-making plants are outside Komplet’s compact-mobile category. The K-IC 70 produces a cubical aggregate well suited to many spec applications, but industrial manufactured-sand operations require dedicated VSI plants and supporting infrastructure.
- Asphalt milling, full-depth reclamation (FDR), and HMA plant production — road-rehabilitation milling, FDR, and hot-mix asphalt plant equipment are different equipment categories. Komplet processes recycled asphalt pavement (RAP) into reclaimable aggregate but does not compete in milling, FDR, or HMA plant production.
If your operation falls into any of these profiles, the right answer is fixed-plant industrial mining and aggregate equipment from manufacturers focused on that category — not Komplet. Komplet America would rather direct an operator to the right equipment elsewhere than oversell a compact mobile machine into a job it is not engineered for.
Where the K-JC 805 Fits in Quarry Work
Within the genuinely small rock-quarry envelope — operations sized below 160 US tph, with modest annual production volume and mobility-driven operating profiles — the K-JC 805 is the right Komplet primary crusher recommendation. The fit profile typically includes:
- Small commercial rock pits — local stone yards, regional aggregate suppliers operating at modest annual volumes, and contractor-owned rock pits feeding the contractor’s own work plus limited outside sales.
- Multi-face or multi-pit operations — operations that work multiple smaller faces or pits within the property and benefit from a tracked self-propelled crusher walking itself between locations rather than requiring a fixed plant at each face.
- Operations following an active face — operations that work outward from a starting face over time and need crushing capacity that follows the active face rather than committing to a fixed-plant location.
- Specialty stone production — hardscape stone, decorative aggregate, niche commercial stone production at modest volumes, where the operation does not need industrial-scale throughput and benefits from compact mobile flexibility.
- Operations transitioning from stationary contract crushing — operators previously paying outside contract crushers who want to bring crushing in-house at a scale that does not justify fixed-plant infrastructure.
If your quarry operation does not fit one of these profiles — particularly if you are running sustained throughput above 160 US tph or need a fixed-plant configuration for continuous operations — the K-JC 805 is not the right tool, and we would rather tell you that up front than sell you a machine that will not meet your operational needs.
The K-JC 805: Komplet America’s Largest Jaw Crusher
The K-JC 805 is the largest jaw crusher in the Komplet America lineup and the only one we recommend as a primary crusher for quarry work. Verified specifications:
- Engine: 130 hp Tier 4F diesel
- Production: up to 160 US tph
- Jaw opening: 31″ × 21″
- Output size: approximately 1.2″ to 4.7″
- Operating weight: 49,600 lb
- Magnetic separator: standard
- Komplet Connect remote monitoring: standard
- Tracks: rubber tracks standard, optional metal tracks available
- Wireless remote control: standard for all functions
- Classification: semi-pro
- Verified pricing: $454,366.25 (base unit + magnetic separator + side conveyor)
The K-JC 805 fits a small rock-quarry operation in the same way it fits other heavier-duty applications: large jaw opening for primary feed, compression-based reduction that handles hard, abrasive rock predictably, and the mobility to walk itself between processing locations. The 49,600 lb operating weight is the upper end of what transports on standard heavy-duty trailers — confirm exact hauling and permitting requirements with your transport provider before scheduling moves.
Optional Secondary: K-IC 70 for Spec Cubical Aggregate
Some quarry operations supply spec aggregate to hot-mix asphalt plants or concrete batch plants, where the end use requires cubical particle shape rather than the more elongated particles a typical jaw crusher produces. For those operations, Komplet’s K-IC 70 compact impact crusher can be deployed as optional secondary reduction behind the K-JC 805. Verified specifications:
- Engine: 100 hp Tier 4F diesel
- Production: up to 90 US tph
- Inlet: 25″ × 20″
- Output size: 3/4″ to 3-1/4″
- Operating weight: 28,600 lb
- Magnetic separator: standard
- Dust suppression: standard
- Output profile: premium cubical aggregate; ideal for RAP reduction and DOT-spec material
- Verified pricing: $285,948.00 (base unit + magnetic separator)
The K-IC 70 uses blow bars rather than jaw plates as the primary consumable wear part. Impact crushers wear faster on highly abrasive rock than jaw crushers, so the K-IC 70 is best deployed as secondary reduction behind the K-JC 805 — letting the jaw crusher take the abrasive primary work and the impact crusher take a controlled, smaller-feed secondary stage that produces cubical output. Operations producing aggregate for road base, drainage, fill, and similar applications where particle shape is not critical typically do not need the secondary impact stage.
If your quarry rock is highly abrasive (granite, basalt, hard limestone) and you do not need cubical output, the K-IC 70 is generally not the right addition — its wear-part service life on highly abrasive primary feed will be substantially shorter than the jaw crusher’s.
Pairing with Screening and Conveying
Quarry crushing rarely runs alone. The complete operation typically includes the primary crusher, a vibrating scalping screener for product cuts, and a tracked mobile conveyor for stockpile management. For a K-JC 805 quarry spread, the standard Komplet pairings are:
- K-JC 805 → Kompatto 5030 (up to 280 US tph) or Kompatto 124 (up to 350 tph) → K-TC 460 tracked mobile conveyor
- K-JC 805 → K-IC 70 (secondary cubical reduction) → Kompatto 5030 → K-TC 460 (typical spec-aggregate spread)
Screener throughput should match or exceed crusher throughput so the screen does not become the bottleneck. The Kompatto 5030 is Komplet America’s best-selling screener and fits most K-JC 805 quarry spreads; the Kompatto 124 is the largest scalping screen in the Komplet lineup for operations approaching the upper end of K-JC 805 throughput.
Mobility for Small Quarry Operations
All current Komplet crushing equipment is tracked, self-propelled, and operated by wireless remote — there is no stationary or fixed-plant configuration in the Komplet lineup. For a small quarry operation, mobility delivers concrete operational benefits:
- Operating from multiple faces or pits within the property — the K-JC 805 walks itself between locations on its own tracks rather than requiring a haul truck or crane to relocate it
- Repositioning to follow the active face as material extraction progresses — important on operations that work outward from a starting face over time
- Setup at a temporary processing location for a specific batch of material, then redeployment elsewhere when the batch is done
- Faster initial setup compared to fixed-plant infrastructure — Komplet equipment is typically operational within hours of arrival rather than the days or weeks required for fixed-plant installation
- Operating across multiple smaller operations — a single mobile spread serving multiple smaller pits across a county or region
For industrial-scale quarries running fixed-plant operations at 500+ US tph, mobility is not the right design criterion — those operations benefit from fixed plants that maximize throughput at a single dedicated location. For genuinely small quarry operations within the K-JC 805’s envelope, the mobility advantages typically outweigh the throughput tradeoff against fixed-plant alternatives.
Operating Costs and Total Cost of Ownership
Sticker price is the most visible cost component but typically a smaller portion of equipment cost over its operating life. Quarry-specific operating cost components for the K-JC 805:
Wear Parts
Quarry rock is harder on wear parts than recycled concrete or asphalt. Manganese steel jaw plates are designed to wear and be replaced; service life depends on rock hardness and abrasivity. Soft limestone may deliver substantially more operating hours per plate set than hard granite or basalt. The K-JC 805 allows plate rotation, extending total plate life. Track wear patterns and rotate at the OEM-specified wear point. If a K-IC 70 is deployed as secondary, its blow bars will wear faster than the jaw plates on highly abrasive rock — plan parts inventory accordingly.
Komplet Connect Remote Monitoring
Komplet Connect remote monitoring is standard on the K-JC 805. The system provides remote operating data and diagnostic visibility to the operator and to Komplet America’s service team. For quarry operations managing equipment across multiple locations or shifts, the data feed enables predictive maintenance, service-interval tracking, and remote diagnostic support that meaningfully reduces unplanned downtime — typically the largest hidden operating cost most quarry operators do not track.
Dust Suppression
Factory-integrated water-spray dust suppression is available as an option on the K-JC 805 (it is standard on the K-JC 503 and K-IC 70 only). For quarry operations that include silica-bearing rock, specifying dust suppression on the K-JC 805 at order is a meaningful piece of OSHA Table 1 wet-method engineering controls. Confirm exact configuration with your authorized Komplet dealer.
Financing through Komplet Capital
Komplet Capital — Komplet America’s in-house financing arm — offers 100 percent financing on new and certified pre-owned Komplet equipment, with 24-hour approval and multi-year repayment options. Section 179 tax treatment may apply on qualifying equipment, and bonus depreciation rules change year to year — consult your tax advisor for current limits and applicability to your specific operation.
Pre-Owned Capital Savings
Komplet’s certified pre-owned program delivers verified-history equipment with OEM parts support and the same authorized service network, typically at meaningful capital savings versus new. For a small quarry operation sizing into a complete K-JC 805 spread (crusher + screener + conveyor) at a budget that would otherwise cover fewer machines new, pre-owned can deliver the right balance of capital efficiency and operating reliability. Confirm specific pre-owned availability and pricing with Komplet America at 908-369-3340.
Environmental and Regulatory Compliance
OSHA Silica Compliance
OSHA’s respirable crystalline silica standards (29 CFR 1926.1153 for construction; 29 CFR 1910.1053 for general industry, which typically covers quarry production operations) set a Permissible Exposure Limit of 50 µg/m³ as an 8-hour time-weighted average and an Action Level of 25 µg/m³. Most quarry operations contain silica-bearing rock (granite, sandstone, hard limestone), and crushing operations generate respirable silica dust at the source unless engineering controls are in place. Specifying dust suppression on the K-JC 805 at order is a meaningful piece of OSHA Table 1 wet-method engineering controls.
EPA Tier 4 Final Emissions
All current Komplet equipment sold in the United States meets EPA Tier 4 Final emissions standards for non-road diesel engines — required for new-equipment sale in the U.S. and meaningful for quarry operations near residential areas, on federally funded projects, or in jurisdictions with emissions restrictions. Diesel exhaust fluid (DEF) infrastructure is required, but DEF is widely available and the engine integration is well-engineered.
State and Local Quarry Permitting
Quarry operations are typically subject to state and local permitting requirements covering operating hours, dust and noise emissions, water management, blasting (where applicable), reclamation plans, and similar conditions. Equipment selection should align with the operation’s permit conditions — particularly noise and dust limits that may favor certain equipment configurations. Consult your state environmental and mining/quarrying regulators for specific permit requirements; Komplet America does not provide quarry permitting consulting.
Frequently Asked Questions
Why does Komplet only recommend the K-JC 805 for quarry work?
The K-JC 805 is the largest jaw crusher in the Komplet lineup, with a 31″ × 21″ jaw opening and up to 160 US tph production. Smaller Komplet crushers (K-JC 503, K-JC 604, K-JC 704 PLUS) are engineered for contractor, demolition, recycling, and stone-yard applications, not quarry primary feed. They do not have the jaw opening or the production capacity to keep up with sustained quarry production. For genuinely small rock-quarry operations within a 160 US tph envelope, the K-JC 805 is the right Komplet recommendation. Operations needing more than 160 US tph should be looking at fixed-plant industrial equipment outside Komplet’s category.
What if my quarry operation needs more than 160 US tph?
Then Komplet is not the right manufacturer for your primary crusher, and we would rather tell you that than oversell the K-JC 805 into a job it is not engineered for. Operations needing sustained throughput above 160 US tph should be evaluating fixed-plant industrial mining and aggregate equipment from manufacturers focused on that category — large gyratory primary crushers, cone crushers for secondary and tertiary reduction, and supporting infrastructure at industrial scale.
Can the K-JC 805 handle granite or basalt?
Yes. The K-JC 805’s compression-based jaw reduction handles hard, abrasive rock at its production scale. Wear-part service life on hard, abrasive rock will be shorter than on softer material like limestone — plan jaw plate rotation and replacement accordingly. The K-IC 70 is generally not the right addition as primary on highly abrasive rock; if it is deployed at all on a granite or basalt operation, it should run only as secondary behind the K-JC 805 with controlled smaller feed.
Do I need the K-IC 70 for my quarry?
Only if your end customers require cubical particle shape. Hot-mix asphalt plants and concrete batch plants prefer cubical aggregate because it locks and bonds better than the more elongated particles a jaw crusher produces. If your quarry supplies aggregate for spec asphalt or concrete batch plant feed, the K-IC 70 can be deployed as secondary reduction behind the K-JC 805 to produce cubical output. If your quarry produces aggregate for road base, drainage, fill, or other applications where particle shape is not critical, you typically do not need the K-IC 70 — jaw crusher output running directly to a screener delivers the right product.
Is the K-JC 805 a fixed-plant crusher?
No. The K-JC 805 is tracked, self-propelled, and operated by wireless remote. It is a compact mobile machine. There is no fixed-plant or stationary configuration in the Komplet lineup. If your operation requires a fixed-plant setup, you should be evaluating equipment from manufacturers focused on industrial-mining fixed plants — not Komplet.
How does the K-JC 805 transport between sites?
On a standard heavy-duty trailer. The 49,600 lb operating weight is at the upper end of what transports on heavy-duty trailers, and exact permitting requirements vary by jurisdiction and route. Confirm hauling logistics with your transport provider before scheduling moves between sites. Within a single property, the K-JC 805 walks itself between processing locations on its own tracks under wireless remote control.
What warranty applies to the K-JC 805?
All new Komplet equipment, including the K-JC 805, comes with a 1-year / 1,000-hour warranty (whichever is earlier). Komplet America stocks parts in New Jersey and ships to wherever the equipment is operating. Confirm warranty terms and pre-owned equipment warranty options with your authorized Komplet dealer or with Komplet America at 908-369-3340.
Does Komplet sell mining equipment?
No. Komplet’s compact mobile crushers serve aggregate quarries, contractor-owned rock pits, and stone yards at the small scale within a 160 US tph envelope. Industrial-scale mining (heavy ore extraction, large continuous mining, multi-shift fixed-plant operations) requires different equipment than the Komplet compact mobile lineup, and Komplet America does not compete in that category. Operators in industrial mining should evaluate equipment from manufacturers focused on the mining and metallurgical-processing category.
Final Thoughts
Most quarry operations need fixed-plant industrial crushing equipment that Komplet America does not sell, and the most useful thing we can do for an operator at that scale is direct them to manufacturers focused on industrial mining and aggregate production. For genuinely small rock-quarry operations within a 160 US tph envelope — operations sized for the K-JC 805’s capacity, oriented around mobility, and budgeted to compact mobile rather than fixed-plant infrastructure — the K-JC 805 is the right Komplet recommendation, with the K-IC 70 as optional secondary behind it for spec cubical aggregate output.
Right-sizing equipment to the operation honestly matters more than maximizing what Komplet might sell. If your quarry fits the K-JC 805 envelope, we are confident in the recommendation. If it does not, the right answer is somewhere else.
