1. PAINPOINT DRIVEN OPENING

Are escalating maintenance costs and unplanned downtime eroding your aggregate production margins? Plant managers and engineering contractors consistently face critical operational challenges with their primary crushing and screening circuits. These include: inconsistent feed material causing crusher chokeups and screen blinding, leading to hours of lost production; excessive wear part consumption on liners and screen meshes from abrasive feeds, driving unsustainable operational expenses; and insufficient throughput or final product specification failures that compromise contract fulfillment. The compounding costs of reactive maintenance, energy inefficiency, and suboptimal yield directly impact your bottom line. Is your current equipment configuration equipped to handle variable feed stock? Can you reduce your costperton metric while maintaining product quality? A strategic upgrade to a highperformance primary crushing station is often the definitive solution.

2. PRODUCT OVERVIEW

This content details a TrackMounted Primary Jaw Crusher, a selfcontained, mobile crushing unit designed for the initial size reduction of quarried rock, demolition concrete, and mine ore. Its operational workflow is engineered for rapid deployment and highvolume output: 1) The integrated heavyduty vibrating grizzly feeder regulates material flow to the crusher, scalping out fines to reduce crusher load. 2) The robust jaw crusher chamber performs the primary crushing action, reducing large feed (up to 800mm) to a manageable size. 3) Crushed material is discharged onto the main product conveyor. 4) An optional side conveyor or magnetic separator can remove rebar and metals in recycling applications. This equipment is optimal for largescale quarrying, mining precrushing, and major infrastructure demolition projects requiring onsite primary reduction. It is not designed as a finishing plant for producing final aggregate specs without secondary crushing stages.

3. CORE FEATURES

6. APPLICATION SCENARIOS

Granite Quarry Expansion | Challenge: A quarry needed to establish a new primary crushing face over a kilometer from the fixed processing plant. Transporting runofquarry stone with haul trucks was costing over $0.80 per ton in fuel and labor. Solution: Deployment of a trackmounted primary jaw crusher at the new face site. The unit crushed material to 250mm, which was then conveyed via a series of shiftable conveyors to the main plant.

Results:
Eliminated over $120k in annual haulage costs.
Increased overall plant throughput by avoiding truck cycle time bottlenecks.
Achieved payback on the mobile unit in under 18 months.

Major Infrastructure Demolition Recycling |

Challenge:
A contractor won a project to process 200,000 tons of reinforced concrete from a demolished bridge within a strict urban timeline.
Onsite space was limited,and final product specs required clean,
crushed aggregate.Solution:
A trackmounted primary jaw crusher with an overband magnet was used as the frontline processing unit.It crushed concrete,
separated rebar,
and fed secondary units.All equipment was trackmounted for daily repositioning.
Results:
Processed over
5,
000 tons per day,
meeting the aggressive project schedule.Captured
98%
of ferrous metal for separate recycling revenue.Reduced offsite tipping fees by over
60%
through onsite processing.

7.COMMERCIAL CONSIDERATIONS

Pricing for a trackmounted primary jaw crusher is tiered based on capacity size,
specification level,
and optional features.Base configurations typically start in the upper sixfigure range.Optional features that affect price include:
hybrid dieselelectric drive systems,
dust suppression packages,
extended capacity feeders,
