1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable downtime eroding your aggregate or mining project margins? Primary crushing stages present persistent challenges: excessive wear part consumption from abrasive feed material, unplanned stoppages due to tramp metal or uncrushables, and throughput bottlenecks that limit downstream process efficiency. Each hour of unscheduled maintenance represents significant lost revenue. How do you achieve consistent, highvolume reduction of hard rock while controlling maintenance costs and protecting your capital investment from catastrophic damage? The solution requires a robust primary crusher engineered for reliability and operational costperton efficiency.

2. PRODUCT OVERVIEW

The JC5000 is a highcapacity, singletoggle jaw crusher designed for heavyduty primary crushing in stationary quarrying, mining, and demolition recycling applications. Its operational workflow is engineered for simplicity and resilience: (1) Large feed material (up to 1.4m edge length) is introduced into the deep, nonchoking crushing chamber. (2) The aggressive elliptical jaw motion applies high inertia force for effective nipangle breaking of hard, abrasive materials like granite, basalt, and iron ore. (3) The crushed product discharges via gravity with a consistent CSS (Closed Side Setting), ready for secondary processing. The JC5000 is optimized for hightonnage primary reduction; it is not intended for fine crushing or as a mobile unit without a dedicated heavyduty chassis.

6. APPLICATION SCENARIOS

Hard Rock Quarrying – Granite Aggregate Production

Challenge: A large granite quarry faced excessive wear costs and unpredictable downtime from occasional bucket tooth fragments entering the primary crusher.
Solution: Implementation of a JC5000 Jaw Crusher with its hydraulic toggle protection system.
Results: Field data shows a complete elimination of major damage events from tramp metal. Combined with extended jaw die life, the site reported a 22% reduction in primary crushing costperton over a full operating year.

Mineral Processing – Primary Iron Ore Crushing

Challenge: A processing plant required higher primary throughput to feed a new beneficiation line but was constrained by space limitations for a larger crusher footprint.
Solution: A JC5000 was selected for its high capacitytofootprint ratio and ability to handle dense, abrasive ore.
Results: The installation achieved the required 1,350 mtph throughput within the existing footprint. Plant managers noted consistent discharge gradation improved performance of the downstream secondary cone crusher circuit.

8. FAQ

Q1: Is the JC5000 compatible with our existing primary feed arrangement and discharge conveyor?
A1: Yes. Our engineering team conducts presale interface reviews using your layout drawings to ensure compatibility with feed hoppers/rock boxes and provide detailed chute recommendations for your discharge conveyor.

Q2: What is the expected operational noise level?
A2：Industry testing demonstrates sound power levels typically range between 115120 dB(A). We provide specifications for acoustic enclosures which are often recommended or required in certain jurisdictions.

Q3：How does the hydraulic toggle affect routine maintenance compared to mechanical systems?
A3：It simplifies it significantly。There are no mechanical toggle plates，seats，or tension rods to maintain。The hydraulic system requires standard fluid checks，and cylinder seals are serviceable items。

Q4：Can you supply wear parts compatible with other crusher brands we operate?
A4：We manufacture parts exclusively for our machinery。Using nonOEM parts can void warranty protections。However，our logistics network is structured for rapid delivery of genuine wear parts globally。

Q5：What training is provided for our maintenance crew？
A5：Comprehensive onsite training covering operation，daily checks，CSS adjustment，and key replacement procedures（jaw dies，bearing cartridges）is included with installation。

Q6：What is the typical lead time from order placement？
A6：Lead times vary based on global production schedules but typically range from XXXX weeks。We provide firm timelines upon project commitment。

Q7：Does pricing include commissioning？
A7：Base equipment pricing typically excludes field commissioning。However，professional commissioning by factorytrained technicians is strongly recommended as part of a purchased service package。
