1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable downtime eroding your aggregate production margins? For plant managers and engineering contractors, the core challenges in primary crushing often stem from the stone crusher machine at the heart of your operation. Common pain points include:

Unscheduled Downtime & High Maintenance Costs: Frequent liner changes, unexpected component failures, and lengthy repair cycles halt your entire processing line. Every hour of stoppage can represent thousands in lost production and labor costs.
Inconsistent Output & Poor Particle Shape: A crusher that produces an excessive amount of flaky or elongated material downgrades product value, increases recirculating load, and creates bottlenecks in downstream screening and secondary crushing stages.
Rigid Configuration & Scalability Limits: Fixedcapacity plants struggle to adapt to changing feed material hardness or required product specifications, forcing costly workarounds or premature equipment replacement.
Excessive Energy Consumption: Inefficient crushing chambers and drive systems lead to disproportionately high power draw per ton of processed material, directly impacting your bottom line.

What if your primary stone crusher machine could deliver higher throughput with greater reliability, produce a more consistent product shape, and adapt to variable feed conditions without sacrificing efficiency?

2. PRODUCT OVERVIEW

The [Manufacturer/Model Series] is a heavyduty, stationary primary jaw crusher engineered for the initial reduction of hard rock, granite, basalt, and recycled concrete. Its robust design is focused on maximizing uptime and minimizing costperton in highvolume quarrying and mining applications.

Operational Workflow:
1. Large feed material (up to specified feed opening) is loaded into the vibrating grizzly feeder.
2. The material enters the deep crushing chamber where a powerful elliptical jaw motion applies compressive force.
3. Crushed product discharges at the bottom setting, with the closedside setting (CSS) directly determining the final topsize of the output.
4. The crushed aggregate is conveyed to downstream screening and secondary crushing stages.

Application Scope: Ideal for primary crushing duty in granite quarries, basalt mines, and largescale construction aggregate plants. Suitable for feed sizes up to 1200mm.

Key Limitations: Not designed for abrasive silica sand or very soft limestone as a dedicated primary unit; a different crusher type may offer superior efficiency for those specific materials.

3. CORE FEATURES

Patented Quattro Movement Jaw Design | Technical Basis: Optimized kinematics creating an aggressive elliptical stroke at the top of the chamber | Operational Benefit: Enhances nip angle and pulldown effect for faster reduction, reducing bridging and improving throughput by up to 15% compared to conventional designs | ROI Impact: Higher tons per hour (TPH) lowers fixedcost allocation per ton of output.

Hydraulic Toggle & Adjustment System | Technical Basis: Replaces traditional mechanical toggle plates with a dualacting hydraulic cylinder | Operational Benefit: Enables remote adjustment of the closedside setting (CSS) for quick product size changes and provides automatic overload protection by releasing under uncrushable conditions | ROI Impact: Eliminates manual shim adjustments, saving 12 hours of labor per changeover; prevents catastrophic damage from tramp metal.

HeavyDuty Fabricated Frame with StressRelieving | Technical Basis: Computermodeled, welded steel construction subjected to postweld heat treatment (PWHT) | Operational Benefit: Eliminates residual stresses for exceptional fatigue resistance and longevity under cyclical loading | ROI Impact: Extends structural service life beyond industry norms, protecting your capital investment.

Integrated Motor Base & Belt Guard | Technical Basis: Unified baseplate for crusher, motor, and drive guards manufactured as one unit | Operational Benefit: Simplifies installation by ensuring perfect drive alignment reduces site assembly time by approximately 30% | ROI Impact: Lowers installation costs and eliminates premature Vbelt wear due to misalignment.

Advanced Liner Retention System | Technical Basis: Wedgelocked liner plates with replaceable cheek plates | Operational Benefit: Allows liner changes from above using standard tools; no backing compound required reduces changeout time by up to 50% | ROI Impact: Minimizes maintenance windows increases plant availability significantly over the crusher's lifetime.

Centralized Automated Greasing System (Optional) | Technical Basis: Programmable lubrication unit serving all major bearing points from a single station | Operational Benefit: Ensures optimal bearing lubrication intervals are met consistently reduces risk of bearing failure due to human error or missed greasing rounds | ROI Impact: Extends bearing service life by an average of 25%, as demonstrated in field data across multiple sites.

6. APPLICATION SCENARIOS

Granite Quarry Primary Crushing Plant Expansion

Challenge: A large granite quarry needed to increase primary circuit throughput by over 20% without expanding their plant footprint or primary feed conveyor infrastructure.
Solution: Replacement of two older jaw crushers with a single highcapacity JC140 unit featuring the Quattro movement design.
Results: Achieved a sustained throughput increase of 22%. The improved particle shape reduced recirculating load in the secondary cone circuit by an estimated 18%, leading to lower overall plant energy consumption per ton produced.

Recycled Concrete Aggregate (RCA) Production Facility

Challenge: Processing variable demolition concrete containing intermittent rebar posed high risks of uncrushable material causing downtime and potential damage.
Solution Installation of a JC140 equipped with the Hydraulic Toggle system for automatic overload release.
Results Over two years of operation,the hydraulic toggle has activated seven times due to large tramp metal preventing main frame or bearing damage Each event resulted in less than 15 minutes downtime compared potential multiday repairs documented similar sites without this protection
