1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable downtime eroding your project margins? For plant managers and contractors, the reliability of primary crushing is nonnegotiable. Common challenges with suboptimal stone crusher machines include:
Unscheduled Downtime: Frequent mechanical failures and lengthy component changes halt your entire processing line, costing thousands per hour in lost production.
High Wear Part Consumption: Premature failure of jaws, liners, and blow bars due to inferior metallurgy or design leads to excessive spare parts inventory and labor costs.
Inconsistent Output & Product Shape: Unreliable crushing chambers produce poor particle size distribution, negatively impacting downstream screening efficiency and final product quality.
Excessive Energy Draw: Inefficient drive systems and crushing kinematics result in higherthannecessary power consumption per ton of material processed.
Limited Configuration Flexibility: Fixed designs that cannot adapt to changing feed materials or final product specifications force operational compromises.

What if your primary crusher could deliver predictable performance, lower costperton, and adapt to your specific site requirements? The solution lies in selecting a purposeengineered OEM stone crusher machine built for affordability through total cost of ownership, not just initial price.

2. PRODUCT OVERVIEW

The [Manufacturer/Model Series] is a robust, stationary primary jaw crusher engineered for highvolume reduction of hard rock, granite, basalt, and river gravel. Its design prioritizes structural integrity and operational simplicity for longterm reliability in demanding quarry and mining applications.

Operational Workflow:
1. Feed Intake: Large feed material (up to specified feed opening) is loaded into the vibrating grizzly feeder (optional), which bypasses fines to optimize chamber loading.
2. Crushing Action: Material enters the deep, symmetrical crushing chamber where a highinertia flywheel and optimized nip angle facilitate powerful compressive crushing.
3. Discharge & Regulation: Crushed material exits at the bottom with a consistent discharge gap setting, adjustable via a hydraulic or mechanical shim system to control final product size.

Application Scope: Ideal for primary crushing stations in aggregate production, mining operations, and largescale construction waste recycling. Suitable for feed sizes up to 1200mm and compressive strengths up to 320 MPa.

Limitations: Not designed for abrasive recycling applications without specific liner options. Requires a stable concrete foundation and appropriate upstream feeding equipment for optimal performance.

6. APPLICATION SCENARIOS

Granite Quarry Expansion, Southeast Asia Challenge:

A large aggregate producer needed to double primary capacity but was constrained by limited plant footprint and high local maintenance labor costs. Their existing crushers required frequent liner changes causing significant downtime.

Solution:

Installation of two JC160 OEM jaw crushers configured with hydraulic toggle systems and automated lubrication packages. The deepchamber design accommodated the variable granite hardness without bridging.

Results:

Plant availability increased from ~82% to over 91%. Liner changeout time reduced from two shifts (~16 hours) per machine to under one shift (<8 hours). The project achieved its capacity target within the existing footprint layout.

Basalt Aggregate Production for Rail Ballast Challenge:

A contractor on a major rail infrastructure project faced strict particle shape requirements (high cubicity index) for ballast material. Their existing primary crusher produced excessive flaky material, overloading the secondary cone crushers and failing spec consistently.

Solution:

Replacement of the primary unit with our OEM stone crusher machine featuring the optimized chamber geometry specifically tuned for abrasive basalt applications.

Results:

Postcrushing cubicity improved by an average of 15%. Recirculating load to secondary stage decreased by approximately 25%, allowing the entire circuit to meet daily tonnage specifications reliably. Wear life on secondary crusher liners saw a corresponding increase due to better feed shape.
