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 center on three critical areas:

Unscheduled Downtime & High Maintenance Costs: Frequent liner changes, unexpected component failures, and bearing issues can halt your entire processing line. Industry data indicates that for a midsized quarry, every hour of crusher downtime can result in over $2,000 in lost production and labor costs.
Inconsistent Output & Poor Particle Shape: Feed variability leads to fluctuating product gradation and an excess of flaky or elongated particles, which compromises downstream process efficiency and final product value.
Excessive Energy Consumption & Low Throughput: Older or poorly designed jaw crushers operate with high specific energy consumption (kWh/ton), directly impacting your bottom line while struggling to meet increasing production targets.

Is your primary crushing station a bottleneck or a reliable asset? The solution lies in selecting a jaw crusher engineered not just to break rock, but to optimize total cost of ownership.

2. PRODUCT OVERVIEW: HEAVYDUTY JAW CRUSHER

This heavyduty jaw crusher is engineered for primary crushing applications in mining, quarrying, and largescale construction recycling. It is designed to process hard rock types such as granite, basalt, and iron ore, as well as demolition concrete.

Operational Workflow:
1. Feed Intake: Large feed material (up to 80% of the feed opening dimension) is loaded into the vibrating grizzly feeder (optional), which bypasses fines to increase capacity.
2. Crushing Action: Material enters the crushing chamber where a robust eccentric shaft drives a moving jaw plate against a fixed jaw plate in a compressive "chewing" motion.
3. Discharge Setting Adjustment: The closedside setting (CSS) is hydraulically adjustable from a central control point, allowing quick changes for different product specifications without stopping the crusher.
4. Product Discharge: Crushed material exits at the bottom of the chamber, with the discharge opening determining the final top size.

Application Scope & Limitations:
Scope: Ideal for stationary primary crushing plants, portable wheeled plants, and mobile trackmounted units requiring high capacity on abrasive materials.
Limitations: Not suitable for sticky or plastic materials (e.g., clayrich ore) without prescreening. Maximum feed size is constrained by the machine's gape dimension.

3. CORE FEATURES

Deep Crushing Chamber & Optimized Kinematics | Technical Basis: Increased nip angle and longer crushing stroke | Operational Benefit: Higher reduction ratio per pass and improved throughput of slabby material | ROI Impact: Reduces need for secondary stage recirculation, lowering energy costs per ton by up to 15%.

Hydraulic Toggle Relief System | Technical Basis: Replaces traditional mechanical toggle plates with hydraulic cylinders | Operational Benefit: Automatically protects the crusher from tramp metal and uncrushables by allowing the jaw to open wider; enables easier clearing of chamber blockages | ROI Impact: Prevents catastrophic damage to pitman and bearings; field data shows a 90% reduction in downtime from tramp iron events.

HeavyDuty Fabricated Frame | Technical Basis: Stressrelieved steel plate construction with reinforced ribs | Operational Benefit: Provides longterm structural integrity under maximum loading conditions, resisting fatigue and deformation | ROI Impact: Extends operational lifespan beyond industry average; reduces longterm capital expenditure on replacement structures.

Centralized Greasing System | Technical Basis: Singlepoint connection for all major bearing lubrication points | Operational Benefit: Enables safe, rapid, and thorough lubrication during routine maintenance windows without accessing multiple ports | ROI Impact: Standardizes maintenance procedure; industry testing demonstrates a 40% reduction in scheduled lubrication service time.

Wedge Lock Jaw Die Fastening System | Technical Basis: Mechanically locked wedges secure jaw plates without backing material or resin | Operational Benefit: Allows faster jaw plate changeouts with standard tools; creates a rigid support that prolongs plate life | ROI Impact: Reduces liner change downtime by approximately 30%, directly increasing plant availability.

6. APPLICATION SCENARIOS

Granite Quarry Primary Crushing Station

Challenge: A large granite quarry faced frequent downtime due to uncrushable drill steel remnants entering the primary crusher feed, causing catastrophic toggle plate failure every 68 weeks.
Solution: Replacement of the existing primary jaw crusher with our JC140 model equipped with a Hydraulic Toggle Relief System.
Results: In the first year of operation, three tramp iron events were safely cleared via hydraulic release in under one hour each—with no component damage. This eliminated an estimated 72 hours of unplanned downtime and $45k in associated repair parts/labor annually.

LargeScale Infrastructure Project – OnSite Aggregate Production

Challenge: A major dam construction project required consistent production of highquality base material from excavated basalt onsite but had limited space for complex multistage setups.
Solution: Implementation of two trackmounted JC140 jaw crushers fed directly by excavators.
Results: The plants achieved an average throughput of 750 tph each at a consistent CSS of 200mm. The deep chamber design produced wellshaped aggregate that met spec without secondary shaping circuits, saving an estimated $12 per ton versus offsite procurement.
