H1: Optimize Your Aggregate Production with a Durable Primary Jaw Crusher

Are you facing escalating operational costs due to frequent component wear and unplanned downtime in your primary crushing stage? Does inconsistent feed size from your quarry lead to chokefeeding or cavity loss, reducing your plant's overall throughput? Are you struggling to balance the need for highcapacity fragmentation with manageable energy consumption and maintenance labor hours? For plant managers and engineering contractors, these challenges directly impact profitability. The solution lies in selecting a primary jaw crusher engineered not just to crush, but to optimize your entire downstream process for reliability and costperton efficiency.

Product Overview: HeavyDuty Primary Jaw Crusher

This equipment is a stationary, singletoggle primary jaw crusher designed for the first stage of size reduction in quarrying, mining, and largescale construction recycling applications. Its operational workflow is built for continuous, highvolume processing:
1. Feed Intake: Oversized raw material (ROM) is loaded into the vibratory feeder and directed into the deep, nonchoking crushing chamber.
2. Compressive Crushing: The robust eccentric shaft drives the moving jaw plate in an elliptical motion, applying immense compressive force against the fixed jaw to fracture the material.
3. Discharge Setting Adjustment: The CSS (Closed Side Setting) is hydraulically adjustable from the control panel or manually via shim plates, allowing precise control over output product size without stopping the machine.
4. Discharge & Conveyance: Crushed material exits through the bottom discharge opening onto a main conveyor belt for transport to secondary crushing or screening stages.

Application scope includes processing hard rock types like granite, basalt, and abrasive ores. Its primary limitation is product shape; jaw crushers produce more elongated particles compared to cone crushers, which may be a consideration for certain highspec aggregate products.

Core Features: Engineered for Demanding Duty Cycles

Hydraulic Toggle & Adjustment System | Technical Basis: Integrated hydraulic cylinder replaces mechanical toggle plates | Operational Benefit: Enables safe, rapid clearing of tramp metal and uncrushable material without stopping the crusher. Allows for remote CSS adjustment under load in certain models. | ROI Impact: Reduces downtime for chamber clearing by up to 80%, protecting major components from catastrophic damage.

HeavyDuty Fabricated Steel Frame | Technical Basis: Stressrelieved, modular frame design with reinforced ribbing | Operational Benefit: Provides exceptional structural integrity to withstand decades of high cyclic loading and vibration without fatigue failure. | ROI Impact: Eliminates framerelated failures as a lifecycle cost concern, extending the operational life of the capital asset.

Optimized Crushing Chamber Geometry | Technical Basis: Computermodeled kinematics and deep symmetric chamber design | Operational Benefit: Promotes continuous material flow, minimizes bridging, and increases capacity per unit of installed power. Delivers a consistent nip angle for uniform breakage. | ROI Impact: Field data shows a 1015% increase in throughput tonnage compared to older chamber designs with similar motor ratings.

HighInertia Flywheels | Technical Basis: Precisely balanced cast steel flywheels store kinetic energy | Operational Benefit: Smoothens power demand peaks during each crushing cycle, reducing stress on the drive motor and Vbelts. Maintains momentum under heavy loading conditions. | ROI Impact: Lowers peak current draw (amps), contributing to reduced energy costs and longer component life in the drive train.

EasyMaintenance Design | Technical Basis: Spherical roller bearings on both eccentric shaft and pitman; accessible lubrication points | Operational Benefit: Bearings are sized for B10 life exceeding 50,000 hours under typical conditions. Centralized greasing lines facilitate routine maintenance. | ROI Impact: Decreases planned maintenance time by approximately 30% and extends major service intervals directly lowering labor costs.

Application Scenarios

Granite Quarry Primary Crushing Station

Challenge： A large granite quarry experienced excessive downtime from tramp metal （drill bits， bucket teeth） causing catastrophic damage to the toggle assembly on their existing jaw crusher， averaging three major stoppages per year.
Solution： Implementation of our PJ1200HD primary jaw crusher with a full hydraulic toggle protection system.
Results： In two years of operation， six tramp iron events have been cleared in under two hours total combined downtime with zero component damage， increasing annual available production time by an estimated ~300 hours.

LargeScale Urban Construction Recycling

Challenge： A contractor processing demolished concrete and reinforced asphalt needed high throughput but required protection against uncrushable rebar nests， which caused frequent jams and damaged bearings on their previous crusher.
Solution： Deployment of our primary jaw crusher equipped with hydraulic setting adjustment and automatic release functionality.
Results： The plant now processes over ，500 tons of demolition material per day with predictable output sizing． Uncrushable events are cleared in minutes instead of hours． Bearing temperature monitoring shows stable operation within optimal ranges．
