Overview of Pascal Jaw Crushers JC Series
The JC Series Jaw Crusher, distributed by Luoyang Pascal, is a high-performance primary crushing solution that integrates international advanced technology to outperform traditional PE series models. It is characterized by its "V" shaped crushing cavity, which increases feeding size and throughput by up to 30%.
Features of Pascal Jaw Crushers JC Series
The JC Series is engineered for processing hard and abrasive rocks in mining, construction, and metallurgy. Key features include:
Robust Frame Structure: Available in welded models for small/medium sizes and modular, non-welded "packaged" designs for large models to simplify transport to remote or underground sites.
Optimized V-Cavity: Symmetrical design with a large inclination toggle plate and long stroke for higher productivity and better gradation.
Efficient Adjustment: Uses mechanical or hydraulic wedge devices for infinite Closed Side Setting (CSS) adjustment, significantly reducing downtime compared to traditional shim methods.
Integrated Motor Design: The motor base is integrated with the main frame, saving installation space and extending V-belt life.
Techspecs of Pascal Jaw Crushers JC Series
The JC series spans a wide range of capacities and sizes to fit various industrial needs.
Work Principles of Pascal Jaw Crushers JC Series
The JC Series operates on a single-toggle compression principle. An electric motor drives a belt and pulley system, causing an eccentric shaft to move the swing jaw in a specific elliptical track. Material entering the V-shaped chamber is crushed between a fixed and moving jaw plate through impacting and striking until it is small enough to discharge through the bottom opening.
Applications of Pascal Jaw Crushers JC Series
Primary Industry Applications
Mining and Quarrying: Acts as the first-stage (primary) reduction machine for extracted ores including iron, gold, copper, and manganese. It is also widely used in quarries for producing stone blocks and aggregates from granite and limestone.
Infrastructure and Construction: Essential for building highways, railroads, and water conservancy projects by crushing raw stone into the base materials needed for road foundations and structural concrete.
Recycling and Demolition: Mobile versions of the JC series are frequently used on-site to process reinforced concrete, asphalt, and demolition debris, transforming waste into reusable backfill or road base.
Industrial Manufacturing: Used in the production of cement, chemicals, ceramics, and fireproof materials to crush raw mineral stones and slag with compressive strength up to 320 MPa.
Material Compatibility
The JC Series is engineered to handle a broad range of high-hardness raw materials:
Hard Rocks: Granite, basalt, diabase, quartz, and river stone.
Metallic Ores: Iron ore, copper ore, gold ore, and manganese ore.
Other Materials: Limestone, gravel, marble, pebbles, and industrial slag.
Specialized Use Cases
Underground and High-Altitude Mining: Modular, non-welded frame designs allow the crusher to be sectionalized for easier transport into narrow underground spaces or remote, high-altitude locations where traditional oversized frames cannot reach.
Mobile Operations: Specific models (marked with an asterisk in technical specs, like the JC96 or JC106) are optimized for mobile crushing stations, allowing for flexible on-site processing that reduces transportation costs.
Customization of Pascal Jaw Crushers JC Series
Luoyang Pascal JC SeriesJaw Crusher allows operators to adapt the machine to specific geological conditions, installation environments, and production targets. Pascal offers "Customized Service" where small, medium, and large models can be tailored to meet unique customer needs.
Structural & Installation Customization
Modular Frame Design: For large-scale models, Pascal provides non-welded, modular bolt-connected frames. This customization is specifically designed for transport into narrow spaces, such as underground mines or remote high-altitude sites, where a standard one-piece welded frame would be impossible to deliver.
Integrated Motor Base: The motor chassis can be integrated directly with the crusher frame, saving significant installation space and allowing the motor to move synchronously with the crusher to reduce V-belt wear.
Shock Absorber Systems: Special rubber shock absorbers can be customized for the base to effectively absorb peak vibrations, protecting the foundation and allowing for flexible displacement in both vertical and horizontal directions.
Performance & Wear Customization
Jaw Plate Profiles: To optimize performance for different materials (e.g., granite vs. limestone), various tooth shapes and profiles are available. These custom profiles can adjust the effective crushing area and the final product gradation.
Alloy Selection: Wear parts like fixed and movable jaw plates can be customized using different grades of high-manganese steel or proprietary alloys to balance impact resistance with abrasion protection based on the material's hardness.
Adjustment Mechanisms: Customers can choose between mechanical or hydraulic double-wedge adjustment systems for setting the discharge opening (CSS). The hydraulic option allows for faster, "infinite" variable adjustments that minimize operational downtime.
Optional Technical Enhancements
Monitoring Systems: Advanced units can be customized with optional temperature sensors, rotation speed sensors, and material level detection systems within the crushing chamber to automate feed control and prevent overloads.
Lubrication Upgrades: While grease lubrication is standard, a circulating oil lubrication system with an external reservoir and low-oil alarm is available for heavy-duty or continuous-duty models like the JC5460.
Environmental Kits: For specific climates or regulations, machines can be equipped with dust suppression water sprays, particulate filters for diesel engines, or specialized treatments for extremely cold conditions.
Parts of Pascal Jaw Crushers JC Series
Key wear and structural components include:
Manganese Jaw Plates: Reversible top-to-bottom for extended wear life.
Bearings: Oversized, self-aligning spherical roller bearings for smooth, low-friction operation.
Eccentric Shaft: Forged heavy-duty chrome-moly-nickel steel designed for high fatigue resistance.
Toggle System: Includes the toggle plate and seat, often designed for easy replacement or with hydraulic overload protection.
Packaging and Shipping of Pascal Jaw Crushers JC Series
For shipping, JC Series crushers are often sectionalized or built with modular bolted frames to facilitate transportation to narrow or high-altitude locations. Heavy-duty components like the main frame and flywheels are typically secured on reinforced pallets or flat racks to handle the extreme weight during international logistics.
