Heavy-Duty Jaw Crusher for Medium-Hard Ore and Industrial Mineral Crushing

Product Overview

This jaw crusher is engineered for medium to fine crushing of medium-hard ores and rocks in demanding industrial environments. With a robust design and deep crushing chamber, it ensures high throughput and uniform product size, making it a dependable workhorse for continuous operations. Its advanced geometry eliminates dead zones, maximizing material intake and minimizing bridging, while the optimized nip angle delivers superior reduction ratios.

It is widely used in metallurgy, mining, chemical processing, cement production, construction, refractory materials, and ceramics. The unit handles materials with compressive strength up to 320 MPa, delivering reliable reduction across a wide range of feed materials. From primary crushing of raw ore to final sizing for laboratory analysis, this versatile machine adapts to diverse process requirements.

Built for durability, this system operates with minimal maintenance and low energy consumption, providing consistent performance even under heavy workloads. Its precision-engineered components and safe lubrication system guarantee long service life and operational safety. Additionally, the modular design simplifies wear part replacement, further reducing downtime and operating costs.

Key Features

• Deep Crushing Chamber with No Dead Zones: The geometrically optimized chamber design eliminates dead zones that typically trap material and reduce throughput. This ensures smooth, uninterrupted material flow, maximizing the effective crushing volume and increasing capacity by up to 20% compared to conventional chambers.
• High Reduction Ratio and Uniform Grain Size: The precise nip angle and optimized stroke combine to produce a large reduction ratio while maintaining a tightly controlled product size distribution. This uniformity minimizes oversize recirculation in closed-circuit operations and enhances the quality of downstream products, such as concrete aggregates or mill feed.
• Shim-Type Discharge Adjustment: A robust shim mechanism allows operators to quickly and accurately set the discharge opening within a broad range, from 70 to 160 mm, without complex tools. This flexibility enables on-the-fly adaptation to changing material properties or production targets, improving overall plant utilization.
• Safe and Easy-to-Maintain Lubrication System: A centralized, sealed lubrication system protects all critical bearings from contamination while simplifying routine service. Easy access to lube points and extended grease intervals reduce maintenance labor and ensure consistent lubrication under dusty, high-load conditions.
• Simple and Robust Construction: The all-welded steel frame and high-grade cast steel components are designed to absorb impact forces and resist fatigue. This no-frills design translates to lower initial investment, reduced spare parts inventory, and straightforward maintenance, resulting in the lowest possible total cost of ownership.
• Energy-Efficient Operation: Advanced kinematic analysis enables efficient power utilization, reducing electrical consumption per ton of product by 15%–30%. When integrated into a system with proper feeder and conveyor sizing, overall system energy savings can exceed 50%, contributing to sustainability goals and lower operating costs.
• Versatile Discharge Range: The ability to adjust the discharge opening over a wide span allows this single machine to serve multiple crushing stages—from coarse secondary crushing at 160 mm down to fine tertiary crushing at 70 mm—reducing the need for additional equipment in multi-stage circuits.
• Low Noise and Dust Emission: Careful attention to clearance fits and vibration-damping mounts minimizes operating noise, while sealed joints and optional dust collection connections keep airborne particles within permissible limits. This improves operator comfort and helps meet stringent occupational health and environmental regulations.

Why Choose This Product

• Proven Reliability in Harsh Environments: Constructed with heavy-duty, high-tensile steel plates and precision-machined components, this crusher has demonstrated decades of dependable service in arid deserts, humid tropics, and freezing high-altitude mines. Its robust design withstands shock loads from tramp iron and relentless 24/7 cycles without structural fatigue.
• Precision Manufacturing for Consistent Output: Advanced CNC machining and rigorous quality control ensure tight jaw alignment and uniform crushing surfaces. This precision directly translates to a highly consistent product size distribution, reducing recirculation loads in closed circuits and eliminating production bottlenecks.
• Superior Build Quality: Key wear parts are made from high-manganese steel, work-hardened in service to extend life. Critical bearing housings are sealed with labyrinth and grease purging to exclude dust, while the frame is stress-relieved after welding to ensure dimensional stability over the machine’s lifetime.
• Customizable to Your Needs: Beyond the standard configuration, options include different jaw plate profiles (corrugated, flat, or toothed) for specific material characteristics, hydraulic or manual adjustment assist, and integrated PLC-based condition monitoring. This adaptability allows the crusher to be optimized for your unique process.
• Global Support and Service: Our dedicated support network spans six continents, providing rapid-response field service, remote diagnostics, and localized spare parts inventories. From installation and commissioning to lifecycle optimization, we partner with you to maximize uptime.
