CJC-110 Jaw Crusher Machine 150-420 T/H

The CJC-110 represents a fundamental solution for operations requiring robust primary crushing capabilities. With a jaw opening of 1,100 x 850 mm and production capacity ranging from 150 to 420 tons per hour, this machine handles the initial breakdown of materials spanning the entire hardness spectrum. Whether processing soft limestone or the most resistant granite, the CJC-110 maintains consistent performance through its engineered design principles.

At the core of this crusher's reliability lies its heavy-duty construction approach. The base frame undergoes submerged arc welding followed by thermal stress relief, creating a foundation that withstands continuous operational demands. This manufacturing process eliminates internal stresses that typically lead to premature frame failure in crushing equipment. The frame supports oversized spherical roller bearings with self-aligning properties, ensuring the crushing mechanism maintains proper alignment even under extreme loads. These bearings absorb radial and axial forces while compensating for minor misalignments that occur during operation.

The pitman assembly deserves particular attention for its material engineering. Drop-forged chrome-nickel steel provides the strength necessary to handle impact loads from large feed materials. This forging process creates a grain structure that resists crack propagation, extending component life significantly beyond cast alternatives. When crushing demands exceed expectations, the pitman absorbs and distributes forces without catastrophic failure, protecting downstream components and maintaining operational continuity.

Power delivery comes from a 132 kW motor driving flywheels at 230 rpm. The large flywheel diameter stores kinetic energy throughout the crushing cycle, maintaining momentum when the jaw encounters particularly hard material. This energy storage prevents motor stalling and creates a more consistent crushing action. The relatively moderate flywheel speed balances crushing force with throughput, optimizing the trade-off between reduction ratio and production capacity.

Operational flexibility comes through the hydraulic setting mechanism, which adjusts the closed side setting between 60 and 200 mm. This range accommodates varying product size requirements without mechanical disassembly. Operators modify the jaw gap while monitoring production output, fine-tuning the setting to match material characteristics and downstream processing needs. The hydraulic system responds quickly to adjustment commands, minimizing downtime during product changeovers.

For facilities with demanding operational schedules, the CJC-110 can be equipped with automatic lubrication systems. These systems eliminate manual greasing intervals, ensuring bearing and bushing surfaces receive proper lubrication regardless of shift patterns. Consistent lubrication reduces friction-related wear and prevents the thermal damage that occurs when critical surfaces run dry.

The machine's 33,000 kg operating weight provides the mass necessary for stable crushing action. This substantial weight anchors the crusher during operation, preventing movement that would otherwise reduce crushing efficiency and accelerate wear on mounting points. The geometry of the crushing chamber, combined with carefully calculated jaw angles, creates an efficient nip point that captures feed material and progressively reduces particle size as material descends through the chamber.

CONSTMACH jaw crushers integrate into both stationary and mobile crushing configurations, serving as the primary reduction stage. This versatility allows operations to deploy the same crushing technology across different site layouts and production requirements. The CJC-110 delivers the consistent performance that downstream screening and secondary crushing equipment depend upon, establishing the foundation for complete aggregate production systems.
