CJC-130 Jaw Crusher Machine 275-790 T/H

The CJC-130 model represents CONSTMACH's commitment to delivering robust primary crushing solutions for the most demanding quarrying and mining operations. With a jaw opening of 1,300 x 1,000 mm and a production capacity ranging from 275 to 790 tons per hour, this crusher is engineered to process everything from soft limestone to exceptionally hard granite. The machine serves as the backbone of both stationary and mobile crushing plants, providing reliable performance where initial material reduction is critical.

At the heart of the CJC-130 lies a 160 kW motor that drives the crushing mechanism with precision. Operating at a flywheel speed of 220 rpm, the unit maintains consistent momentum even when confronting challenging materials. The closed side setting (CSS) can be adjusted between 100 and 280 mm, allowing operators to fine-tune the output according to specific project requirements. This hydraulic adjustment system eliminates manual intervention and enables quick modifications without production interruptions. The flexibility in gap settings directly influences particle size distribution, making the CJC-130 adaptable to various applications.

The structural integrity of this jaw crusher comes from its heavy-duty base frame, which undergoes submerged arc welding followed by thermal stress relief treatment. This manufacturing process ensures the frame can withstand extreme operational stresses without deformation. The pitman, forged from chrome-nickel steel, absorbs tremendous crushing forces while maintaining dimensional stability. Oversized spherical roller bearings with self-aligning capabilities accommodate shaft misalignment and reduce maintenance frequency. These bearings handle both radial and axial loads, extending service life significantly.

Weighing 42,500 kg, the CJC-130 offers exceptional stability during operation. The substantial mass, combined with large flywheels, creates the inertia needed to pulverize even the most resistant rock formations. This design philosophy prevents stalling when the crusher encounters uncrushable materials, protecting both the machine and upstream equipment. Safety plates positioned strategically within the crushing chamber provide additional protection against excessive force, while rear blocks maintain proper jaw alignment throughout the crushing cycle.

The jaw angle geometry has been optimized through extensive field testing to maximize throughput without compromising product quality. This special configuration promotes efficient material flow through the crushing chamber, reducing the tendency for material bridging. When paired with the hydraulic setting mechanism, operators achieve precise control over the final product gradation. For operations requiring minimal downtime, CONSTMACH offers automatic lubrication systems that ensure critical wear components receive consistent lubrication without manual intervention.

CONSTMACH jaw crushers are built for operators who demand reliability in environments where equipment failure means lost revenue. The CJC-130 delivers consistent performance across diverse material types, making it suitable for aggregate production, mining operations, and recycling applications. The combination of proven engineering principles and modern manufacturing techniques results in a crusher that performs year after year with minimal intervention.
