CJC-140 Concasseur à Mâchoires 420-850 T/H

The CJC-140 represents a significant advancement in primary crushing technology, engineered specifically for operations demanding both power and precision. With a jaw opening of 1,400 x 1,100 mm, this machine tackles everything from soft limestone to the most challenging granite formations. The 200 kW motor delivers consistent performance across varying material hardness levels, while the 220 rpm flywheel speed maintains the momentum needed to process even the toughest aggregates without hesitation.

What sets the CJC-140 apart is its intelligent design approach. The heavy-duty base frame undergoes a specialized manufacturing process—submerged arc welding followed by thermal stress relief treatment. This isn't just about meeting standards; it's about exceeding operational expectations in real-world quarry conditions. The oversized spherical roller bearings feature self-aligning capabilities, which means less downtime for adjustments and more time crushing material. These bearings handle radial and thrust loads simultaneously, distributing stress evenly across the mechanism.

The pitman construction deserves particular attention. Drop-forged from chrome-nickel steel, it absorbs impact forces that would compromise lesser machines. This material choice directly translates to longer service life and reduced maintenance intervals. The hydraulic setting mechanism allows operators to adjust the CSS (closed side setting) anywhere between 120 and 280 mm, adapting quickly to different product specifications without manual intervention. This flexibility proves invaluable when switching between applications or responding to changing market demands.

Production capacity ranges from 420 to 850 tons per hour, positioning the CJC-140 as a workhorse for medium to large-scale operations. The substantial flywheel design stores kinetic energy, releasing it precisely when needed to crush oversized material. This creates a smoother crushing action and reduces peak power demands on the motor. For operations requiring continuous lubrication, the machine accommodates automatic systems, minimizing manual maintenance tasks and extending component life.

CONSTMACH jaw crushers function as the foundation of both stationary and mobile crushing plants. The special geometry of the jaw angles maximizes crushing efficiency while minimizing wear. Safety plates and rear blocks provide protection during operations, and the user-friendly controls make adjustments straightforward even for less experienced operators. At 52,000 kg, the CJC-140 maintains stability under heavy feed conditions, reducing vibration transfer to surrounding structures.

This crusher handles the critical first stage where material reduction begins. Getting this step right affects everything downstream—secondary crushing, screening efficiency, and final product quality. The CJC-140 delivers consistent output, creating a solid foundation for the entire crushing circuit. Its robust construction and thoughtful engineering details reflect decades of industry knowledge applied to modern crushing challenges.
