CJC-60 Jaw Crusher Machine 60-110 T/H

The CJC-60 represents a robust solution for primary crushing operations across diverse material types. With a jaw opening of 600 x 380 mm, this machine handles everything from softer limestone to extremely hard granite with consistent efficiency. The 60 to 110 tons per hour capacity makes it an ideal choice for medium-scale crushing plants where reliable performance matters most.

At the heart of this crusher lies a 30 kW motor paired with a flywheel operating at 330 rpm. This combination ensures the inertia needed to crush even the most resistant materials without compromising throughput. The large flywheel design maintains crushing momentum during operation, reducing the risk of jamming and keeping production steady throughout the shift. The closed side setting adjusts between 30 and 100 mm, offering flexibility to produce various output sizes depending on project requirements.

The frame construction sets this model apart from standard crushers in its class. Heavy-duty steel undergoes submerged arc welding before thermal stress relief treatment, creating a base structure that withstands years of demanding service. This manufacturing approach eliminates weak points that typically develop under constant vibration and impact loads. The 6,000 kg total weight contributes to operational stability, minimizing movement during crushing cycles and extending component life.

Bearing selection directly impacts crusher reliability. The CJC-60 uses oversized spherical roller bearings with self-aligning capabilities. These bearings accommodate the eccentric motion inherent in jaw crusher operation while distributing loads evenly across bearing surfaces. Drop-forged chrome-nickel steel forms the pitman construction, absorbing severe impact forces that occur when crushing hard rock. This material choice prevents premature failure and reduces maintenance frequency compared to standard steel castings.

The hydraulic setting mechanism simplifies gap adjustment during operation. Operators can modify the crusher's discharge opening without manual shimming or lengthy downtime. This feature proves valuable when switching between different material types or adjusting product specifications mid-production. The hydraulic system also includes overload protection through safety plates and rear blocks, safeguarding internal components when uncrushable objects enter the chamber.

Special jaw geometry enhances crushing efficiency through optimized angles and stroke patterns. The design maximizes material grip while promoting better particle breakage characteristics. This geometry reduces the generation of fines and improves cubical product shape, important factors for concrete aggregate and road base applications. CONSTMACH engineers calculated these angles specifically to balance throughput with product quality across the machine's operating range.

Optional automatic lubrication systems keep critical wear points properly maintained without manual intervention. These systems deliver precise amounts of lubricant at programmed intervals, preventing both under-lubrication and waste. For operations running multiple shifts or in remote locations, automatic lubrication extends service intervals and reduces the skilled labor needed for routine maintenance.

The CJC-60 integrates seamlessly into both stationary and mobile crushing configurations. Its compact footprint and straightforward installation requirements make it adaptable to various site conditions. Whether feeding secondary cone crushers or producing stand-alone products, this jaw crusher delivers the consistent first-stage reduction that downstream equipment depends on for optimal performance.
