The high quality of the Christon CJ Series Jaw Crushers stems from their meticulous design and manufacturing materials, where even the slightest details are perfected to ensure both functionality and reliability. Employing a modular, weld-free frame structure, the two hot-rolled steel side plates are securely bolted to a high-quality cast steel frame through precision-machined pins, eliminating stress concentration points (such as welds) that could compromise equipment durability under impact loads.
The enduringly robust jaw assembly is constructed from high-quality cast steel components and driven by two large cast steel or cast iron flywheels. Furthermore, the forged heavy-duty eccentric shaft and four equally sized large spherical roller bearings contribute to the exceptional reliability of the CJ Series Jaw Crushers. A labyrinth seal protects the bearings' lubricating grease from contamination.
The integral cast steel bearing housing ensures a precise fit with the crusher frame while avoiding unnecessary loads on the bearing housing, which are inevitable in split-type bearing housing structures.
Repairable Crusher Frame:
The CJ Series Jaw Crushers are designed to meet the demands of round-the-clock continuous operation within their service life, but some maintenance is still required. Thanks to the use of cast steel components, the crushers can be economically repaired or refurbished even after years of operation. In contrast, similar repairs on crushers with other frame structures can be costly or even impossible.
Performance Advantages of CJ Jaw Crushers:
The performance of CJ Jaw Crushers is based on their wide feed opening, small nip angle, and large eccentric throw.
Well-Designed ChamberThe high-performance crushing chamber, the heart and working area of the jaw crusher, is designed with a "from-the-inside-out" approach. This reflects Christon's long-standing focus on the feed opening size and chamber height of jaw crushers. An appropriate feed opening aspect ratio minimizes material blockage and reduces the crusher's height.
Excellent Kinematics and Powerful DynamicsGood crushing performance also relies on optimal kinematic parameters. The CJ Series Jaw Crushers feature high centrifugal force and a steep toggle plate inclination, resulting in a larger effective stroke at the bottom of the crushing chamber. The combination of large stroke, suitable rotational speed, flywheel inertia, and high crushing utilization energy ensures superior crushing performance. When operating with a small discharge opening, the CJ Series Jaw Crushers can produce finer crushed products than other jaw crushers.
Customized Jaw Plates for Specific ApplicationsTo maximize the performance of the CJ Series Jaw Crushers across various applications, including traditional quarrying, mining, gravel, and recycling of waste materials and asphalt, Christon has developed a range of jaw plates. The jaw plate tooth profiles and thicknesses are continuously optimized, and appropriate manganese steel alloy materials are selected to enhance productivity while reducing operating costs. Christon is also active in developing customized jaw plates and cheek plates for special purposes.
