CJ Jaw Crusher

What is CJ Jaw Crusher?

CJ series jaw crusher is a jaw crusher with more excellent performance launched and developed by ChunLei Machinery according to the market demand of customers. Unlike PE jaw crusher, it has significant improvements in crusher movement parameters, structural forms, adjustment methods, etc. The CJ series jaw crusher covers a smaller area and has a better crushing ratio than PE jaw crusher.

CJ series jaw crusher has a smaller footprint, larger crushing ratio and more stable operation. It adopts deep V-shape cavity crushing, which has no dead angle during crushing, and improves the feeding capacity and crushing efficiency. It is especially suitable for mobile crushing plant.

What Is Jaw Crusher Used For?

Jaw crusher is widely used in various industries such as metallurgical mines, mining, highway and railroad construction, building construction, water conservancy and chemical industry. In the production of mineral processing industry, they are generally used for coarse and medium crushing of hard or medium-hard ores.

Whether it is hard rock crushing, river pebble crushing, concrete recycling or aggregate processing, it must be equipped with high quality jaw crusher. The processed finished products have uniform particle size and high sales volume of finished products, which can meet the high standard requirements of materials in the construction field.

Applied Materials: Pebble, calcite, granite, quartz, concrete, dolomite, bluestone, iron ore, limestone, coal gangue, construction waste, ferrosilicon, basalt, sandstone, cement clinker and so on.

Working Principle of CJ European Jaw Crusher

The Jaw Crusher consists of two jaw plates, the movable jaw and the static jaw, which mimic the movement of an animal’s lower jaw to accomplish the material crushing operation. The moving jaws reciprocate relative to the static jaws, and the material fed from the top chamber is compressed between the two jaw plates and crushed into small pieces.

Advantageous features of CJ European Jaw Crusher for sale

• Strong feeding capacity: Deep” V” type crushing cavity, the optimized configuration of crushing cavity structure and movable jaw trajectory parameters, large stroke to maximize the feed size, output and crushing ratio.
• High strength steel elbow plate: Light weight, easy to replace, bending when overloaded, avoiding the traditional cast iron elbow plate to hurt the conveyor belt when it breaks and falls.
• Easy adjustment: Adopting wedge adjustment instead of traditional pad type discharge opening adjustment, which makes the adjustment of discharge opening easier to realize stepless adjustment.
• Improve service life: Adopting elastic limit block and rubber shock absorbing device instead of the original rigid foot connection improves the performance of the dynamic balance system of the whole machine and improves the service life of the equipment.

• Convenient transportation:The integrated motor base design reduces the installation space of the equipment and makes the power output more stable.

FAQ

Q: What is the maximum feed size for a CJ European jaw crusher?
A: The maximum feed size depends on the specific model, but typically ranges from 500mm to 1200mm. For example, the CJ411 model can handle up to 660mm, while larger models like CJ612 accept up to 1000mm.

Q: What is the difference between CJ European jaw crusher and traditional jaw crushers?
A: The CJ series uses a deep, symmetrical crushing chamber and a larger stroke for higher capacity and better reduction ratio. It also features a welded and heat-treated frame for higher strength and reliability, while traditional jaw crushers often have cast frames and shorter strokes.

Q: What kind of materials can a CJ jaw crusher process?
A: It can process hard and abrasive materials such as granite, basalt, iron ore, limestone, quartz, river gravel, and concrete rubble. It is ideal for primary crushing in mining, quarrying, recycling, and construction applications.

Q: How do I choose the right CJ European jaw crusher model for my plant?
A: Consider your required feed size (max 500-1200mm), desired output capacity (50-1500 tons per hour), and finished product size. Smaller sites often choose CJ411 or CJ412, while large mines need CJ612 or CJ615. Our engineers can recommend the best model based on your material hardness and production goals.

Q: What is the maintenance schedule for a CJ jaw crusher?
A: Daily checks include lubrication levels, wear liner condition, and bolt tightness. Jaw plates typically last 3-12 months depending on material abrasiveness. Bearings require grease replacement every 500-1000 hours. The crusher is designed with easy-access maintenance platforms and hydraulic toggle adjustment to reduce downtime.

Q: Does the CJ European jaw crusher come with a hydraulic adjustment system?
A: Yes, most CJ series models feature a hydraulic wedge adjustment system for closed side setting (CSS). This allows operators to change the output size quickly and safely without manual shims, saving hours of downtime.

Q: What is the typical power consumption of a CJ jaw crusher?
A: Power ranges from 90kW to 400kW depending on the model. For example, CJ411 uses 132kW while CJ615 uses 315kW. The energy efficiency is higher than older jaw crusher designs due to optimized kinematics and lighter weight flywheels.

Q: Can the CJ European jaw crusher be used in mobile crushing plants?
A: Yes, many OEMs integrate CJ series crushers into mobile track-mounted or wheeled plants. The compact design and robust construction make them suitable for portable applications in quarrying and recycling.

Q: What spare parts should I keep in stock for my CJ jaw crusher?
A: We recommend keeping stationary and moving jaw plates, side liners, toggle plate, toggle seats, and main bearings. For critical operations, also stock hydraulic hoses and oil seals. We offer wear parts with extended service life options.

Q: How long does delivery and installation take for a CJ European jaw crusher?
A: Standard models are typically delivered within 30-45 days after payment. Installation takes 7-14 days including foundation work, assembly, and commissioning. We also provide remote or on-site technical support for installation.
