    The SKJ European version of the jaw crusher is used for rough and medium crushing operations. The machine integrates crushing technology and manufacturing process, and has superiority in structural design, work performance, service life and maintenance. It is a hard and strong corrosive material for high-efficiency crushing. At present, the European version of SKJ jaw crusher developed and produced by Shanghai Shanqi has become a popular jaw crusher in the fields of expressway, railway, airport runway, mining, building materials, metallurgy and chemical industry.

    SKJ European version jaw crusher works:
    The motor drives the moving jaw assembly to reciprocate according to a predetermined trajectory through the belt and the pulley. When the moving jaw rises, the angle between the bracket and the moving jaw becomes larger, thereby pushing the moving jaw to approach the fixed jaw, and at the same time the material is crushed, crushed and the like is broken. When the moving down, the angle between the bracket and the moving jaw becomes smaller, the moving jaw leaves the fixed plate under the action of the pull rod and the spring, and the broken material is discharged from the discharge opening.

    Performance characteristics:
    1. Dynamic assembly to make it more durable. The movable jaw assembly is composed of high-quality steel castings (welded parts). The large flywheel (pulley) is made of integral casting steel, and the heavy-duty eccentric shaft is forged, which makes the SKJ series jaw crusher highly reliable.
    2. Integral cast steel structure bearing housing. The integral cast steel housing can be fully matched to the frame, while also greatly enhancing the radial strength of the housing and reducing the maintenance cost of the equipment.
    3. The bearing specifications are larger and the bearing capacity is stronger. The SKJ series jaw crusher uses larger and more durable bearings than the same size crusher. Its higher load carrying capacity and effective labyrinth seal design significantly extend bearing life.
    4. Symmetrical “V” type crushing chamber. The symmetrical cavity design, the large inclination of the bracket, the large stroke, and the reasonable rotation speed make the feed particle size larger, the output is higher, the particle size is more uniform, and the wear of the raft is reduced.
    5. Safe and fast discharge opening adjustment device. The hydraulic wedge type discharge opening adjustment device is convenient for adjusting the size of the discharge opening and improving the automation degree of maintenance. The system is easy to operate and reduces downtime when the power interruption causes the equipment to be shut down with load and requires clearing.
    6. More reasonable kinetic parameter design, the effective stroke at the bottom of the crushing chamber is larger. The SKJ series is designed with large centrifugal force and steep bracket tilt angle. The large stroke, suitable speed and flywheel inertia ensure better crushing performance.
    7. Use a toothed guard. The SKJ series of European jaw crushers use a new toothed guard to increase production and extend the maintenance period of consumables.
    8. The structural design is more reasonable and the performance is more stable. The whole machine adopts modular design, which is convenient for disassembly and transportation. The high movable jaw plate can not only effectively protect the moving jaw and the bearing chamber, but also ensure the unloading of the material, avoid the phenomenon of stuffing, and achieve continuous crushing performance.
    9. Integrated motor base. The motor frame of the SKJ series jaw crusher is integrated with the frame of the crusher, reducing the installation space of the crusher and the length of the “V” belt. The “V” belt has a long service life due to the synchronous movement of the crusher and the integral motor base and the position of the pivot on the motor base to adjust the tension of the motor “V” belt.
    10. Special vibration damping device to effectively protect equipment. The rubber damping device and the limit block of the SKJ series jaw crusher effectively reduce the impact of the crusher on the foundation by absorbing the peak load of the vibration and allowing the lateral and longitudinal displacement of the crusher. Install the system to avoid damage to the foundation of the jaw crusher by the anchor bolts.
    11. High safety and reliability. The flywheel shroud of the SKJ series jaw crusher is bolted to the side plate of the crusher, which effectively protects the crusher operator and is easy to maintain.
