【Names】:SKJ Series Jaw Crusher
SKJ series European Jaw Crusher is generally suitable for primary and secondary crushing. Adopting the most advanced technology and craftsmanship in the world, SKJ series European Jaw Crusher is the top choice when crushing hard, strong-corrosive materials effectively with unique advantages on structural design, working performance, service life and maintenance. The latest SKJ series European jaw crusher researched and developed by Shanghai Shunky Machinery Co., ltd, which has become the most popular Jaw Crusher in the construction of highway, railway, airport runway, mining, building materials, metallurgy, chemical industries, etc.
The motor drives movable jaw assembly do reciprocating motion according to the desired trajectory under the action of belt and pulley. The angle between toggle plate and movable jaw increases when movable jaw moves up and the movable jaw closes to the fixed jaw. The materials are crushed in this process. The angle between toggle plate and movable jaw decreases when movable jaw moves down and movable jaw moves away from fixed jaw under the action of the tension rod and spring, then products after being crushed are discharged from the discharge opening.
1.More advanced movable jaw assembly lengthens the using life. The movable jaw assembly is composed of high-quality steel casting (weld assembly); large flywheel (pulley) adopts inblock casting process; the heavy eccentric shaft is processed of forging. All of the above processes make SKJ series European Jaw Crusher own overwhelming reliability.
2.Integral cast steel structure is adopted for bearing seat. The integral bearing seat can fit the frame completely, which not only enhances the radial strength but also reduces the maintenance cost.
3.Bearing with larger specification and higher bearing capacity is used. Compared with the other series of jaw crushers, SKJ series European Jaw Crusher adopts larger and more durable bearing. The larger carrying capacity and efficient labyrinth seal lengthen the life span of bearing dramatically.
4.Crusher chamber adopts “V” structure. Symmetric “V” chamber structure design, large angle of toggle plate, large stroke and optimal revolving speed bring larger feeding size, larger capacity, more evenly particle sizes and reduced abrasion of jaw plates.
5.Adjustment of the discharge part is more convenient. The discharge opening is adjusted by hydraulic and wedge block type, which makes discharge opening adjustment more convenient and makes maintenance more automatic. This system can reduce downtime obviously when the chamber needs to be cleared for the machine halt caused by power failure.
6.The more reasonable of design for kinetic parameters of crushing chamber, the more effective stroke at the bottom. The SKJ series adopts more higher centrifugal force and steep inclined angle of toggle plate design. Larger stroke, appropriate speed and flywheel inertia,which ensure better crushing performance.
7.Tooth-type jaw plate is adopted. The adoption of tooth-type jaw plate increases the capacity and lengthens the maintenance period of spare parts.
8.More rational design and more stable performance. The complete machine adopts modular design, which makes disassembly and transportation more convenient. The raised movable jaw plate can not only protect the movable jaw and bearing chamber but also ensure smooth discharging and realize optimal continuous crushing operations.
9.Integrated motor frame. The motor frame and crusher frame of SKJ jaw are installed together , which reduces installation space and length of "V" belt。Because the crusher and the whole motor frame can move synchronously, and we can adjust the tension of "V" type belt by changing the position of the motor frame pivot, the V" type belt can last longer.
10.Special damping device, effectively protect machine. The rubber damping device and limiting block of SKJ Jaw can reduce the impact to crusher foundation by absorbing the load of vibration peak, and extending transverse and longitudinal displacement. The unique installation system avoids the ground bolt damaging jaw crusher foundation .
11.More safety and reliability. The flywheel cover is fixed on the aside plate of SKJ jaw by bolt, which protects the operator, and make the maintenance much easier.
Model Of Jaw
Length Of Feeding Opening(mm/inch)
Width Of Feeding Opening
Closed Size Setting(mm/inch)
The above figures represent through the crusher capacities, which are based on a feed material with an average specific gravity of 2.7t/m3, a maximum feed size that will enter the crusher without bridging and material finer than the crusher’s closed side setting removed. The capacities may vary depending on the feeding method and on feed characteristics such as gradation, bulk density, moisture, clay content and crushability.
Measurement of the crusher’s closed side setting varies depending on the jaw profile that is being used and gradation.The following factors will enhance crusher capacity and performance:
1.Proper feed gradation.
2.Controlled feed rate.
3.Sufficient feeder capacity and width.
4.Dequate crusher discharge area.
5.Discharge conveyor sized to convey maximum crusher capacity.
