JC Jaw Crushers - the Updated Version of PE Jaw Crushers

As a professional manufacturer in the field of crushing and screening, Zhengzhou Yifan Machinery Co., Ltd produces first-rate jaw crusher, which has been outstanding product and wins us great honor. A lot of practice has proved that the device has very strong versatility and good performance in each area, fully meeting the diverse needs of the market. However, the engineer of Yifan pursues the spirit of “There is no best only better” and developed the best-ever jaw crusher -JC series jaw crushers, which is the updated version of PE series.
 
JC series jaw crushers has the characteristics of high efficiency and low cost, it can crush materials of high hardness and high abrasiveness. And JC series jaw crusher is with the most advanced international crushing technology and manufacturing standards. Following are the advantages of the new JC series.

jaw crusher

 
1. Sturdy Structure
 
Two kinds of frames: Welded and Packaged. Usually, small and medium sized model adopts welded, large model adopt packaged. Welded frame adopts wide transitional round edge, significantly reducing the stress concentration; ensure the frame under equal strength. It owns the features of good impact resistance and low failure rate, bears same pressure, etc.
 
Packaged frame uses advanced modularization, no-welding frame structure design, high endurance strength and reliability. The whole set assembling design is convenient for the transportation and installation, especially suitable for installation of underground mine shaft, high altitude mine, as well as other narrow and difficult transportation place.
 
2. Extraordinary Cavity Design
 
Symmetrical V-shaped cavity design, high inclination-angle of the toggle, big stroke and reasonable speed, allows a bigger feeding size, higher capacity, uniform particle size and lower wearing of the plate.
 
3. Long Working Life of the Heavy-duty Movable Jaw Assembly
 
Heavy-duty Movable Jaw Assembly adopts heavy-duty eccentric shaft, high quality heavy-load rolling bearing and finite element software optimized movable jaw plate ensuring impact resistance and high stability of moving jaw assembly; labyrinth seal and centralized lubrication system guarantee the bearing lubrication oil is not contaminated and lubrication becomes more convenient.
 
4. Shield Design for the Movable Jaw
 
Heavy shield is installed above the movable jaw to avoid the material impact. It can effectively protect the movable jaw and its internal bearing from damaging.
 
5. Overall Bearing Support
 
Overall cast steel bearing support fully compatible with the rack, avoiding the combined bearing support has a unnecessary radical load on the bearing during the fastening process, making the bearing to run more smoothly.
 
6. Convenient Particle Size Adjustment
 
JC series jaw crusher adopts mechanical or hydraulic adjustment for the discharge range, compared with shim adjustment, double wedge adjustment operations is simpler, secure, fast, and saves more downtime.
 
7. Integrated Motor Installation
 
Integrated installation of motor seat and frame can not only save installation space, reduce the length of v-belt, but also can prolong v-belt working time, since the frame, motor seat, synchronous move of motor, adjustable motor seat bring v-belt tension adjustment.
 
8. Vibration Absorption Design
 
Crusher fixed by rubber vibration absorption device, which can effectively absorb vibration peak, while allow the vertical and longitudinal displacement of the jaw crusher, thus reducing the impact on the foundation.
