Henan Dewo Machinery Co., Ltd. is the leading enterprise of rock & mineral processing equipment in the world. Since the end of the 20th century, we've installed more than 10,000 crushing plants all over the world. Nowadays, European type jaw crusher has already become the most popular equipment in the world without controversy. It is the first choice for hard and strong abrasion material.

Principle

The electromotor drives the belt and pulley to make the movable jaw move back and forth, up and down through the eccentric shaft. The raw material is squashed or split when movable jaw plate moves towards fixed jaw together with movable jaw. When movable jaw and movable jaw plate turning back by eccentric shaft and spring, the raw material, which is squashed or split before discharges from the bottom outlet under jaw plate. The bulk-production comes true while electromotor rotates continuously and the movable jaw crushes and discharges the raw material periodically.

Features

1. Sturdy Structure
Two kinds of Frames: Welded and Packaged. Usually, Small and medium sized model adopts welded, large model adopts 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 transporting and installation, especially suitable for installation of underground mine shaft, high altitude mine, as well as other narrow and difficult transporting 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 bearings 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. Therefore the assembly can have a long working time and stability.

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 crusher, thus reducing the impact on the foundation.
