Crush silica jaw crusher is a new type of jaw crusher which CFTC Company introduced on the basis of introducing advanced European jaw crusher technology. It is the preferred equipment for rough crushing various rocks.

Crush silica jaw crusher features:

Solid structure
The rack is divided into two types: welded type and assembled type: small and medium-sized specifications are generally welded, and large-size specifications are generally assembled. The welding type adopts large arc transition fillet and low stress zone welding method, which greatly reduces the stress concentration, ensures the uniformity of the frame in all directions, and has the characteristics of impact resistance, uniform force and low failure rate. The assembled type adopts advanced modular and welded frame structure design, with high fatigue strength and high reliability. At the same time, the whole machine is assembled and designed, which is more convenient for transportation and installation. It is especially suitable for underground mines, high-altitude mines and other small and difficult transportation places. installation.
2. Superior cavity design
Symmetrical "V" shaped cavity design, large inclination of the bracket, large stroke, reasonable speed, making the feed size larger, the output higher, the particle size more uniform, and the wear of the jaw is reduced.
3. Heavy-duty moving jaw assembly is durable
The heavy-duty dynamic boring assembly adopts forged heavy-duty eccentric shaft, high-quality heavy-duty rolling bearing and finite element software optimized dynamic boring body to ensure high impact resistance and stability of the dynamic boring assembly; labyrinth seal and centralized lubrication system ensure Bearing grease is not polluted and lubricated more easily, making it run longer and more stable.
4. Dynamic guard plate design
Heavy-duty guards are installed above the moving raft to avoid material damage and effectively protect the moving body and its internal bearings from damage.
5.Integral bearing housing
The overall cast steel bearing housing structure ensures complete cooperation with the frame, avoiding the unnecessary radial load on the bearing during the fastening process of the combined bearing seat, and making the bearing run more smoothly.
6. Convenient and fast particle size adjustment
The JC series jaw crusher adopts mechanical or hydraulic discharge port adjustment device, and the double wedge adjustment mode is simpler, safer and faster than the gasket adjustment operation, which saves downtime.
7. Integrated motor installation
The integrated installation of the motor base and the crusher frame not only saves the installation space of the jaw crusher, reduces the length of the V-belt, but also realizes the synchronous movement of the frame, the motor base and the motor, and the adjustable motor base. The adjustment of the tension of the V-belt makes the V-belt last longer.
8. Shock absorption installation design
The crusher is fixed by a special rubber damping device, which effectively absorbs the vibration peak of the equipment and allows the vertical and longitudinal displacement of the crusher, thus reducing the impact on the foundation.

Taking the traditional jaw crusher as an example, as a kind of curved crushing crushing equipment, when the E-breaking machine works, the electric motor drives the belt and the pulley, and moves the movable jaw up and down through the eccentric shaft, and when the moving jaw rises, the bracket is The angle between the moving jaws becomes larger, so that the moving jaw is approached to the fixed jaw, and at the same time the material is crushed or crushed to achieve the purpose of breaking; when the moving down, the angle between the bracket and the moving jaw becomes smaller. Under the action of the pull rod and the spring, the movable jaw leaves the fixed jaw, and the broken material is discharged from the lower mouth of the crushing chamber. As the motor rotates continuously, the crushing maneuvering cycle motion crushes and excretes the material to achieve mass production.
