Hard Stone Primary Jaw Crusher For Granite/Quartz Stone Crushing Plant:
1 Jaw Crusher Application: jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. It is widely applied to crush high hardness, mid hardness and soft rocks and ores such as slag, construction materials, marble, etc. The pressure resistance strength is under 200Mpa, that is, suitable for primary crush. Jaw crusher can be used in mining, metallurgical industry, construction, road and railway building, conversancy, chemistry, etc
2.Jaw crusher structure :
The jaw crusher is made up of frame, flywheel, movable plate, fixed plate, toggle plate, set adjustment, main bearing, etc. The toggle plate is used for protection.
3. Jaw Crusher Features
1. It adopts world-level manufacturing technology and high-end manufacturing materials.
2. More advanced movable jaw assembly makes it more durable. The movable jaw assembly uses high-quality steel casting and drives through two large-sized cast steel flywheels. In addition, the heavy eccentric shaft also adopts forging stock which makes JC series jaw crusher have extraordinary reliability.
3. The bearing pedestal adopts unitary cast steel structure. The unitary cast steel bearing pedestal can ensure comprehensive fitting with the crusher rack, and at the same time, greatly increase the radial strength of the bearing pedestal, whereas split type bearing pedestal does not have these advantages.
4. By using finite element analysis technology, the jaw crusher has higher strength.
5. The crushing chamber adopts symmetrical V-shaped structure, so that the actual width of the feeding mouth is in line with the nominal width of the feeding mouth.
6. The adjustment of the discharging mouth is quicker and more convenient. European type JC series jaw crusher is equipped with wedge discharging mouth adjustment device, so that the adjustment of the discharging mouth is simpler, safer and quicker than that of traditional gasket adjustment.
7. The selected bearing has bigger specifications and higher carrying capacity. All the JC series jaw crushers are equipped with eccentric shaft bearing bigger and more durable than the crushers with the same specifications, and the higher carrying capacity and effective labyrinth sealing of this bearing greatly extends its service life.
8. It adopts the latest tooth back plate which increases the effective length of the jaw plate and the output of jaw crusher.
4. Main spare parts-jaw plates:
If you have a jaw crusher that is in need of maintenance and new parts, we can help. We can supply, install and send our jaw crusher parts to anywhere in the world. We carry a full line of wear parts for your jaw crushers and if you have a part that is no longer made by the manufacturer, we can fabricate for you. We have many case histories in which wear life can be increased by 50%, and some can even be increased up to 100%.
5.jaw crusher working principle:
The dynamic jaw moving from side to side is hung on the mandrel. When the eccentric shaft is turning, its connecting rod moves up and down, which also drives the two thrust plates to do the same movement. Then the dynamic jaw moves from side to side to realize crushing and unloading. The jaw crusher adopts crank link mechanism. Although the dynamic jaw bears great broken counter-force and the eccentric shaft and the connecting rod bears little stress, industrial enterprises usually make large sized machine and middle sized to crush hard materials. Additionally, every moving track of the dynamic jaw is an arc with the mandrel as its center. The circular arc radius equals the distance from the point to the axis with the upper arc being smaller and the lower arc bigger. The crushing efficiency of the jaw crusher is quite low and the crushing ratio is 3-6.
