High Effciency Basalt Jaw Crusher

Jaw crusher is often used for coarse, medium crushing. It belongs to the high-end products of jaw crushers. The jaw crusher has its particular advantages in structural design, working performances, service life and failure rate.therefore, it is the first choice for efficient crushing to high hardness and viscosity materials.at present, china is already one of the crusher manufacture powers. Because the customs of good policy, jaw crusher into the coastal strip has become an inevitable trend. Jaw crusher is important crushing equipment for a long time. Jaw crusher is relatively easy to operate and inexpensive with simple structure favored by customers. Its development process is also well documented.
1. The transmission
eccentric shaft is the spindle of high effciency basalt jaw crusherreliable stone jaw crusher for limestone, which is bearing huge torsion and made by the high-carbon steel. Eccentric shaft must be processed by finishing, heat treatment and the bearing should pouring by the use of the babbitt metal. There is a pulley at one side of the eccentric shaft , and the other side with the flywheel.
2.rack
the frame is a rigid frame with upper and lower opening. It is the support of the eccentric shaft and bears the reaction of broken material. And it requests enough strength and stiffness, generally wholly casting with the cast steel. Mini-machines can also cast with the high quality cast iron instead of cast steel. The frame of the mainframe need to cast segmentedly and then link into a firm whole with screws. The casting process is complex. The frame of homemade small jaw crusher can also weld with the thick plate but the stiffness is poorer.
3. Jaw plate and side guard board
dynamic jaw and static jaw are all made up of jaw bed and jaw plate, jaw plate is the working part and fixed to the jaw bed with bolts and wedge iron.
