JC jaw crusher is successfully developed by NMS through advanced technology. It is widely used in various hard and abrasive rock. It is possible foundation bolts are not required due to the good balance of the crusher.
The crusher can operate by rubber dampers and stoppers, to efficiently absorb crushing load, avoid the damage to the crusher foundation.
Mechanical or hydraulic wedge CSS adjustment system is simpler and safer than the shim adjustment.
An integral motor base is mounted on the crusher frame to extend V-belt life and save the mounting space, the foundation can be more simple, while the standard belt wheel and the flywheel cover can be used.
