Liming on a new jaw crusher arm bearings, spherical bearings in the form of uniform absorption of the load in all directions, with the abolition of the traditional rotary crusher arm bushings on the consumable parts, greatly improving the running reliability and significantly reduces operating costs. Using a large stroke hydraulic cylinder design, port of discharge can be adjusted within a broader context, this feature will help to ensure the ideal product size, to adapt the long-term needs. Design and durability.
