Overview
The Z Series jaw crusher is the new-type crushing equipment YUANNAI manufactures. It comes with V type chamber and thereby its crushing capability is improved by ****0% in comparison with similar product with common chamber. 

This crusher not only suits for crushing limestone, medium hard iron ores and feldspar, but also enables to crush aggregates as well as dry and wet artificial sands. As a muti-purpose machine, our jaw crusher also comes with optional extras to meet your demands. 

Working principle
The upper part of movable jaw is in circular motion via rotation of eccentric shaft situated between lining plate and movable jaw. This elliptic motion triggers toggle plate to push movable jaw to move forwards and backwards. Once the movable jaw moves forth toward fixed jaw, materials will be squashed or chopped in crushed chamber. 

The crushed chamber of this limestone crusher performs crushing under the action of fixed jaw plate secured to machine rack and movable jaw plate installed on the movable jaw. After utter crushing, materials will be discharged out of machine. 

Features
Both movable jaw plate and toggle plate of the jaw crusher are designed with deviation rectifying function. 
Discharge gate adopts advanced hydraulic dual wedge-block adjusting device that is more convenient and efficient than gasket-type adjusting device. Manual adjustment can be completed within only several minutes without the trouble of handling dirty gasket. 
With optimized crushing chamber and motion parameters, the ironstone crusher is mainly made from superior manganese steel and thick steel plate. We also make use of finite element analysis for mechanical property evaluation to ensure that the jaw crusher can possess high load and impact resistance. 
Z Series Jaw Crusher double wedge block outlet adjusting system. This kind of adjusting system is easier, safer, faster than the old types that which are using adjuster shim. The crusher outlet can be adjusted manually within a few minutes by using the tools that we provided accompany with the crusher. No need to handle with the dirty and bloated shim.
