PEY Series Hydraulic Jaw Crusher

PEY series hydraulic jaw crusher is one type tilting crusher with overload protection function. 

The load of machine will soar when crushing some unbroken materials, and then the hydraulic protection device can decrease the load automatically in order to avoid the sudden load greatly impacting the body. This machine can safely be used in the crushing projects of those foreign materials with extreme hardness.

19. After the bracket pad 20. Spring rod 21. Brackets
22. Front bracket pad

The Working principle of PEY Series Hydrulic Jaw Crusher:

Those materials being crushed will enter into the crushing chamber( made up of fixed tooth plate, movable tooth plate and side linings) from the upper, and discharged from the outlet of crushing chamber(discharging port) after being crushed by movable jaw plate. The activity of movable jaw plate is generated by the eccentric shaft rotating boosted by transmission part.
Hydraulic system is the overload protection device of the machine, which can reduce the loading pressure of the body in order to realize the purpose of protecting the body. The established sufficient hydraulic piston of hydraulic system can provide a stable support brackets in the normal crushing process. The brackets can transport the peak load to the oil system by piston when the jaw plate meets some unbroken materials, which will make the oil pressure reach the set value or more, and then the pressure of system will immediately signaled.

To open the cylinder path leading to the tank in order to reduce the pressure of oil cylinder, and the movable jaw will enlarge the discharging port under the power of weight and spring tension in order to discharge the unbroken materials, and this process can be named "over iron". To cut off the path between fuel tank and tank after solving the above problem, and to open the oil circuit of oil cylinder can make the machine operating again by recovering the prior discharging size.

This machine is made up of three main parts: pendulum jaw mainframe, hydraulic protection device and controlling cabinet.
