Automatic Discharging Dolomite Flint Jaw Crusher Machine With
Hydraulic Jaw plate Crusher machine for Dolomite Flint crushing have function of overload protection. It means that when suddenly
loaded by blovcks that can not be broken, the machine can instantly
auto-unload them by means of its hydraulic protection device, which
therefore effectively avoids excessive impact and blocking problem.
This type of crusher is often used in the crushing and processing
for metallurgical slags.
1. The crusher can be accordingly set with rated load to do
selective crushing for materials containing differernt compressive
2. The crushers have quite reliable functions of impact protection
and automatic discharging, which effectivelty resolve the blocking
problems for continuous production.

The uncrushed materials enter into the crushing chamber from the
upper feed opening, and then discharged from the lower discharge
opening after striking and crushing. Electric motor drives the
eccentric shaft to make the swing jaw up and down under the effect
of toggle plate and spring.
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 high pressure oil
supplied from the hydraulic system enters into oil chamber to push
the piston stay in the limit position. The nominal oil pressure of
hydraulic system of piston can provide a stable support seat in the
normal crushing operation. The piston will transfer the peak load
to the hydraulic system when the jaw plate meets some unbroken
materials, which will make the oil pressure reach the set value
rapidly, or more, and the pressure transmitter send signal, open
the routine between oil cylinder and oil tank. As a result, the
bear chamber oil tank release, and the swing jaw open discharge
opening under the function of spring to discharge hard crushed
materials, that is “iron passing”. After troubleshooting, block the
loop between oil tank and oil cylinder, and then the oil pressure
push the swing jaw reset to the set open size to make the machine
into the normal operation.
