Automatic Discharging Dolomite Flint Jaw Crusher Machine With Impact Protection


Description

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.

Product Features


1. The crusher can be accordingly set with rated load to do selective crushing for materials containing differernt compressive strengths.

2. The crushers have quite reliable functions of impact protection and automatic discharging, which effectivelty resolve the blocking problems for continuous production.

Working Principle


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.
