The materials become close to each other, and squeeze each other.
When the pressure rose to more than the strength of the material can withstand, they will be broken.
Conversely, when the movable jaw leaves the fixed jaw to swing in the opposite direction, the material is doing downward movement by gravity.
Each periodic movement of the movable jaw will crush the materials once.
After several periods, the crushed materials can be discharged from the discharging port.
Jaw crushers have many advantageous characteristics, such as low producing cost, high performance, perfect stabilization and separated lubrication.
Let me explain these advantages one by one.
As for the low producing cost, the jaw crusher has high producing capacity, high reliability and convenient maintenance, which contributes a lot to the result as low producing cost.
In terms of the performance, the moving jaw of the jaw breaker is made of high qualified cast steel, and the heavy eccentric bearing is produced with forging stock, which makes the machine more reliable and durable.
The stable jaw breakers are equipped with a wedge nesting adjustment device, and it is much simpler, safer and faster than the old gasket adjustment.
Finite element analysis techniques make the strength of the machine higher.
The reliability of jaw crusher shows in the advanced bearing of moving jaw, which is more durable.
The movable jaw assembly adopts high-quality steel castings, and drives through two large cast steel flywheels. In addition, heavy eccentric shaft has also adopted forging billet for processing, so all of this makes the PE series jaw crushers with exceptional reliability.
The eccentric shaft bearings are usually centralized circulation lubrication.
The supporting surface of spindle and thrust plate generally use the grease to oil through the oil gun manually.
The swing angle of moving jaw is very small, so that the spindle and bearing lubrication is very difficult, therefore, at the bottom of bush a number of axial oil groove are created, a ring oil groove connected to the sump is also be created in the middle, and then forced into the dry butter with the oil pump to finish the lubrication.
Simple structure, convenient maintenance and operation, stable performance, low cost and large crushing ratio make China jaw crusher famous in many industries.
