Working Principle and Characteristics of Jaw Crusher
Working Principle
When the jaw crusher is in operation, the movable jaws move against the fixed jaws in a cyclical reciprocating motion, sometimes approaching and sometimes leaving. When it is close, the material is crushed by squeezing, splitting and impact between the two jaws; when it leaves, the crushed material is discharged from the discharge port by gravity.
The first crusher is usually the "main" crusher in the process of crushing huge boulders into small boulders. The oldest and most robust crusher is the jaw crusher. When feeding a jaw crusher, material is poured from the top entrance into the crushing chamber containing the jaws, which push the material against the chamber walls with great force, breaking it into smaller boulders. The movement of the jaw teeth is supported by an eccentric shaft that runs through the body frame. The eccentric motion is usually generated by flywheels fixed to the ends of the shaft. The flywheel and eccentric support bearings are often spherical roller bearings, which must withstand significant shock loads, abrasive effluent and high temperatures.
