working stroke Eccentric Twin-Jaws Crusher

Since the present crusher utilizes the gyratory movement of the hinge, it can be compared with known gyratory crushers and eccentric-roll crushers (e.g. of Rapidex Inc. and Joy Manufacturing Co.). The working stroke of the present crusher is almost doubled in comparison with conventional jaw crushers. Therefore, it works more uniformly and lessens the required horsepower, dynamic load and mass ...

What is the eccentric throw? — Sandvik Mining and Rock ...

The eccentric throw is one of the most important parameters in defining the job that your cone crusher does. The mantle in a cone crusher spins in conical pendulum motion. That means it doesnrsquo;t stay in the center of the chamber ndash; it sweeps around moving closer and further away from the concave. This is what creates the crushing action. At a given point on the concave, material is ...
