Buyer''s Guide: Crushers

A jaw crusher is reliable and needs less maintenance than other types of crushers. A jaw crusher has one fixed and one moving surface in a V-shaped configuration. The moving "jaw" is mounted on an eccentric shaft. The reciprocal motion of this jaw presses the material against the fixed jaw. Rotational movement is achieved via a motor and a ...

What is the eccentric throw? — SRP

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 doesn''t stay in the center of the chamber – it sweeps around moving closer and further away from the concave. This is what creates the crushing action.
