What is the eccentric throw?
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. At a ...

Gyratory Crusher (Gyratory Crushers Explained)
Eccentric motion is achieved by the lower eccentric bushing and drive arrangement on the bottom of the main shaft. The input pinion drive countershaft is supported by pinion bearings and powered by an electric motor. An external gearbox or belt drive arrangement reduces the motor speed to approximately 100-200 RPM at the crusher.

The importance of the right mantle and concave
This measures the pendular movement of the mantle. The greater the eccentric throw, the more the mantle moves away from its axis. Matching the mantle and the eccentric throw is a crucial step to ensuring optimal output and an even wear pattern.

The cone crusher working principle involves the eccentric motion of the main shaft. This motion is created by the rotation of the main shaft, which is supported by a bearing located at the top of the machine. As the main shaft rotates, it causes the mantle to move back and forth against the concave, crushing the rocks and ores between them.
