## Circle-throw vibrating machine - Wikipedia

An external vibration exciter (motor) is mounted on the lateral (side) plate of the screen box with a cylindrical eccentric shaft and stroke adjustment unit. At the screen outlet, the flows are changed in direction, usually to 90 degrees or alternate directions, which reduces the exiting stream speed.

## Critical speed - Wikipedia

In solid mechanics, in the field of rotordynamics, the critical speed is the theoretical angular velocity that excites the natural frequency of a rotating object, such as a shaft, propeller, leadscrew, or gear.As the speed of rotation approaches the object's natural frequency, the object begins to resonate, which dramatically increases system vibration.

## Rotational and Torsional Vibration

Rotational vibration is simply the dynamic deviation of the rotation speed. If we measure the rotation speed of the shaft with high precision, we will notice that we get a high deviation of rotation speed in some regions of the run up. This is caused by the angular vibration crossing the angular natural frequency of the shaft.

The rotational velocity at which the vibration increases dramatically is called the "critical speed of the rotating mass. This characteristic for a shaft-mounted mass is called "settling of the wheel".
