2021-8-9 2. Vibrating screen amplitude and frequency. Vibrating screen amplitude refers to the range and intensity of the box vibration, and frequency refers to the number of vibrations per minute of the screen box. When the amplitude is larger, the frequency of screening is higher, and the movement speed and acceleration of the screen box are also greater.

2015-8-31 This bearing must have a peak speed of 7x the first bearing. The relationship between the 3 is linear (e.g. if the frequency increases 7x and the displacement remains same, the velocity must increase 7x). So increasing the frequency 7x while leaving the displacement the same results in increasing the velocity at which the bearing must move by 7x.
