How to adjust of vibration amplitude of circular vibro screen?
The operating of Circular vibro screen machine is still in the vibration, so we should make sue the quality of vibrating screen machine is good, and also take care of the vibration amplitude.Normally it is 3~5 mm. In fact, the amplitude of every vibro screen is different, that;s why we cant make the amplitude is fixed data.

Measuring Vibration with Accelerometers
Vibration is the movement or mechanical oscillation about an equilibrium position of a machine or component. It can be periodic, such as the motion of a pendulum, or random, such as the movement of a tire on a gravel road. Vibration can be expressed in metric units (m/s 2) or units of gravitational constant g, where 1 g = 9.81 m/s 2.
