• Checking the amplitude of a vibrating screen

     · One of the most important things to check on a periodic basis is the shape of the screen's vibratory motion. In Figure 1, one can see and verify the shape of the vibratory motion: circular (A), elliptical (B) or even linear (C). It is also possible to assess the amplitude of motion, as provided in Figure 2. Let's examine a few concepts related to amplitude: The amplitude of vibration .
