  • How do we check a frequency on a vibrating screen

    2021-8-27 · Answers. Resonance is creating the louder sound. The material is vibrating at its natural frequency. The answer to 1 is the sound quality. First and foremost, the problem specifies that it operates at a CERTAIN frequency. So, the natural frequency is not changing.2 firestoneip,frequency of the vibrating system is equal to the natural frequency of the suspension. When this happens, amplification of movement occurs. If the normal stroke of a vibrating screen, for example, is 5/16 of an inch (8 mm), during startup and shutdown (as the machine goes through resonance), the amplitude of movement will be multiplied. So while
