  • Enduron Comminution Equipment

    Vibrating motion for a screen is provided by means of out-of-balance motors or geared exciters. Enduron vibrating screens use high g-force geared exciters for machines 2.4m (7' 7/8") and wider to provide the vibration motion required. The major part of the exciter drive is the housing, which is a cast metal enclosure and serves as an oil bath.

  • The Physics of Sound and Music

    Resonance. The vibrations of the aluminum force the air column inside of the rod to vibrate at its natural frequency. The match between the vibrations of the air column and one of the natural frequencies of the singing rod causes resonance. The result of resonance is always a big vibration - that is, a loud sound.

  • Nonlinear Model of Vibrating Screen to Determine

    Springs of vibrating screens are prone to fatigue induced failure because they operate in a heavy duty environment, with abrasive dust and under heavy cyclic loads. If a spring breaks, the stiffness at supporting positions changes, and therefore the amplitude of motion and the static and dynamic angular inclination of deck motion also change.
