The fourth step is to calculate the frequency ratio. The frequency ratio is equal to the operating or exciting frequency divided by the circular natural frequency of the system. The frequency ratio is a unit less parameter. The fifth step is to calculate the amplitude of the forced vibration response.

Jul 08, 2015· Number of poles of the motor. Stroke of the screen (measured) Frequency of the current to the motor. From the number of poles of the motor, the moto's shaft rotational speed can be calculated, using the following formula: w = (2 X 60 X f) / n where: w = shaft rotational speed, RPM. f = frequency, Hz. n = number of poles of the motor
C. VIBRATING SCREENS Rule of Thumb: for selfcleaning screen use a vibrator with a centrifugal force (impact) four (4) times the weight of the material plus the weight of the screen. NOTE: Coarse and lumpy materials respond best to 3600 VPM (vibrations per minute), powdery and dry materials, 1800 VPM, sticky and wet materials, over 3600 VPM.
