How To Calculate Eccentric Weight In Vibrating Screen

Screen Vibration Eccentric Shaft With Only 2 Bearing. The screen was running at 860 rpm and the structure has been vibrating like crazy since changes were made to the shaftcounter weight bearing housing frame these changes were made prior to my arrival.We tried to get rid of the vibration by increasing the speed and it worked but the screen is now running at 1020 rpm with a stroke of 38.

Calculating the G-force of a Vibrating Screen

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

AB-027 : Eccentric Mass Parameters for Vibration Motors ...

$$Total \: mass \: Area = \pi r^2_{mass} – \pi r^2_{SHAFT} = \pi( r^2_{mass} – r^2_{SHAFT})$$ Should we later wish to calculate the weight of the mass we would first need to calculate the volume of the mass, this is achieved with the following formula: $$Volume = Total \: mass \: Area \times Height$$

Balancing a Four Bearing Single Shaft Screen

30/04/2012  4. If the screen is unbalanced, I think that the screen vibrates like a 2-bearing single shaft screen driven by 2 unbalanced weight dampened by the Rosta mounts and has an extra point where it won't be able to be overloaded as the screen is driven with the eccentricity of the shaft design. am I correct or not? 5. Why is the stroke varies ...
