Once the motor speed has been calculated, the G-force can be calculated using this formula: G-force = (Stroke X w^2) / 1.8 X 10^6. where: Stroke = measured amplitude in mm. For optimal efficiency, a G-force of 4.5 - 5.0 will supply sufficient acceleration to the feed to not clog or peg in the screening interface. 1 like.

Screening can very easily be viewed as the most important operation in the processing plant. If the screen is only operating at 75% efficiency, then 25% of the desired product is going somewhere else. The performance of a screen is affected by four variables: eccentric throw, frequency (rpm), angle of adjustment and throw direction.
