Calculating the Gforce of a Vibrating Screen
Jul 08, 2015 Once the motor speed has been calculated, the Gforce can be calculated using this formula: Gforce = (Stroke X w^2) / 1.8 X 10^6. where: Stroke = measured amplitude in mm. For optimal efficiency, a Gforce of 4.5  5.0 will supply sufficient acceleration to the feed to not clog or peg in the screening interface. Post not marked as liked.
