Calculating the G-force of a Vibrating Screen

Jul 08, 2015  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. Post not marked as liked.
