Vibratory Screens McLanahan

Screening is an important part of processing and is used to separate material according to its size. Material is typically fed to a single-, double- or triple-deck screen to make the required sizes. Screens can be considered the cashbox of the operation, because while crushers make the gradation, screens make the specification. Material must go through or over a specified size to end up in the ...

Calculating the G-force of a Vibrating Screen

2015-7-8  n = number of poles of the motor. 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.
