2013. 12. 22. modified version of the VSMA (Vibrating Screen Manufactures Association) formula to determine screen capacity. The twelve factors used in the formula below are based in large part on the VSMA charts and formula. Formula: A = B * S * D * V * H * T * K * Y * P * O * W * F “A”, the calculated capacity per square foot of screen area in tons per hour. B = Basic capacity per square foot in tons
Contactthe vibrating screen. Screen Capacity Formula T S = A x B x C x D x E x F S = Screening Area T = Tonnage Through the Deck A = Capacity in TPH Per Square Foot B = % of Oversize in feed Per Deck C = Desired Efficiency D = % of Feed less than Half Size Per Deck E = Wet Factor.

ContactUnidirectional Method. The material velocity of linearly vibrated screens can be obtained from the diagrams contained in appendix A-1. i = angle of incidence of the line of force in relation to the horizontal plane. e = eccentricity (mm) App = peak-to-peak (mm) = 2 x e.
ContactVibrating Screen Capacity Calculations MEKA. The material velocity of a circular vibrating screen can be calculated from the corrected theoretical speed of the product formula written below. Example: Determine the material velocity of a screen vibrated at 900 RPM with a 12 mm stroke and 20° degree inclination angle.

Contact2012. 9. 11. The following information is required to calculate the two screen efficiencies;-Qms(f) = Mass flow rate of solid feed. Qms(o) = Mass flow rate of solid in the screen overflow. Qms(u) = Mass flow rate of solid in the screen underflow. Mu(f) = Mass fraction of undersize in the feed. Mu(o) = Mass fraction of undersize in the overflow.
