2017-4-1 · The vibration intensity of the screen is a key parameter affecting the screen performance which can be characterised by the vibration frequency f (cycles per second), the amplitude A (mm) and the inclination angle of the screen deck α (degree). The vibration intensity of a circularly vibrating screen is defined by the vibration g-force, Γ: (1) Γ = A 2 π f 2 9.81 cos α
