Vibrating screen efficiency calculaton methods

1. Calculation of the amount of burial:
Q= 3600*b*v*h*Y
Q: throughput, unit: t/h
b: sieve width, unit: m
h: average thickness of material, unit: m
γ : material density, unit: t/ m3
v: material running speed, unit: m / s
2. The calculation method of the running speed of linear vibration material is:
v=kv*λ *w*cos(6 ) * [1+tg(δ )*g(a ) ]
3. The calculation method of the running speed of the circular vibrating material is:
v=kv*λ *w2* (1+ ) *a ;
Kv: comprehensive experience coefficient, generally takes 0.75~0.95
λ: single amplitude, unit: mm

w: vibration frequency, unit: rad/ s

δ : vibration direction angle, unit: °
a : screen inclination, unit: °
4. Dynamic load: P = k*A
k: spring stiffness, unit: N/m
λ: amplitude, unit: m
P: dynamic load, unit: N
The maximum dynamic load (common vibration load) is calculated as 4 to 7 times the above result.
