1. Kev suav tus nqi ntawm kev faus neeg:
Q = 3600 * b * v * h * Y
Q: throughput, chav tsev: t/h
b: qhov dav ntawm lub sieve, chav tsev: m
h: qhov nruab nrab tuab ntawm cov khoom siv, chav tsev: m
γ: qhov ceev ntawm cov khoom, chav tsev: t/ m3
v: cov khoom siv khiav ceev, chav tsev: m / s
2. Txoj kev xam ntawm qhov ceev ntawm cov khoom siv linear vibration yog:
v=kv*λ *w*cos(6) * [1+tg(δ )*g(a)]
3. Txoj kev xam ntawm qhov ceev ntawm cov khoom siv vibrating voj voog yog:
v=kv*λ *w2*(1+) *a ;
Kv: tus lej kev paub dhau los, feem ntau siv 0.75 ~ 0.95
λ: ib qho amplitude, chav tsev: mm

w: zaus kev co, chav tsev: rad/ s

δ: lub kaum sab xis ntawm kev co, chav tsev: °
a: qhov screen inclination, unit: °
4. Kev thauj khoom dynamic: P = k * A
k: lub caij nplooj ntoos hlav tawv, chav tsev: N/m
λ: qhov dav, chav tsev: m
P: dynamic load, chav tsev: N
Qhov siab tshaj plaws dynamic load (kev co vibration load) yog xam raws li 4 txog 7 npaug ntawm qhov tshwm sim saum toj no.
