关风器排料量G计量公式：
G：0.06V.N.Y.R.K（吨/小时）
V-关风器容量（升/转） N-关风器转速（转/分）
Y-关风器容量积效率：颗粒状物料r-0.8；粉状物料r=0.5~0.6
R-物料容量（吨/米3）K-修正系数，一般取0.7~0.8
Material Discharging Amount of Airlock Is Calculated According to the Following Formula:
G:0.06V.N.Y.R.K(t/h)
V-volume of airlock(l/r) N-Rotating speed of airlock(r/min)
Y-volumetric efficiency of airlock:grain material r-0.8;powder material=0.5~0.6
R-Matirial capacity (t/m3) K-Reduction coefficient, generally0.7~0.8
