Quritish barabanining hajmi:
Vbar=W/m0=1538/62=24.8 m3
Quritish barabanining uzunligi diametriga nisbati quyidagicha Lbar/Dbar=5 deb qabul qilamiz GOST 5151-71 buyicha.U holda diametri quyidagicha aniqlanadi:
Vbar=SLbar=(пD2/4)Lbar=0.785D2bar*5Dbar=3.9D3bar
Dbar = 3√ bar/3,9 = 3√ 24.8/3.9= 1.85 м Dbar=1.85m deb qabul qilamiz.
Quritish barabanining xajmini aniqlashtirib olamiz:
Vbar=3.9D3 bar=3.9*(1.85)3=24.69 m3 Quritish barabanining yuzasi va uzunligini aniqlab olamiz:
S=(пD2/4)=0.785*(1.85)2=2.68 m2
Lbar=Vbar/S=24.69/2.68=9.21 m Barabanning uzunliga Lbar=10 m.U holda Lbar/Dbar=10/1.85=5.4
Quritilgan material buyicha barabanning unumdorligini aniqlaymiz:
Bu yerda:
W=m0*Vbar=62*24.69=1530.78 kg/soat
U holda:
G2=62*24.69*(100-9)/(9-5)= 34825.245 kg/soat.
Namlik buyicha barabanning haqiqiy hajmiy zuriqishi:
34825.245=m0*24.69*(100-9)/(9-5) m0=62 kg/(m3*soat)
p-tuproqning urtacha namligida wo’r zichligi (kg/m3): wo’rt=(w1+w2)/2=(9+5)/2=14/2=7%
p=pk*100/(100-wo’rt)=1350*100/(100-7)=1451.61 kg/m3
Materialning barabanda bo’lish vaqtini quyidagi formuladan aniqlaymiz:
