Npua chiv chiv granulation khoom
Pig manure fertilizer granulation khoom siv los hloov fermented npua manure rau hauv granular chiv kom yooj yim tuav, tsheb thauj mus los, thiab daim ntawv thov.Cov khoom siv yog tsim los hloov cov quav quav npuag rau hauv cov khoom me me, uas tuaj yeem ua raws li qhov xav tau loj, zoo li, thiab cov ntsiab lus zoo.
Cov khoom tseem ceeb ntawm npua quav chiv granulation khoom muaj xws li:
1.Disc granulator: Nyob rau hauv cov khoom siv no, cov xuab zeb xuab zeb composted tau muab tso rau hauv ib qho rotating disc, uas muaj cov suab nrov.Cov khoom raug yuam kom yob thiab tsim rau hauv cov pellets me me vim yog lub zog centrifugal tsim los ntawm cov rotating disc.Tom qab ntawd cov pellets tau qhuav thiab txias kom tsim tau cov chiv granular.
2.Nruas granulator: Nyob rau hauv cov khoom siv no, cov xuab zeb xuab zeb composted yog pub rau hauv ib lub nruas rotating, uas muaj ib tug series ntawm lifting flights los yog paddles.Cov khoom yog lifted thiab tumbled nyob rau hauv lub nruas, ua rau nws tsim rau hauv granules.Tom qab ntawd cov granules tau qhuav thiab txias kom tsim tau cov chiv zoo sib xws.
3.Extrusion granulator: Nyob rau hauv cov khoom siv no, cov khib nyiab khib nyiab raug yuam los ntawm lub phaj tuag nyob rau hauv siab siab los tsim cov cylindrical lossis spherical pellets.Cov phaj tuag tuaj yeem raug kho los tsim cov pellets ntawm ntau qhov sib txawv thiab cov duab.
4.Rotary granulator: Nyob rau hauv cov khoom siv no, cov khib nyiab khib nyiab tau pub rau hauv lub nruas rotary, uas muaj cov kab los yog cov hniav.Cov khoom yog lifted thiab tumbled nyob rau hauv lub nruas, ua rau nws tsim rau hauv granules.Tom qab ntawd cov granules tau qhuav thiab txias kom tsim tau cov chiv zoo sib xws.
Kev siv cov npua quav chiv granulation cov cuab yeej tuaj yeem pab tsim cov khoom sib xws, cov chiv zoo uas yooj yim los tuav, khaws cia, thiab siv.Cov khoom siv tuaj yeem hloov kho raws li cov kev xav tau tshwj xeeb ntawm kev ua haujlwm, suav nrog qhov loj, cov duab, thiab cov ntsiab lus ntawm cov granules.
