Tsis qhuav extrusion granulation ntau lawm kab
Ib txoj kab uas tsis muaj kev ziab extrusion granulation ntau lawm yog txheej txheem los tsim cov chiv granulated yam tsis tas yuav ua kom qhuav.Cov txheej txheem no siv kev sib xyaw ua ke ntawm extrusion thiab granulation thev naus laus zis los tsim cov tshuaj zoo tshaj plaws granules.
Ntawm no yog ib qho kev qhia dav dav ntawm cov khoom siv tsis-drying extrusion granulation:
1.Raw Material Handling: Thawj kauj ruam yog los sau thiab lis cov ntaub ntawv raw.Cov khoom siv raw siv hauv kev tsim cov chiv granulated tuaj yeem suav nrog nitrogen, phosphorus, thiab potassium (NPK) chiv, nrog rau lwm cov organic thiab inorganic cov ntaub ntawv xws li tsiaj quav, qoob loo residues, thiab cov khoom lag luam.
2.Crushing: Cov ntaub ntawv raw yog ces crushed rau hauv me me pieces los pab txhawb kev sib tov.
3.Mixing: Cov khoom nyoos crushed yog tov ua ke siv lub tshuab sib tov los tsim ib homogeneous sib tov.
4.Extrusion Granulation: Cov khoom sib xyaw yog ces muab tso rau hauv ib qho extrusion granulator, uas siv cov kev kub siab thiab cov ntsia hlau los yog cov chais rau compress cov ntaub ntawv rau hauv me me pellets los yog granules.Cov extruded pellets los yog granules yog ces txiav mus rau qhov xav tau loj siv lub cutter.
5.Cooling and Screening: Cov granules extruded ces txias thiab tshuaj ntsuam kom tshem tawm tej yam oversize los yog undersize hais, kom ntseeg tau ib yam khoom zoo ib yam.
6.Coating: Cov tshuaj ntsuam xyuas granules yog tom qab ntawd coated nrog ib txheej ntawm cov khoom siv tiv thaiv kom tsis txhob muaj caking thiab nce lub neej cia.Qhov no tuaj yeem ua tiav siv lub tshuab txheej.
7.Packaging: Cov kauj ruam kawg yog ntim cov granules rau hauv hnab lossis lwm lub thawv, npaj rau kev faib thiab muag.
Qhov zoo ntawm qhov tsis muaj kev ziab extrusion granulation cov kab ntau lawm suav nrog kev siv hluav taws xob qis thiab txo kev cuam tshuam ib puag ncig piv rau cov txheej txheem ziab khaub ncaws.Tsis tas li ntawd, cov txheej txheem no tuaj yeem tsim cov chiv granulated nrog qhov loj me me thiab cov ntsiab lus zoo, uas tuaj yeem txhim kho cov txiaj ntsig zoo thiab cov qoob loo qoob loo.
Zuag qhia tag nrho, tsis muaj-qhuav extrusion granulation ntau lawm kab tuaj yeem yog txoj hauv kev zoo thiab raug nqi ntawm kev tsim cov qoob loo zoo granulated.Txawm li cas los xij, cov cuab yeej tshwj xeeb thiab cov tshuab yuav tsum tau tsim cov granules nrog cov yam ntxwv xav tau.
