Yakajairika fetireza extrusion granulators inosanganisira kaviri-mupumburu extrusion granulator uye flat (mhete) die extrusion granulators.Panguva yekugadzirwa kwemafetireza emukomboni, aya magranulator anogona kuwedzera zvinhu zvenitrogen zvichienderana nezvinenge zvichidiwa, uye mamwe anoshandisa urea semunobva zvinhu zvenitrogen, izvo zvinokwanisa kutora mwando mumhepo zviri nyore zvokonzera kuti mafetireza emusanganiswa abatane.Naizvozvo, zvinowanzotaurwa kuti iyo kaviri-roll extrusion granulator ndeye yakaoma poda granulator, iyo ine mhedzisiro iri nani pakugadzira granules yezvakagadzirwa zvinhu zvine mwando zvisingasviki 10%.Pazvinhu zvakanyorova, tekinoroji inodiwa yekurwisa-kuomesa inofanira kuitwa.Nekuchengetedza mafetiraiza granules ane hunyoro sezvinhu zvakabikwa zvemafetireza akakoniwa, zvinodikanwa kudzivirira kuoma.
Iyo musimboti uye chinodiwa chemvura chemukomboni fetireza extrusion granulator kugadzirisa granules
Iyo yekushanda musimboti weiyo extrusion granulator inonyanya kuoma poda seyakanyanya mbishi zvinhu.Kana iyo brittle material yakasvinwa, chikamu chezvikamu zvinopwanyika, uye hupfu hwakatsetseka hunozadza mazamu pakati pezvikamu.Muchiitiko ichi, kana zvisungo zvekemikari zvemahara panzvimbo ichangobva kugadzirwa hazvigone Kukurumidza kuzadzwa nemaatomu kana mamorekuru kubva kumhepo yakatenderedza, nzvimbo dzichangogadzirwa dzinosangana uye dzinogadzira mabhondi akasimba ekubatanidza.Nekuwedzeredza kwe roller, ganda re roller rine spherical yakatarisana groove, iyo inokwidziridzwa kuita spherical chimiro, uye zvimedu zvakaburitswa neflat (mhete) kufa ndeye columnar.Extrusion granulation inoda hunyoro hushoma.Kana unyoro hwakanyanyisa, zvakakosha kuwedzera hurongwa hwekuomesa kune teknolojia yekugadzirisa.
Mhinduro kune yakashata mhedzisiro yenitrogen sosi mwando yekunyudza mhando mukomboni fetireza granulation process
Iyo crux ye compaction mukomboni fetireza granulation process inonyanya kuve yakakwira mvura yemukati inokonzerwa nenitrogen sosi urea inonwisa mvura.Kutaura nemechanist, kutanga uye kumhanya kwe "kupisa zvishoma nezvishoma" kwefotereza yekomboni hakuwedzere nekuwedzera kweammonium nitrate uye potassium chloride.Semuenzaniso, musanganiswa une 80% ammonium nitrate uye 20% potassium chloride haipisi, asi ine Musanganiswa we 30% diatomaceous earth, 55% ammonium nitrate, uye 15% potassium chloride inobereka yakasimba "inononoka kupisa".
Compound fetireza particles ane urea senitrogen sosi ane yakakwira hygroscopicity uye yakaderera kupfava poindi;biuret uye adducts anoumbwa nyore nyore kana tembiricha yakakwira;urea ichave iine hydrolyzed kana tembiricha yakakwira, zvichikonzera kurasikirwa kweammonia.
Izvi zvinodikanwa kugadzirisa iyo yakakwirira yemvura yemukati inokonzerwa neiyo nitrogen sosi inotora mvura.Deredzai nitrogen sosi Kana calcium superphosphate iripo, phosphorus inonyungudika nemvura ichaderedzwa;paunenge uchigadzira urea-yakajairika calcium superphosphate fetiraiza, yakajairika superphosphate inofanira kugadziridzwa, senge ammoniation, inogona kubvisa maadducts Gadzira, kana kuwedzera calcium magnesium phosphorus kuderedza iyo yemahara asidhi ye superphosphate, uye kushandura mvura yemahara kuita sekristaro mvura, kuvandudza chigadzirwa. kunaka, kana kuwedzera ammonium sulfate, iyo inogona kuderedza unyoro hwechigadzirwa chakapedzwa uye kusimbisa kuoma kwechigadzirwa chakapedzwa;kana pane chlorine Kana ammonium inoshandurwa, urea neklorini inoumba adduct, iyo inowedzera crystallization, iyo inoita kuti fetiraiza inodziya ive nyore kukonzera agglomeration yechigadzirwa chakapedzwa panguva yekuchengetedza;saka, iyo fetireza yekomboni ine urea seyo nitrogen sosi inofanirwa kubhadhara zvakanyanya kuomesa uye kutonhora maitiro.Semuenzaniso, tembiricha yekuomesa haifanirwe kunge yakakwira zvakanyanya, nguva yekuomesa haifanirwe kureba, hunyoro hunotsanangurwa mumhando yemhando hunofanirwa kusangana, chiitiko chekunyunguduka panguva yekugadzira chinofanirwa kudzivirirwa, uye hapana caking inofanira kuchengetwa. panguva yekuchengetedza.
Izvo zviri pamusoro ndizvo zvikonzero zvehunyoro hwepamusoro mugwaro regranulation yecompound fertilizer granulator, iyo inokonzera compaction.Nzira huru yekudzivisa kusungirirwa ndeye kushandiswa kwekuomesa system.Pretreatment yezvishandiso, kuwedzera kwezvinhu uye dzimwe nzira, kuitira kuti uone kugadzirisa uye kusiri-kuparadza kuchengetedza kweakasanganiswa fetiraiza zvimedu.
