Udidi lwesichumisi

Iindidi zezichumiso zinokwahlulwa ngokubanzi zibe zintlobo ezimbini: izichumisi ezingaphiliyo nezichumisi eziphilayo.
Izichumisi eziqhelekileyo zeekhemikhali ziquka izichumisi ze-nitrogen, izichumisi ze-phosphate kunye nezichumisi ze-potash, izichumisi ze-element ezibini, izichumisi zekhompawundi ezintathu kunye nezichumisi zekhompawundi ezininzi, kunye nezichumisi ze-organic-inorganic compound.
Izichumisi ze-inorganic zizichumisi zekhemikhali, ezifana ne-nitrogen eyahlukeneyo, i-phosphorus, izichumisi ze-potash okanye izichumisi ezidibeneyo.Izichumisi zemichiza eziqhelekileyo ezisetyenziswa kwishishini lokutyala ziquka: i-diammonium phosphate, i-urea, i-potassium sulfate, i-potassium chloride, kunye nezichumisi ezahlukahlukeneyo.Izichumisi ezisebenza ixesha elide ezifana ne superphosphate zingasetyenziswa nakumthi weziqhamo

(1) Isichumiso senitrogen.Oko kukuthi, izichumisi zeekhemikhali ezinezondlo ze-nitrogen njengeyona nto iphambili, njenge-urea, i-ammonium bicarbonate, njl. (2) Isichumisi sePhosphate.Oko kukuthi, izichumisi zeekhemikhali ezinezondlo ze-phosphorus njengeyona nto iphambili, njenge-superphosphate.(3) Isichumiso sePotassium.Oko kukuthi, izichumisi zeekhemikhali ezinezondlo ze-potassium njengeyona nto iphambili.Iindidi eziphambili ziquka i-potassium chloride, i-potassium sulfate, njl. (4) Isichumisi esidibeneyo.Oko kukuthi, isichumiso esiqulethe izinto ezimbini kwi-nitrogen, i-phosphorus kunye ne-potassium ibizwa ngokuba yi-binary compound fertilizer, kunye nesichumisi esihlangeneyo esiqulethe izinto ezintathu ze-nitrogen, i-phosphorus kunye ne-potassium ibizwa ngokuba yi-ternary compound fertilizer.5 .(6) Izichumisi eziluncedo kwizityalo ezithile: ezifana nentsimbi slag silicon isichumiso egalelwa irayisi.

Indlela yegranulation yesichumiso

1. Indlela yokuvuselela igranulation
Ukuvuselela igranulation kukufaka ulwelo oluthile okanye isibophelelo kumgubo ocolekileyo oqinileyo kwaye uwuxulube ngokufanelekileyo ukuze ulwelo kunye nomgubo ocolekileyo oqinileyo udibane ngokusondeleyo omnye komnye ukuvelisa amandla abambeneyo ukwenza iipellets.Indlela yokuxuba esetyenziswa ngokuqhelekileyo ngokujika, ukuqengqeleka kunye nohlobo lwekhethini-uhlobo oluwayo lwe-disc, i-conical okanye i-cylindrical drum ngexesha lokujikeleza.Ngokwendlela yokubumba, inokwahlulwa ibe yi-rolling pellets, i-mixed pellets kunye ne-powder agglomeration.Isixhobo esiqhelekileyo sibandakanya imigqomo yegranulating, ipleyiti yegranulator, icone drum granulators, idisc granulators, idrum granulators, kneaders, idrum mixers, powder blenders ((isando, shaft ethe nkqo) (uhlobo, uhlobo lwebhanti), umatshini wepellet owayo, njl. njl. indlela eshukumisayo kukuba izixhobo zokubumba zinesakhiwo esilula, umatshini omnye unomphumo omkhulu, kwaye iinqununu ezenziwe zilula ukuchithwa ngokukhawuleza kwaye zibe nokumanzi okumanzi okunamandla kukuba ukufana kweengqungquthela kubi, kunye nesiphumo Amandla e-particle aphantsi Okwangoku, amandla okusebenza kolu hlobo lwezixhobo angafikelela kwiitoni ezingama-500 / iyure, kwaye i-particle ububanzi inokufikelela kwi-600 mm Ininzi ifanelekile ukusetyenzwa kwamaminerali, izichumisi, iikhemikhali ezintle. ukutya kunye namanye amasimi.

2. Indlela yokubilisa igranulation
Indlela yokubilisa igranulation yeyona isebenzayo phakathi kweendlela ezininzi.Umgaqo kukusebenzisa umoya ovuthuzayo ukusuka ezantsi kwesixhobo ukudada amasuntswana omgubo kunxibelelwano olupheleleyo nodaka olutshizwe kumpu wokutshiza ongentla uze ungqubane omnye nomnye ukudibanisa amasuntswana.Amasuntswana avelisiweyo yile ndlela akhululekile ngokwentelekiso, anobunzima obuyi sphericity kunye nokuphela komphezulu.Zifanelekile ukuvelisa amaqhekeza aneemfuno eziphantsi okanye ukulungiswa kwangaphambili kwamanye amalungiselelo.Le ndlela kukuqwalasela i-cylinder encinci ye-diameter okanye i-cylinder yokwahlula embindini wecala elisezantsi le-cylinder ye-granulation ebilayo, kwaye usasaze indawo yokungena umoya we-hot air ventilation plate orifice ezantsi ukuba ibe nkulu embindini. kwaye kuncinci kumacala ajikelezileyo, okukhokelela kwimeko apho izinga lokuhamba komoya oshushu embindini likhulu kuneendawo ezingqongileyo.Ngaphantsi kweempembelelo zamandla omoya ahlukeneyo, amasuntswana adada ukusuka phakathi kombhobho ongundoqo kwaye adibane ne-adhesive efakwe kwi-spray gun efakwe embindini wezantsi.Emva koko ziboshwe kunye nomgubo owela ukusuka kwindawo ephezulu kwaye emva koko zihlale ukusuka ngaphandle kombhobho ongundoqo ukwenza isakhiwo se-particle.Ijikeleza phezulu naphantsi ukufezekisa injongo yokwenza amaqhekeza akhule ngokulinganayo.

3. Indlela ye-Extrusion granulation
Indlela ye-Extrusion okwangoku yeyona ndlela iphambili yoxinzelelo lokwenza igranulation kwishishini lelizwe lam lomgubo.Izixhobo ze-Extrusion granulation zinokwahlulwa zibe yi-vacuum rod granulators, enye (ephindwe kabini) i-screw extrusion granulators, imodeli yomatshini wokugxiviza, i-plunger extruders, i-roller extruders, kunye ne-counter mixers ngokwemigaqo yabo yokusebenza kunye nezakhiwo.I-gear granulator, njl. Olu hlobo lwezixhobo lunokusetyenziswa ngokubanzi kwishishini lepetrochemical, ishishini lemichiza ephilayo, imboni yeekhemikhali ezilungileyo, amayeza, ukutya, ukutya, isichumisi kunye nezinye iindawo.Le ndlela ineenzuzo zokuguquguquka okunamandla, imveliso enkulu, ubungakanani bamasuntswana afanayo, amandla amasuntswana amahle, kunye nezinga eliphezulu legranulation.
