Mokhoa oa granulation ea manyolo

Ts'ebetso ea granulation ea manyolo ke mohato oa bohlokoa tlhahisong ea menontsha ea boleng bo holimo.E kenyelletsa ho fetola lisebelisoa hore e be li-granules tseo ho leng bonolo ho li tšoara, ho li boloka le ho li sebelisa.Manyolo a nang le granulated a fana ka melemo e mengata, ho kenyelletsa phepelo e ntlafalitsoeng ea limatlafatsi, tahlehelo e fokotsehileng ea limatlafatsi, le ho ja lijo tse matlafatsang.

Mothati oa 1: Tokisetso ea Lintho tse tala
Mokhahlelo oa pele oa ts'ebetso ea granulation ea manyolo e kenyelletsa ho lokisa lisebelisoa tse tala.Sena se kenyelletsa ho fumana le ho khetha lisebelisoa tse nepahetseng ho latela sebopeho sa limatlafatsi tse lakatsehang le thepa ea 'mele.Lisebelisoa tse tloaelehileng tsa manyolo li kenyelletsa mehloli ea naetrojene (e kang urea kapa ammonium nitrate), mehloli ea phosphorus (e kang phosphate rock kapa phosphoric acid), le mehloli ea potasiamo (e kang potassium chloride kapa potassium sulfate).Li-micronutrients tse ling le li-additives le tsona li ka kenyelletsoa ha ho etsoa.

Mothati oa 2: Ho kopanya le ho kopanya
Hang ha lihlahisoa tse tala li khethiloe, li kena ka mokhoa oa ho kopanya le ho kopanya.Sena se tiisa kabo e ts'oanang ea limatlafatsi ho pholletsa le motsoako oa manyolo.Ho kopanya ho ka etsoa ka lisebelisoa tse fapaneng tse kang li-mixer tsa drum, li-mixer tsa paddle kapa li-mixer tse tšekaletseng.Sepheo ke ho finyella motsoako o tsitsitseng o fanang ka boemo bo leka-lekaneng ba limatlafatsi bakeng sa phepo e nepahetseng ea limela.

Mothati oa 3: Granulation
Mokhahlelo oa granulation ke moo lisebelisoa tsa manyolo tse tsoakiloeng li fetoloang ho li-granules.Ho na le mekhoa e fapaneng ea granulation e fumanehang, ho kenyelletsa:

Drum Granulation: Ka mokhoa ona, motsoako oa manyolo o kenngoa ka har'a granulator ea moropa e potolohang.Ha moropa o ntse o potoloha, thepa e khomarela holimo 'me e etsa li-granules ka motsoako oa ho bilika, ho kopanya le ho holisa boholo.Joale li-granules li omisitsoe ho tlosa mongobo o feteletseng le ho ntlafatsa botsitso.

Extrusion Granulation: Extrusion granulation e kenyelletsa ho qobella motsoako oa manyolo ka extruder, e nang le lefu le nang le boholo bo itseng ba lesoba le libopeho.Khatello le matla a ho kuta li etsa hore thepa e etse li-cylindrical kapa spherical granules ha e ntse e ntšoa ka lefu.Ka mor'a moo, li-granules lia omisoa ho fihlela mongobo o lakatsehang.

Spray Granulation: Ka har'a granulation ea spray, likarolo tsa mokelikeli tsa motsoako oa manyolo, joalo ka tharollo ea urea kapa phosphoric acid, li fetoloa marotholi a matle.Joale marotholi ana a fafatsoa ka phaposing e omisang moo a tieang ho ba granule ka ho fetoha mouoane oa mokelikeli.Li-granules tse hlahisoang li omisitsoe ho ea pele ho fihlela boemo ba mongobo bo lakatsehang.

Mothati oa 4: Ho omisa le ho Pholisa
Ka mor'a ts'ebetso ea granulation, li-granules tse sa tsoa thehoa hangata li omisitsoe le ho pholile ho ntlafatsa botsitso ba tsona le ho thibela ho baka.Sena se etsoa ho sebelisoa lisebelisoa tse khethehileng tsa ho omisa le tse pholileng tse kang li-dryer tsa rotary kapa li-coolers tse nang le metsi.Mokhoa oa ho omisa o tlosa mongobo o feteletseng, ha mokhoa oa ho pholile o fokotsa mocheso oa li-granules pele o paka kapa o tsoela pele ho sebetsa.

Melemo ea Fertilizer ea Granulated:

Phallo e Laolehileng ea Limatlafatsi: Manyolo a granulated a ka etsoa ho lokolla limatlafatsi butle-butle, ho fana ka phepelo e tsitsitseng ea limatlafatsi ho limela ka nako e telele.Sena se khothalletsa ho kenngoa ha limatlafatsi ka katleho le ho fokotsa kotsi ea ho tsoa kapa ho phalla ha limatlafatsi.

Kabo e sa Tšoaneng ea Limatlafatsi: Ts'ebetso ea granulation e netefatsa hore limatlafatsi li aroloa ka ho lekana ka har'a granule ka 'ngoe.Sena se fana ka monyetla oa ho ba teng ha limatlafatsi tse tsitsitseng le ho amoheloa ke limela, ho baka kholo ea lijalo tse tšoanang le chai e ntlafetseng.

Ho Tšoaroa le Tšebeliso e Ntlafetseng: Menontša e nang le granulated e ntlafalitse litšobotsi tsa 'mele, tse kang ho eketseha ha sekhahla le ho fokotsa lerole.Litšobotsi tsena li etsa hore ho be bonolo ho li tšoara, ho li tsamaisa le ho li sebelisa ho sebelisa lisebelisoa tsa ho hasanya, e leng se lebisang ts'ebetsong ea manyolo e nepahetseng le e sebetsang hantle.

Tahlehelo ea Limatlafatsi tse Fokotseng: Manyolo a nang le granulated a na le ho qhibiliha ho tlase ha a bapisoa le menontsha ea phofo kapa ea kristale.Sena se fokotsa kotsi ea tahlehelo ea limatlafatsi ka leaching kapa volatilization, ho netefatsa hore karolo e phahameng ea limatlafatsi tse sebelisoang li fumaneha ho limela.

Ts'ebetso ea granulation ea manyolo e phetha karolo ea bohlokoa ho fetoleng thepa e tala hore e be menontsha ea boleng bo holimo.Ka mekhahlelo e kang ho lokisetsa lisebelisoa tse tala, ho kopanya le ho kopanya, granulation, le ho omisa le ho pholile, mokhoa ona o etsa li-granules tse sa tšoaneng, tse laoloang-ho lokolloa tse nang le kabo e ntlafetseng ea limatlafatsi le thepa e ntlafetseng ea ho sebetsana le eona.Manyolo a nang le granulated a fana ka melemo e kang ho lokolloa ha limatlafatsi tse laoloang, kabo ea limatlafatsi tse tšoanang, ho tšoara habonolo, le tahlehelo e fokotsehileng ea limatlafatsi.
