Fetereza chikamu

Mhando dzefetireza dzinogona kukamurwa zvakafara kuita mhando mbiri: inorganic fetereza uye organic fetereza.
Mafetereza emakemikari akajairwa anosanganisira elemental nitrogen fetiraiza, phosphate feteraiza uye potashi fetereza, maviri-element musanganiswa mafetiraiza, matatu-element musanganiswa mafetireza uye akawanda-element compound fetereza, pamwe neorganic-inorganic compound fetereza.
Inorganic fetiraiza imakemikari mafetiraiza, akadai seasiyana nitrogen, phosphorus, potashi fetereza kana mafetireza emukomboni.Mafetereza emakemikari anowanzoshandiswa muindasitiri yekudyara anosanganisira: diammonium phosphate, urea, potassium sulfate, potassium chloride, uye mafetireza akasiyana siyana.Mafetereza akareba senge superphosphate anogonawo kushandiswa pamuti wemichero

(1) Fetereza yeNitrogen.Ndiko kuti, makemikari mafetiraiza ane nitrogen zvinovaka muviri sechinhu chikuru, senge urea, ammonium bicarbonate, nezvimwewo (2) Phosphate fertilizer.Ndiko kuti, makemikari mafetiraiza ane phosphorus zvinovaka muviri sechikamu chikuru, senge superphosphate.(3) Fetereza yePotassium.Ndiko kuti, makemikari mafetiraiza ane potassium zvinovaka muviri sechinhu chikuru chikamu.Mhando huru dzinosanganisira potassium chloride, potassium sulfate, nezvimwewo (4) Compound fertilizer.Kureva kuti fetireza ine zviviri zvezvitatu zvenitrogen, phosphorus ne potassium inodaidzwa kuti binary compound fertilizer, uye fetireza yekomboni ine zvinhu zvitatu zvenitrogen, phosphorus nepotassium inonzi ternary compound fertilizer.(5) Trace element mafetireza uye mamwe epakati element mafetiraiza: ekutanga senge mafetireza ane trace elements senge boron, zingi, iron, molybdenum, manganese, mhangura, nezvimwewo, uye ekupedzisira senge calcium, magnesium, sulfur nemamwe mafetireza .(6) Fetereza inobatsira kune zvimwe zvirimwa: sesimbi slag silicon fetiraiza inoiswa pamupunga.

Fertilizer granulation nzira

1. Kukurudzira granulation nzira
Kukuchidzira granulation ndiko kupinza imwe mvura kana binder muhupfu hwakatsetseka hwakasimba uye nekuikurunga nenzira kwayo kuitira kuti mvura uye yakasimba poda yakatsetseka zviri pedyo nepedyo kuti ibudise simba rakabatana kugadzira pellets.Iyo inonyanya kushandiswa kusanganisa nzira ndeyekutenderera, kutenderedza uye keteni-mhando yekudonha kufamba kwedhisiki, conical kana cylindrical drum panguva yekutenderera.Zvinoenderana neiyo nzira yekuumba, inogona kukamurwa kuita rolling pellets, yakasanganiswa pellets uye poda agglomeration.Midziyo yakajairika inosanganisira madhiramu ekugezera, madhiramu epureta, cone drum granulators, disc granulators, dhiramu granulators, kneader, drum mixers, poda blenders ((sando, vertical shaft) (rudzi, rudzi rwebhandi), muchina unodonha wepellet, nezvimwe. iyo inokurudzira nzira ndeyokuti michina yekuumba ine chimiro chakareruka, muchina mumwe chete une goho rakakura, uye zvimedu zvakaumbwa zviri nyore kunyungudika nekukurumidza uye zvine simba kunyorova ndiko kuti kuenzana kwezvimedu kwakashata, uye zvinoguma Iko kusimba kwechikamu kwakaderera Parizvino, simba rekugadzirisa remhando iyi yemidziyo inogona kusvika kusvika 500 toni / awa, uye chidimbu chechidimbu chinogona kusvika kusvika 600 mm Inonyanya kukodzera kushandiswa kwemaminerari, mafetiraiza, makemikari akanaka. chikafu nemimwe minda.

2. Kubikira granulation nzira
Iyo yekubikira granulation nzira ndiyo inonyanya kushanda pakati penzira dzakati wandei.The musimboti kushandisa mhepo kuvhuvhuta kubva pasi midziyo kuti kuyangarara upfu zvimedu kupinda zvizere kusangana ne slurry akapfapfaidza kubva yokumusoro pfapfaidzo pfuti uye ipapo kudhumhana nomumwe kuti kubatanidza kuva zvidimbu.Zvimedu zvinogadzirwa neiyi nzira hazvina kurongeka, zvine hurombo hwechokwadi sphericity uye pamusoro pekupedzisira.Izvo zvakakodzera kugadzira zvimedu zvine zvakaderera zvinodiwa kana kuti pre-kugadzirisa mamwe magadzirirwo.Iyi nzira ndeyekugadzirisa diki-diameter core cylinder kana yekuzviparadzanisa cylinder pakati pechikamu chezasi chegiyadhi granulation cylinder, uye kugovera nzvimbo yekufefetera yemhepo inopisa yekufefetera orifice plate pazasi kuti ive yakakura pakati. uye zviduku kumativi akapoteredza, zvichiita kuti pave nemamiriro ezvinhu apo mhepo inopisa inoyerera pakati yakakura kudarika nzvimbo dzakapoteredza.Pasi pesimba remasimba akasiyana emhepo, zvimedu zvinoyangarara kubva pakati pepakati chubhu uye zvinosangana neinonamatira yakapfapfaidzwa kubva kupfuti yekupfapfaidza yakaiswa pakati pezasi.Vanobva vasungwa nehupfu inodonha kubva kumusoro uye vobva vagara kubva kunze kweiyo core chubhu kuti vagadzire chimiro chechidimbu.Inotenderera ichikwira nekudzika kuzadzisa chinangwa chekuita kuti zvimedu zvikure zvakaenzana.

3. Extrusion granulation nzira
Extrusion nzira parizvino ndiyo nzira huru yekumanikidza kugadzira granulation muindasitiri yehupfu yenyika yangu.Extrusion granulation midziyo inogona kukamurwa kuita vacuum tsvimbo granulator, imwe (kaviri) screw extrusion granulator, modhi stamping michina, plunger extruder, roller extruder, uye counter mixers zvinoenderana nemisimboti yavo yekushanda uye zvimiro.Gear granulator, etc. Mhando iyi yemidziyo inogona kushandiswa zvakanyanya muindasitiri yepetrochemical, organic chemical industry, yakanaka makemikari indasitiri, mushonga, chikafu, feed, fetiraiza uye mamwe minda.Iyi nzira ine zvakanakira kuchinjika kwakasimba, yakakura kubuda, yunifomu particle size, yakanaka particle simba, uye yakakwirira granulation rate.
