Zvigadziriso zvekuwedzera fetereza zvinowanzo sanganisira zvigadziriso zvekuwedzera zvinotenderera kaviri uye zvigadziriso zvekuwedzera zvinotenderera zvakatsetseka. Munguva yekugadzirisa fetereza dzakasanganiswa, zvigadziriso izvi zvinogona kuwedzera nitrogen elements zvichienderana nezvinodiwa, uye vamwe vanoshandisa urea senzvimbo yenitrogen elements, iyo inogona kupinza hunyoro mumhepo zviri nyore uye kukonzera kuti zvidimbu zvefetereza dzakasanganiswa zvinamire pamwe chete. Nokudaro, zvinowanzotaurwa kuti chigadziriso chekuwedzera chinotenderera kaviri ipureji yakaoma, iyo ine mhedzisiro iri nani pakugadzirisa granules dzezvinhu zvisina kugadzirwa zvine hunyoro husingasviki 10%. Pazvinhu zvakanyorova, tekinoroji inodiwa yekudzivirira kuomarara inofanira kuitwa. Kuti kuchengetwa kwegranules dzefetereza dzine hunyoro sezvinhu zvisina kugadzirwa zvefetereza dzakasanganiswa, zvakakosha kudzivirira kuomarara.
Nheyo uye zvinodiwa zvemvura zvemagranule ekugadzira mafetereza ekuwedzera granule
Musimboti wekushanda kwegranulator yekuwedzera ganda ndereupfu hwakaoma sezvinhu zvikuru. Kana zvinhu zvisina kusimba zvikadzvanywa, chikamu chezvikamu chinopwanywa, uye upfu hwakatsetseka hunozadza mipata iri pakati pezvikamu. Muchiitiko ichi, kana zvisungo zvemakemikari zvakasununguka pamusoro pechinhu chitsva hazvigone kuzadzwa nekukurumidza nemaatomu kana mamorekuru kubva mumhepo yakapoteredza, nzvimbo dzichangogadzirwa dzinosangana uye dzinoumba zvisungo zvakasimba zvekubatanidza. Pakubuda kweroller, ganda reroller rine gomo rakapesana, iro rinoburitswa kuita chimiro cheroller, uye zvikamu zvinoburitswa nedie yakatsetseka (rin'i) zviri columnar.Kubuda kwemvura muvhu kunoda hunyoro hushoma. Kana hunyoro hwacho hwakanyanya, zvakakosha kuwedzera sisitimu yekuomesa kune tekinoroji yekugadzirisa.
Mhinduro yekudzivirira migumisiro yakaipa yekunyudzwa kwemvura inobva munitrogen mukugadzirwa kwefetereza yakasanganiswa
Chinonyanya kukosha pakuumbwa kwefetereza yakasanganiswa inyaya yehuwandu hwemvura hunokonzerwa nemvura inonyudzwa nenitrogen source urea. Kana tichitarisa mashandiro emuchina, kutanga nekumhanya kwe "kupisa zvishoma nezvishoma" kwefetereza yakasanganiswa hakuwedzere kana huwandu hweammonium nitrate nepotassium chloride hwawedzera. Semuenzaniso, musanganiswa une 80% ammonium nitrate ne20% potassium chloride hautsvi, asi une musanganiswa we30% diatomaceous earth, 55% ammonium nitrate, uye 15% potassium chloride unogadzira "kupisa zvishoma nezvishoma" kwakasimba.
Zvidimbu zvefetereza zvine urea senitrogen zvine hygroscopicity yakanyanya uye zvinonyorovesa zvishoma; biuret neadducts zvinoumbwa zviri nyore kana tembiricha yakakwira; urea inonyungudika kana tembiricha yakwira, zvichikonzera kurasikirwa kweammonia.
Izvi zvinodiwa kuti mvura iwedzere kukwira inokonzerwa nemvura inosveta nitrogen. Kuderedza nitrogen source Kana calcium superphosphate iripo, phosphorus inonyungudika mumvura inoora; pakugadzira urea-common calcium superphosphate compound fertilizers, common superphosphate inofanira kucheneswa kare, senge ammoniation, iyo inogona kubvisa adducts. Gadzira, kana kuwedzera calcium magnesium phosphorus kuti ibvise free acid ye superphosphate, uye kushandura mvura inosveta kuita crystal water, kuvandudza mhando yechigadzirwa, kana kuwedzera ammonium sulfate, iyo inogona kuderedza hunyoro hwechigadzirwa chapera uye kusimbisa kuoma kwechigadzirwa chapera; kana paine chlorine. Kana ammonium yashandurwa, urea ne chlorine zvinoumba adduct, iyo inowedzera crystallization, iyo inoita kuti fertilizer inodziya zvakare ive nyore kukonzera agglomeration yechigadzirwa chapera panguva yekuchengetwa; saka, compound fertilizer ine urea se nitrogen source inofanira kunyatsotarisa maitiro ekuomesa nekutonhodza..Semuenzaniso, tembiricha yekuomesa haifanirwe kunge yakanyanya kukwira, nguva yekuomesa haifanirwe kunge yakareba, hunyoro hwakatarwa muchiyero chemhando yepamusoro hunofanira kuzadzikiswa, chiitiko chekunyunguduka panguva yekugadzira chinofanira kudzivirirwa, uye hapana kuchekwa kunofanirwa kuchengetwa panguva yekuchengetera.
Izvi ndizvo zvikonzero zvinoita kuti pave nehunyoro hwakawanda mukuita kwegranulation ye compound fertilizer granulator, izvo zvinokonzera kusimba kwevhu. Nzira huru yekudzivirira kusimba ndeyekushandisa system yekuomesa. Kugadzirisa zvinhu, kuwedzera zvinhu nezvimwe nzira, kuitira kuti pave nekugadzirisa uye kuchengetedzwa kwe compound fertilizer particles.
