Sefetireza inowanzo shandiswa, urea yanga ichinetsekana nekukura kwayo. Parizvino, urea pamusika yakakamurwa kuita zvidimbu zvakakura uye zvidiki zvidiki. Kazhinji kutaura, urea ine chidimbu dhayamita yakakura kupfuura 2mm inonzi huru granular urea. Musiyano muhukuru hwechikamu unokonzerwa nemusiyano wegranulation process uye zvishandiso mushure mekugadzirwa kweurea mufekitori. Ndeupi musiyano uripo pakati pehombe granular urea uye diki granular urea?
Chekutanga, kufanana pakati pehombe nediki granular urea ndeyekuti yavo inoshanda inyunguruke inonyungudika inokurumidza kuita urea molecule ine nitrogen inokwana 46%. Kubva pamaonero efizikisi, mutsauko chete ndiwo saizi yechidimbu. Huru-grained urea ine yakaderera huruva yemukati, yakakwirira yekumanikidza simba, yakanaka fluidity, inogona kutakurwa yakawanda, haisi nyore kuputsika uye agglomerate, uye inokodzera kugadzirwa nemichina.
Chechipiri, kubva pamaonero ekuberekesa, nzvimbo yepasi yezvimedu zvidiki urea yakakura, nzvimbo yekubatana nemvura nevhu yakakura mushure mekushandisa, uye kunyungudika nekumhanyisa kuburitsa kunokurumidza. Kunyungudika nekuburitswa kwechikamu chikuru cheurea muvhu kunononoka zvishoma. Kazhinji, pane musiyano mudiki mukubudirira kwefetereza pakati pezviviri izvi.
Musiyano uyu unoratidzwa munzira yekushandisa. Semuenzaniso, mukugadzirisa kwepamusoro, iyo fetireza mhedzisiro yediki granular urea inokurumidza kukurumidza kupfuura iyo yakakura granular urea. Kubva pakuona kwekurasikirwa, kurasikirwa kwegranular urea yakakura ishoma pane iyo yediki granular urea, uye zviri mukati diurea mune yakakura granular urea yakaderera, iyo inobatsira kune zvirimwa.
Nekune rumwe rutivi, pakutorwa nekushandiswa kwembesa, urea is molecular nitrogen, iyo inotorwa zvakananga nezvirimwa muchidimbu chiduku, uye inogona kungotorwa muhuwandu hwakawanda mushure mekushandurwa kuita ammonium nitrogen muvhu. Naizvozvo, zvisinei nehukuru hweurea, kupfekedza kwepamusoro mazuva akati wandei pamberi peammonium bicarbonate. Uye zvakare, iyo particle size yegranular urea yakakura yakafanana neye diammonium phosphate, saka yakakura granular urea inogona kusanganiswa nediammonium phosphate sechigadziko fetiraiza, uye zviri nani kusashandisa yakakura granular urea yekupfeka yepamusoro.
Kunyungudika kwehombe granular urea inononoka zvishoma, iyo inokodzera fetiraiza yepasi, kwete yekupfekedza kumusoro uye kufambisa fetiraiza. Hukuru hwayo hunoenderana neiyo diammonium phosphate uye inogona kushandiswa sechinhu chemusanganiswa wefetiraiza. Izvo zvinofanirwa kucherechedzwa pano kuti yakakura granular urea haigone kusanganiswa neammonium nitrate, sodium nitrate, ammonium bicarbonate uye mamwe mafetiraiza ehygroscopic.
Kuburikidza nekuyedzwa kwefetireza yehombe yegranular urea uye yakajairwa diki granular urea padonje, kugadzirwa kwehombe granular urea padonje inoratidza kuti hupfumi, goho uye kukosha kwekubuda kwehombe granular urea zviri nani pane diki granular urea, inogona kusimudzira kukura kwakadzikama kwekotoni uye kudzivirira Kukurumidza kuchembera kwekotoni kunoderedza chiyero chekudurura chekotoni buds.
