Dị ka fatịlaịza a na-ejikarị eme ihe, urea nwere nchegbu maka mmepe ya.Ka ọ dị ugbu a, a na-ekewa urea n'ahịa n'ime nnukwu ihe na obere ihe.N'ikwu okwu n'ozuzu, urea nwere dayameta urughuru karịa 2mm ka a na-akpọ nnukwu urea granular.Ihe dị iche na urughuru size bụ n'ihi na ihe dị iche na granulation usoro na akụrụngwa mgbe urea mmepụta na factory.Kedu ihe dị iche n'etiti nnukwu urea granular na obere urea granular?
Nke mbụ, myirịta dị n'etiti nnukwu na obere urea granular bụ na ihe ha na-arụ ọrụ bụ molecule urea na-agbaze ngwa ngwa nke nwere nitrogen ọdịnaya nke 46%.Site n'echiche physics, naanị ihe dị iche bụ nha nha.Urea buru ibu nwere obere uzuzu uzuzu, ike mkpakọ dị elu, mmiri dị mma, enwere ike ibufe ya n'ọtụtụ, ọ dịghị mfe ịgbaji na agglomerate, ọ dịkwa mma maka nhazi nke mechanized.
Nke abuo, site n'echiche nke fatịlaịza, akụkụ elu nke obere urea urea buru ibu, ebe kọntaktị na mmiri na ala na-ebuwanye ibu mgbe etinyere ya, mgbasa na ntọhapụ na-adị ngwa ngwa.Mgbasa na ntọhapụ nke nnukwu urughuru urea n'ime ala dị ntakịrị nwayọọ.N'ozuzu, e nwere obere ihe dị iche na fatịlaịza irè n'etiti abụọ.
A na-egosipụta ọdịiche a na usoro ntinye.Dịka ọmụmaatụ, na usoro nke akwa akwa, mmetụta fatịlaịza nke obere urea granular dị ngwa ngwa karịa nke nnukwu urea granular.Site n'echiche nke ọnwụ, ọnwụ nke nnukwu urea granular dị obere karịa nke obere urea granular, na ọdịnaya nke diurea na nnukwu urea granular dị ala, nke bara uru maka ihe ọkụkụ.
N'aka nke ọzọ, maka mmịnye na itinye ihe ọkụkụ n'ọrụ, urea bụ nitrogen molecular, nke ihe ọkụkụ na-etinye ya ozugbo na ntakịrị ntakịrị, enwere ike ịmịnye ya naanị n'ọtụtụ buru ibu mgbe agbanwere ya na ammonium nitrogen n'ime ala.Ya mere, n'agbanyeghị nha urea, topdressing bụ ọtụtụ ụbọchị tupu ammonium bicarbonate.Na mgbakwunye, nha nha nke nnukwu urea granular yiri nke diammonium phosphate, yabụ enwere ike ịgwakọta nnukwu urea granular na diammonium phosphate dị ka fatịlaịza ntọala, ọ dịkwa mma ka ị ghara iji nnukwu urea granular maka akwa akwa.
Ọnụego mgbasa nke nnukwu urea granular na-eji nwayọ nwayọ, nke dabara maka fatịlaịza ntọala, ọ bụghị maka akwa akwa na ịkwanye fatịlaịza.Ogo urughuru ya dabara na nke dimmonium phosphate na enwere ike iji ya mee ihe maka fatịlaịza ngwakọta agwakọta.Ekwesiri ighota ebe a na enweghi ike igwakota urea buru ibu na ammonium nitrate, sodium nitrate, ammonium bicarbonate na fatịlaịza hygroscopic ndị ọzọ.
Site na fatịlaịza ule nke nnukwu granular urea na nkịtị obere granular urea na owu, mmepụta mmetụta nke nnukwu granular urea na owu na-egosi na aku na uba àgwà, mkpụrụ na mmepụta uru nke nnukwu granular urea dị mma karịa obere granular urea, nke nwere ike ịkwalite Owu siri ike ma gbochie ịka nká nke owu na-ebelata ọnụego mwụda nke mkpụrụ osisi owu.
