Iigranulator ze-extrusion zesichumiso eziqhelekileyo ziquka i-double-roll extrusion granulators kunye ne-flat (ring) i-die extrusion granulators.Ebudeni bokulungiswa kwezichumisi ezihlanganisiweyo, ezi granulators zisenokwandisa izinto zenitrogen ngokweemfuno, kwaye ezinye zisebenzisa iurea njengomthombo wezinto zenitrogen, ezinokufunxa lula ukufuma emoyeni zize zibangele ukuba amasuntswana esichumiso ahlangane.Ngoko ke, kudla ngokuthiwa i-double-roll extrusion granulator yi-powder granulator eyomileyo, enefuthe elingcono ekuqhubeni iigranules zezixhobo eziluhlaza kunye nomswakama ongaphantsi kwe-10%.Kwizinto ezimanzi, iteknoloji efunekayo yokulwa nokuqina kufuneka iqhutywe.Ukugcina iigranules zesichumisi eziqulethe ukufuma njengezinto ezikrwada zezichumisi ezihlanganisiweyo, kuyimfuneko ukuphepha ukuqina.
Umgaqo kunye neemfuneko zamanzi zesichumiso esihlanganisiweyo se-granulator ye-granulator yokucubungula iigranule
Umgaqo wokusebenza wegranulator ye-extrusion ubukhulu becala ngumgubo owomileyo njengeyona nto iphambili ekrwada.Xa i-brittle material icinezelwe, inxalenye yeengqungquthela iyachithwa, kwaye i-powder ecocekileyo igcwalisa izikhewu phakathi kweengqungquthela.Kule meko, ukuba iibhondi zeekhemikhali zamahhala kwindawo esanda kuveliswa ayinakuhluthwa ngokukhawuleza ngee-athomu okanye iimolekyuli ezivela kwi-atmosfera ejikelezileyo, iindawo ezisandul 'ukuveliswa zidibana kunye kwaye zenze amabhondi anamandla okudibanisa.Kwi-extrusion ye-roller, ulusu lwe-roller lune-groove e-spherical ephikisanayo, ekhutshwe kwi-spherical shape, kwaye amaqhekeza akhutshwe yi-flat (ring) afa yi-columnar.I-Extrusion granulation ifuna isiqulatho sokufuma esisezantsi.Ukuba umswakama uphezulu kakhulu, kuyimfuneko yokongeza inkqubo yokomisa kwi-teknoloji yokucubungula.
Isisombululo kwiziphumo ezibi zomthombo wenitrogen wohlobo lokufunxa ukufuma kwinkqubo ye-compound yesichumiso segranulation
I-crux ye-compaction kwinkqubo ye-compound yesichumiso se-granulation ininzi isiqulatho samanzi esiphezulu esibangelwa ngumthombo we-nitrogen urea efunxa amanzi.Ukuthetha ngoomatshini, ukuqaliswa kunye nesantya "sokutshisa ngokukhawuleza" kwezichumisi ezixubileyo akunyuki ngokunyuka kwe-ammonium nitrate kunye nomxholo we-potassium chloride.Ngokomzekelo, umxube oqukethe i-80% ye-ammonium nitrate kunye ne-20% ye-potassium chloride ayitshisi, kodwa iqulethe umxube we-30% we-diatomaceous earth, i-55% ye-ammonium nitrate, kunye ne-15% ye-potassium chloride ivelisa "ukutshisa okucothayo".
Amasuntswana esichumiso esidityanisiweyo kunye ne-urea njengomthombo wenitrogen ane-hygroscopicity ephezulu kunye nenqanaba eliphantsi lokuthambisa;i-biuret kunye ne-adducts zenziwe ngokulula xa ubushushu buphezulu;I-urea iya kwenziwa nge-hydrolyzed xa ubushushu buphezulu, okukhokelela ekulahlekeni kwe-ammonia.
Oku kuyimfuneko ukusombulula umthamo wamanzi aphezulu obangelwa ngumthombo wenitrogen ofunxa amanzi.Ukunciphisa umthombo wenitrogen Xa icalcium superphosphate ikhona, iphosphorus enyibilikayo emanzini iya kuthotywa;xa uvelisa urea-eqhelekileyo calcium superphosphate compound izichumiso, superphosphate eqhelekileyo kufuneka pretreated, ezifana ammoniation, nto leyo enokuphelisa i-adducts Ukuvelisa, okanye ukongeza calcium magnesium phosphorus ukuba neutralize i-asidi simahla superphosphate, nokuguqula amanzi simahla ibe yikristale amanzi, ukuphucula imveliso. umgangatho, okanye ungeze i-ammonium sulfate, enokunciphisa umswakama wemveliso egqityiweyo kwaye iqinise ubulukhuni bemveliso egqityiweyo;xa kukho i-chlorine Xa i-ammonium iguqulwa, i-urea kunye neklorini zenza i-adduct, eyandisa i-crystallization, eyenza isichumisi sokuvuselela lula ukubangela i-agglomeration yemveliso egqityiweyo ngexesha lokugcinwa;ke ngoko, isichumiso esixutywe ne-urea njengomthombo wenitrogen kufuneka sihlawule ingqalelo ekhethekileyo kwinkqubo yokomisa kunye nokupholisa.Umzekelo, ubushushu bokomisa akufuneki bube phezulu kakhulu, ixesha lokumisa alifanele libe lide kakhulu, umthamo wokufuma ochazwe kumgangatho womgangatho kufuneka udityaniswe, into enyibilikayo ngexesha lenkqubo yokuvelisa kufuneka igwenywe, kwaye akufuneki kugcinwe i-caking. ngexesha lenkqubo yokugcina.
Ezi zingentla zizizathu zokufuma okuphezulu kwinkqubo ye-granulation ye-compound fertilizer granulator, ebangela ukuxinwa.Indlela ephambili yokuphepha ukuxinwa kukusetyenziswa kwenkqubo yokomisa.Ukulungiswa kwangaphambili kwezinto, ukongezwa kwezinto kunye nezinye iindlela, ukuze kuqondwe ukusetyenzwa kunye nokugcinwa okungonakaliyo kwamasuntswana omanyolo adibeneyo.
