Izindaba

Embonini yensimbi eyigugu, isinyathelo ngasinye kusukela ekucwengisisweni kuya ekucutshungulweni sinezidingo eziphakeme kakhulu zokusebenza kwemishini, ukunemba, kanye nokuthembeka. Eminyakeni yamuva nje,ama-granulator e-vacuumziye zavela njengenkanyezi ekhulayo futhi kancane kancane zaba imishini ethandwayo embonini. Kunezizathu eziningi ezijulile ngemuva kwalokhu, ezihilela ubukhulu obuningi njengezimpawu zezinsimbi eziyigugu, izidingo zenqubo yokukhiqiza, kanye nokusebenza okuhle kakhulu kwemishini ngokwayo.

1. Ukuzivumelanisa nezimo zensimbi eyigugu nendawo yokuhlanza i-vacuum

Izinsimbi eziyigugu njengegolide, isiliva, iplatinum, njll. zinenani eliphezulu kakhulu kwezomnotho kanye nezakhiwo zamakhemikhali ezizinzile. Kodwa-ke, kusenengozi yokushiswa kwe-oxidation kanye nokungcola ezindaweni ezivamile njengezimo zokushisa eziphakeme kanye ne-aerobic. I-vacuum granulator ingadala indawo ecishe ibe yi-vacuum, ihlukanise ngempumelelo i-oxygen kanye namanye amagesi okungcola. Uma sithatha igolide njengesibonelo, enkambisweni evamile ye-granulation, izinga lokushisa eliphezulu lizobangela ukuthi ubuso bezinhlayiya zegolide zisabele nomoya-mpilo, kwakha ungqimba lwe-oxide oluncane kakhulu.

Nakuba lokhu kungase kubonakale kunomthelela omncane ekuhlanzekeni kwegolide, ekukhiqizweni okukhulu kanye nasemasimini afana ne-elekthronikhi kanye nobucwebe obudinga ubumsulwa obukhulu kakhulu, amaphutha ekhwalithi abangelwa yilokhu kuhlanzeka awamukeleki. Indawo yokuhlanzeka ngaphakathi kwe-vacuum granulator yehlisa okuqukethwe komoya-mpilo kube sezingeni eliphansi kakhulu, igwema kakhulu ukuhlanzeka kwezinsimbi eziyigugu ngesikhathi senqubo yokuhlanzeka, iqinisekisa ubumsulwa obukhulu bomkhiqizo, futhi ihlangabezana nezindinganiso eziqinile zomkhakha zekhwalithi yemikhiqizo yensimbi eyigugu.

2. Ukulawulwa okunembile kwenqubo yokuhlanganisa

Imboni yensimbi eyigugu inezidingo eziqinile neziqondile zosayizi wezinhlayiya, ukuma, kanye nobuningi bemikhiqizo. I-vacuum granulator, ngosizo lohlelo lokulawula oluthuthukisiwe lokuzenzakalela, ingalawula ngokunembile amapharamitha ahlukahlukene ngesikhathi senqubo ye-granulation. Ngokulawula izici ezibalulekile ezifana nesivinini sokugeleza kwezinto, izinga lokushisa, kanye nengcindezi, ukulawulwa okunembile kosayizi wezinhlayiya kungafinyelelwa. Ekukhiqizweni kwezinhlayiya zensimbi eyigugu zama-paste kagesi, kuyadingeka ukuthi ukusatshalaliswa kosayizi wezinhlayiya kube ngaphakathi kobubanzi obuncane kakhulu ukuqinisekisa ukufana nokuzinza kwe-paste ngesikhathi sokuphrinta, ukusha, kanye nezinye izinqubo.

 I-vacuum granulator ingakhiqiza izinhlayiya ezinobukhulu obuncane bokuphambuka kwezinhlayiya ngokusebenzisa izilungiselelo eziqondile zamapharamitha kanye nokusebenza okuzinzile, ihlangabezana nezidingo ezinembile kakhulu zemboni ye-elekthronikhi zezinto zensimbi eyigugu. Ngesikhathi esifanayo, ngokulungisa isikhunta se-granulation kanye namapharamitha enqubo, ukuma kwezinhlayiya kungashintshwa kalula, kusukela ku-spherical kuya ku-columnar, kanye nezinye izimo, ukuze kuhlangatshezwane nezidingo zezimo ezahlukene zokusetshenziswa kwezakhiwo zomzimba zezinhlayiya zensimbi eyigugu.

3. Ukugqamisa izinzuzo zokusebenza kahle kakhulu nokonga amandla

Ukulawulwa kwezindleko kubalulekile enqubweni yokukhiqizwa kwezinsimbi eziyigugu. Ukwakheka kwe-vacuum granulator kubheka ngokugcwele ukusebenza kahle kwamandla. Indawo yokuhlanza inciphisa izinga lokubila kwezinto, okuholela ekushiseni okuphansi okudingekayo enqubweni yokuhlanza izinsimbi, ngaleyo ndlela kunciphisa ukusetshenziswa kwamandla. Uma kuqhathaniswa nemishini yendabuko yokuhlanza izinsimbi, ama-vacuum granulators anganciphisa ukusetshenziswa kwamandla ngo-30% kuya ku-50% lapho ekhiqiza izinhlayiya zensimbi eziyigugu zekhwalithi efanayo nobuningi obufanayo.

Ekukhiqizweni okukhulu, ukonga izindleko zamandla okuqongelelwe isikhathi eside kukhulu kakhulu. Ngaphezu kwalokho, imodi yokukhiqiza eqhubekayo ye-vacuum granulator ithuthukise ukusebenza kahle kokukhiqiza. Imishini ingasebenza ngokuqhubekayo endaweni ezinzile ye-vacuum, iguqula njalo izinto zokusetshenziswa zensimbi eziyigugu zibe imikhiqizo ye-granular esezingeni eliphezulu, inciphise isikhathi sokungasebenzi kanye nesikhathi sokulungisa amaphutha enkambisweni yokukhiqiza, ithuthukise kakhulu umkhiqizo ngesikhathi seyunithi, futhi inciphise izindleko zokukhiqiza ngomkhiqizo weyunithi.

4. Ukusebenza kahle kwezemvelo nokuphepha

Izinkinga zokuvikelwa kwemvelo kanye nokuphepha azinakwa enqubweni yokukhiqizwa kwezinsimbi eziyigugu. Indawo evalwe nge-vacuum ye-vacuum granulator igwema ngempumelelo ukugcwala kothuli lwensimbi oluyigugu. Ezinqubweni zendabuko ze-granulation, ukukhishwa kothuli akugcini nje ngokubangela imfucuza yezinsimbi eziyigugu, kodwa futhi kuba usongo emvelweni kanye nempilo yabasebenzi. I-vacuum granulator ivala yonke inqubo ye-granulation ngaphakathi kohlelo lwe-vacuum, isusa amathuba okuvuza kothuli futhi ifinyelele ekukhiqizeni okuhlanzekile.

Ngesikhathi esifanayo, ngenxa yokunciphisa izingozi ezingaba khona ezibangelwa ukushisa okuphezulu, i-oxidation kanye nezinye izindlela zamakhemikhali, ukuphepha kwe-vacuum granulator ngesikhathi sokusebenza kuthuthuka kakhulu. Lapho kubhekene nama-isotope athile ensimbi ayigugu anemisebe noma anobuthi, indawo evalekile ye-vacuum granulator ingaqinisekisa kangcono ukuphepha kwabasebenzi kanye nendawo ezungezile, ivimbele ukuvuza nokusabalala kwezinto ezinemisebe noma ezinobuthi.

5. Zivumelanise nezidingo zokukhiqiza ezahlukahlukene

Imboni yensimbi eyigugu inezinhlobo eziningi zezicelo zemikhiqizo, kusukela kubucwebe obusezingeni eliphezulu kuya ezingxenyeni ze-elekthronikhi ezithuthukisiwe, kusukela emishinini yezokwelapha enembile kuya ezingxenyeni ezibalulekile embonini yezindiza. Amasimu ahlukene anezidingo ezahlukahlukene zokusebenza kanye nokucaciswa kwezinhlayiya zensimbi eyigugu. I-vacuum granulator, enekhono layo lokulungisa inqubo eliguquguqukayo, ingazivumelanisa ngokushesha nalezi zidingo zokukhiqiza ezahlukahlukene. Ngokushintsha ifomula yezinto ezibonakalayo, ukulungisa amapharamitha enqubo, kanye nokufaka esikhundleni sezimonyo ezahlukene ze-granulation, ama-vacuum granulators angakhiqiza imikhiqizo yezinhlayiya zensimbi eyigugu efanelekile ezimweni ezahlukene zohlelo lokusebenza.

Embonini yobucwebe, kuyadingeka ukukhiqiza izinhlayiya zensimbi eziyigugu eziyindilinga ezinobuso obubushelelezi nombala ofanayo wokufakwa; Emkhakheni wokupakisha nge-elekthronikhi, izinhlayiya zensimbi eziyigugu ezinobukhulu bezinhlayiya ezithile kanye nokugeleza okuhle ziyadingeka ukuqinisekisa ikhwalithi yokushisela. I-vacuum granulator ingahlangabezana kalula nalezi zidingo ezahlukene, inikeze ukwesekwa okuqinile kwezobuchwepheshe ekuthuthukisweni okuhlukahlukene kwemboni yensimbi eyigugu.

Ngokufigqiwe,ama-granulator e-vacuumsezibe yimishini ekhethwayo engenakuphikiswa embonini yensimbi eyigugu ngenxa yokuzivumelanisa kahle nezici zensimbi eyigugu, amakhono okulawula ama-granulation anembile, izinzuzo zokusebenza ezisebenza kahle nezonga amandla, ukusebenza kahle kwemvelo nokuphepha, kanye nokuzivumelanisa kabanzi nezidingo zokukhiqiza ezahlukahlukene. Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nokuthuthukiswa okuqhubekayo kwesidingo semboni, amathuba okusetshenziswa kwama-vacuum granulators embonini yensimbi eyigugu azoba banzi nakakhulu, edlala indima ebaluleke kakhulu ekukhuthazeni intuthuko yekhwalithi ephezulu yemboni yensimbi eyigugu.
