Isigayo Sokugaya Esinomfutho Ophakeme we-HPGM
Isicelo
Kunezinhlobo eziningi zezinsizakusebenza zensimbi eShayina, kodwa izimfanelo zezinhlobo eziningi zezimbiwa azinhle, zihlukahlukene futhi zinhle. Ukuze kuxazululwe izinkinga ezivelele ezicini zomnotho, zobuchwepheshe kanye nokuvikelwa kwemvelo kwentuthuko yezimayini, amabhizinisi ezimayini zensimbi zasekhaya asungula, agaye futhi amunce imishini yokukhiqiza izimayini emisha nephumelelayo yangaphandle. Kulesi sizinda semakethe, i-HPGR iyimishini yokugaya esebenza kahle kakhulu eqale yacwaningwa futhi yaboniswa, futhi iqala ukusetshenziswa emabhizinisini ezimayini zensimbi zasekhaya. Futhi iyimishini yokukhiqiza imayini ethinteka kakhulu yimboni yezimayini zasekhaya. Kungashiwo ukuthi i-HPGR isetshenziswa kabanzi ezimayini zensimbi zasekhaya. I-HPGR ibilokhu isetshenziswa kabanzi ekhaya nakwamanye amazwe ekugayeni embonini yesimende, ukwakheka kwe-granulation embonini yamakhemikhali, kanye nokugaya kahle kwe-pellet ukwandisa indawo ethile ebusweni. Isetshenziselwa ukuchoboza insimbi yensimbi ukufeza izinhloso ezahlukene njengokwenza lula inqubo yokuchoboza, ukuchoboza kakhulu nokugaya okuncane, ukuthuthukisa umkhiqizo wesistimu, ukuthuthukisa umphumela wokugaya noma izinkomba zokuhlukanisa.
Isimiso Sokusebenza
I-HPGM series high pressure grinding roll iwuhlobo olusha lwemishini yokugaya eyonga amandla eklanywe ngesimiso sokugaya ungqimba lwezinto ezicindezelwe kakhulu. Iqukethe imiqulu emibili yokucindezela ejikeleza ngokuvumelana ngesivinini esiphansi. Enye iyi-roll engaguquki kanti enye iyi-roll ehambayo, zombili eziqhutshwa yinjini enamandla aphezulu. Izinto ezisetshenziswayo ziphakelwa ngokulinganayo ngaphezu kwemiqulu emibili, futhi ziqhutshwa njalo esikhaleni semiqulu nge-pressing roll. Ngemva kokufakwa ekucindezelweni okuphezulu okungu-50-300 MPa, ikhekhe lezinto eziqinile liyakhishwa emshinini. Ekhekheni lezinto ezikhishwe, ngaphezu kwengxenye ethile yemikhiqizo efanelekile, isakhiwo sangaphakathi sezinhlayiya zemikhiqizo engafaneleki sigcwele inani elikhulu lemifantu emincane ngenxa yokukhishwa kokucindezela okuphezulu, ukuze ikhono lokugaya lezinto lithuthuke kakhulu. Ngezinto ezisetshenziswayo ngemva kokukhishwa, ngemva kokuhlukana, ukuhlukanisa kanye nokuhlola, izinto ezincane ezingaphansi kuka-0.8 mm zingafinyelela cishe ku-30%, kanti izinto ezingaphansi kuka-5 mm zingafinyelela ngaphezu kuka-80%. Ngakho-ke, enkambisweni yokugaya eyengeziwe, ukusetshenziswa kwamandla okugaya kungancishiswa kakhulu, ukuze amandla okukhiqiza emishini yokugaya asebenze ngokugcwele, ngokuvamile amandla ohlelo lokugaya ibhola angandiswa ngo-20% ~ 50%, futhi ukusetshenziswa kwamandla okuphelele kungancishiswa ngo-30% ~ 50% noma ngaphezulu.
Izinzuzo Zomkhiqizo
■Umklamo wokucindezela oqhubekayo uqinisekisa ukucindezela okubushelelezi phakathi kwemiqulu futhi uqinisekisa umphumela wokuchoboza.
■Ukulungiswa kokuphambuka okuzenzakalelayo, kungalungisa ngokushesha igebe lokugoqa ukuqinisekisa ukuthi imishini ibushelelezi.
■Uhlelo lokuhlukanisa imiphetho lunciphisa umphumela wemiphumela yomphetho emphumeleni wokuchoboza.
■Inezipikili ze-carbide eziqinisiwe, isikhathi eside senkonzo, kulula ukuzilungisa, futhi zingashintshwa.
■Ibhange le-valve lisebenzisa izingxenye ezingenisiwe, futhi uhlelo lwe-hydraulic lunomklamo ofanele kanye nokuthembeka okuhle.
