I-HPGM High Pressure Grinding Mill
Isicelo
Kunezinhlobo eziningi zemithombo yensimbi yensimbi eShayina, kodwa izimfanelo zezinhlobo eziningi zamaminerali zimbi, ziyahlukahluka futhi zinhle. Ukuze kuxazululwe izinkinga ezisasele emkhakheni wezomnotho, ezobuchwepheshe kanye nokuvikelwa kwemvelo ekuthuthukisweni kwezimayini, amabhizinisi asekhaya ezimayini zensimbi angenisa ngenkuthalo, agaya futhi amunca amathuluzi angaphandle asebenzayo okukhiqiza izimayini. Kulesi sizinda semakethe, i-HPGR iyimishini yokugaya esebenza kahle kakhulu eyacwaningwa kuqala futhi yaboniswa, futhi iqala ukusetshenziswa kumabhizinisi asekhaya ezimayini zensimbi. Kuphinde kube yimishini yokukhiqiza imayini ethinteka kakhulu imboni yezimayini yasekhaya. Kungashiwo ukuthi i-HPGR isetshenziswa kakhulu ezimayini zensimbi zasekhaya. I-HPGR isetshenziswe kakhulu ekhaya nakwamanye amazwe ekugayeni embonini kasimende, i-granulation embonini yamakhemikhali, kanye nokugaya kahle kwe-pellet ukwandisa indawo ethile. Isetshenziselwa ukuchotshozwa kwensimbi yensimbi ukuze kuzuzwe izinhloso ezehlukene ezifana nokwenza lula inqubo yokuchotshozwa, ukuchotshozwa okwengeziwe nokugaya kancane, ukuthuthukisa ukukhiqiza kwesistimu, ukuthuthukisa umphumela wokugaya noma izinkomba zokuhlukanisa.
Isimiso Sokusebenza
I-HPGM series high pressure grinding roll iwuhlobo olusha lwemishini yokugaya eyonga amandla eklanywe ngomgomo wokupondwa kwengqimba yezinto ezinomfutho ophezulu. Iqukethe amaroli amabili acindezelayo azungezisayo ngokuhambisanayo ngesivinini esiphansi. Eyodwa iyiroli emile kanti enye iyiroli eligudlukayo, womabili ashayelwa yinjini enamandla amakhulu. Izinto ezisetshenziswayo zondliwa ngokulinganayo ukusuka ngenhla kwemiqulu emibili, futhi ziqhutshwa ngokuqhubekayo kugebe le-roll ngomqulu ocindezelayo. Ngemuva kokuba ngaphansi kwengcindezi ephezulu ye-50-300 MPa, ikhekhe lezinto eziminyene liyakhishwa emshinini. Ekhekheni lezinto ezikhiqiziwe, ngaphezu kwengxenye ethile yemikhiqizo efanelekayo, isakhiwo sangaphakathi sezinhlayiya zemikhiqizo engafaneleki sigcwaliswa ngenani elikhulu lokuqhekeka okuncane ngenxa ye-extrusion ephezulu yokucindezela, ukuze ikhono lokugaya impahla ligcwaliswe. ngcono kakhulu. Okwezinto ezisetshenziswayo ngemuva kokukhishwa, ngemuva kokuhlukana, ukuhlukaniswa nokuhlolwa, izinto ezinhle ezingaphansi kuka-0.8 mm zingafinyelela cishe ku-30%, futhi izinto ezingaphansi kuka-5 mm zingafinyelela ngaphezu kwama-80%. Ngakho-ke, enqubweni eyengeziwe yokugaya, ukusetshenziswa kwamandla okugaya kungancishiswa kakhulu, ukuze umthamo wokukhiqiza wemishini yokugaya usetshenziswe ngokugcwele, ngokuvamile umthamo wesistimu yokugaya ibhola ungakhuphuka ngo-20% ~ 50. %, futhi ukusetshenziswa kwamandla okuphelele kungancishiswa ngo-30% ~ 50% noma ngaphezulu.
Izinzuzo Zomkhiqizo
■ Idizayini yengcindezi eqhubekayo iqinisekisa ingcindezi ebushelelezi phakathi kwamaroli futhi iqinisekisa umphumela wokuchoboza.
■ Ukulungiswa kokuchezuka okuzenzakalelayo, kungalungisa ngokushesha igebe le-roll ukuze kuqinisekiswe ukushelela kwemishini.
■ Uhlelo lokuhlukanisa unqenqema lunciphisa umphumela wemiphumela enqenqemeni kumphumela wokuchoboza.
■Ngezigxivizo ze-carbide zikasimende, impilo ende yesevisi, ukunakekelwa okulula, nokushintshwa.
■ Ibhange lama-valve lamukela izingxenye eziphuma kwamanye amazwe, futhi uhlelo olusebenzisa amanzi amaningi lunomklamo onengqondo nokwethembeka okuhle.
