I-HPGR High Pressure Grinding Mill
Isicelo
I-single-drive high-high pressure rolling roll iklanyelwe ngokukhethekile ukugaya ngaphambili izinsimbi zikasimende, imfucumfucu yamaminerali, izinsimbi zensimbi njalo njalo zibe yizinhlamvana ezincane, ukuchoboza amaminerali ensimbi (insimbi, i-manganese ores, insimbi yethusi). , i-lead-zinc ore, i-vanadium ores nezinye) kanye nokugaya amaminerali angeyona insimbi (amalahle gangues, i-feldspar, i-nepheline, i-dolomite, i-limestone, i-quartz, njll.) ibe yimpushana.
Isakhiwo & Isimiso Sokusebenza
Umdwebo Wesimiso Sokusebenza
Iroli yokugaya yedrayivu eyodwa ephezulu isebenzisa umgomo wokugaya we-aggregate extrusion.Enye i-stationary roll kanti enye i-movable roll.Imiqulu emibili izungeza ngokuphambene ngesivinini esifanayo.Izinto ezisetshenziswayo zingena zisuka ekuvuleni okuphakelayo okuphezulu, futhi zigaywe ngenxa ye-extrusion ngokucindezela okukhulu esikhaleni semiqulu emibili, futhi zikhishwe phansi.
Shayela ingxenye
Kudingeka i-motor drive eyodwa kuphela, amandla adluliswa esuka kuroli omile aye kugiya olugudlukayo ngohlelo lwegiya, ukuze amaroli amabili ahambisane ngokugcwele ngaphandle kokungqubuzana kokuslayida.Umsebenzi wonke usetshenziselwa ukukhishwa kwezinto ezibonakalayo, futhi izinga lokusebenzisa amandla liphezulu, okonga u-45% kagesi uma kuqhathaniswa nomqulu ovamile wokugaya umfutho ophezulu.
Isistimu yokufaka ingcindezi
Isistimu yokufaka ingcindezi ye-spring mechanical ehlanganisiwe yenza umqulu osusekayo ugweme ngokuguquguquka.Uma kungena insimbi yangaphandle, uhlelo lokusebenzisa ingcindezi yasentwasahlobo luhlehla ngqo futhi luphendule ngesikhathi, luqinisekise ukuthi izinga lokusebenza liphezulu njengo-95%;kuyilapho umqulu ovamile wokugaya umfutho ophezulu wenza ukugwema, uwoyela we-hydraulic udinga ukukhishwa ngepayipi ukuze unciphise ingcindezi.Isenzo sibambezelekile, okungase kudale umonakalo endaweni eqengqelekayo noma ukungasebenzi kahle kwesistimu ye-hydraulic.
Roll surface
Ingaphezulu le-roll libheke phezulu lishiselwe ngezinto zokushisela ezingezwani nengxubevange, futhi ubulukhuni bungafinyelela ku-HRC58-65;ukucindezela kulungiswa ngokuzenzakalelayo ngempahla, engafezi nje kuphela inhloso yokugaya, kodwa futhi ivikela ubuso be-roll;umqulu ogudlukayo kanye nomqulu onganyakazi kusebenza ngokuhambisanayo ngaphandle kokushwibilika.Ngakho-ke, impilo yesevisi ye-roll surface iphakeme kakhulu kune-roll evamile yokugaya ingcindezi ephezulu.
Izici Eziyinhloko Zobuchwepheshe
■ Ukusebenza Ngekhono Eliphezulu.Uma kuqhathaniswa nemishini yokuchoboza yendabuko, amandla okucubungula akhuphuka ngo-40 - 50%.Umthamo wokucubungula we-PGM1040 ungafinyelela cishe ku-50 - 100 t/h, ngamandla angu-90kw kuphela.
■ Ukusebenzisa Amandla Aphansi.Njengokwendlela yokushayela eyodwa, idinga injini eyodwa ukuyishayela.Ukusetshenziswa kwamandla kuphansi kakhulu.Uma kuqhathaniswa ne-HPGR ye-double drive evamile, inganciphisa ukusetshenziswa kwamandla ngo-20~30%.
■Ikhwalithi Enhle Yokumelana Nokugqoka.Ngokushayela kwemoto eyodwa kuphela, ukusebenza kokuvumelanisa kwemiqulu emibili kuhle kakhulu.Ngezindawo zokushisela ezingagugi, ama-roll anekhwalithi enhle engagugi futhi angagcinwa kalula.
■Izinga Lokusebenza Eliphezulu: ≥ 95%.Ngokuklama kwesayensi, imishini ingacindezelwa yiqembu le-spring spring pressure.Ingcindezi yokusebenza ingalungiswa ngokuzenzakalelayo njengokucindezela kweqembu lasentwasahlobo.Alikho iphuzu lokungasebenzi kahle.
■ I-Automation ephezulu kanye nokulungiswa okulula.Ngaphandle kwesistimu ye-hydraulic, kunezinga eliphansi lokungasebenzi kahle.
■Indawo ewugqinsi ingaphezulu eshiselwe ngezinto zokushisela ezingagugi, ezinokuqina okuphezulu nokungagugi kahle;Ukucindezela entwasahlobo kuvela emandleni okusabela ezinto ezibonakalayo, futhi ingcindezi ihlale ilinganisela, engafezi nje injongo yokuchotshozwa, kodwa futhi ivikela ubuso be-roll;umqulu ogudlukayo kanye neroli elimile kunemeshi futhi ishayelwa isistimu yegiya, futhi isivinini sivunyelaniswa ngokuphelele, ngaleyo ndlela kugwenywa ukungqubuzana kokuslayida phakathi kwempahla nendawo eqengqelekayo.Ngakho-ke, impilo yesevisi iphakeme kakhulu kunaleyo ye-double drive HPGR.
■ Isakhiwo esihlangene nendawo encane yaphansi.
