I-HPGR vs Ama-Ball Mills: Yibuphi Ubuchwepheshe Bokugaya Obukhulisa Ukusebenza Kahle Futhi Bunciphise Izindleko Ezimayini?

I-HPGR vs Ama-Ball Mills: Ukuqhathanisa Okuphelele Kokusebenza Kahle Kokucubungula Amaminerali

Ekucutshungulweni kwezimbiwa kwanamuhla, ukukhetha ubuchwepheshe bokugaya obufanele kubalulekile ekukhuliseni umkhiqizo kanye nokunciphisa izindleko zokusebenza. Phakathi kwezinketho ezisetshenziswa kakhulu yi-High Pressure Grinding Rolls (HPGR) kanye ne-Ball Mills. Kodwa iyiphi enikeza ukusebenza kahle okungcono, ukukhiqiza okuphezulu, kanye nokusetshenziswa kwamandla okuphansi?

Ukuqonda Izisekelo ze-HPGR kanye ne-Ball Mills

Ama-Ball Mills abe ngumgogodla wobuchwepheshe bokugaya amashumi eminyaka. Asebenza ngokujikeleza isilinda esigcwele amabhola ensimbi, agqube i-ore ngokusebenzisa umthelela kanye nokuwa. Aziwa ngokuguquguquka kwawo, ama-ball mill ayakwazi ukugaya izinto eziningi ezahlukene, okwenza kube kuhle kakhulu ekukhiqizweni kosayizi wezinhlayiya ezincane kuma-ball mill.

Ama-High Pressure Grinding Rolls (HPGR), ngakolunye uhlangothi, asebenzisa ama-counter-rolling rolls amabili ukuze acindezele i-ore ngaphansi komfutho ophezulu, okwenza kube nemifantu emincane ethuthukisa izinqubo ezingezansi njengokugeleza kanye nokuntanta. Izinzuzo ze-HPGR ekumbeni zifaka phakathi ukusatshalaliswa kosayizi wezinhlayiya ezifanayo, ukukhululwa okuthuthukisiwe kwamaminerali abalulekile, kanye nokusetshenziswa okuvame ukuba phezulu kune-ball mill.

Ukusetshenziswa Kahle Kwamandla: I-HPGR Iyahola

Ukusetshenziswa kwamandla kuyisici esibalulekile ekugayweni kwamaminerali kwanamuhla. Izifundo kanye nedatha yezimboni zibonisa ukuthi ukusebenza kahle kwamandla e-HPGR kuma-ore aqinile kunganciphisa ukusetshenziswa kwamandla ngo-30-40% uma kuqhathaniswa nemishini yokugaya amabhola yendabuko. Lokhu kuholela ekongeni izindleko okukhulu, okwenza ama-HPGR abe yisinqumo esihle kakhulu sokunciphisa izindleko zamandla ekugayweni kwamaminerali.

Ukusabalala Kokugeleza Nosayizi Wezinhlayiyana

Ama-ball mill ahamba phambili ekukhiqizeni osayizi bezinhlayiya ezincane kakhulu, okubalulekile ezinqubweni ezithile ze-metallurgical. Kodwa-ke, ama-HPGR ahlinzeka ngokusatshalaliswa kosayizi wezinhlayiya ezifanayo kanye nokukhululwa kwezimbiwa okuthuthukisiwe. Ukusebenza kwawo okuqhubekayo kanye nezidingo zokucindezela okuphansi kokugaya kuvumela amasu okwenza ngcono ukuphuma kwamandla okuthuthukisa ukusebenza kahle kwenqubo iyonke.

Izinto Okufanele Zicatshangelwe Ekunakekeleni Nokusebenza

Izigayo zebhola zilula ngokwemishini kodwa zidinga ukulungiswa njalo, okuhlanganisa ama-liners kanye nokushintsha imidiya yokugaya. Ama-HPGR, nakuba ekuqaleni edinga imali eningi, ngokuvamile anezindleko zokuguguleka eziphansi kanye nesikhathi esincishisiwe sokungasebenzi ngenxa yezindawo zawo zokugoqa eziqinile kanye nendlela yokugaya esebenza kahle. Lezi zici zenza ama-HPGR akhange ukusetshenziswa kwe-HPGR kwezimboni ekucutshungulweni kwamaminerali.

Ukukhetha Ubuchwepheshe Bokugaya Obufanele

Ukukhetha phakathi kwe-HPGR kanye nemishini yokugaya ibhola kuncike ezintweni eziningana: ubulukhuni bensimbi, isikali sokukhiqiza, izindleko zamandla, kanye nezidingo zokucubungula ezansi. Kuma-ore aqinile kanye nemisebenzi emikhulu, ama-HPGR avame ukuletha ukusebenza kahle okuphezulu kanye nokonga izindleko. Imishini yokugaya ibhola ihlala iyisinqumo esithembekile sezinhlelo zokusebenza ezidinga ubukhulu bezinhlayiya ezincane kakhulu, ezinikeza ukuguquguquka nokusebenza okuqinisekisiwe.

Abaqhubi bezimayini abafuna ukuthuthukisa amasekethe okugaya ukuze bakhiqize kakhulu kufanele bahlaziye ngokucophelela izici zensimbi kanye nezidingo zenqubo ukuze banqume ukuthi yibuphi ubuchwepheshe obufanelana kahle nokusebenza kwabo.

Isiphetho

Kokubili ama-HPGR kanye nama-ball mill anendima ebalulekile ekucutshungulweni kwezimbiwa kwanamuhla. Kodwa-ke, lapho ukusebenza kahle kanye nokusebenza kahle kwezindleko kuyizinto eziza kuqala, ubuchwepheshe be-HPGR buvelela kakhulu. Ngokusebenzisa ukuqonda kokuqhathanisa ukusebenza kahle kwe-HPGR vs Ball Mills, izinkampani zezimayini zinganciphisa ukusetshenziswa kwamandla, zithuthukise umkhiqizo, futhi zikhulise inzuzo.
