Yiziphi izinyathelo zokusebenza ze-high pressure grinding rolls

I-High pressure grinding rolls (HPGR) iwuhlobo lwempahla esetshenziswayo esetshenziswa embonini yezimayini kanye nokucubungula amaminerali. Zenzelwe ukunciphisa usayizi wezinhlayiya ngokuzicindezela futhi uzichoboze phakathi kwemiqulu emibili ephikisanayo enegebe elincane phakathi kwazo. Ama-HPGR ajwayele ukusetshenziselwa ukucubungula ama-ore aqinile futhi abrasive.

Izinyathelo zokusebenza ze-HPGRs

Okuphakelayo Kwempahla Isingeniso: Insimbi noma impahla ezocutshungulwa yethulwa esikhaleni esiphakathi kwamaroli amabili. Lokhu okuphakelayo kungahluka kakhulu ngokuya ngosayizi, ubulukhuni, kanye nokuqukethwe komswakamo.

Comminution: Njengoba amaroli ezungeza, enza ingcindezi ephezulu kokuphakelayo. Lokhu kucindezela kubangela ukuba izinhlayiya ziphuke futhi ziwohloke, okuholela ekuncipheni kosayizi wezinhlayiyana. Izinto ezibonakalayo ngokuyinhloko zichotshozwa ngenhlanganisela yokucindezelwa nokuqhekeka kwezinhlayiyana.

Ukwakheka Kombhede Wezinhlayiyana: Izinto ezichotshoziwe zakha umbhede phakathi kwamaroli. Umbhede wezinhlayiyana usebenza njenge-cushion esiza ukusabalalisa ingcindezi ngokulinganayo futhi uvimbele ukuguga ngokweqile kuma-rolls.

Ukukhipha: Uma okokusebenza sekwenziwe ngokwanele, kuyaphuma ku-HPGR ngegebe eliphakathi kwamaroli. Umkhiqizo, ovame ukubizwa ngokuthi "ama-flakes," "ama-chips," noma "amakhekhe," ngokuvamile unokusabalalisa kosayizi wezinhlayiyana okufana kakhulu uma kuqhathaniswa nezindlela zokugaya zendabuko.

Ukujikeleziswa kabusha: Kwezinye izimo, ingxenye yomkhiqizo ingase idluliselwe emuva ku-HPGR ukuze iqhubeke nokugaywa. Lokhu kungasiza ukufeza ukusatshalaliswa kosayizi wezinhlayiyana noma ukuthuthukisa ukusebenza kahle okuphelele.

Ama-HPGR anikeza izinzuzo ezimbalwa kunezindlela zokugaya zendabuko, njengezigayo zebhola kanye nezigayo ze-SAG:

• Ukusebenza Kahle Kwezamandla: Ama-HPGR ngokuvamile adinga amandla amancane ngethani ngalinye lezinto ezichotshoziwe uma kuqhathaniswa nezigayo ezivamile zokugaya.
• Ukusabalalisa Usayizi Wezinhlayiyana: Ama-HPGR angakhiqiza ukufana okufanayo nokusabalalisa usayizi wezinhlayiyana ezinhle, okungaba yinzuzo ezinqubweni ezingezansi zomfula njengokuntanta noma ukuleaching.
• Ukusetshenziswa Kwamanzi Okuncishisiwe: Ama-HPGR angasebenza ngokusetshenziswa kwamanzi okuphansi uma kuqhathaniswa nezindlela zokugaya ezimanzi.
• Ukugqokwa Okuncishisiwe: Idizayini yama-HPGRs isiza ukunciphisa ukuguga kumaroli nezinye izingxenye, okuholela ekuphileni okude kokusebenza kanye nezindleko zokunakekela eziphansi.

Kodwa-ke, kubalulekile ukuqaphela ukuthi ama-HPGR aphinde abe nemikhawulo nezinselele, njengokuzwela okwenyukayo ezinhlobonhlobo zezakhiwo ze-ore kanye nezinkinga ezingaba khona ezinemiphumela enqenqemeni kanye nokuba buthaka kwezinhlayiyana.

Ukusebenza kwama-HPGR kudinga ukuklanywa kwenqubo ngokucophelela kanye nokwenza kahle ukuze kuqinisekiswe ukusebenza kahle nangempumelelo. Izinto ezifana nesivinini sokuqengqeleka, usayizi wempahla yokuphakelayo nokusatshalaliswa, ukuvikela ukugqokwa kwendawo, kanye nokucushwa kwesekhethi kukonke kudlala indima ekunqumeni ukusebenza kwesekethe yokugaya esekelwe ku-HPGR.
