Indlela Izinsiza Ze-HPGR Ezithuthukisa Ngayo Ukusebenza Kokugaya

Ama-HPGR athuthukisa ukusebenza kahle kokugaya ngokuyinhloko ngokusebenzisa indlela yokuphuka ehluke kakhulu neyonga amandla ebizwa ngokuthi i-inter-particle comminution. Le nqubo ayidli nje kuphela amandla amancane kakhulu (ama-20-50% ngaphansi) kunezigayo zokugaya zendabuko kodwa iphinda ifake imifantu emincane ezinhlayiyeni, okwenza izigaba zokugaya zibe lula futhi kuthuthukiswe ukukhululeka kwamaminerali, okuthuthukisa ukutshala kwezitshalo kanye nokululama kwe-metallurgical.

Indlela Izinsiza Ze-HPGR Ezithuthukisa Ngayo Ukusebenza Kokugaya

1. I-Core Mechanism: Isebenza kanjani i-HPGR

Ukuze uqonde ukusebenza kahle kwayo, okokuqala udinga ukuqonda ukuthi isebenza kanjani, ehluke kakhulu ku-SAG evamile noma i-Ball Mill.

Okuphakelayo Isingeniso: Impahla (insimbi) iklinywa isuka ku-hopper iye esikhaleni esiphakathi kwamaroli amabili amakhulu, aphendukayo.

Indawo Yokucindezela Okuphezulu: Iroli eyodwa ilungisiwe, kuyilapho enye ikusistimu ye-hydraulic eyivumela ukuthi inyakaze, ifaka ukucindezela okukhulu (okuvame ukuba >100 MPa) kokubalulekile.

I-Particle Bed Compression: Njengoba impahla idonselwa esikhaleni, yakha "umbhede" ocindezelweyo. Okubalulekile ukuthi ingcindezi ayisetshenziswa ezinhlayiyeni ngazinye ngokumelene nendawo yensimbi. Kunalokho, amandla adluliselwa ngombhede wezinhlayiya.

I-Inter-Particle Comminution: Lena imfihlo yempumelelo ye-HPGR. Ukucindezela okukhulu kubangela ukuthi izinhlayiya zichobozelane. Ukugaya i-rock-on-rock konga amandla kakhulu kunomthelela we-rock-on-steel kanye nokuqina okwenzeka emshinini wokugaya ibhola.

Ukukhipha: Impahla iphuma kumaroli "njengekhekhe" elihlangene, eliphukayo noma "i-flake," elibe selihlukaniswa ngaphambi kokudlulela esigabeni esilandelayo.

2. Izindlela Ezibalulekile I-HPGR Ithuthukisa Ukusebenza Kokugaya

Izinzuzo ezisebenza kahle kulo mshini zingahlukaniswa zibe yizindawo ezimbalwa ezibalulekile.

a) I-Superior Energy Efficiency (Inzuzo Eyinhloko)

Lena inzuzo ebaluleke kakhulu. Ukugaya kuyinqubo edinga amandla kakhulu emisebenzini eminingi yezimayini.

Ukusetshenziswa Kwe-Direct Force: Emshinini wokugaya ibhola, inani elikhulu lamandla liyamoshwa ngokuphakamisa izinkulungwane zamathani amabhola ensimbi kanye nodaka, ngamandla amaningi alahlekile njengokushisa nomsindo phezu komthelela. Ku-HPGR, cishe wonke amandla avela kumamotho kanye nesistimu ye-hydraulic asetshenziswa ngqo kumbhede wezinhlayiyana ukuze aphuke.

Imodi Yokuqhekeka Ephumelelayo: Ukuhlanganiswa kwezinhlayiyana kusebenza kahle kakhulu ngokwemvelo. Isebenzisa amaphuzu abuthaka kakhulu esakhiweni sedwala, idinga amandla amancane ukuze izuze ukuncipha kosayizi ofanayo.

Umphumela: Amasekhethi e-HPGR angasebenzisa amandla angaphansi ngo-20-50% (akalwa nge-kWh/ton) kunesekhethi evamile ye-SAG/Ball Mill ukuze azuze usayizi wokugcina womkhiqizo ofanayo.

b) Ukukhiqizwa kwama-Micro-Cracks (Ukugaya Okuthuthukisiwe)

Ukucindezela okukhulu akugcini nje ngokuqhekeza izinhlayiya; kudala ukuminyana okuphezulu kwama-micro-cracks kanye nokuphuka ngaphakathi kwezinhlayiya ezinganqamuki ngokugcwele.

Okuphakelayo Okubuthakathaka: Le nto "eyenziwe buthaka ngaphambili" inikezwa esigabeni esilandelayo sokugaya (ngokuvamile isigayo sebhola).

Ukugaya Okulula Kwezansi Komfula: Isigayo sebhola manje sinomsebenzi olula kakhulu. Kudinga amandla omthelela amancane kanye nesikhathi esincane ukuhlephula lezi zinhlayiya ezaphukile kuze kufike kusayizi wokugcina oqondiwe.

Umphumela: Lo mphumela unomthelela omkhulu ekwandeni kokuphuma kokusebenza kwayo yonke isekethe yokugaya. Umshini wokugaya ibhola owake wacubungula amathani ayi-1000 ngehora manje usungase ucubungule amathani ayi-1200-1400 ngehora omkhiqizo we-HPGR ukuze uzuze ukugaya okufanayo.

c) Ukukhululwa Okukhethekile Kwezimbiwa

Ingcindezi ku-HPGR ivamise ukuphula izinhlayiya eduze kwemingcele yazo yemvelo yokusanhlamvu—isixhumi esibonakalayo phakathi kwezimbiwa ezibalulekile (isb., ithusi, igolide) kanye netshe lemfucuza (ganggue).

Ukugaya Kwendabuko: Ukugaya okunomthelela emshinini wokugaya akwenzeki. Ingaphahlaza izinhlayiya ezisanhlamvu eziyigugu zamaminerali, ngezinye izikhathi ivale izinhlayiya zamaminerali phakathi kwezinhlayiya ezinkulu ze-ganggue.

I-HPGR Ukugaya: Ngokuphula imingcele, i-HPGR "ikhulula" amaminerali abalulekile ngokuhlanzeka kakhulu.

Umphumela: Lokhu kuholela ekusebenzeni okuthuthukisiwe kwe-metallurgical. Ukukhululwa okungcono kusho amazinga aphezulu okuthola kabusha ezinqubweni ezansi nomfula njengokuntanta noma ukuvuza, njengoba iminerali eqondiwe itholakala kakhulu kuma-reagents amakhemikhali.

d) Ukunciphisa Ukusetshenziswa Kwemithombo Yezindaba Yokugaya kanye Nezinsimbi

Ayikho Imidiya Yokugaya: Ama-HPGR awasebenzisi amabhola ensimbi, okuyizindleko ezinkulu zokusebenza (ezisebenzisekayo) ezigayweni zamabhola.

I-Lower Liner Wear: Ngenkathi i-HPGR iginqika ngokwawo iguga futhi idinga ukushintshwa okubizayo noma ukuvela kabusha, izindleko zokuguga zizonke ngethani ngokuvamile ziba ngaphansi kunezindleko ezihlanganisiwe zamalayini kanye nokugaya imidiya emshinini wokugaya ovamile. Umbhede wezinhlayiyana ngokwawo wenza ungqimba oluvikelayo "oluzenzakalelayo" endaweni ye-roll, enciphisa ukuguga okuqondile.

e) Ukuguquguquka Ekusebenzeni (Kumanzi noma Komile)

Ama-HPGR angasebenza ome ngokuphelele. Lokhu kuyinzuzo enkulu ezindaweni ezomile, ezintula amanzi lapho ukuthola amanzi omjikelezo wokugaya okumanzi kubiza kakhulu noma kulimaza imvelo.

Lokhu futhi kuqeda isidingo semishini yokukhipha amanzi ebizayo kweminye imiklamo yesekethe.

Ithebula lokuqhathanisa: HPGR vs. Traditional Mill (Ibhola/SAG)

Imishini ye-HPGR ithuthukisa ukusebenza kahle kokugaya hhayi nje ngokuba "i-crusher" engcono, kodwa ngokushintsha ngokuyisisekelo izakhiwo zensimbi. Ngokusebenzisa indlela esebenza kahle kakhulu yokuhlanganisa izinhlayiya, kunciphisa izindleko zamandla, kwenyusa umthamo wesikhungo sonke ngokwenza umsebenzi ongaphansi komfula ube lula, futhi kwenze ngcono ukutholwa kokugcina kwamaminerali abalulekile, kuhlinzeke ngentuthuko enezici eziningi kuyo yonke isekethe yokuqalisa kabusha.
