Uruhare rwa HPGR mu Gukwirakwiza Ingufu

Iriburiro:

Comminution, inzira yo kugabanya ubunini bwamabuye y'agaciro, igira uruhare runini mubikorwa byo gutunganya amabuye y'agaciro. Ubusanzwe, iki gikorwa cyakozwe hifashishijwe uburyo busaba ingufu cyane nko gusya umupira hamwe na SAG (Semi-Autogenous Grinding). Ariko, hamwe no kuza kwikoranabuhanga rya Pressure Grinding Rolls (HPGR), habaye impinduka zikomeye zijyanye no gutangiza ingufu nyinshi. Iyi ngingo iragaragaza uruhare rwa HPGR mu gutangiza ingufu n’ingaruka zayo mu bucukuzi bw'amabuye y'agaciro.

1. Gukoresha ingufu mu Kwiyemeza:

Ibikorwa byo gutanga ibicuruzwa bitwara ingufu nyinshi munganda zitunganya amabuye y'agaciro. Bigereranijwe ko 4% by'ingufu zikoreshwa ku isi biterwa no gutangira. Kubwibyo, kuzamura ingufu zingufu muri comminition byabaye ikintu cyambere kubwimpamvu zubukungu nubukungu.

2. Umuvuduko mwinshi wo gusya (HPGR):

Ikoranabuhanga rya HPGR ritanga igisubizo cyiza cyo gutangiza ingufu. Imashini za HPGR zigizwe n'imizingo ibiri irwanya kuzenguruka, ubusanzwe ikozwe mu byuma, hagati aho amabuye y'agaciro agaburirwa. Mugukoresha umuvuduko mwinshi mubikoresho byo kugaburira, HPGRs igera kumeneka ahanini binyuze muguhuza ibice, aho kugira ingaruka cyangwa gukurura.

3. Inyungu za HPGR mu gukoresha ingufu:

Kimwe mu byiza byingenzi byikoranabuhanga rya HPGR nubushobozi bwayo bwo kugabanya ingufu zikoreshwa ugereranije nuburyo busanzwe bwo gusya. Ibi ahanini biterwa no guhitamo kwibohora kwamabuye y'agaciro, kugabanya ingano yo gukabya. Ikigeretse kuri ibyo, uburyo bwo guhuza ibice bigabanya ibintu byiza, biganisha ku buryo bunoze bwo gusya hasi.

4. Kunoza ubuziranenge bwibicuruzwa:

Ikoranabuhanga rya HPGR naryo rigira uruhare mu kuzamura ubuziranenge bwibicuruzwa. Kwibohoza kwamabuye y'agaciro y'agaciro bituma igabanuka ry'umusaruro wa ultra-nziza nziza, zishobora kugorana gukira kandi zishobora gutuma ingufu zikoreshwa mubyiciro bitunganijwe nyuma.

5. Guhindura imikorere:

HPGRs itanga imikorere ihindagurika bitewe nibikorwa byabo bishobora guhinduka. Ikinyuranyo kiri hagati yizingo kirashobora guhindurwa kugirango igenzure ingano y’ibicuruzwa, bikwemerera guhuza inzira n'ibiranga ubutare bwihariye n'ibisabwa byo kwibohora. Byongeye kandi, ubushobozi bwo gutunganya no kongera kumenagura ibice birenze urugero bituma HPGRs ikora ibintu byinshi byingana.

6. Gusaba muburyo butandukanye bwa Ore:

Ikoranabuhanga rya HPGR ryakoreshejwe neza muburyo butandukanye bw'amabuye y'agaciro, harimo amabuye y'agaciro akomeye nk'umuringa, zahabu, n'amabuye y'icyuma. Ibi bikoresho akenshi bisaba gusya neza kugirango ugere kubuntu bwifuzwa bwamabuye y'agaciro. HPGRs yerekanye imbaraga zayo mukugabanya ingano yingirakamaro isabwa mugihe hagabanijwe gukoresha ingufu.

7. Kwishyira hamwe hamwe ninzitizi ziriho:

HPGRs irashobora kwinjizwa mumashanyarazi ariho asanzwe mbere yo gusya cyangwa nkigice cyo gusya imvange. Mugushyira mubikorwa ikoranabuhanga rya HPGR, gukoresha ingufu mubyiciro byakurikiyeho byo gusya, nko gusya umupira, birashobora kugabanuka cyane, biganisha ku kuzigama ingufu muri rusange.

8. Inzitizi n'iterambere ry'ejo hazaza:

Nubwo inyungu nyinshi, hari ibibazo bijyanye no gushyira mubikorwa ikoranabuhanga rya HPGR. Ibi birimo gukenera amabuye akwiye, gucunga imyenda, no kugenzura bihagije umuzenguruko wa HPGR. Imbaraga zubushakashatsi niterambere bigamije gukemura ibyo bibazo no kunoza imikorere yikoranabuhanga rya HPGR.

Umwanzuro:

Umuvuduko mwinshi wo gusya (HPGR) ugira uruhare runini mugushikira ingufu zikoreshwa mu bucukuzi bw'amabuye y'agaciro. Nubushobozi bwabo bwo guhitamo kubohora amabuye y'agaciro no kugabanya gukoresha ingufu, HPGRs itanga inyungu zikomeye muburyo busanzwe bwo gusya. Kwinjiza tekinoroji ya HPGR mumashanyarazi asanzwe itanga amahirwe yo kuzamura ingufu muri rusange mubikorwa byo gutunganya amabuye y'agaciro. Hamwe nogukomeza gutera imbere hamwe no gukoresha uburyo bwihariye bwo gukoresha, tekinoroji ya HPGR iteganijwe kurushaho kwigaragaza mugushakisha inzira zirambye kandi nziza.
