Codelco kumisa mapurojekiti ekuvaka ekuchamhembe

Chile inodzorwa nehurumende yemugodhi weCodelco copper yakati nemusi weMugovera ichamisa zvirongwa zvekuvaka kuchamhembe kwenyika uye kuyedza kuchengetedza kugadzirwa pamugodhi wayo weChuquicamata panguva yekushanda nevashandi veko.

Kambani iyi yakaburitsa chirevo ichiti yave kutora matanho ekudzivirira kupararira kwegoronavirus mushure mekunge hurumende yataura nezvekuwedzera kwenzufu dzine chekuita nehutachiona kutanga neMugovera.

Mukati mekuedza kurongazve chirevo chayo chinoshoropodzwa zvakanyanya kufa kwevanhu vane hutachiona, hurumende yakawedzera huwandu hwayo hunofungidzirwa hwemhosva dzinouraya kusvika vanopfuura zviuru zvinomwe kubva kune zviuru zvina nemazana maviri nemakumi matanhatu neshanu.

Chiziviso cheCodelco chakauya maawa mashoma mushure mekufa kwechipiri-kwakanangana neconavirus kwemushandi weCodelco kwakasimbiswa.

Kambani iyi yakati mugodhi wayo weChuquicamata, uko kufa kwekutanga kwekoronavirus kutanga kwemwedzi uno, uchashanda chete nevashandi vanobva kudhorobha riri pedyo reCalama kudzikamisa kupararira kwedenda.

"Kubva zvino vashandi vachabva kuCalama chete," chirevo chakadaro, chichiwedzera kuti "zvichaitwa kuchengetedza huwandu hwekugadzira pamugodhi."

Basa rekuvaka rine chinangwa chekupedzisa chirongwa cheChuquicamata Subterranea kuchamhembe kweChile richamiswa sezvo kambani inosimbisa matanho ayo ekurwisa hutachiona, chirevo chakadaro.

Ball Mill Liner Installation Zvinodiwa

1. Mushure mekunge chigayo chaiswa, iyo yekupedzisira lining plate uye cylinder end cover inofanira kuzadzwa necompressive simba giredhi 43.5MPa sement mortar.
2. Mabhaudhi anogadzirisa magumo ekupedzisira haabvumiri dhaka resimende kuti rikwane, asi richakwanisa kutenderera kana kupinda nekubuda.
3. Iyo bhora mill lining kazhinji inotungamira, iwe unofanirwa kuiteerera panguva yekuisa, usatendeuke.
4. Iyo arc kureba kwese circumferential slits haifanire kudarika 310mm, uye iyo yakawandisa ichabatanidzwa nemarata esimbi kuiparadzanisa.
5. Mukana uri pakati pemabhini ari padyo haupfuuri 3 ~ 9mm.
6. Iyo interlayer inofanira kuiswa maererano nezvinodiwa zvekugadzira pakati pe liner uye mukati mepamusoro pe cylinder. Kana pasina chinodiwa, dhaka resimende rine simba rekumanikidza re42.5MPa rinogona kuzadzwa pakati pezviviri. Mushure mokunge dhaka resimende rakagadzika, simbisai mabhoti emagetsi zvakare.
7. Paunenge uchiisa liner nemapedhi erubha, vhura pepa rerabha rakaputirwa mavhiki matatu kusvika mana usati waiswa kuti ritenderere kutambanudza zvakasununguka; paunenge uchishandisa jira rerubha, rutivi rurefu rwepepa rerubha runofanira kutevera axial kutungamira kwecylinder, Rutivi rupfupi runotevera denderedzwa rehumburumbira.
8. Nyatsotarisa maburi ebhoti uye geometry yemabhoti emagetsi, uye nyatsochenesa maburi emagetsi, mabheji, uye protrusions pamaburi ebhoti uye mabhoti kuitira kuti mabhoti apinde akasununguka munzvimbo inodiwa.
9. Iyo yakazara seti yemabhoti e-liner inofanira kunge ine glaring bolts, guruva washers, flat washers, spring washers, uye nzungu; kuitira kudzivirira kubuda kwedota, haufanirwe kukanganwa kushandisa guruva pads panguva yekushandisa.
10. Paunenge uchiomesa mabhaudhi, chipanera che torque chinofanira kushandiswa pakuvhiya. Lining mabhaudhi eakasiyana maratidziro anofanirwa kusimbiswa zvinoenderana neino enderana inosimbisa torque zvinodiwa.

Ball Mill Liner Kuiswa

1. Usati waisa bhora rechigayo liners, iwe unofanirwa kuziva kuti mangani mapcs ekare mall liner anoda kuchinjanisa.
2. Bvunza nyanzvi kuronga uye kuronga yose yekutsiva maitiro. Zvese zvekutsinhana zvinoda zvichibva pamifananidzo yebasa.
3. Izvo zvinodikanwa kutenderedza pulp yakasara muguyo rebhora zvakanyanya sezvinobvira, bvisa pedhi yerabha yemarara, kuchenesa nzvimbo inobuda yemadziro ebhora, uye kubvisa guruva uye descale cylinder. Paunenge uchichenesa basa, zvakakosha kugadzirisa bhodhoro rebhoti yebhora. Wekishopu inoda kuve nemamiriro ekufema zvakanaka uye tembiricha yakakodzera. Ipapo mugadziri anogona kupinda mubhora reguyo kuti atange oparesheni.
4. Paunenge uchibvisa chigayo chekare chebhora, tanga wabvisa zvigayo zvakashandiswa, wozobvisa bhora rekare mutsara mushure memutsara mumwe, uye wozosimudza bhora rakashandiswa. Paunenge uchibvisa liner, munhu wacho anofanira kutarisisa kuchengetedzwa uye teerera kune yakamira kuti arege kukuvadzwa nebhora regiyo.
5. Iyo liner nyowani yechigayo chebhora inofanirwa kuiswa kuti ive nechokwadi chekuti gap panguva iyo iri mukati mechikamu chinodiwa. Gadzirisa spiral yeball mill liner. Nyatsosimbisa kurongedza uye gasket kudzivirira kubuda kwemamineral poda. Kana pasina gasket, inofanira kuputirwa munzvimbo inowirirana. Matenderedzwa maviri etambo yedonje kana hemp pamwe nemafuta ekutungamirira. Panguva imwecheteyo, zvakakosha kuisa dhaka resimende pamadziro emukati we cylinder uye kuiputira zvakasimba isati yasimbiswa. Izvo zvinofanirwa kucherechedzwa kuti iyo yakaonda yekupedzisira yenhanho liner inofanirwa kuenderana nekutungamira kwemuseve munzira yekutenderera kweguyo.
6. Mushure mekutsiviwa, vashandi vehuyo bhora vanofanira kusimbisa kuti hapana munhu, hapana maturusi ekushanda, uye zvimwe zvinhu zvisingakoshi muhumburumbira, uye zvakakosha kunyatsoongorora mukati nekunze kwe cylinder usati wavhara chivharo chisina chinhu.
