Kudzoreredza indasitiri yezvicherwa kunogona kusimbisa hupfumi hweAustralia zvakare
Ore yesimbi yeRio Tinto inoshanda munharaunda yePilbara yeAustralia. ( Mufananidzo nerubatsiro rweRio Tinto )
Indasitiri yezviwanikwa yeAustralia yakagadzirirwa kubatsira kudzoreredza kwehupfumi zvakare sezvo mitengo yakakwira uye zvirongwa zvekuwedzera zvichibatsira nyika kubuda kubva mukuvharika kwayo.
Migodhi inosvika zvikamu zvitanhatu kubva muzana zvehupfumi hwenyika yose asi inoita basa repamusoro mumari yenyika, ichiendesa migove kuhomwe dzepenjeni uye muhomwe dzehurumende. Iron ore, iyo inonyanya kutengesa kunze kwenyika, yatyora madhora zana patani pakati pekunetsekana kwekupihwa kwemahombekombe, ichipa bhajeti renguva.
"Mushure mekuderera kwemakore akati wandei, migodhi capex yagadzirira kusimuka pamusoro pe2H 2020 uye mberi. Zvikonzero zvekutsvaga mukudyara, zvakadai semitengo yakakwira uye mazinga akakwira ekushandiswa kwekuongorora, anoramba aripo, uye anogona kuona kukwidziridzwa kwekudyara kupfuura kutsiva nhanho mumakore anotevera. "
James McIntyre, nyanzvi yezvehupfumi
Huwandu huchangoburwa hwebhajeti rehurumende kubva muna Zvita hwakanga hwakavakirwa pasimbi inodonha kusvika pamadhora makumi mashanu nemashanu patani, tisingabatanidzi kutakura zvinhu, panosvika kota yaChikumi ye2020. Hurumende inowana mari inosvika mabhiriyoni matatu nemazana manomwe emadhora pamadhora gumi ega ega inodarika fungidziro iyi mugore kusvika Chikumi 2021. , iyo inobatsira iyo bhajeti chinzvimbo zvichitevera hombe jekiseni remari.
Muna 2009, Australia yakadonhedza kuderera kwehupfumi uye yakatanga kupora sezvo China yakadonhedza mari inodarika mazana mashanu emabhiriyoni emadhora muhupfumi hwayo zvichikurudzira kuwedzera kwekudyara kwemugodhi Down Under. Pakeji yekusimudzira yeChina idiki zvakanyanya panguva ino - uye Australia yatove kuderera - asi nzira iri pamberi inogona kuratidza yakafanana.
Ukama hwakakanganiswa
Ipo, hukama hweAustralia neChina huri mumvura ine dutu zvichitevera kudana kweMutungamiriri weScott Morrison kuti iongororwe yakazvimirira pamusoro pekwakabva coronavirus, zvinhu zvakakosha zvakawanda zvakavharirwa kubva ku spat nekuda kwekushomeka kwevatengesi vemhando yepamusoro kumwe kunhu.
China yakapfura pfuti yambiro kuAustralia nemitero yebhari uye kumiswa kwekutakura kubva kune dzimwe nzvimbo dzekudyira. Kunetsana kwakawedzera neChishanu apo Bazi reChina reTsika neKushanya rakaburitsa chirevo pawebhusaiti yaro richiti vashanyi vekuChina vanofanira kungwarira kuchengetedzeka kwavo uye kuti vasaende kuAustralia.
Andrew Ticehurst, nyanzvi yemitengo paNomura Holdings Inc., ari kunetsekana kuti kusawirirana kunogona kudzikamisa kukwira.
"Haizosimba sezvakaita 2009 apo paive nepombi yemapurojekiti, asi zvakanaka kana ukaisa pamwe chete mari yezvicherwa, mamiriro ekutengeserana uye kusangana kwedu neChina."
Shane Oliver, mukuru wezvehupfumi kuAMP Capital Investors Ltd.
"Iron ore inzvimbo inopenya yeAustralia," akadaro. "Zvisinei, nekudzikira kuri kuita hukama hwekutengeserana neAustralia neChina, China ingasada kuonekwa 'seinopa mibairo' kuAustralia zvakanyanya, uye kutengwa kwesimbi kwakakwira kunogona kudzikiswa nekudzikiswa kwezvimwe zvinhu, zvinhu nemasevhisi."
Kuenderera mberi nekubatsira vagadziri vesimbi vepamba, mukwikwidzi mukuru weAustralia, Brazil, akamanikidzwa kuvhara nzvimbo dzemigodhi sezvo nyika ichirwira Covid-19.
Rio Tinto Group, mucheri wepasi rose wepamugodhi, muna Mbudzi yakasimudza kushandiswa kwakarongwa pamigodhi mitsva yesimbi muAustralia kusvika pamabhiriyoni mana emadhora, ukuwo BHP Group neFortescue Metals Group Ltd. dziri kudyara mari inodarika mabhiriyoni matatu emadhora imwe neimwe mubudiriro yadzo. Migodhi iyi ine chinangwa chikuru chekutsiva nzvimbo dzavacharega kuti dzienderere mberi nekutengesa kunze, asi ichizopa sarudzo dzekuwedzera kutakura.
Vagadziri vemarasha negoridhe vari kushandisawo mari muzvirongwa zvitsva muAustralia uye mabhajeti ekuongorora ari kuwedzera. Vacheri vegoridhe vekuAustralia - vari munzira yekuve mugadziri wepamusoro - vari kutangisa denda-rakavhiringika ongororo pakati pemitengo.
Ball Mill Liner Material Sarudzo
Yakasiyana yakapwanyika zvinhu, akasiyana ekushanda mamiriro anoda akasiyana zvinhu liner kuti aenderane. Zvakare, iyo yakakasharara yekukuya compartment uye yakanaka yekukuya compartment inoda akasiyana matinji.
H&G Michina inopa zvinotevera zvinhu kukanda yako bhora chigayo liner:
Manganese Steel
Iyo manganese yemukati meyakakwira manganese simbi bhora chigayo lining plate inowanzo 11-14%, uye iyo kabhoni yemukati inowanzo 0.90-1.50%, mazhinji ayo ari pamusoro pe1. Pamitoro yakaderera, kuoma kunogona kusvika HB300-400. Pakukwirisa mitoro, kuoma kunogona kusvika HB500-800. Zvichienderana nekutakura mutoro, kudzika kweiyo yakaomeswa layer inogona kusvika 10-20mm. Iyo yakaomeswa layer ine kuomarara kwakanyanya inogona kuramba kukanganisa uye kuderedza abrasive kupfeka. Yakakwira manganese simbi ine yakanakisa anti-kupfeka mashandiro pasi pemamiriro eiyo yakasimba kukanganisa abrasive kupfeka, saka inowanzoshandiswa munzvimbo dzisingapfeki dzemigodhi, zvekuvaka, simba rekupisa, uye zvimwe zvemichina. Pasi pemamiriro ekuderera kwemamiriro ezvinhu, yakakwira manganese simbi haigone kuita hunhu hwechigadzirwa nekuti basa rekuomesa mhedzisiro haisi pachena.
