Iron ore masimba anopfuura $100 sezvo dambudziko rekupa rinosangana nezvinodiwa zvakasimba
Iron-ore yakapfuura $100/t sezvo dambudziko rekupa muBrazil richienderana nekugara, kudiwa kwakasimba mukugadzira simbi yepamusoro China.
Mitengo yeBenchmark yakakwira kusvika pamadhora zana neshanu neChishanu sezvo Brazil, mutengesi wechipiri pakukura pasirese, yakaona kuwedzera kwehutachiona hwekoronavirus, zvichikonzera kushushikana kuti denda rinogona kumisa kuwanikwa kwenzvimbo. Muna Kubvumbi, mugodhi Vale akacheka gwara rake repagore rekutumira pamamiriro ekunze akaipa uye kukanganisa kwehutachiona pakushanda. Zvichakadaro, chiteshi chengarava chesimbi-ore muChina chakaramba chichidzikira.
Chimiro cheindasitiri chakabudirira muna 2020 kunyangwe denda rekoronavirus rakapfunya chisero cheindasitiri muhupfumi hwakawanda, kunyangwe Bloomberg Intelligence yanga iri pakati pevacherechedzi yambiro kuti musika unogona kukwira kune yakawandisa muhafu yechipiri. Pamusoro peVale, mitengo yakakwira ichasimbisa kudzoka kuBHP Group, Rio Tinto Group neFortescue Metals Group.
Kutangwazve kwekushanda kwemaindasitiri muChina kwakakurudzira kudzoreredzwa mumabasa ezasi uye zvigayo zvesimbi zvinoramba zvichiwedzera kubuda, vaongorori veChina International Capital Corp. vanosanganisira Ma Kai vakanyora mune imwe tsamba.
"Iron ore ichachengetedza chiyero chakasimba gore rino," nekupa zvishoma nezvishoma kupora kubva muchikamu chechitatu, vakadaro.
Benchmark nzvimbo mitengo iri pamusoro kubva Nyamavhuvhu. Ramangwana muSingapore rakanga riri pamadhora makumi mapfumbamwe nemanomwe, vachitungamira kuwana kwavo kukuru kwepamwedzi. PaDalian Commodity Exchange, ramangwana rakawedzera 23% muna Chivabvu.
Chikwereti Suisse Group nguva pfupi yadarika yakafungidzira kuti musika wave pa "peak tightness," mamiriro angangoenderera kusvika Chikunguru. Bloomberg Intelligence inotarisira 34-miriyoni-matani akawandisa muhafu yechipiri pane yakakwira kupihwa uye kuderera kudiwa, kubva pakushomeka kwemamiriyoni makumi maviri neshanu muhafu yekutanga. Izvi zviri kuisa chitarisiko chekuti mutengo unowanikwa wakagadzikana here.
"Pachine kusahadzika" nezvekusimba kwerally mumwedzi unotevera kusvika kumwedzi mitatu, akadaro Hui Heng Tan, muongorori weMarex Spectron Group. Pikipiki iri kuwanikwa muAustralia neBrazil inotarisirwa kukwira, kunyangwe kukanganisa munyika yeSouth America kuchave chinhu chekuona muhafu yechipiri, akadaro. Kuwedzera uku kwemavhoriyamu kunogona kuenderana kana China yabuda nguva yayo yepamusoro yekuvaka nematura esimbi akakwira, akadaro.
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.
