Guinea inobvumidza SMB-Kuhwina chibvumirano cheSimandou
Hurumende yeGuinea yakabvumidza nemusi weChina chibvumirano chekutanga chekusimudzira chirongwa chayo chikuru cheSimandou iron ore nemubatanidzwa unomiririra zvido zveChinese, French neSingapore, gurukota rezvemigodhi rakaudza Reuters.
Consortium - iyo inosanganisira Société Minière de Boké (SMB) neSingapore's Winning Shipping pamwe nezvido zvehurumende yeGuinea - yakawana tender yemadhora bhiriyoni gumi nemana muna Mbudzi wapera kugadzira zvivharo 1 uye 2 yedhipoziti yakakura kwazvo inozivikanwa yerudzi rwayo, inobata zvinopfuura mabhiriyoni maviri. matani emhando yepamusoro-giredhi ore.
NeChipiri, chibvumirano chayo chebudiriro "chakabvumidzwa. Tichaenderera mberi nekuchisaina mumazuva anotevera,” Gurukota rezvemigodhi, VaAbdoulaye Magassouba, vakadaro vasina kutsanangura.
Nyika yeWest Africa yakatsvaga kuvandudza dhipoziti yeSimandou kwemakumi emakore, asi chirongwa ichi chakanyura mumakakatanwa emutemo akareba uye mitengo yakakwira yakadzora mubereko.
Hurumende yaida kuti vaikumbira kuti vavake njanji ine makiromita 650 (makiromita 400) uye chiteshi chengarava chaizotakura matombo acho kubva kumaodzanyemba kwakadziva kumabvazuva kweGuinea kuenda kumahombekombe kunotengeswa kunze kwenyika.
Vanoisa mari mumubatanidzwa usinganyanyozivikanwa vanosanganisira mugadziri wealuminium wekuChina Shandong Weiqiao, chikamu cheChina Hongqiao neYantai Port Group, pamwe nehurumende yeGuinea.
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.

Chrome Alloy Steel
Chromium alloy cast iron yakakamurwa kuita yakakwira chromium alloy cast iron (chromium content 8-26% carbon content 2.0-3.6%), medium chromium alloy cast iron (chromium content 4-6%, carbon content 2.0-3.2%), yakaderera chromium Mhando nhatu dzealloy cast iron (chromium content 1-3%, carbon content 2.1-3.6%). Chinhu chayo chinoshamisa ndechekuti microhardness yeM7C3 eutectic carbide iHV1300-1800, iyo inogoverwa muchimiro chetambo yakaputsika uye yakaparadzaniswa pane martensite (iyo yakaoma zvikuru musimbi matrix) matrix, kuderedza cleavage effect pamatrix. Naizvozvo, iyo yakakwira-chromium alloy liner ine simba rakawanda, bhora rehuyo kusimba, uye yakakwirira kupfeka kuramba, uye kuita kwayo kunomiririra nhanho yepamusoro yezvinhu zvazvino zvesimbi zvinopfekwa.
