Migodhi mishanu muEurope inotora chikamu mu €7m digitization chirongwa
Masangano gumi nematanhatu ari muEuropean Union abatana muDig_IT, mubatanidzwa uri kuzopa € 7-miriyoni ichaitirwa chirongwa chinonzi A Human-centred Internet of Things Platform for the Sustainable Digital Mine of the Future.
Chinangwa chepurojekiti ndechekuisa digitize nemashandiro munzvimbo dzakasiyana dzemigodhi mukondinendi, dzinoti La Parrilla tungsten open-gomba mugodhi muSpain; mugodhi wemarble wepasi pevhu weMarini Marmi muItaly; mugodhi weTitania ilmenite wakavhurika muNorway; mugodhi wesirivha weSotkamo uri pasi pevhu muFinland; uye mugodhi wesimbi wakavhurika weHannukainen, mhangura nendarama muFinland, uyo uri kuvhurwazve.
Pasi pehutungamiri hweAragón Technological Institute, zvinangwa zvepurojekiti zvinofanirwa kuzadzikiswa nekugadzira internet-ye-zvinhu indasitiri chikuva kana IIoT inobatanidza uye inoongorora data kubva kuvashandi, michina, nharaunda yakapoteredza uye misika.
"Pamwero wevanhu, chikuva chinounganidza ruzivo rwevashandi, nzvimbo yavo uye mamiriro ezvakatipoteredza munzvimbo dzavanoshanda. Padanho remuchina, ichatarisa kushanda, chinzvimbo, uye mamiriro emidziyo, mota uye maturusi anoshandiswa pakuchera migodhi.
Kuongorora nharaunda yakapoteredza, ichanyoresa mamiriro ezvakatipoteredza, semuenzaniso, kunaka kwemhepo nemvura, tembiricha, uyewo mamiriro enzvimbo, kureva kuti, seismic mamiriro uye kugadzikana kwemateru,” murongi wepurogiramu María García Camprubí. akadaro munhau yenhau.
Sekureva kwaGarcía Camprubí, chishandiso ichi chichabatanidzawo data remusika senge ruzivo rwekupa-kudiwa uye mitengo yezvinhu.
Murongi weprojekiti akati iyi haisi 'hombe-data' chirongwa. Asi, zvinotariswa zvichange zviri pamhando yedata uye dudziro yavo chaiyo munguva-chaiyo yekugonesa maitiro emigodhi nemashandiro. Kuti uwane chinangwa ichi, iyo consortium ichavimba nedhijitari tekinoroji, nzira dzekuongorora data, maitiro ekuenzanisa, kugadzirwa kwemapatya edhijitari, kufonerana uye kusimudzira sensor.
García Camprubí akati kukoshesa kwakakosha kuchaiswa pakusikwa kwemapatya edhijitari kuti agadzirise kugadzirisa kwemidziyo, kugadzikana kwevhu, uye kunaka kwemhepo nemvura.
Kunyangwe nzvimbo yega yega ichizogadziriswa nesangano rakasiyana, mamodheru anozogadziriswa achagadziriswa naCaelia Twinkle, dijitari-mapatya ekuvaka kernel yeinjiniya yenguva chaiyo yekombuta, iyo inobvumira kubatanidza mapatya edhijitari mune imwe neimwe yemugodhi IIoT papuratifomu.
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.
