Magnetite ine simba guru remagineti, uye inonyanya kusanganisira single magnetite, vanadium-titanium magnetite, mixed ore ine magnetite ne iron oxide, uye ore ine magnetite polymetallic symbiosis. Magnetite yakakamurwa kuita coarse-grained, medium-fine-grained, uye micro-fine-grained zvichienderana nehukuru hwayo hwe particle. Pakati padzo, iron ore ine coarse ne medium-fine grains inogona kupwanywa nekukuyiwa kuti iwane qualific iron ore concentrate ne weak magnetic separation process. Micro-particle embedded magnetite inoda kukuyiwa zvakanaka kusvika monomer yanyatsopatsanurwa, uye yobva yapfuudzwa nenzira dzakawanda dzekusarudza kuti iwane beneficiation indicators dziri nani.
JCTN magnetic separator yekunatsiridza uye kuderedza slag yakagadzirwa neHuate Magnet isimba remagineti rakanyorova rakagadzirirwa kushambidza nekuchenesa magnetite. Rakakodzera kupatsanura nekubvisa sliming yezvigadzirwa zve overflow zvekukuya nekuisa muchikamu chekutanga; usati wagadzira grinding yechipiri Uye huwandu hwemineral usati waisa; kubvisa sliming magnetite isati yapinda mu fine sefa nekubvisa sliming isati yapinda mu reverse flotation; sarudzo yekupedzisira yemagnetite, iyo yakaoma kuvandudza giredhi re fine particles ne fine particles mukuparadzanisa kwe magnetic kwakajairika Iron ore ine mhedzisiro yakajeka yekuronga.
Kushandiswa kweMagnetic Separator yekuchenesa uye kuderedza tsvina muMagnetite yakanaka
Magnetite yakanaka munzvimbo yeBenxi ndeye sedimentary metamorphic lean magnetite. Chicherwa chikuru chesimbi cheore imagnetite. Zvichienderana nehunyanzvi hwemaore emagnetite, kambani yedu yakaita muchina wekuyedza wekuparadzanisa magineti wekugadzirisa nekudzora slag. Kuedza nemabheti emichina yemaindasitiri zvakashandiswa mukugadzira maindasitiri. Kushandiswa chaiko kwemuchina wekuderedza slag wakagadziridzwa kwakarumbidzwa uye kwakazivikanwa nevatengi. Nekuda kweizvi, muchina wekuderedza slag wakagadziridzwa wakakwanisa kushandiswa munzvimbo yeBenxi. Wakakurudzirwa zvikuru uye wakashandiswa. Ruzivo rwemaindasitiri rwuri panzvimbo iyi runoratidza:
1. Kushandisa magnetic separator yekunatsiridza uye kuderedza slag sedanho rekutanga rekupatsanura magnetic, ukuwo uchiita shuwa kuti tailings grade haisi pamusoro pe1%, saizi ye original ore inowedzerwa kubva pa -200 mesh 80%, uye grade iri pa 28% kusvika pa concentrate grade ye 52%. Ne 14%, magnetic separator inonatsiridza slag haingogadzirise grade ye concentrate chete, asiwo inorasa tailings dzakawanda, izvo zvinoderedza huwandu hwekukuya kwechipiri uye zvinochengetedza kushandiswa kwesimba;
2. Muchina wekugadzirisa magineti wekugadzirisa nekudzikamisa masimbi unoshandiswa pakugadzirisa masimbi, uye saizi yechinhu cheore i -600 mesh 85%. Kana chiyero chekugadzirisa masimbi chakaenzana, zvinogona kuonekwa kuti muchina wekugadzirisa magineti wekugadzirisa masimbi wechikamu chimwe chete unogona kutsiva magineti akajairwa akabatana nezvikamu zvakawanda. Muchina uyu unosarudzwa kuti upfupise kufamba kwemaitiro uye kuzadzisa chinangwa chekuderedza mari uye kuwedzera kushanda zvakanaka.
Hunhu hukuru hwehunyanzvi hwemagineti hwekuparadzanisa kwekugadzirisa uye kuderedza slag
■ Shandisa musanganiswa wemudziyo wekudyisa machubhu nemidziyo yekudyisa mvura yakawanda kuti uwane chinangwa chekudyisa zvakaenzana;
■ Gadzirira rudzi rutsva rwechimiro icho mugero wemvura uri pasi nedhiramu zvinotenderera zvichipesana nekutenderera, izvo zvinogona kuwedzera mwero wekudzoreredza zvicherwa;
■ Tangi idzva riri pasi pemvura rine nzira yekusuka mvura ine matanho akawanda uye machira emvura epamusoro, ayo anogona kushambidza zvicherwa zvakakwana pamusoro pedhiramu;
■ Kushandisa 240°-270° large wrap angle multi-pole magnetic system, pamwe chete ne magnetic stirging device iri mu cylinder, kunoita kuti zvicherwa zvidonhe uye zvidonhedzwe ne magnetic, uye kana mvura yasukwa, tsvina iri mu concentrate inobviswa zvizere kuti Concentrate grade iwedzere.
■ Mudziyo wekuburitsa zvinhu unoshandisa chimiro che "double scraper" kuti zvicherwa zviwande panguva yekuburitsa zvinhu.
Data rekushandisa remagineti rinoparadzanisa zvinhu kuti rinyatsogadziriswa uye kuderedza tsvina muindasitiri
1. Chinoparadzanisa magineti chekugadzirisa nekudzikamisa slag chinoshandiswa padanho rimwe chete rekuparadzanisa magineti
Gadzirai simbi yesimbi kusvika pa80% ye -200 mesh, uye shandisai magnetic separator kuti munyatsogadzirisa uye mudzikise slag kuti muite magnetic separation padanho rekutanga.
Chinoparadzanisa magineti chinonatsa uye chinoderedza slag hachingogadzirisi chete giredhi re concentrate, asiwo chinobvisa masero akawanda, izvo zvinoderedza huwandu hwekukuya kwechipiri uye zvinochengetedza kushandiswa kwesimba. Chinoparadzanisa magineti chinonatsa uye chinoderedza slag hachingovimbisi chete kuti maitiro acho afambe zvakanaka, asiwo chinochengetedza mari.
2. Magnetic separator yekunatsiridza uye kuderedza slag inoshandiswa pakusarudza
Nekuda kwekuva nepfungwa itsva uye chimiro chemuchina wekugadzirisa magineti wekugadzirisa nekudzora slag, unogona kuderedza kuputira kwemagineti uye kuvandudza giredhi re concentrate, kunyanya kune magnetite ine grained fine.
Kushandiswa kwemuchina wekugadzirisa magineti pakuchenesa nekuderedza magineti kune mhedzisiro yakanaka pakupatsanurwa kwemagnetite ine grained grained muBenxi, Liaoning. Nzvimbo yekupatsanurwa kwemagineti muchikamu chekutanga yakawedzerwa kubva pa28% yegiredhi rekutanga reore kusvika pa52%, inova kuwedzera kwe14%. Muchina wekuderedza magineti wekuderedza magineti haungogadzirisi chete giredhi re concentrate, asiwo unodzinga masero akawanda, unoderedza huwandu hwekukuya kweore muchikamu chechipiri, uye unochengetedza kushandiswa kwesimba; sekusarudza, unogona kuita basa rakajairika rekupatsanurwa kwemagineti rinotsiva matanho maviri akatevedzana. , Nokudaro kupfupisa kufamba kwemaitiro uye kuzadzisa chinangwa chekuderedza mari nekuwedzera kushanda.
