Simbi inoraswa, senzira yekupedzisira yekurasa tsvina inogadzirwa nekunyungudutsa simbi, ine zvinhu zvesimbi zvakawanda. Nekuda kwekuwanda kwayo uye huwandu hwayo hwakawanda, haigone kufarirwa uye kushandiswa muindasitiri yekuvaka. Zviwanikwa zvesimbi zvinokosha hazvina kuwanikwa zvakanaka, zvichikonzera huwandu hwakati hwemarara. Simbi inofanira kudzokororwa uye kushandiswazve kuburikidza nenzira yakati yekuparadzanisa magineti, uye inosangana nezvinodiwa zvemhando yesimbi yeupfu inodiwa nezvinhu zvine simbi zvekunyungudutsa blast furnace, kuitira kuti simbi inoraswa igone kudzokororwa. Inogona kushandiswa zviri nani mukuvaka.
Parizvino, imwe nzira yekuparadzanisa magineti inzira inogoneka, uye zvakakosha kusarudza michina yakakodzera kuti iparadzirwe simbi uye idzorerwe zvakanaka. Simbi inopwanywa kuti iparadzirwe, uye kuburikidza nemhepo, simbi yeupfu inopatsanurwa, simbi inodyirwa, uye simbi inosanganiswa nesimbi inotorwa, uye huwandu hwesimbi hunoongororwa uye hunotsanangurwa kuti huwane nzira dzakanakisa dzekugadzirisa nekushandisa. Ipa rutsigiro rwehunyanzvi rwakakodzera pakugadzira chaiko.
Zvivako zvesimbi zveslag
Simbi inoraswa marara inogadzirwa nekushandisa lime ine magnesium yakawanda, lime inoshanda nezvimwe zvinhu zvinobatsira zvekubvisa kusvibiswa uye kufefetera okisijeni mukugadzira simbi, saka ine iron oxide yakawanda, kazhinji 20%-40%, uye huwandu hweFeO hunopfuura Fe2O3, yekutanga inowanzova 15%-25%, nepo yekupedzisira iri 5%-15%, zvese zvinoratidza simba remagineti.
Midziyo yekuedza
Midziyo yekuedza inoshandisa FX0665 powder ore air dry magnetic separator yeHuate Company, iyo inonyanya kushandiswa pakusarudza magnetite isati yagayiwa kana kugadzira qualified concentrate kubva kupowdered magnetite.

Pfungwa yekushanda kwemuchina wekugadzira magineti wepowder ore air dry magnetic separator inoratidzwa mumufananidzo. Zvicherwa zvinopihwa pamusoro pedhiramu remagineti kuburikidza nechiteshi chekudyisa ore 3, uye zvicherwa zvemagineti zvinonamirwa pamusoro pedhiramu remagineti 4 pasi pesimba remagineti, uye zvinotenderera nedhiramu remagineti 4. Munguva iyi, zvicherwa zviri pamusoro pedhiramu remagineti 4 zvinosangana nekushanda kwakabatana kwemagnetic pulsation yematanda makuru ewrap-angle nematanda akawanda, mudziyo wekusanganisa magineti, mudziyo wekupinda mweya 6 uye chiteshi chekubvisa guruva 5, kuitira kuti tsvina iri muzvicherwa nezvisikwa zvisina kusimba zvakabatana zvibviswe zvinobudirira. Nokudaro, giredhi remuchina wekuwedzera rinovandudzwa. Mushure mekunge zvicherwa zvasarudzwa zvatenderedzwa kunzvimbo isina magineti nedhiramu remagineti 4, zvinowedzerwa muchiteshi chekuwedzera 9 pasi pekushanda kwegravity, centrifugal force uye mudziyo wekuburitsa zvinhu kuti zvive concentrate. Zvicherwa zvisina magineti kana miviri yakabatana yakaonda hazvibvi mumuromo we tailings pasi pesimba regiravhiti uye simba re centrifugal, uye zvinova tailings kana simbi yepakati.
Kugadzira zvinhu zvitsva uye tekinoroji yakakosha yemuchina wekugadzira magineti wepoda ore mhepo yakaoma
1. Chinodzungudza chinoshandiswa pakupa chikafu, uye maparamita echinodzungudza anogona kugadziriswa kuti chiwane chikafu chakafanana;
2. Sisitimu yemagineti inoshandisa makona akawanda, kona yakakura yekuputira (kusvika kumadhigirii 200-260), dhizaini yakasimba yemunda (3000-6000Gs), uye chimiro chesisitimu yemagineti chinogona kuchinjwa zvichienderana nehunhu hwezvicherwa kuti zviwane zviratidzo zvine musoro zvekuwedzera simba;
3. Kumhanya kwemuchina wesimbi kunogadziriswa mukati me1-20m/s, uye kumhanya kwakakodzera kunogona kusarudzwa zvichienderana nerudzi rwesimbi; silinda yakagadzirwa nezvinhu zvisiri zvesimbi uye ine mudziyo wekugadzira magnetic kuti uvandudze giredhi re concentrate;
4. Ine chimiro chebanga remhepo, mudziyo wekugadzirisa mhepo uye mudziyo wekubvisa guruva (zviyero zvakakodzera zvinogona kusarudzwa zvichienderana nerudzi uye zvinodiwa ne index yedombo); pamusoro pesirinda pane mudziyo wekuburitsa zvinhu, unogona kuita kuti concentrate ibude yakachena;
FX powder ore air dry magnetic separator inonyanya kuumbwa ne transmission device, magnetic separation drum, blower device, induced draft dust removal device, sedimentation collection device, nezvimwewo. Simba remagnetic field re magnetic separation drum i3500Gs. , magnetic force, rotating centrifugal force, nezvimwewo, inogona kuwana dry pre-selection ye 0-5mm particle size magnetite kana kuvandudza zvakanyanya grade ye fine powder magnetite. Mhedzisiro huru ndeiyi inotevera:
A. Chikamu chakasarudzwa che 0-5mm magnetite chinogona kuwedzerwa kubva pa10% kusvika pa40%. Chinogona kushandiswa sechinoraswa chisati chagayiwa, izvo zvinogona kuvandudza zvakanyanya chikamu chekutanga uye kuvandudza mashandiro echigayo.
B. Chiyero chakasarudzwa che -74um ne -45um magnetite yakanaka chinogona kuwedzerwa kubva pa10% kusvika pa60%, uye hunyanzvi hwakakosha hunogona kuwanikwa zvakananga nekusarudza kwakaoma.
