I-ore ye-magnet inezakhiwo ezinamandla ze-magnetic, ikakhulukazi ezifaka i-ore eyodwa ye-magnet, i-vanadium titanium magnet ore, i-magnetite kanye ne-iron oxide mixed ore, i-magnetite multi-metal symbiotic ore, njll. I-magnetite ihlukaniswe ngama-granules ama-coarse, izinhlayiya eziphakathi nendawo, izinhlayiya ezincane ku-magnetite, lapho imayini yensimbi egcinwe ezinhlayiyeni eziphakathi nendawo kanye nezinhlayiya eziphakathi nendawo iphukile. Ngemva kwenqubo yokububula, ingathola ama-concentrates ensimbi afanelekayo ngenqubo yokukhetha i-magnetic ebuthakathaka. Imayini ye-magnet e-Micronardized idinga umshini omncane ukuya ku-monomer eyanele ukuze ifinyelele izinkomba zokusabalalisa ezingcono.
Isixazululo se-JCTN sokudonsa amanzi okwenziwe nge-Walt magnetically siyisihlukanisi esimanzi se-magnetic mine sokuhlanza nokuhlanza imayini ye-magnetine, esifanele ukuhlunga ukususwa komkhiqizo wokuchichima wokugaya; kanye nokuhlushwa kwamaminerali ngaphambi kokuhlunga; i-magnetite ingena ku-pre-sieve sieve pre-sieve pre-sieve pre-seeve pre-seeve pre-seeve pre-seeve pre-seeve pre-seeve pre-seeve pre-demetrics; ukukhetha okuphelele kwe-magnetite kunzima ukuthuthukisa izinhlayiya ezincane zenketho yamagnetic evamile, izinhlayiya ezincane, i-iron ore inomphumela obalulekile wokukhetha.
Isihlukanisi SikaMagnetic Esiyinhloko se-JCTN
Izici zobuchwepheshe eziyinhloko
■ Ukubopha ekuhlanganeni kwezimbiwa kanye nokuchichima kwamanzi kusetshenziselwa ukufeza injongo yokumba okufanayo;
■ Ukusetshenziswa kohlobo olusha lomzimba we-groove ongena-sequenceless kanye nokujikeleza okuphambene ne-roller kungathuthukisa ukubuyiswa kwamaminerali;
■ Ukuhlanza okunezigaba eziningi kanye nesakhiwo samakhethini amanzi angaphezulu kuhlinzekwe emseleni omusha ongenazinhlu, ongahlanza ngokuphelele amaminerali ebusweni besigubhu;
■ Thatha isakhiwo esikhulu sama-magnetic pole angu-240 ° -270 °, esihlanganiswe ne-magnetic agite ku-cartridge, ukuze uthole amaminerali, ukugoqa kanye nokushukuma kwama-magnetic, futhi ngaphansi kwesenzo samanzi okuhlanza, susa ngokwanele ukungcola kuma-concentrate, uthuthukise isikhundla se-Seiko.
■ Isakhiwo samaminerali sisetshenziselwa ukufeza ukugcwala kwamaminerali ngenkathi kusetshenziswa isakhiwo samaminerali.
Isihlukanisi SikaMagnetic Esiyinhloko se-JCTN
Izicelo
1. Isibonelo sokusetshenziswa kwe-magnetite eSichuan
I-Sichuan magnet mine fine particles, i-micro-deposited iron ore, inqubo yokukhiqiza yangempela iwucezu lokugaya olucwebezelayo -200 mesh 65%, ukukhethwa okubuthakathaka kwe-magnetic 1500GS coarse select - 1200GS select, iron concentrate TFE ingu-61.24%, futhi itholakala kuphela kuma-1200GS angaphezu kuka-1200, futhi izinga lokugxila lingakhushulwa libe ngu-63.16% kuphela, futhi ukubuyiswa kwensimbi kuncishiswe kakhulu.
Amakhasimende adinga ukuthi le mishini ikhethwe ukuze isetshenziswe ekugxilweni kwensimbi okuqinile, futhi ahlole ukugaya kwemishini ukuze afinyelele izidingo zekhwalithi yokugxila ezingaphezu kuka-66%.
Esivivinyweni, i-concentrating magnetic separator 1200GS isetshenziswe kuma-TFE grades. I-concentrate TFE eyaphumela yayingu-61.83%, kanti umkhiqizo we-TFE wawungu-63.45% ku-concentrate etholiwe. 2.55% kusuka ku-66%.
Thatha ukugxila kokuqala ngokusebenzisa i-mesh engu-160 kanye nokuhlolwa kwe-mesh engu-200 ukuze uhlaziye isimo sensimbi.
Umphumela wokuhlaziywa kosayizi wezinhlayiya zemayini yokuqala yeThebula lokuqala
Ekuhlaziyweni kosayizi wezinhlayiya, kwatholakala ukuthi kunezinhlobo eziningi zezinto eziphilayo ensimbini eyinhloko, futhi kudingeka i-mortary kuya ku--160, amaminerali ensimbi nemithambo angafinyelela ukuhlukaniswa okwanele kwe-monomer. Thatha i-ore yokuqala yokucwenga insimbi kuze kube yi--160, ngokulandelana, izingxenye ze-magnetic selection 1200GS kanye ne-JCTN refine desessment magnetic selection machine 3000 GS magnetic ziyaqhathaniswa, futhi imiphumela yokuhlolwa imi kanje:
Imiphumela yokuqhathanisa ukukhethwa kwamandla kazibuthe ematafuleni amabili
| Izimo zokuhlola | Igama lomkhiqizo | Veza% | Ukunambitha kwe-TFE% | Izinga lokutakula le-TFE% |
| -160 Isihlukanisi Esijwayelekile Se-Magnetic Se-Mesh 1200Gs | Ukugxila kwensimbi | 88.45 | 65.32 | 94.14 |
| Ukuthunga | 11.55 | 31.17 | 5.86 | |
| Imayini yokuqala | 100.00 | 61.38 | 100.00 | |
| -160 Mesh JCTN-3000Gs | Ukugxila kwensimbi | 88.19 | 68.60 | 97.67 |
| Ukuthunga | 11.81 | 12.23 | 2.33 | |
| Imayini yokuqala | 100.00 | 61.94 | 100.00 |
Ubukhulu bokuqala bokugaya bufika ku--160 bungu-65.32% we-TFE egxilile. I-JCTN ikhethwe kusuka ku-68.60%, kanti izinga kanye nezinga lokubuyisa liyi-3.28% kanye ne-3.50% ngokulandelana.
Ngokuphendula uhlobo lwe-lamination encane yemayini kamagnet eSichuan, isilingo sinqunyiwe - ukukhetha okuqinile - Ukugaya kabusha okuqinile - Inqubo yokuzikhethela kamagnethi ye-JCTN Substance Damage isetshenziswa ekukhiqizweni kwangempela, okwamanje, isitshalo sokusabalalisa. Ukunambitheka kwe-TFE okungakhethwa ngumagnetic kuzinzile ngaphezu kwama-68%, futhi ukululama kufana nesibonakaliso sokuhlola, kanye nodumo olukhulu lwekhasimende.
