I-Magnet ore ineempawu ezinamandla zemagnethi, ikakhulu eziquka i-single magnet ore, i-vanadium titanium magnet ore, i-magnetite kunye ne-iron oxide mixed ore, i-magnetite multi-metal symbiotic ore, njl. I-magnetite yahlulwe yaba zii-granules ezirhabaxa, ii-medium fine particles, ii-fine particles kwi-magnetite, apho umgodi wesinyithi ogcinwe kwiinkozo ezirhabaxa kunye nee-medium fine particles uyaphuka. Emva kwenkqubo yoku-murrization, inokufumana i-iron concentrates ezifanelekileyo ngenkqubo yokukhetha i-magnetic ebuthathaka. Umgodi wemagnethi we-Micronardized udinga i-fine mill ukuya kwi-monomer eyaneleyo ukuze kufezekiswe izalathisi zokusasazwa ezingcono.
Isisombululo se-JCTN somjelo wokuhambisa amanzi owenziwe ngemagnethi iWalt sisixhobo sokwahlulahlula imagnethi esimanzi sokuhlamba nokucoca imigodi yemagnethi, esifanelekileyo ekuhleleni imveliso yokugcwala kwe-milling grading; kunye noxinzelelo lweminerali ngaphambi kokuhluza; imagnetiti ingena kwisihluzo esingaphambi kwesihluzo esihlolwe ngaphambi kokuhluza; ukhetho lokugqibela lwemagnethi kunzima ukuphucula amasuntswana amancinci okhetho lwemagnethi oluqhelekileyo, amasuntswana amancinci, i-iron ore inefuthe elikhulu lokukhetha.

Iimpawu zobugcisa eziphambili
■ Ukubopha kwi-mineral kunye ne-overflow coincidence kusetyenziswa ukufezekisa injongo yokwemba okufanayo;
■ Ukusetyenziswa kohlobo olutsha lomzimba we-groove ongenalandelelwano kunye nokujikeleza okujikelezayo kwe-roller kunokuphucula ukubuyiswa kweeminerali;
■ Kubonelelwa ngesakhiwo sokuhlamba esinamanqanaba amaninzi kunye nesakhiwo sekhethini yamanzi ephezulu kwi-groove entsha engenalandelelwano, enokuhlamba ngokupheleleyo iiminerali kumphezulu wedrama;
■ Thatha isakhiwo semagnethi esikhulu esingama-240 ° -270 ° esiquka isakhiwo semagnethi esine-multi-magnetic pole, esidityaniswe ne-magnetic agite kwikhatriji, ukuze ufumane iiminerali, ukuqengqeleka kunye nokushukuma kwemagnethi, kwaye phantsi kwesenzo samanzi okuhlamba, susa ngokwaneleyo ukungcola kwi-concentrates, uphucule isikhundla seSeiko.
■ Ulwakhiwo lweminerali lusetyenziselwa ukufikelela kuxinzelelo lweeminerali ngelixa kusetyenziswa ulwakhiwo lweminerali.

Izicelo
1. Umzekelo wokusetyenziswa kwemagnetite eSichuan
Imagnethi yaseSichuan igrumba amasuntswana amancinci, i-ore yesinyithi egcinwe kwi-micro-deposited, inkqubo yokwenyani yemveliso sisiqwenga sokugaya esincinci -200 mesh 65%, ukhetho olubuthathaka lwemagnethi 1500GS ukhetho oluqinileyo - ukhetho lwe-1200GS, i-iron concentrate TFE yi-61.24%, kwaye ifumaneka kuphela ngaphezulu kwe-1200GS, kwaye umgangatho we-concentrate unokwandiswa kuphela ukuya kwi-63.16%, kwaye ukubuyiswa kwesinyithi kuncitshiswe kakhulu.
Abathengi bafuna ukuba ezi zixhobo zikhethwe kwi-iron coarse concentrate ekhethiweyo, kwaye baphande ngokusila kwe-mill ukuze bafezekise iimfuno zomgangatho we-concentrate ezingaphezulu kwama-66%.
Kolu vavanyo, i-concentrate magnetic separator 1200GS isetyenzisiwe kwiindidi ze-TFE. I-concentrate TFE ephumezileyo yayiyi-61.83%, kwaye imveliso ye-TFE yayiyi-63.45% kwi-concentrate efunyenweyo. 2.55% ukusuka kwi-66%.
Thatha i-concentrate yokuqala nge-160 mesh kunye ne-200 mesh screening ukuze uhlalutye imeko yesinyithi.
Itheyibhile yokuqala iziphumo zohlalutyo lobungakanani bamasuntswana omgodi wokuqala
Kuhlalutyo lobungakanani bamasuntswana, kwafunyaniswa ukuba kukho izinto eziphilayo ezininzi kwisinyithi esiphambili, kwaye i-mortary ukuya kwi--160 yayifuneka, iiminerali zesinyithi kunye nemithambo zinokufikelela ekuhlukaniseni okwaneleyo kwe-monomer. Thatha i-ore yokucokisa isinyithi yokuqala ukuya kwi--160, ngokulandelanayo, umatshini wokukhetha i-magnetic selection 1200GS kunye nomatshini wokukhetha i-magnetic refine desessment 3000 GS magnetic segments ziyathelekiswa, kwaye iziphumo zovavanyo zezi zilandelayo:
Iziphumo zothelekiso lokukhethwa kwemagnethi yemigodi emibini yemigodi
| Iimeko zovavanyo | Igama lemveliso | Yima kancinci% | Incasa yeTFE% | Izinga lokubuyisa i-TFE% |
| -160 Mesh Regular Magnetic Separator 1200Gs | I-iron concentrate | 88.45 | 65.32 | 94.14 |
| Iintsila | 11.55 | 31.17 | 5.86 | |
| Imayini yoqobo | 100.00 | 61.38 | 100.00 | |
| -160 Mesh JCTN-3000Gs | I-iron concentrate | 88.19 | 68.60 | 97.67 |
| Iintsila | 11.81 | 12.23 | 2.33 | |
| Imayini yoqobo | 100.00 | 61.94 | 100.00 |
Ubukhulu bokuqala bokugaywa ukuya kwi--160 yi-65.32% ye-TFE egxininisiweyo. I-JCTN ikhethwe kwi-68.60%, kwaye izinga kunye nomlinganiselo wokubuyisela yi-3.28% kunye ne-3.50%, ngokulandelelana.
Ukuphendula uhlobo lwe-lamination encinci yomgodi wemagnethi eSichuan, uvavanyo luye lwafumanisa – ukhetho oluqinileyo – Ukugaya kwakhona okurhabaxa – Inkqubo yokukhetha imagnethi ye-JCTN Substance Damage isetyenziswa kwimveliso yokwenyani, okwangoku, kwisityalo sokusasaza. Incasa ye-TFE ekhethiweyo yemagnethi izinzile ngaphezulu kwe-68%, kwaye ukubuyiselwa kufana nesalathisi sovavanyo, kunye nendumiso ephezulu yomthengi.
