I-Saw udaka ngumxube womgubo wamatye kunye namanzi avelisiweyo ngexesha lokusikwa kunye nokupholiswa kwemarble kunye negranite.Iindawo ezininzi ezisenyakatho yelizwe lethu ziyiziseko ezibalulekileyo zokulungiswa kwamatye, kwaye inani elikhulu lodaka lwesarha luveliswa minyaka yonke, kwaye ukupakishwa kwayo kuthatha. phezulu indawo enkulu yobutyebi bomhlaba.I-powder yamatye inesicatshulwa esihle kwaye kunzima ukuyilahla. Kulula ukubhabha esibhakabhakeni kumoya onamandla, kwaye uqukuqela usiya emlanjeni unamanzi emvula ngeentsuku zemvula, okubangela ungcoliseko olukhulu lokusingqongileyo.
Iiminerali eziphambili ze-ganggue kwi-saw mud ziquka i-feldspar, i-quartz, i-calcite, i-dolomite, i-amphibole, njl. Izimbiwa eziphambili zetsimbi kunye nokungcola zibandakanya i-silicate yensimbi efana ne-iron mechanical, i-magnetite, i-iron oxide, i-pyrite, kunye ne-biotite. Okwangoku, ukusetyenziswa okubanzi indlela yodaka isarha ikakhulu ukuvelisa izitena aerated ikhonkrithi kunye nokwenza izixhobo zeceramic ekrwada emva kokususa ukungcola. Eyangaphambili inomthamo omkhulu wokucubungula kwaye le yokugqibela ineenzuzo eziphezulu zoqoqosho.
Uphando lwenzuzo
Kule nqaku, uphando olubanzi lokusetyenziswa kunye novavanyo lwe-beneficiation lwenziwa kummeli wabona udaka kwindawo ye-Jining.Izimbiwa ezixabisekileyo kwi-saw mud yi-feldspar, isinyithi somatshini, isinyithi samagnetic, njl., kunye nokungcola okuyingozi yi-limonite, biotite, i-muscovite, i-calcite, i-dolomite, i-hornblende, njl njl. Ubungakanani bezinto eziphathekayo abulingani, iinqununu ezinqabileyo zivela kwi-1-4mm kunye nezinye -0.037mm zodaka oluhle. Phakathi kwazo, isinyithi somatshini esiveliswa ngexesha lokucubungula kunye nentsimbi yamagnetic kwindawo eluhlaza. Intsimbi ekrwada inokohlulwa ngokwemagnethi ibe yimveliso yentsimbi. Emva kokuhlukana okunamandla kwamagnetic, ukungcola okunentsimbi okufana ne-limonite, i-biotite, kunye ne-amphibole inokususwa. Iimveliso ze-Stone concentrate, icandelo ngalinye le-magnetic tailings linokusetyenziswa njengezitena ezine-aerated okanye izinto zesamente, ukuze kuphunyezwe injongo yokusetyenziswa ngokubanzi.
1.Ukumiselwa kwenkqubo yokuhamba
Ukudibanisa iipropathi zesawdust yesampulu ukumisela inkqubo yoncedo: intsimbi ekrwada ekrwada ihluzwa ngeeminatha ezingama-30-+30 umnatha orhabaxa-oziinkozo ukucola ukuya kwi-30 mesh.
—--30 umnatha oxubeneyo wesampulu yentsimbi yokwahlulwa ngegubu lokwahlulahlula kazibuthe + ipleyiti ecaba + umsesane othe nkqo + umsesane othe nkqo oqinileyo wokususwa kwentsimbi enozibuthe-ugxininiso luhlelwa ngokwe +300 umnatha ophakathi kweenkozo eziziinkozo zefeldspar kunye ne-300 mesh yodaka oluhle.—-Udaka olucolekileyo luthi ke lusetyenziswe ukususa intsimbi kabini ngodaka lwe-electromagnetic ukufumana imveliso yoxinaniso yodidi lomgubo.
2.Uvavanyo lokwahlulwa kwentsimbi ekrwada
I-ore ekrwada yahluzwa nge-30 meshes, kwaye iziphumo zohlalutyo ziboniswe kwiThebhile 1.
Itheyibhile 1. Iziphumo zeNzuzo kunye noVavanyo lokuHlola
Gaya i-ore ecoarse-grained kunye nesivuno se-17.35% ukuya kwi-30 mesh, xuba kunye nemveliso phantsi kwe-sieve, kwaye uhambe kwinkqubo yokwahlulwa kwemagnethi eqhelekileyo ye-drum magnetic separator + flat plate + ring ring + ring ring. Ukuhamba kwenkqubo kuboniswe kuMfanekiso 1, kwaye iziphumo zovavanyo ziboniswa kwiThebhile 2.
Umzobo 1. Ukuhamba kwenkqubo yovavanyo oluqhelekileyo lokwahlula kwamagnetic ore ekrwada.
Itheyibhile 2. Iziphumo zovavanyo oluqhelekileyo lokuhlukana kwamagnetic
I-ore ekrwada ihlolwe + i-ore yokusila + inkqubo yovavanyo oluqhelekileyo lokususa isinyithi kathathu, kwaye imveliso ephakathi kunye nesezantsi-ephantsi ingafumaneka ngesivuno se-92.57%, umxholo we-Fe2O3 we-0.525% kunye nomhlophe we-36.15%. Kufuneka kuthathelwe ingqalelo ukuhlambulula i-oxide yentsimbi ecolekileyo kunye nentsimbi ye-silicate eludakeni oluhle kunye nomatshini ophakathi, ophezulu we-electromagnetic slurry machine emva kokuhlelwa.
3.Ukususwa kwentsimbi kudaka olucolekileyo lodaka
I-concentrate yesibini ye-Lihuan ikhutshwe kwi-sludge emihle engaphantsi kwe-300 mesh ngokuphuphuma, kunye nenkqubo yokususa isinyithi kabini ngomatshini we-electromagnetic slurry isetyenziselwa ukufumana imveliso ye-powder concentrate. Ukuhamba kwenkqubo kuboniswe kuMfanekiso 2, kwaye iziphumo zovavanyo ziboniswe kwiThebhile 3.
Umfanekiso 2. Inkqubo yokuhamba yovavanyo lokususa intsimbi yodaka olucolekileyo
Itheyibhile 3. Isalathiso sokususa intsimbi yodaka olucolekileyo lodaka
Emva kokuhlelwa kwe-concentrate ye-Lihuan, ubumhlophe be-+300 mesh medium-grain-grain-feldspar concentrate inyuke ukusuka kwi-36.15% ukuya kwi-56.49%, kwaye ubumhlophe bodaka olucocekileyo lwehla ukuya kwi-23.07%. -I-300 i-mesh i-sludge ecocekileyo isuswe kwintsimbi kabini nge-slurry ye-electromagnetic, kunye nemveliso ye-ceramic-grade ye-powder ecocekileyo kunye nesivuno se-42.31% kunye nobumhlophe be-41.80% inokufumaneka.
3.Uvavanyo lwenkqubo yonke
Iimeko zovavanyo olubanzi kunye nezalathi zokwenza uvavanyo lwenkqubo yonke.
Umzobo 3. Yonke inkqubo yokubona inkqubo yovavanyo lodaka
Itheyibhile 4. Iimpawu zovavanyo zenkqubo yonke
I-Attachment: Ubushushu beebhiskithi 1200℃
Intsimbi ekrwada yodaka esabonwayo iyahluzwa + emhlabeni + ulwahlulo olubuthathaka lwemagnethi + ipleyiti ecaba + umsesane othe nkqo + umsesane othe nkqo + ukulinganisa inkqubo yokwahlulwa koludaka lwe-electromagnetic magnetic ukufumana intsimbi ekrwada ngesivuno se-0.32% kunye nebakala leTFe lama-62.35%. Ngesivuno se-38.56% kunye nobumhlophe be-54.69% ye-medium-grain-grain grade feldspar concentrate products kunye nesivuno se-42.31% yobumhlophe be-41.80% yeemveliso ze-concentrate yodidi lwe-ceramic grade; isivuno esipheleleyo se-magnetic tailings yi-18.81% , Ingasetyenziswa njengento ekrwada kwizitena ezifakwe umoya.
Le nkqubo yobuchwepheshe ivumela ukusetyenziswa okubanzi kweentsalela zodaka, kwaye inokufumana inzuzo ephezulu yezoqoqosho kunye nokubaluleka kokhuseleko lwentlalo.
