Icyondo kibisi ni uruvange rwifu yamazi namazi yakozwe mugihe cyo gutema no gusya marble na granite. Uturere twinshi mumajyaruguru yigihugu cyacu ni ibirindiro byingenzi byo gutunganya amabuye, kandi ibyondo byinshi byibyatsi bikozwe buri mwaka, kandi kubitondekanya bifata hejuru yubutaka bunini bwumutungo wubutaka. Ifu yamabuye ifite imiterere myiza kandi biragoye kujugunya.Biroroshye kuguruka mwijuru mumuyaga mwinshi, kandi bitemba mumigezi hamwe namazi yimvura muminsi yimvura, bigatera umwanda mwinshi ibidukikije.
Amabuye y'agaciro ya gangue mubyondo birimo feldspar, quartz, calcite, dolomite, amphibole, nibindi. Amabuye y'agaciro yibanze hamwe numwanda harimo silikate yicyuma nka mashini, magnetite, okiside yicyuma, pyrite, na biotite. Kugeza ubu, ikoreshwa ryuzuye. uburyo bwo kubona ibyondo ni ugukora amatafari ya beto ya beto no gukora ibikoresho bya ceramic nyuma yo gukuraho umwanda.Iyambere ifite ubushobozi bunini bwo gutunganya naho iyindi ifite inyungu nyinshi mubukungu.
Ubushakashatsi bw'inyungu
Muri iyi ngingo, ubushakashatsi bwimbitse bwo gukoresha no kugirira akamaro burakorwa kubaserukira babonye ibyondo mu gace ka Jining. Amabuye y'agaciro mu byondo byabonetse ni feldspar, ibyuma bya mashini, ibyuma bya magneti, nibindi, kandi umwanda wangiza ni limonite, biotite, muscovite, calcite, dolomite, hornblende, nibindi. Ubunini bwibintu ntiburinganiye, uduce duto duto turi hagati ya 1-4mm na bimwe -0.037mm icyondo cyiza.Muri bo, ibyuma bya mashini byakozwe mugihe cyo gutunganya hamwe nicyuma cya magneti mubibisi ubutare burashobora gutandukanywa muburyo bwa magneti mubicuruzwa byibanda cyane.Nyuma yo gutandukana gukomeye kwa magneti, umwanda urimo fer nka limonite, biotite, na amphibole urashobora kuvaho.Ibicuruzwa byibanda ku mabuye, buri gice cyumurizo wa magneti kirashobora gukoreshwa nkamatafari ya gaz cyangwa ibikoresho bya sima, kugirango bigere ku ntego yo kubikoresha byuzuye.
1.Kugena inzira
Gukomatanya imiterere yicyitegererezo cyibiti kugirango umenye inzira yo kugirira akamaro: ubutare mbisi butoborwa binyuze muri meshes 30- + 30 mesh coarse-ingano gusya kugeza -30 mesh
——-30 mesh ivanze nicyitegererezo cyo gutandukanya icyuma gitandukanya ingoma + isahani iringaniye + impeta ihagaritse + impeta ihagaritse ikomeye ya magnetiki yo gukuramo-intumbero ishyirwa mubice +300 mesh hagati yintete ya feldspar yibicuruzwa hamwe na -300 mesh icyondo cyiza——Amashanyarazi meza noneho akoreshwa mugukuraho ibyuma inshuro ebyiri binyuze mumashanyarazi ya elegitoronike kugirango ubone ibicuruzwa byiza byo murwego rwohejuru.
2.Ikizamini cyo gutandukanya amabuye y'agaciro
Amabuye mbisi yashizwemo na meshes 30, kandi ibisubizo byisesengura bigaragara mu mbonerahamwe ya 1.
Imbonerahamwe 1. Ibisubizo byunguka no Kwipimisha
Gusya amabuye yuzuye intete hamwe n'umusaruro wa 17.35% kugeza kuri 30 mesh, ukavanga nibicuruzwa munsi yicyuma, hanyuma unyure muburyo busanzwe bwo gutandukanya magnetiki yo gutandukanya ingoma + isahani iringaniye + impeta ihagaritse + impeta ihagaritse.Inzira igenda irerekanwa mumashusho 1, naho ibisubizo byikizamini bigaragara mu mbonerahamwe ya 2.
Igicapo 1. Inzira yo gutembera bisanzwe ya magnetiki yo gutandukanya amabuye y'agaciro.
Imbonerahamwe 2. Ibisubizo byikizamini gisanzwe cyo gutandukanya magnetiki
Amabuye mbisi arasuzumwa + gusya amabuye + inshuro eshatu zose zo gukuraho ibyuma bisanzwe, kandi ibicuruzwa byo hagati hamwe nu munsi wo hasi birashobora kuboneka hamwe n'umusaruro wa 92.57%, Fe2O3 irimo 0.525% naho umweru wa 36.15%. Byakagombye gutekerezwaho kweza okiside nziza ya fer na silikatike yicyuma mubyondo byiza hamwe na mashini nziza, yumurima muremure wa electromagnetic slurry nyuma yo gutondekanya.
3.Iron ikurwa mubyondo byiza
Ihuriro rya kabiri rya Lihuan risohorwa mumashanyarazi meza munsi ya -300 meshi yuzuye, kandi inzira yo gukuramo ibyuma kabiri na mashini ya electromagnetic ikoreshwa muburyo bwo kubona ifu nziza.Inzira igenda igaragara ku gishushanyo cya 2, naho ibisubizo byikizamini bigaragara mu mbonerahamwe ya 3.
Igishushanyo 2. Inzira yo gutembera neza icyondo cyo gukuramo ibyuma
Imbonerahamwe 3. Icyerekezo cyo gukuraho ibyuma byerekana ibyondo byiza
Nyuma yo gutondekanya intumbero ya Lihuan, umweru wa +300 mesh yo hagati ya feldspar intungamubiri wiyongereye uva kuri 36.15% ugera kuri 56.49%, naho umweru wibyondo byiza wagabanutse ugera kuri 23.07%.-300 mesh nziza yamashanyarazi ikurwa mubyuma kabiri na electromagnetic slurry, hamwe na ceramic yo mu rwego rwa ceramic nziza yifu ya 42.31% naho umweru wa 41.80% urashobora kuboneka.
3.Ikizamini cyose
Ibizamini byuzuye hamwe nibipimo byo gukora ikizamini cyose.
Igicapo 3. Inzira yose yo kubona ibyondo byo gupima ibyondo
Imbonerahamwe 4. Ibipimo byerekana ibizamini byose
Umugereka: Biscuits ubushyuhe 1200 ℃
Amabuye y'icyondo yacukuwe + hasi + itandukanya imbaraga za magneti + isahani iringaniye + impeta ihagaritse + impeta ihagaritse + itondekanya amashanyarazi ya magnetiki itandukanya kugirango ibone ubutare bwa fer hamwe n'umusaruro wa 0.32% hamwe na TFe ya 62.35%.Hamwe n'umusaruro wa 38.56% naho umweru wa 54,69% wibicuruzwa bito bito bya ceramic yo mu bwoko bwa feldspar yibicuruzwa hamwe numusaruro wa 42.31% byera bya 41.80% byifu ya ceramic yo mu rwego rwo hejuru;umusaruro wose wumurizo wa magneti ni 18.81%, Urashobora gukoreshwa nkibikoresho fatizo byamatafari.
Ubu buryo bwikoranabuhanga butuma hakoreshwa neza umurizo w’ibyondo, kandi birashobora kubona inyungu zubukungu n’akamaro ko kurengera ibidukikije.
