Icuma gishongeshwa, nk'imyanda ya nyuma ikorwa no gushongeshwa kw'icyuma, irimo ibintu byinshi by'icyuma. Bitewe n'ubucucike bwayo bwinshi n'ubucucike bwayo bwinshi, ntishobora gukururwa no gukoreshwa mu nganda z'ubwubatsi. Umutungo w'icyuma cy'agaciro ntabwo wabonetse neza, bigatuma habaho ingano runaka y'imyanda. Icuma gishongeshwa kigomba kongera gukoreshwa no kongera gukoreshwa binyuze mu nzira runaka yo gutandukanya ibyuma, kandi kikujuje ibisabwa by'urwego rw'icyuma gisabwa n'ibikoresho birimo icyuma mu gushongeshwa kw'itanura, kugira ngo icuma gishongeshwe. Gishobora gukoreshwa neza mu bwubatsi.
Muri iki gihe, inzira runaka yo gutandukanya ibyuma ni uburyo bushoboka, kandi ni ngombwa guhitamo ibikoresho bikwiye kugira ngo icyuma gitandukanye kandi gikoreshwe neza. Ifu y'icyuma irasya kugira ngo itandukane, hanyuma binyuze mu kirere, ifu y'amabuye yumye, ifu y'amabuye n'ibiyikomokaho byakirwa, kandi urwego rw'icyuma cyose rurasesengurwa kandi rugasesengurwa kugira ngo haboneke ibipimo byiza by'imikorere n'ibikoresho. Tanga inkunga ikwiye mu bya tekiniki kugira ngo hakorwe umusaruro nyawo.
Imiterere y'icyuma gikozwe mu byuma
Ifu y'icyuma ni ifu y'imyanda ikorwa hakoreshejwe ifu irimo magnesiyumu nyinshi, ifu y'imyanda n'ibindi bikoresho by'inyongera mu gukuraho ubwandu no guhumeka ogisijeni mu buryo bwo gukora ibyuma, bityo ikaba irimo okiside y'icyuma nyinshi, muri rusange 20%-40%, kandi ingano ya FeO irenze Fe2O3, iya mbere muri rusange ni 15%-25%, mu gihe iya nyuma ari 5%-15%, byombi bigaragaza imbaraga nke zo gukoresha.
Ibikoresho byo gupima
Ibikoresho byo gupima bikoresha FX0665 powder ore air dry magnetic separator ya Huate Company, ikoreshwa cyane cyane mu guhitamo magnetite mbere yo kuyisya cyangwa gukora concentrate yujuje ibisabwa ivuye muri magnetite ifu.
Igitandukanya cy'amabuye y'agaciro cyumye mu mwuka gikoresha amashanyarazi
Ihame ry'imikorere
igikonoshwa cyo hejuru 2. Gutumanaho 3. Umwobo wo kugaburira 4. Umugozi wa magnetiki 5. Aho gusohokera ivumbi 6. Igikoresho gifata umwuka 7. Igikoresho cyo guhongerera umuyaga 8. Ishusho 9. Ifungura ry'imirizo 10. Ifungura ry'umuvuduko
igikonoshwa cyo hasi
Ihame ry’imikorere ry’imashini igabanya ubushyuhe bw’umwuka ikoresheje ifu y’amabuye y’agaciro igaragara ku ishusho. Amabuye y’agaciro agezwa ku buso bw’ingoma ya rukuruzi binyuze mu mwanya wo kugaburira amabuye y’agaciro 3, maze amabuye y’agaciro agatembera ku buso bw’ingoma ya rukuruzi 4 binyuze mu bikorwa by’imbaraga za rukuruzi, hanyuma agazunguruka n’ingoma ya rukuruzi 4. Muri iki gikorwa, amabuye y’agaciro ari ku buso bw’ingoma ya rukuruzi 4 ashyirwa mu bikorwa bya rukuruzi by’inguni nini n’inkingi nyinshi za rukuruzi, igikoresho cyo gukurura rukuruzi, igikoresho cyo kwinjiza umwuka 6 n’umwanya wo gukuraho ivumbi 5, kugira ngo imyanda iri mu mabuye y’agaciro n’ibinyabuzima bifatanye nabi biveho neza. Bityo, urwego rw’umusaruro rurushaho kuba rwiza. Nyuma y’uko amabuye y’agaciro yatoranijwe azungurutswe mu gace katari gakuruzi hamwe n’ingoma ya rukuruzi 4, ashyirwa mu mwanya wo gukurura 9 binyuze mu bikorwa by’imbaraga rukuruzi, imbaraga za centrifugal n’igikoresho cyo gupakurura kugira ngo abe umukungugu. Imyunyu ngugu idakoresha rukuruzi cyangwa imibiri ifatanye idafite imbaraga nyinshi ivanwa mu kanwa k'imiyoboro y'amazi bitewe n'imbaraga rukuruzi n'imbaraga zo hagati, maze igahinduka imiyoboro y'amazi cyangwa amabuye y'agaciro aciriritse.
Udushya n'ikoranabuhanga ry'ingenzi ryo gutandukanya ifu y'amabuye y'agaciro mu mwuka wumisha magnetic
1. Akamashini gatuma umuntu anyeganyega gakoreshwa mu kugaburira, kandi ibipimo by'akamashini gashobora guhindurwa kugira ngo gashobore kugaburira kimwe;
2. Sisitemu ya rukuruzi ikoresha imiterere y’inkingi nyinshi, inguni nini yo gupfunyika (kugeza kuri dogere 200-260), imbaraga nyinshi zo mu butaka (3000-6000Gs), kandi imiterere ya sisitemu ya rukuruzi ishobora guhinduka bitewe n’imiterere y’amabuye y’agaciro kugira ngo haboneke ibipimo by’ubuziranenge bukwiye;
3. Umuvuduko w'umuyoboro wa silindiri uhinduka hagati ya 1-20m/s, kandi umuvuduko ukwiye urashobora gutoranywa hakurikijwe imiterere y'amabuye y'agaciro; silindiri ikozwe mu bikoresho bitari iby'icyuma kandi ifite igikoresho gikurura amashanyarazi kugira ngo cyongere urwego rw'umuvuduko;
4. Ifite imiterere yihariye y'icyuma gikoresha umwuka, igikoresho gikuraho umuyaga n'igikoresho gikuraho umukungugu (ibipimo bikwiye bishobora gutoranywa hakurikijwe imiterere n'ibisabwa ku gipimo cy'amabuye); hejuru y'icyuma cy'ubutare hashyizweho igikoresho cyo gupakurura, gishobora gutuma amazi asohoka neza;
Igikoresho cyo gutandukanya amashanyarazi cy'ifu y'ubutare bw'umwuka cya FX kigizwe ahanini n'igikoresho gitanga amakuru, ingoma yo gutandukanya amashanyarazi, igikoresho cyo gusohora ivumbi, igikoresho cyo gukusanya imirasire, nibindi. Imbaraga za rukuruzi z'ingoma yo gutandukanya amashanyarazi ni 3500Gs. , imbaraga za rukuruzi, imbaraga za centrifugal zizenguruka, nibindi, bishobora kugera ku guhitamo magnetite yumye mbere yo gupima utunyangingo twa 0-5mm cyangwa kongera cyane urwego rwa magnetite y'ifu nziza. Ingaruka nyamukuru ni izi zikurikira:
A. Ingano ya magnetite ya 0-5mm ishobora kongerwa kuva kuri 10% ikarenga 40%. Ishobora gukoreshwa mbere yo kuyikuraho mbere yo kuyisya, ibi bikaba bishobora kunoza cyane ingano y’inganda zinjiramo no kunoza imikorere y’urusyo.
B. Ingano yatoranijwe ya -74um na -45um magnetite nziza ishobora kongerwa kuva kuri 10% ikarenga 60%, kandi ifumbire yujuje ibisabwa ishobora kuboneka mu buryo butaziguye hakoreshejwe uburyo bwumye.
