I-CTDG ewuchungechunge unomphela isihlukanisi sikazibuthe esomile sikazibuthe sisetshenziswa kabanzi ukujikijela i-ore enobukhulu bezinhlayiyana ezingaphezu kuka-20 mm.
Uzibuthe unomphela isihlukanisi kazibuthe eyomile isetshenziswa kabanzi ezimayini metallurgical nezinye izimboni, ungakwazi ukuhlangabezana nezidingo zezimayini ezinkulu, medium and amancane, esetshenziswa magnetic ngokwahlukana plant ore ochotshoziwe ngemva usayizi kuyizinhlayiyana esiphezulu akuyona ezingaphezu kuka 500 mm impahla pre-ukugxila, ukulahla idwala lemfucuza exubile, ukubuyisela ibanga le-geological, kungasindisa amandla futhi kunciphise ukusetshenziswa, kuthuthukise amandla okucubungula embonini yokucubungula;
Isetshenziswe ku-stope, ingabuyisa i-magnetite edwaleni lemfucuza, ithuthukise izinga lokusebenzisa izinsiza ze-ore; Isetshenziselwa ukubuyisela insimbi yensimbi kusuka ku-steel slag; Isetshenziselwa ukulahla udoti nokuhlunga izinsimbi eziwusizo.
Uzibuthe unomphela isihlukanisi kazibuthe esomile ikakhulukazi sisebenzisa ukuhlukaniswa kazibuthe, insimbi ngokulinganayo ebhandeni, ngesivinini esingaguquki ukuya engxenyeni engenhla yesigubhu sikazibuthe, ngaphansi komphumela wamandla kazibuthe, amaminerali anamandla kazibuthe adsorb ebusweni bebhande likamagnetic roller, gijima kuya phansi kwesigubhu nangaphandle kwenkundla, thembela kumandla adonsela phansi ukuze ugxilise indawo, idwala elilahlwayo kanye namaminerali abuthaka kazibuthe angeke kube amandla kazibuthe okumunca nokugcina inertia yawo enyakazayo, isicaba kwesokunxele ukuya ngaphambili kwesihlukanisi se-ore ku-tailings slot.
Ngokombono wesakhiwo, isihlukanisi esihlala unomphela sikazibuthe esivimba uzibuthe sihlanganisa ikakhulukazi ukushayela, ukuhlanganisa iphinikhodi yensika enwebekayo, isinciphisi sokushayela, ukuhlanganisa isilayidi esiphambanayo, ukuhlanganiswa kwe-roller kazibuthe kanye nesinciphisi sokulungiswa kwesistimu kazibuthe nezinye izingxenye.
Amaphuzu abalulekile obuchwepheshe besakhiwo
1. ngosayizi omkhulu kunawo wonke ku-400 ~ 125 mm imikhiqizo echotshoziwe ewugqinsi yomile ngenxa yobukhulu bezinhlayiyana ze-ore, ukuchotshozwa okuqinile ngemuva kwebhande, i-bue emnyangweni webhande kulindeleke ukuthi ingene endaweni yokuhlukanisa imigqomo, nongqimba oluqinile lwe-cast ukuze kuzuzwe. okunengqondo imfucuza umphumela, ukunciphisa tailings of kokuqukethwe zensimbi kazibuthe, lesi sigaba isigubhu kazibuthe ukujula kazibuthe kudingeka sibe ezinkudlwana, ukwenza izinhlayiya ezinkulu ore ukubamba, isakhiwo isigaba somkhiqizo ubuchwepheshe amaphuzu ayinhloko: (1) sigubhu ububanzi, enkulu kuba ngcono, ngokuvamile 1 400 mm noma 500 mm.
(2) Ububanzi bebhande bubanzi ngangokunokwenzeka. Ubukhulu bobubanzi bomklamo webhande elikhethiwe okwamanje buyi-3 000 mm;
Ibhande lide ngangokunokwenzeka esigabeni esiqondile eduze kwekhanda lesigubhu, ukuze ungqimba lwempahla olungena endaweni yokuhlunga lube luncane.
(3) Ukuze uthole ukujula okukhudlwana kokungena kazibuthe, ukuthatha izinhlayiya zensimbi ezinobukhulu obukhulu bokuhlunga obungu-300 ~ 400 mm njengesibonelo, amandla kazibuthe ebangeni lika-150 ~ 200 mm ukusuka phezu kwesigubhu ngokuvamile makhulu 64kA/m, njengoba kukhonjisiwe kuMfanekiso 1 kanye neThebula 1.
(4) Ukuvunyelwa phakathi kwepuleti nesigubhu kukhulu kuno-400 mm, futhi kungalungiswa.
(5) Isivinini esijikelezayo sesigubhu singalungiswa, ngokulungiswa kwe-Angle yesimemezelo sikazibuthe kanye nokulungiswa kwedivayisi ehlukanisayo yezinto ezibonakalayo, ukuze inkomba yokuhlunga ibe sezingeni eliphezulu.
