Isixhobo sokusila esithe nkqo sisixhobo esiyimfuneko nesibalulekileyo kwishishini lokulungisa umgubo, elisetyenziswa kakhulu kumashishini ahlukeneyo oqoqosho lwesizwe.Umzekelo, ishishini lemigodi ye-metallurgical.Intsimbi ekrwada igutyungelwa yintsimbi yokusila ethe nkqo, ize ihlolwe zizixhobo zebeneficiation ngaphambi kokungena kwinkqubo yokunyibilikisa, enokuphucula umgangatho wentsimbi enyibilikisiweyo kwaye inciphise ukusetyenziswa kwamandla kuyo yonke inkqubo yokunyibilikisa.I-HCMilling(Guilin Hongcheng), njengomvelisi wentsimbi yokusila intsimbi, yazisa olu setyenziso lulandelayo igoqo lentsimbiilitye lokusila elithe nkqo kwintsimbi ekrwada eyomileyo beneficiation.

Okwangoku, inkqubo yoncedo olumanzi isetyenziswa ikakhulu ekuphuculeni ibakala lentsimbi ekrwada.Amanyathelo enkqubo ami ngolu hlobo lulandelayo: emva kokuba i-ore ekrwada ityunyuziwe, i-slurry efanelekileyo kwi-beneficiation ilungiswa ngokugaya kwi-horizontal ball system.I-slurry ihlukaniswe kwi-beneficiation system ukuze yenze i-concentrate powder kunye nenqanaba eliphezulu lentsimbi kunye ne-tailings kunye ne-iron grade ephantsi.Inkqubo yokugaya i-slurry kunye nokunxiba kufuneka idle amanzi amaninzi, ngakumbi kwiindawo zomgodi ezingenayo imithombo yamanzi, ngoko ke ukugcinwa kwamanzi kunye nokusela amanzi kuba yingxaki enzima.Ukuze kuncitshiswe iingxaki ezikhankanywe ngasentla, ukugaya kunye nokuxhamla phantsi kwemeko yokungabikho kwamanzi okanye ukusetyenziswa kwamanzi okuncinci kuye kwaba yinjongo elandelwa ngabantu.Nangona kunjalo, okwangoku, yonke inkqubo yokugaya eyomileyo kunye neyomileyo yokwahlukana ayifane isetyenziswe ekusebenzeni.Ijolise kwingxaki yokusetyenziswa kwamanzi amakhulu kwinkqubo ekhoyo yokusila kunye ne-beneficiation ekhoyo, intsimbi yokusila ethe nkqo yentsimbi ibonelela ngenkqubo yentsimbi ekrwada eyomileyo: intsimbi ekrwada etyunyuziweyo igaywa ibe ngumxube wamasuntswana entsimbi kunye nomgubo wentsimbi ngowomileyo. igoqo lentsimbiilitye lokusila elithe nkqo;I-ore powder kunye namasuntswana ahlulwe nge-multistage ephakamisa isahluli somoya;Amasuntswana entsimbi ekrwada axhomekeke kulwahlulo lwemagnethi yamanqanaba ngamanqanaba ngamathuba amaninzi oxinaniso lwemagnethi ukuze lwahlule lube kudidi oluphezulu lokugxila, intsimbi ekrwada ephakathi yomgangatho jikelele kunye neentsalela zezimbiwa zodidi oluphantsi.Intsimbi ekrwada ephakathi ibuyiselwa kwisingqusho esithe nkqo somgodi wentsimbi ukuze sigaywe kwakhona.

Okwangoku, i-mill esetyenziswa ngokuqhelekileyo ngamashishini okucoca isinyithi emanzi ngokuqhelekileyo i-tube mill yendabuko, engadli kuphela imithombo yamanzi, kodwa iphinda isebenzise umbane omkhulu.I-iron ore vertical roller mill esetyenziswa kwi-iron ore dry beneficiation luhlobo olutsha lwelitye elinobugcisa obuphezulu bemveliso kunye nokusebenza okukhuselekileyo nokuthembekileyo.Isakhiwo sayo esiphambili siqulunqwe yimoto ephambili, i-reducer engundoqo, i-disc yokugaya, i-roller yokugaya kunye ne-tensioning kunye ne-pressurizing device, isakhelo, isahluli, amasango amathathu, ukufakwa kunye nokugcinwa kwesixhobo, isixhobo esincedisayo sokuqhuba kunye nokutywinwa kombhobho womoya.Xa kuthelekiswa ne-tube yokusila ye-beneficiation emanzi, iigoqo lentsimbiilitye lokusila elithe nkqoinezi ncedo zilandelayo:

(1) Ilitye lokusila elithe nkqo lentsimbi linemveliso ephezulu kwaye linciphisa kakhulu ukusetyenziswa kwamandla okusila.Xa kuthelekiswa ne-tube yokusila, ukusetyenziswa kwamandla ombane we-vertical roller yi-50% ~ 60% kuphela ye-ball mill, eyahluka kunye nomxholo womswakama wezinto eziluhlaza.Okukhona kuphezulu ukufuma, kokukhona ukonga ngakumbi.Ngokubanzi, ukusetyenziswa kwamandla elitye lokusila elithe nkqo lokusila isamente yi-20 ~ 25 kW · h/t, ngelixa lelo lokusila ityhubhu yemveli yi-40 ~ 45 kW · h/t, kunye nesiphumo esicacileyo sokugcina amandla.

(2) Ukomisa ngamandla.Umthamo omkhulu womoya oshushu ungasetyenziswa, ngakumbi ukuphinda kusetyenziswe inkunkuma yerhasi yobushushu obuphantsi ekupheleni kwe-PC okanye kwi-PH kiln.

(3) Inkqubo ilula, idibanisa ukutyumza, ukomisa, ukukhetha umgubo kunye nezinye iinkqubo, ukwenza lula inkqubo.Isixhobo sokusila esithe nkqo sisetyenziswa njengenkqubo yokugaya, kunye nesomisi kunye ne-powder concentrator kwinkqubo yokugaya ingasuswa.Ayigcini nje ukunciphisa utyalo-mali lwezixhobo, kodwa yenza lula inkqubo, yenza yonke inkqubo ikhuseleke ngakumbi kwaye ithembekile.

(4) Ulawulo olulula.Ixesha lokugcinwa kwezinto kwi-mill yi-2-3 min kuphela, ngelixa i-tube mill yi-15-20 min.Ngoko ke, inkqubo yokusebenza kulula ukuyitshintsha, ukubunjwa kweekhemikhali kunokulungiswa ngokukhawuleza, kwaye ukuhanjiswa kobungakanani bemveliso kufana.

(5) Ubungakanani be-particle ye-feed material inkulu, kwaye ubungakanani be-particle ye-feed ingafikelela kwi-4% ~ 5% ye-diameter roll.

(6) Ingxolo ephantsi.Ekubeni i-roller ye-vertical roller mill ayiqhagamshelani ngokuthe ngqo ne-disc yokugaya, ngelixa i-tube mill isebenzisa ibhola yokusila ukuze idibanise ngokuthe ngqo izinto eziphathekayo, akukho msindo wempembelelo yentsimbi, kwaye ingxolo yi-10 dB ephantsi kunombhobho. .

(7) Kukho ukuvuza komoya okuncinci.Isixhobo sokusila esithe nkqo sinomsebenzi olungileyo wokutywinwa jikelele kunye neseti “yenkqubo yokutywina yomoya”, ehamba phambili kwaye inokuthenjwa kunetywina elinomatshini wemveli, ngoko ke ilungele ukusetyenziswa kwerhasi yenkunkuma enobushushu obuphantsi.

(8) Izinga eliphezulu lokusebenza.I-vertical roller mill ineenzuzo zokusebenza okuphezulu kunye nokunxiba okuphantsi.Xa ugaya ukutya okukrwada, ukusetyenziswa kweengxenye zokugqoka ngokuqhelekileyo ku-6-8 g / t, kwaye ubomi benkonzo ye-roll sleeve kunye ne-lining plate inokufikelela ngaphezu kwe-8000 h.Xa i-tube yendabuko ye-tube isebenza, ibhola yokugaya kunye ne-abrasive idibanisa ngokuthe ngqo.Ibhola yokugaya kunye ne-lining plate inxiba ngokukhawuleza, izixhobo zitshintshwa rhoqo, kwaye izinga lokusebenza kwezixhobo liphantsi.Isantya sokusebenza kwelitye lokusila elithe nkqo lifikelela ngaphezulu kwama-90%.

I-HCMilling(Guilin Hongcheng) ngumvelisi wentsimbi yokusila ethe nkqo.YethuHLM series iron oreilitye lokusila elithe nkqo zisetyenziswe ngokubanzi kwaye zamkelwa kwintsimbi ore dry beneficiation, kwaye babe namava atyebileyo kuyilo ityala abathengi.Ukuba ufuna intsimbi ekrwada yokusila iprojekthi yentsimbi ekrwada eyomileyo, nceda usitsalele umnxeba ukwazi iinkcukacha zesixhobo.
