Ngenxa yokunqongophala kwamandla ehlabathini, ukusetyenziswa kwamandla kwinkqubo yokutyumza kuye kwatsala ingqalelo engakumbi. Ukusukela oko kwaqala i-roller mill enoxinzelelo oluphezulu ngasekupheleni kweminyaka yoo-1980, ibisetyenziswa kakhulu kwishishini lesamente kunye nemigodi yesinyithi engenasinyithi. Ishishini lesamente liye laxhamla kwesi sixhobo sisebenza kakuhle kakhulu esigcina amandla kunye nokusetyenziswa kwentsimbi.
Ubungakanani beentsimbi ezicoliweyo kwi-metallurgy nakwimigodi bukhulu kakhulu, kwaye uninzi lweentsimbi zesinyithi zinzima kwaye kunzima ukuzicola. Okwangoku, iingxaki zokusetyenziswa kwamandla, ukusetyenziswa kwentsimbi kunye nokusebenza kakuhle kwee-ball mills ziyabonakala kakhulu, kwaye izinga lokubuyiswa kwezimbiwa nalo lichaphazeleka kakhulu yindlela yokucola. I-roller mill enoxinzelelo oluphezulu isetyenziswa kakhulu kwi-metallurgy nakwimizi-mveliso yemigodi, kwaye ikwinqanaba eliphambili kwihlabathi. Sisiphumo sophando olungapheliyo kunye nokusebenza kwabavelisi bezixhobo zasekhaya kwiminyaka yakutshanje, kwaye yimpumelelo yokugqibela.

Umahluko phakathi kwesixhobo sokutshiza esinoxinzelelo oluphezulu kunye nezixhobo zokutyumza zendabuko
I-roller mill enoxinzelelo oluphezulu ifana kakhulu ne-double roller crusher yendabuko, kodwa kukho umahluko emibini ngokwendalo.
Esinye sesokuba i-roller mill enoxinzelelo oluphezulu isebenzisa ukutyumza okungashukumiyo, nto leyo egcina malunga ne-30% yamandla okusetyenziswa xa kuthelekiswa nokutyumza okunempembelelo;
Okwesibini, isebenzisa ukutyumza umaleko wezinto zokwakha, oku kukutyumza okulinganayo phakathi kwezinto zokwakha kunye nezixhobo, ngokusebenza kakuhle kokutyumza, kwaye uxinzelelo lokuphuma phakathi kwezinto lunokulungiswa ngoxinzelelo lwerola. Iirola ezimbini zijikeleza ngokuchaseneyo, enye yirola esisigxina kwaye enye ngumgama ohlengahlengiswayo. Uxinzelelo phakathi kweerola ngokubanzi lunokufikelela kwi-atmospheres ezili-1500 ukuya kuma-3000, kwaye iimveliso ezityumkileyo zinokufikelela kwi-2mm, nto leyo eyenza "ukutyumza okungakumbi kunye nokutyumza okuncinci" kwaye ibe luhlobo olutsha lwezixhobo zokutyumza ezithatha indawo yokutyumza ngokutyumza. Ngenxa yamandla ayo anamandla, ayigcini nje ngokutyumza izinto, kodwa ikwaqhekeza isakhiwo sangaphakathi samasuntswana ezinto zokwakha, ngaloo ndlela iphucula kakhulu amandla okutyumza.
Isixhobo sokugalela esinoxinzelelo oluphezulu senziwe ngesixhobo sokondla ngombane, isixhobo sokuthintela izinto, isixhobo sokuqhuba, isixhobo sokulayisha nge-hydraulic, isixhobo esixhasayo, izixhobo ze-roller eziguqukayo nezingashukumiyo, njl.njl.
Indawo yokusebenza ye-HUATE HPGM roller mill enoxinzelelo oluphezulu
Ukuhamba kwenkqubo eqhelekileyo yesixhobo sokugalela esinoxinzelelo oluphezulu ekuxhamleni
1. Inkqubo yokuphosa umsila omanzi ocoliweyo we-roller mill
Kwinkqubo yokusebenzisa lo matshini ekucubunguleni i-ore, ukuphoswa komsila omanzi kwe-coarse-grained closed-circuit roller milling yinkqubo eqhelekileyo. Lo mfanekiso ulandelayo ubonisa ukuhamba kwenkqubo ephambili:
Itshati yenkqubo yokuphoswa komsila omanzi oneengqolowa eziqinileyo
Kwindlela ethile esetyenziswa ngayo le nkqubo, ikeyiki erhabaxa ijongwa kakhulu ngesekethe evaliweyo, ukuze ubungakanani besuntswana yemveliso ecutshungulwa yiroller mill enoxinzelelo oluphezulu buhlale bulawulwa ngaphakathi koluhlu olufanelekileyo kakhulu lokuhlela nokuthunga, kwaye ekugqibeleni kufezekiswe injongo yokuphosa umsila kwangaphambili.
1. Inkqubo yokusila ibhola engaphelelanga yesixhobo sokusila esijikelezayo esivaliweyo
Ngeendlela ezininzi zokuvelisa kunye novavanyo oluhambelanayo, kufunyaniswe ukuba iimveliso ze-ore ezifunyenwe yi-roller mill enoxinzelelo oluphezulu azinazo nje kuphela ubungakanani be-particle ecolekileyo, kodwa zikwafumana ukwanda okukhulu kumxholo we-mineral powder. Phakathi kwazo, umxholo wezinto ezingaphakathi kwe-0.2mm unokufikelela kwi-30%-40%, izinto ezikule nqanaba lobunzima zinokuhlangabezana neemfuno zokuhlelwa kwe-ore kwiimeko ezininzi, ngoko ke kolu hlobo lwemveliso, umsebenzi wokuhlelwa unokwenziwa ngqo emva kokuhlela.
Kwangaxeshanye, kwinkqubo yokusebenzisa i-roller mill enoxinzelelo oluphezulu ekuveliseni i-ore kunye nemveliso yokutyumza i-ore, phantsi kwesenzo sempembelelo yezinto ezisecaleni, kuya kubakho inxalenye encinci yamasuntswana e-ore anobukhulu obukhulu be-particle ngaphakathi kwekhekhe lokuphuma. Ukuba le nxalenye isetyenziswa ngokuthe ngqo Ngexesha lokusebenza kokusila okanye ukutyumza, ukuhamba komsebenzi ohambelanayo kuya kutshintsha kakhulu, okuya kuzisa inqanaba elithile lempembelelo embi kwimveliso yokutyumza.
Ke ngoko, kwinkqubo yokuvelisa i-ore ngezixhobo zoomatshini, ukuze kuthintelwe iingxaki ezinjalo, kuyimfuneko ukwenza uvavanyo lokujikeleza kwe-closed-circuit yekhekhe yezinto emva kokucutshungulwa kwe-extrusion yi-roller mill enoxinzelelo oluphezulu. Ngale ndlela, ubungakanani be-particle yemveliso kwikhekhe bunokulawulwa ngokungqongqo ukuthintela ukuguquguquka kwenkqubo okubangelwa kukungena kwe-ore enobukhulu be-particle obukhulu kakhulu ekusebenzeni kwe-ball milling. Kwaye iyenze ngqo kwinkqubo yokukhetha. Le ndlela ayinakufezekisa kuphela ukuncipha okukhulu kwinani le-ore kwinkqubo ye-ball milling, kodwa ikwathintela ngokufanelekileyo ukugaywa kwe-ore ezicoliweyo, ngaloo ndlela iphucula ngokupheleleyo ukusebenza kakuhle kunye nomgangatho we-proficiation.
3 Ezinye iindlela zenkqubo eqhelekileyo yokuhamba kwenkqubo
Ukongeza kwezi nkqubo zimbini zingentla zisetyenziswa kakhulu, kukho ezinye iinkqubo eziqhelekileyo eziqhelekileyo kwinkqubo yokutyumza nokuvelisa iintsimbi zokuhluza ezenziwe ziiroller mills. Enye kukugaya ibhola yeroller mill evulekileyo ngendlela yobugcisa beklasi yobukhulu obupheleleyo.
