Ngenxa yokunqongophala kwamandla kwihlabathi, ukusetyenziswa kwamandla kwinkqubo yokutyumza kuye kwatsala ingqalelo ngakumbi nangakumbi. Ukusukela ekufikeni komatshini wokusila we-high-pressure roller ngasekupheleni kweminyaka yoo-1980, ibisetyenziswa ikakhulu kushishino lwesamente kunye nemigodi yentsimbi engasebenziyo. Ishishini le-samente lixhamle kwesi sixhobo somgangatho ophezulu wokonga amandla kunye nokusetyenziswa kwentsimbi.
Ubungakanani beentsimbi ezichotshoziweyo kwi-metallurgy kunye nemigodi bukhulu, kwaye uninzi lwentsimbi yentsimbi inzima kwaye kunzima ukuyigaya. Okwangoku, iingxaki zokusetyenziswa kwamandla, ukusetyenziswa kwensimbi kunye nokusebenza kakuhle kweebhola zebhola zibalaseleyo, kwaye izinga lokubuyisela amaminerali lichaphazeleka kakhulu kwindlela yokugaya. Ilitye lokusila elinoxinzelelo oluphezulu lisetyenziswa kakhulu kwi-metallurgy nakwishishini lemigodi, kwaye likwinqanaba eliphambili kwihlabathi. Kusisiphumo sokuphonononga okungapheliyo kunye nokusebenza kwabenzi bezixhobo zasekhaya kwiminyaka yakutshanje, kunye nempumelelo yokugqibela.

Umahluko phakathi koxinzelelo oluphezulu lokusila kunye nezixhobo zokutyumza zemveli
Ilitye lokusila elinoxinzelelo oluphezulu lifana kakhulu nefomu kwisityuli sesiqhelo esiphindwe kabini, kodwa kukho iiyantlukwano ezimbini kwisiseko.
Enye yeyokuba i-high-pressure roller mill isebenzisa i-quasi-static crushing, egcina malunga ne-30% yokusetyenziswa kwamandla xa kuthelekiswa nokutyunyuzwa kwempembelelo;
Okwesibini, isebenzise ukutyunyuzwa kwezinto eziphathekayo, okuxutywayo phakathi kwezinto kunye nezixhobo, kunye nokusebenza kakuhle kokutyumza, kunye noxinzelelo lwe-extrusion phakathi kwezinto ezinokulungiswa ngoxinzelelo lwe-roller. Iirola ezimbini zijikeleza ngokuchasene nomnye, enye i-roller esisigxina kwaye enye ingumgama ohlengahlengiswayo. Uxinzelelo phakathi kwee-rollers lunokufikelela ngokubanzi kwi-1500 ukuya kwi-3000 atmospheres, kwaye iimveliso ezichotshoziweyo zinokufikelela kwi-2mm, eqonda "ukutyumza ngakumbi kunye nokugaya okuncinci" kwaye ibe yinto entsha yezixhobo zokutyumza ezithatha indawo yokugaya ngokutyumza. Ngenxa yamandla ayo anamandla, ayigcini nje ukucola izinto eziphathekayo, kodwa iphinda iqhekeze isakhiwo sangaphakathi sezinto eziphathekayo, ngaloo ndlela iphucula kakhulu amandla okugaya.
I-high-high pressure roller mill yenziwe ngesixhobo sokutya kombane, isixhobo sokuthintela izinto, isixhobo sokuqhuba, isixhobo sokulayisha i-hydraulic, isixhobo esixhasayo, izixhobo eziguquguqukayo kunye ne-static roller, njl.
Indawo yokusebenza ye-HUATE HPGM yoxinzelelo oluphezulu lokusila
Inkqubo eqhelekileyo yokuhamba koxinzelelo oluphezulu lokusila kwi-beneficiation
1. Iinkozo ezirhabaxa ezivaliweyo ilitye lokusila elinomsila omanzi inkqubo yokujula
Kwinkqubo yokusebenzisa lo matshini wokucutshungulwa kwe-ore, ukuphoswa komsila omanzi we-coarse-grained evaliweyo yokugaya i-roller roller yinkqubo eqhelekileyo. Lo mfanekiso ulandelayo ubonisa eyona nkqubo iphambili yokuhamba:
Iinkozo ezirhabaxa ezivaliweyo-i-roller yokusila umsila omanzi wokugibisela itshati yenkqubo
Kwisicelo esithile sale nkqubo, ikhekhe le-abrasive lihlolwe ngokukodwa kwisekethe evaliweyo, ukwenzela ukuba ubukhulu be-particle yemveliso eqhutywe yi-high-pressure roller mill inokuhlala ilawulwe ngaphakathi koluhlu olulungele kakhulu ukuhlenga kunye nomsila. , kwaye ekugqibeleni ufezekise injongo yokuphosa kwangaphambili umsila.
1. Inkqubo yokugaya ibhola yenxenye ye-valve-circuit roller mill
Ngokusetyenziswa kwenani elikhulu lezenzo zemveliso kunye novavanyo oluhambelanayo, kufunyaniswe ukuba iimveliso zentsimbi ezifunyenwe yi-high-pressure roller mill azinayo nje isayizi yesuntswana elicolekileyo, kodwa zikwafezekisa ukwanda okukhulu kumxholo we-mineral powder. Phakathi kwazo, umxholo wezinto ezingaphakathi kwe-0.2mm unokufikelela kuma-30% -40%, izinto zolu nqanaba lokulunga zinokuhlangabezana neemfuno zokuhlela i-ore kwiimeko ezininzi, ngoko ngolu hlobo lwemveliso, umsebenzi wokuhlela unokuqhutywa ngokuthe ngqo emva kokuba i-ore ihlelwa. ukuyihlela.
Ngelo xesha, kwinkqubo yokusebenzisa i-high-pressure roller mill ye-ore beneficiation kunye ne-ore yokutyumza imveliso, phantsi kwesenzo se-side material effect, kuya kubakho inxalenye encinci ye-ore ye-ore kunye nobukhulu obugqithisileyo ngaphakathi kwekhekhe le-extrusion. Ukuba le nxalenye isetyenziswe ngokuthe ngqo Ngethuba lokusila okanye ukusebenza kwe-beneficiation, ukuhamba komsebenzi ohambelanayo kuya kuguquguquka kakhulu, okuya kuzisa iqondo elithile leempembelelo ezimbi kwimveliso yoncedo.
Ngoko ke, kwinkqubo yokuveliswa kwe-beneficiation ngezixhobo zoomatshini, ukwenzela ukuba ugweme iingxaki ezinjalo, kuyimfuneko ukwenza ukuhlolwa kwe-circuit-circuit evaliweyo yekhekhe lezinto eziphathekayo emva kokuqhutyelwa kwe-extrusion yi-high-pressure roller mill. Ngale ndlela, ubungakanani bamasuntswana emveliso kwikeyiki bunokulawulwa ngokungqongqo ukuthintela ukuguquguquka kwenkqubo okubangelwa kukungena kwe-ore kunye nobungakanani obukhulu beqhekeza kwibhola yokusila. Kwaye yenze ngokuthe ngqo kwinkqubo yokhetho. Indlela enjalo ayinakufezekisa kuphela ukuncipha okukhulu kwi-ore yokutya kwinkqubo yokugaya ibhola, kodwa iphinde ithintele ngokufanelekileyo ukugaywa kwee-ore ezicolekileyo, ngaloo ndlela iphucula ngokubanzi ukusebenza kunye nomgangatho wokuzuza.
3 Ezinye iindlela zenkqubo yokuqukuqela eqhelekileyo
Ukongeza kwezi zimbini zingasentla iinkqubo ezisetyenziswa ngokuqhelekileyo, kukho iinkqubo ezininzi eziqhelekileyo eziqhelekileyo kwinkqubo yokutyumza kunye nemveliso ye-beneficiation ores nge-roller mill. Enye yi-open-circuit roller mill milling ngendlela ye-particle size size class craft.
Open-circuit roller ibhola lokusila inkqubo flow itshati
Enye yinkqubo yokugaya ibhola ngohlobo lwe-roller grinding edging material circulation. Oku kulandelayo yeyona tshati yenkqubo yayo iphambili:
Itshathi equkuqelayo yenkqubo yokugaya ibhola ngendlela yokujikeleza kwezinto ezisilayo
