I-vertical roller mill iyithuluzi elibalulekile nelibalulekile embonini yokucubungula i-powder, esetshenziswa kabanzi ezimbonini ezahlukene zomnotho wezwe. Isibonelo, imboni yezimayini zensimbi. I-iron ore igaywa nge-iron ore vertical roller mill, bese ihlolwa ngemishini yokuzuza ngaphambi kokungena enkambisweni yokuncibilikisa, okungathuthukisa ikhwalithi yensimbi encibilikisiwe futhi kunciphise ukusetshenziswa kwamandla kuyo yonke inqubo yokuncibilikisa. I-HCMilling (Guilin Hongcheng), njengomkhiqizi we-iron ore grinding mill, yethula ukusetshenziswa okulandelayo kwe insimbi eningiumshini wokugaya oqondile ekusetshenzisweni kwe-iron ore dry.

Njengamanje, inqubo yokuhlanza ngamanzi isetshenziswa kakhulu ukuthuthukisa izinga le-ore. Izinyathelo zenqubo zimi kanje: ngemva kokuba i-ore eluhlaza ichotshoziwe, i-slurry efanele ukuhluzwa ilungiswa ngokugaya ohlelweni lokugaya ibhola oluvundlile. I-slurry ihlukaniswa ohlelweni lokuhlanza amanzi ukuze kwakheke i-concentrate powder enezinga eliphezulu lensimbi kanye ne-tailings enezinga eliphansi lensimbi. Inqubo yokugaya nokufaka i-slurry idinga ukudla izinsiza eziningi zamanzi, ikakhulukazi ezindaweni zemayini ezingenazo imithombo yamanzi, ngakho-ke ukongiwa kwamanzi kanye nokungenisa amanzi kuba yizinkinga ezinzima. Ukuze kuncishiswe izinkinga ezishiwo ngenhla, ukugaya nokuhlanza amanzi ngaphansi kwesimo sokungabi namanzi noma ukusetshenziswa kwamanzi okuncane sekuwumgomo ophishekelwa abantu. Kodwa-ke, njengamanje, yonke inqubo yokugaya nokuhlanza amanzi okomile ayisetshenziswa kakhulu ekusebenzeni. Ihlose inkinga yokusetshenziswa kwamanzi amaningi enkambisweni yokugaya nokuhlanza amanzi ekhona, umshini wokugaya oqondile we-iron ore uhlinzeka ngenqubo yokuhlanza amanzi okomile: i-iron ore echotshoziwe igaywa ibe yingxube yezinhlayiya ze-ore kanye ne-ore powder yi-dry insimbi eningiumshini wokugaya oqondile; Impuphu ye-ore kanye nezinhlayiya zihlukaniswa nge-multistage lifting air separator; Izinhlayiya ze-ore zihlukaniswa nge-multistage magnetic roller concentrator ukuze zihlukaniswe zibe yi-concentrate yezinga eliphezulu, i-ore ephakathi yezinga elijwayelekile kanye ne-low-grade tailings. I-ore ephakathi ibe isibuyiselwa emgodini wensimbi ojikelezayo oqondile ukuze igaywe kabusha.

Njengamanje, umshini wokugaya ovame ukusetshenziswa yizinkampani zokucubungula i-iron ore emanzi ngokuvamile uwumshini wokugaya ojwayelekile, ongagcini nje ngokudla izinsiza zamanzi, kodwa futhi udla ugesi omningi. Umshini wokugaya oqondile we-iron ore osetshenziswa ekuhlanzeni i-iron ore eyomile uwuhlobo olusha lomshini wokugaya osebenza kahle kakhulu ekukhiqizeni kanye nokusebenza okuphephile nokuthembekile. Isakhiwo sawo esiyinhloko sakhiwe yi-main motor, i-main reducer, i-grinding disc, i-grinding roller kanye ne-tensioning and pressurizing device, uhlaka, i-separator, amasango amathathu, idivayisi yokufaka nokulungisa, idivayisi yokushayela eyisizayo kanye nepayipi lomoya lokuvala. Uma kuqhathaniswa nomshini wokugaya omanzi wokwenza i-wet beneficiation,insimbi eningiumshini wokugaya oqondileinezinzuzo ezilandelayo:

(1) I-roller mill eqondile yensimbi inamandla okukhiqiza aphezulu futhi inciphisa kakhulu ukusetshenziswa kwamandla okugaya. Uma kuqhathaniswa ne-tube mill, ukusetshenziswa kwamandla kwe-roller mill eqondile kungu-50% ~ 60% kuphela kwalokho kwe-ball mill, okuhlukahluka ngokuqukethwe komswakama wezinto zokusetshenziswa. Uma okuqukethwe komswakama kuphakeme, kulapho konga khona imali. Ngokuvamile, ukusetshenziswa kwamandla kwe-roller mill eqondile yokugaya usimende kungu-20 ~ 25 kW · h/t, kanti okwe-tube mill yendabuko kungu-40 ~ 45 kW · h/t, okunomphumela osobala wokonga amandla.

(2) Amandla okomisa aqinile. Umoya oshisayo omningi ungasetshenziswa, ikakhulukazi ukusetshenziswa kabusha kwegesi elahliwe enokushisa okuphansi ekugcineni kwe-PC kiln noma i-PH kiln.

(3) Uhlelo lulula, luhlanganisa ukuchoboza, ukomisa, ukukhethwa kwempuphu kanye nezinye izinqubo, okwenza inqubo ibe lula. I-roller mill eqondile isetshenziswa njengohlelo lokugaya, futhi umshini wokomisa kanye nowokugxilisa impuphu ohlelweni lokugaya ungasuswa. Akugcini nje ngokunciphisa ukutshalwa kwezimali kwemishini, kodwa futhi kwenza inqubo ibe lula, okwenza uhlelo lonke luphephe futhi luthembeke kakhudlwana.

(4) Ukulawula okulula. Isikhathi sokugcina izinto ezisetshenziswa emshinini wokugaya singamaminithi angu-2-3 kuphela, kanti leso esisemshinini wokugaya singamaminithi angu-15-20. Ngakho-ke, inqubo yokusebenza kulula ukuyishintsha, ukwakheka kwamakhemikhali kungalungiswa ngokushesha, futhi ukusatshalaliswa kosayizi wezinhlayiya zomkhiqizo kuyafana.

(5) Usayizi wezinhlayiya zezinto zokuphakelayo mkhulu, futhi usayizi wezinhlayiya zokuphakelayo ungafinyelela ku-4% ~ 5% wobubanzi bomqulu.

(6) Umsindo ophansi. Njengoba i-roller ye-roller mill eqondile ingaxhumani ngqo ne-grinding disc, kuyilapho i-tube mill isebenzisa ibhola lokugaya ukuxhumana ngqo nezinto, akukho msindo wokushaya kwensimbi, futhi umsindo uphansi ngo-10 dB kunowe-tube mill.

(7) Akukho ukuvuza komoya okuningi. I-roller mill eqondile isebenza kahle ekuvaleni kanye nesethi "yohlelo lokuvala umoya", oluthuthuke kakhulu futhi oluthembekile kune-mechanical seal yendabuko, ngakho-ke lungcono kakhulu ekusetshenzisweni kwegesi elahliwe enokushisa okuphansi.

(8) Izinga lokusebenza eliphezulu. I-roller mill eqondile inezinzuzo zokusebenza kahle kakhulu kanye nokuguga okuphansi. Uma ugaya ukudla okuluhlaza, ukusetshenziswa kwezingxenye ezigugile ngokuvamile kungu-6-8 g/t, futhi impilo yesevisi ye-roll sleeve ne-lining plate ingafinyelela amahora angaphezu kuka-8000. Lapho i-tube mill yendabuko isebenza, ibhola lokugaya kanye ne-abrasive kuthintana ngqo. Ibhola lokugaya kanye ne-lining plate kugqokwa ngokushesha, izesekeli zishintshwa njalo, futhi izinga lokusebenza kwemishini liphansi. Izinga lokusebenza kwe-roller mill eqondile lifinyelela ngaphezu kuka-90%.

I-HCMilling (Guilin Hongcheng) ingumkhiqizi wemishini yokugaya eqondile yensimbi.I-HLM series iron oreumshini wokugaya oqondile zisetshenziswe kabanzi futhi zaziwa ekukhiqizeni i-iron ore dry, futhi zinolwazi oluningi ekuklameni amakesi amakhasimende. Uma udinga umshini wokugaya i-iron ore wephrojekthi yokukhiqiza i-iron ore dry, sicela usishayele ucingo ukuze uthole imininingwane yemishini.

Uma unezidingo ezifanele, sicela ukhululeke ukuxhumana nathi ukuthola imininingwane ngemishini futhi usinikeze ulwazi olulandelayo:
