Isiphetho:Iphutha le-roller elingamakhulu liyasebenza kahle ekwakheni amafutha amancane angeyona imikhiqizo yezinto zezinto ezisezingeni elikhulu ngaphansi kwe-1250 mesh. Impembelelo yalo enkulu kanye nokuthuthukisa amandla yimpembelelo ebonakalayo.

Isithuthuthu somilingo esikwenketshezi sihambisana kahle nenqubo yokusetshenziswa kwamaminerali angeyona imilo eyi-bulk ngokukhulu, ngaphansi kwe-1250 mesh. Imiphumela yaso yokusebenza ngokukhulu kanye nokuthuthukisa amandla ibalulekile. Ilula ukusebenza, kulula ukuyilondoloza, futhi inethiwekhi elula yokuqhubeka kwezindlela, futhi inezinzuzo zendawo encane, imali encane yokwakha, i-noise encane, kanye nokukhusela indawo kahle. Futhi lapha kukhona izinto ezithinta ukusebenza nokuqhubeka kwesithuthuthu somilingo esikwenketshezi.

Izici zomkhiqizo

Izici zomkhiqizo ikakhulukazi zibhekisela ekugcineni, ubukhulu bezingcezu, uketshezi kanye nokuzwela.

Uqiniso lomkhiqizo oqeqeshwe

Uqiniso lomkhiqizo oqeqeshwayo kuvame ukubonakaliswa ngokusebenzisa i-Mohs hardness (i-range yi-1-10). Ngokuvamile, uma uqiniso lomkhiqizo oqeqeshwayo lungaphezulu, ukukhushulwa kuzoba kubi kakhulu futhi ukusebenza kwemishini ye-vertical roller mill kuzoba kubi kakhulu. Ngakho-ke, uqiniso lomkhiqizo oqeqeshwayo lubalulekile ngqo ekuphumeleleni kwemveliso kanye nexesha lokuqeqeshwa kwengxenye ehlushwa yomshini.

Ubukhulu bezingcezu zomkhiqizo oqeqeshwe

Imishini ye-vertical mill inezidingo ezithile mayelana nobukhulu bezingcezu zomkhiqizo oqeqeshwe.

Uma ukukhuluka kwesidlo sikhulu kakhulu, ukusebenza okuyinhloko kokucisha kuzochithwa, inani lama-esayikili wempahla lizothuthukiswa, futhi amandla okusebenzisa umshini wokucisha azokhuphuka ngokungabonakali.

Uma ubukhulu bembobo buphansi kakhulu, izinto ezimuncu zizokhula ngokungaphezi. Ngenxa yokuthi izinhlanganiso ezincane azinaki kahle futhi ngenxa yemiphumela yomoya oqondiswe ngaphakathi, imikhuba yokushukumiswa yebhedi yempahla iyabonakala, okwenza umshini wokucisha ama-roller oqondile angakwazi ukubamba inani elikhulu lezinto, okuholela ekubeni ilayiya yempahla ingalungile, okubangela ukukhukhuleka.

Ukuhlanzeka kwempahla yokuqala

Ukwahlulela ubukhulu bomswakama wempahla yokuqala kubalulekile kakhulu ekusebenzeni okuhle komshini wokucisha ama-roller oqondile. Uma ubukhulu bomswakama wempahla yokuqala bukhulu kakhulu, impahla ...

Ukulinganisela kokukhuliswa kwezinto ezomile

Ukulinganisela kokukhuliswa kwezinto ezomile kuyinto ehambisana ngqo nokhono lokukhiqiza, ukusetshenziswa kwamandla kanye nokuqhubeka kwesikhathi sokuphila kwe-roller liner ye-vertical roller mill. Uma into inomlinganiso omuhle wokukhuliswa, kulula ukuyicindezela nokuyigaya, futhi kulula ukukhiqiza iphutha elincane kakhulu; ngokuphambene nalokho, into enomlinganiso omubi wokukhuliswa, idinga izinqubo eziningi zokukhuliswa kanye nenhlanganisela enkulu yokucindezela kokukhuliswa, okuyenza ibe yinkulu ukusetshenziswa kwamandla okukhuliswa futhi yikhulise isilinganiso se-roller sleeve kanye ne-liner, okuyenza iphumele ngokushesha.

Uhluhlu lweshwaqeshwaq lwe-vertical roller mill

Uhluhlu lweshwaqeshwaq luyinye yezinto ezibalulekile ezibonisa umthwalo oqeqeshwe ngempahla ngaphakathi kwe-vertical roller mill. Uhluhlu lweshwaqeshwaq lwe-mill luqukethe izigaba ezimbili, eyokuqala isimo sezempilo esikhulu e-wind ring ye-vertical roller mill; esinye isimo sezempilo esenziwe yi-powder concentrator lapho ikhetha khona i-powder. Umlingano walaba bobabili abakhiqizi i-pressure difference ye-mill.

Kunezinto eziningi ezithinta umehluko womoya we-milling, njengokukhuliswa kwempahla, umthamo wokudla, umthamo womoya wesixazululo, umoya wokukhuliswa, kanye nokuhamba kwesixazululo se-powder.

Ukukhula kwesilinganiso sokungabanga okukhulu kubonisa ukuthi inani lezinto zokwakha ezingena emlilweni likhulu kunani lezinto eziqedwe, futhi umthwalo oqeqeshwe emlilweni ukhula. Ngesikhathi esifanayo, umfutho wokuqeqesha ukudla uba mkhulu, futhi inani lokulahla isula likhula. Futhi umkhathi wesithako uqhubeka ukukhula.

Ukwehla kokuhlukana kwengcindezi kukhombisa ukuthi inani lezingxenye ezingenayo kumshini wokugaya liphansi kunenani lemikhiqizo ephelile, futhi umthwalo osiphethiloli osebenza ngaso uyancipha. Ngalesi sikhathi, umjikelezo wokuhambisa okuphakwayo uyancipha, futhi inani lokukhishwa kwe-slash liyancipha. Futhi, isendlalelo sematerial siyancipha kancane kancane.

Umthamo wokuphefumula komshini

Umthamo wokuphefumula ofanele uyimfuneko ebalulekile yokusebenza okunempilo komshini wokugaya ophakeme. Umthamo wokuphefumula ohlelweni lonke lokugaya ugqoka ngqo ekukhiqizeni okuphezulu nasekuphumeleleni kokucacisa.

Uma umthamo wokulinganisela umoya ukhulu, isilinganiso somoya esilimini siyakhula, ikhono lokomelisa nokuthutha izinto liyakhula, ukusabalala kwangaphakathi nangaphandle kwelimi liyancipha, inani lezinto ezingcolile eziseqolo liyakhula, futhi i-output yelimi iyakhula. Uma umthamo womoya ukhulu kakhulu, kungase kubangele ukuthi ukukhuluka kwemveliso kungafaneleki (kuphelelwe ngokungcolile) noma ukulinganiselwa kwezinto ezincanci ezimhlophe kwancipha (inani lama-cycle alinciphile, isikhathi sokuqhuma sifudumele), ukukhuluka kuyancipha, futhi i-mill nayo izogcwala ngenxa ye-layer encane yempahla.

Uma umthamo wokulinganisela umoya uphansi, isilinganiso somoya esibhakabhakeni lomshini wokuqopha siyancipha, amandla okomisa nokuthwala izinto zinciphisa, ukujikeleza kwangaphakathi nangaphandle komshini wokuqopha kuya ngaphezulu, isiqeshana sezinto siqine, ukusetshenziswa kwamandla emashini wokuqopha kuya ngaphezulu, futhi ubukhulu bemveliso buya ngaphansi, kodwa umkhiqizo womshini wokuqopha uyancipha, futhi kungase kubangele ukukhukhumeka noma ukumisa ukukhukhumeka ngoba isiqeshana sezinto siqinile kakhulu.

Umandla oqeqeshwayo wama-roller wokushicilela

Amandla okushicilela komshini wokushicilela oluphezulu weza ekuthwaleni okungapheli kwama-roller wokushicilela kanye nokuqiniswa kwamanzi.

Umthamo wokusebenza wesiqholo sokugaya kufanele ubekwe ngokuhle ngokuvumelana nomthamo wokudlulisa, ubukhulu bemiqolo yempahla, ubukhulu bemveliso kanye nezinye izici. Uma umthamo ungancane kakhulu, ukugaya okusebenzayo akuzuzeki, okuholela ekunciphiselweni komkhiqizo wephunga nekhono lokukhiqiza elincane. Umthamo omkhulu kakhulu ungabangela ukungezwani komqolo wensimbi, okungabangela ukwenzakala okungadingekayo kwesixhumi.

Isilinganiso sokugijima kwesixhumi

Uma isikhungo sinomoya othile, isivinini sesiqholo siphansi futhi ubukhulu bomkhiqizo wokugaya bukhulu; ngokuphambene nalokho, uma umoya ungekho kakhulu, isivinini siphansi futhi ubukhulu bemkhiqizo buphansi.

Ezinye izici

(1) Uphakathi lwesikhwama esigcini

Ubukhulu besikhwama esigcini sibonisa ngqo ukusebenza kahle komkhathi wempahla kanye nokuphumelela kokucisha umshini wamagwebu amakhulu. Uma ubukhulu besikhwama esigcini bukhulu kakhulu, lokhu akusihleli ekukhuleni kwempahla, okuholela ekukhuluweni kweqembu lempahla. Imikhiqizo ethile engenakulinganiswa ayikwazi ukuphuma ngesivinini ngomoya phakathi kokukhulu kweqembu lempahla, okuholela ekucishweni okungaphezu kokuqondene. Uma ubukhulu besikhwama esigcini buphansi kakhulu, isivinini sokulukhuluka kwempahla sizokhuphuka, okuholela ekutheni isizinda sempahla sibe sincane kakhulu, oku-.

(2) Indawo yokukhulula umoya womoya

Ngempela emisebenzini, kuvame ukuboniswa ukuthi inani lensimbi ebuyiswa yi-mill libanzi, kodwa umsebenzi we-vertical roller mill uhlala uqinile. Ngesikhathi sokuqeqeshwa, indawo yokukhulula umoya womoya inganciphisiwe (emathaleni okugcina noma eceleni kwe-wind ring ukulungisa uhlanganiso lwesitayela esiqinile), ukukhuluphaliswa kwesivinini somoya e-air ring, ukwandisa amandla ensimbi, ukunciphisa inani lokulahla isitayela, lokhu kuzothuthukisa ukukhiqiza.

(3) Ukuvama komshini wokugaya nomjikelezo

Ngohlonze lwesipiliyoni, uma umshini wokugaya wamabhuloho ohlangothini oluphakeme uqhubeka isikhathi eside, ikhono lokukhiqiza lizokwehla kuze kube sezingeni elithile, ikakhulukazi ngenxa yokugqoka komshini wokugaya nomjikelezo wokugaya, okubangela izinguquko kumasistimu wokugaya kanye nengcindezi yokugaya endaweni yokugaya.

Inkinga yokugqokwa komshini wokugaya nomjikelezo ithambekele kakhulu ukuveza ukwehla okungazelelwe kwamandla okukhiqiza imikhiqizo ephelele enezidingo eziphezulu zokuphakama. Ngalesi sikhathi, kuyelulekwa ukuthi kulungiswe ubuso bejethi yomshini, kuphinde kufakwe ubuso obusha (ukufaneleka).
