Summary: Umshini wokugcoba wezulu ohlangothini oluphakeme uyafaneleka ukuze kwenziwe izinto ezinkulu zokucubungula amaconsi emaminerali angaphandle kwemishini ephansi engu-1250 mesh. Imiphumela yayo enkulu futhi esindisa amandla ibalulekile....
Umshini wokugaya ohlangothini oluqondile unengqondo yokucubungula ubungako obukhulu bemabula engenaqhaza yezinsimbi ezingaphansi kwe-1250 mesh. Imiphumela yawo enkulu futhi igcina amandla iqine kakhulu. Unokusebenza okulula, ukugcinwa okulula, nokuhleleka kwenqubo okulula futhi unazo izinzuzo zomgama omncane, utshalomali oluphansi ekwakheni kwezobuchwepheshe, umsindo oliphansi, nokuvikelwa kwemvelo okuhle. Futhi nazi ezinye zezici ezithinta ukusebenza komshini wokugaya we-vertical roller mill.
Izici zomkhiqizo
Izimpawu eziyinhloko zezinto ezisetshenziswa zangaphambili zihlala zihlaba umxhwele kumandla azo okubola, usayizi wezinhlayiya, ukumanzisa, nokuthambekela kokuphahlazeka (inkomba yomsebenzi kaBond), njll.
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 usayizi wokudla uluhluli kakhulu, impahla ephuma kuyo izonyaka ngokungabazisiwe. Ngenxa yokungasebenzi kahle kwemilingo yezinhlayiyana ezincane kanye nomthelela womoya wangaphakathi, ibhande lezinto libonisa ukugeleza okucacile, okwenza i-mill yomgodi omisiwe ingakwazi ukubamba izinhlayiyana eziningi, okuholela ebhande lezinto elingeqinelisi kahle kanye nokuzamazama kwemishini.
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 kwendawo yomfutho kukhombisa ukuthi ubukhulu bezinto ezingavuthiwe ezingenayo emshinini buyancipha kunezinto ezigcwalisiwe, futhi umthwalo ojikeleza emshinini uncibilikile. Ngalesi sikhathi, ukuhamba komthwalo wokulayisha kuphansi, futhi inani lokukhishwa kwenqo linciphile. Futhi, isendlalelo sezinto 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 ivolumu yokuphelelisa iyikhulu kakhulu, ijubane lomoya emotweni lonyuka, amandla okomisa nokuhambisa izinto ayandiseka, ukujikeleza ngaphakathi nangaphandle kwemishini kuncishiselwa, inani lamapheshana amakhulu ebusweni bemishini liyandiswa, futhi ukukhiqizwa kwemishini kuyakhula. Uma ivolumu yomoya iphakeme kakhulu, kungaholela ekutheni ikhwalithi yomkhiqizo ingafezi kahle (amapheshana amakhulu) noma kwehlise okuqukethwe kobumba obuphakeme (ngenxa yokuthi ukujikeleza kwezikhathi kungaphansi nokuthuthukiswa kwemfucu yomshini kube ngokushesha), okwenza ikhwalithi yomkhiqizo wehlise. Ngaphezu kwalokho, umshini uzophinde ugrime ngenxa yesikhala sobuso obuncane bemishini.
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).
