Izinto ezithinta usayizi wezinhlayiyana zomshini wokugaywa we-high-pressure roller

Izigayo ze-high-pressure roller zisetshenziswa kakhulu ezimayini ezinkulu kanye nezimboni ezichotshozwayo ezihambisanayo. Zinezici zomthamo omkhulu wokukhiqiza, imbudumbudu yokukhishwa okuhle, ukusetshenziswa kwamandla okuphansi kweyunithi kanye nokusetshenziswa kwensimbi okuphansi. Ngemva kweminyaka yocwaningo, kutholakala ukuthi usayizi wezinhlayiyana ze-high-pressure roller mill akuhambisani kuphela nemvelo ye-ore yasekuqaleni, kodwa futhi ihlobene nokusebenza nezinye izici.

Okokuqala, i-roll surface pressure

Kwatholakala ngokuhlolwa ukuthi ngokukhuphula ingcindezi endaweni yokugaya ye-high-pressure roller mill, usayizi wezinhlayiya eziphumayo zezinto ezimaphakathi nezinhlangothi zaba ngcono, ukusabalalisa usayizi wezinhlayiyana zezinto ezimaphakathi kwakugxilwe kakhulu, futhi inhlayiya. ukusatshalaliswa kosayizi wezinto eziseceleni kwakufana kakhulu. Umthelela wokuchotshozwa wezigayo ze-high-pressure roller ezintweni ngokuyinhloko uncike ekucindezelweni kwezinto eziseduze nebanga elincane phakathi kwama-roller amabili. Ngokuvamile, ingcindezi ethile (isilinganiso sokucindezela okuphelele okuhlinzekwa yisistimu ye-hydraulic kuya kububanzi nobubanzi be-rollers) isetshenziswa njengesilinganiso sokucindezela kokusebenza. Imingcele yomsebenzi.

Ngokunyuka kwengcindezi endaweni yomqulu, i-coefficient efanayo yezinto ezimaphakathi iyakhula, ukusatshalaliswa kosayizi wezinhlayiyana kugxilwe kakhulu, isilinganiso sokuchotshozwa siyakhula, usayizi wezinhlayiyana eziphumayo ziba ngcono, futhi ingxenye ecolekile yezinto ezimaphakathi. ngemva kokuchotshozwa kulandisa iningi; Njengoba ingcindezi ikhula, i-coefficient efanayo yezinto ezinqenqemeni iyancipha, ukusatshalaliswa kosayizi wezinhlayiyana kuba banzi, isilinganiso sokuchotshozwa siyakhula, futhi usayizi wezinhlayiyana zokukhipha uyancipha. I-high-pressure roller mill edge material iseduze nomkhiqizo ochotshoziwe ovamile.

Ingxenye ecolekile yemidiya echotshoziwe iningi. Lokhu kungenxa yokuthi "umphumela wosayizi" wezinhlayiya zamaminerali (amandla omshini wezinhlayiya ze-ore akhuphuka kakhulu ngokuncipha kosayizi we-ore) ngesikhathi senqubo yokucwenga. Izinto ezihlanjululwe kahle zinzima kakhulu ukugoqa kunezinsimbi eziqinile ngaphansi kwengcindezi ye-roll surface, ukuze izinto ezihlanjululwe kahle ziphendule iningi.

I-high-pressure roller mill side material iseduze nomkhiqizo ochotshoziwe ovamile, obangelwa "umphumela onqenqemeni" we-roller yokucindezela phakathi nenqubo yokuchoboza. Ukucindezela okungaphansi kwe-roller ebusweni kuma-baffles emikhawulweni yomibili ye-roller yokucindezela kanye nonqenqema lwe-roller yokucindezela kwenza izinto zishelele kalula ngokuhlobene nomphetho we-roller yokucindezela, kunciphisa umphumela wokuchoboza wesendlalelo sezinto, ukuze indlela yokuchoboza. wezinto ezisemaphethelweni we-roller useduze nendlela evamile yokuchoboza.

Okwesibili, ijubane le-roller surface

Ngaphansi kwengcindezi efanayo ye-roll surface, lapho ijubane le-roll surface lenyuka lifinyelela inani elithile, i-coefficient yokufana yezinto ezimaphakathi iyakhula, ukusatshalaliswa kosayizi wezinhlayiyana kugxilwe kakhulu, isilinganiso sokuchotshozwa sikhuphuka, futhi usayizi wezinhlayiyana zomkhiqizo uba ngcono, kodwa kuthinta i-coefficient efanayo yezinto eziseceleni futhi Ukuguqulwa kwesilinganiso sokuchotshozwa akubonakali; kodwa lapho ijubane le-roller surface likhuphuka ngokuqhubekayo, ukuguqulwa kwesilinganiso sokuchotshozwa kwezinto eziphakathi akusabonakali.

Isivinini esifanelekile sihlobene nezici ezingaphezulu zomqulu, ubulukhuni bento, kanye nosayizi wesiphakeli sensimbi. Ijubane le-roll surface lithinta ngokuqondile umthamo wokuchoboza kanye nezinga lokuguga endaweni ye-roll, futhi kuzothinta izici zesayizi yezinhlayiyana zomkhiqizo. Ukwandisa isivinini se-roller surface kunomphumela omncane ezicini zesayizi yezinhlayiyana zokukhishwa, futhi ukusetshenziswa kwamandla kweyunithi ye-high-pressure roller mill akushintshile kakhulu, kodwa amandla ayo okucubungula athuthukiswe kakhulu. Kodwa-ke, isivinini esiphezulu se-roller surface sizogqoka i-roller surface kanye nama-bearings, okuzothinta impilo yesevisi yemishini.

Okwesithathu, okuqukethwe umswakama

Insimbi eluhlaza ekhiqizwa esizeni ivamise ukuba namanzi athile. Ngokushintsha kokuqukethwe kwamanzi e-ore, amandla kanye ne-viscosity ye-ore ishintsha, okuzothinta izici ezibonakalayo zenqubo yokuchoboza. Lapho ukucindezela kwe-roller surface kanye nesivinini se-roller surface kuhlala njalo, okuqukethwe komswakama we-ore kuyanda, i-coefficient yokufana kwezinto ezimaphakathi iyakhula, futhi ukusatshalaliswa kosayizi wezinhlayiyana kugxile kakhulu; isilinganiso sokuchotshozwa kwezinto eziseceleni siyakhula, kodwa ukwanda akubonakali, futhi ukusatshalaliswa kosayizi wezinhlayiyana kuba banzi.

Kungabonakala ukuthi ukwanda komswakama wempahla eluhlaza kunomphumela omncane kusayizi wezinhlayiyana zokukhishwa. Ngesikhathi esifanayo, umswakama wezinto ezibonakalayo endaweni yokukhiqiza ye-high-pressure roller mill ngokuvamile uphakathi kuka-3% no-5%, ngakho-ke ekukhiqizeni okuvamile, ngeke kuthinte Ukukhishwa kunomthelela omkhulu.

Kafushane, empeleni, izinto eziningi ezithinta usayizi wezinhlayiyana eziphumayo zomshini wokugaywa wokucindezela okuphezulu zikumodi yokusebenza. Lapho kukhethwa ukucindezela kwendawo efanele yerola kanye nesivinini sobuso berola, usayizi wezinhlayiyana eziphumayo zomshini wokugaya umfutho ophezulu ungafinyelela ekukhiqizeni. Isidingo, esidinga ukuthi abasebenzi abakhiqizayo babe nezinga elithile lokujwayela izinto zensimbi eluhlaza kanye nemishini yokusebenza, ngakho-ke kubaqhubi bangempela, ubungcweti babo buyisici esibalulekile esithinta usayizi wezinhlayiyana zomshini wokugaywa we-high-pressure roller.
