Coke powder ke sehlahisoa se hlahisoang nakong ea ho pheha.Hobane likaroloana tsa eona li nyenyane haholo, ha li bokella ka sebōping sa ho phatloha, ho phalla ha moea ho ke ke ha e-ba bonolo, e leng se tla ama ts'ebetso e tloaelehileng ea mohala oa thepa ka sebōping sa mollo, 'me e ke ke ea finyella litlhoko tsa coke ea metallurgical.Hobane phofo ea coke e na le thepa ea lik'habone tse phahameng, tse entsoeng ka hare ho li-voids, le matla a itseng, bafuputsi ba saense ba Machaena ba entse lipatlisiso tse pharaletseng le tse tebileng mabapi le mokhoa oa ho sebelisa phofo ea coke lilemong tsa morao tjena.HCMilling(Guilin Hongcheng) ke moetsi oametallurgical cokeleloala la ho sila.Se latelang ke selelekela sa tšebeliso ea leloala la metallurgical coke:

1. Acated carbon ho tloha metallurgical coke grinding powder: Activated carbon ke thepa ea carbon e nang le sebopeho sa microporous se tsoetseng pele le matla a matla a adsorption.E sebelisoa haholo libakeng tse fapaneng tse kang indasteri ea lik'hemik'hale, ts'ebetso ea lijo, ts'ireletso ea sesole le indasteri ea ts'ireletso ea tikoloho.Ts'ebetso ea khabone e kentsoeng e amana le sebaka sa eona se ikhethileng, bophahamo ba micropore, kabo ea boholo ba pore le sebopeho sa lik'hemik'hale.Hajoale, lisebelisoa tse ka sehloohong tse tala bakeng sa ho lokisoa ha k'habone e kentsoeng naheng ea heso ke lehong le mashala.Lilemong tsa morao tjena, ka lebaka la khaello e ntseng e eketseha ea matla le ho hatisa ha naha ho sireletsa tikoloho, batho ba lula ba batla lisebelisoa tse ling tse tala bakeng sa ho lokisa carbon activated.Coke powder ke sehlahisoa sa indasteri ea ho pheha.E na le khabone e tsitsitseng e phahameng, boemo bo tlase bo sa tsitsang le molora, matla a phahameng, le ho fumaneha habonolo ha lisebelisoa tse tala.Ke lisebelisoa tse ntle haholo tsa ho lokisa carbon activated.Hona joale, carbon activated e hlahisoa haholo-holo ka ho phekola phofo ea coke ka ts'ebetso ea 'mele le ts'ebetso ea lik'hemik'hale.Mokhoa oa ho kenya tšebetsong 'mele o hloka hore lisebelisoa tse tala li kenngoe ka khabone pele li sebetsa, ebe li kengoa tšebetsong ho 600 ho isa ho 1200 ° C.The activator e kenyelletsa likhase tse oxidizing joalo ka CO2 le mouoane oa metsi, 'me liathomo tsa k'habone tse ka har'a oxidizing carbon oxide material ea khase li sebelisoa ho feta.Khabone e kentsoeng e nang le li-pores tse ntlafalitsoeng hantle e thehoa ke mesebetsi ea ho bula, ho holisa le ho theha likheo tse ncha.Tšebeliso ea lik'hemik'hale e bua ka ho kopanya lisebelisoa tse tala le li-activators (tšepe ea alkali le li-hydroxide tsa tšepe tsa alkali, matsoai a sa tloaelehang le li-acids tse ling) ka tekanyo e itseng, ho li qoelisa ka nako e itseng, ebe li phethahatsa mehato ea carbonization le ts'ebetso ka mohato o le mong.

2. Phekolo ea metsi a litšila a biochemical ka metallurgical coke grinding powder: mokhoa oa adsorption ke mokhoa o tloaelehileng o sebelisoang ho phekola metsi a litšila a coking.Ka lebaka la li-voids tse entsoeng ka hare tsa coke powder le ts'ebetso e ntle ea adsorption, bafuputsi ba bang ba Chaena ba entse lipatlisiso mabapi le phekolo ea phofo ea coke ea metsi a litšila.Zhang Jinyong o sebelisa phofo ea coke e kentsoeng ke mouoane ho khahlisa metsi a litšila a biochemical a tsoang semeleng sa coking.Ka mor'a adsorption, tlhokeho ea oksijene ea lik'hemik'hale (COD) ea metsi a litšila e fokotsehile ho tloha ho 233mg/L ho ea ho 50mg/L, ho fihlela tekanyetso ea naha ea boemo ba pele ba ho ntša metsi.Liu Xian et al.e sebelisitse phofo ea coke bakeng sa phekolo ea bobeli ea adsorption ea metsi a litšila, 'me a ithuta maemo a loketseng a ts'ebetso bakeng sa adsorption ea phofo ea coke ea metsi a litšila ka liteko tse tsitsitseng le tse matla tse tsoelang pele.Liphetho tsa lipatlisiso li bontša hore COD ea metsi a litšila a biochemical ka mor'a hore phekolo e tsoetseng pele ea phofo ea coke e fokotsehe ho feta 100mg / L, 'me tekanyo ea ho tlosa chromaticity e ka fihla ho feta 60%, e finyellang litlhoko tsa boleng ba metsi tsa likhoebo tsa ho pheha.

3. Ho thehoa ha metallurgical coke ho sila phofo e nang le li-additives: mokhoa oa coke phofo ka boeona ha o na sekhomaretsi, 'me hangata o sebelisoa ka ho eketsa binder ho eona bakeng sa ho hatella le ho theha.Ho na le mefuta e mengata ea li-additives tsa coke powder, 'me boleng ba coke bo hlahisoang ha bo tšoane.Liu Baoshan o sebelisitse motsoako o kopanyang oa humate, masala a litšila tsa starch, slime ea mashala, caustic soda le bentonite e le setlamo ho ithuta palo ea li-additives, maemo a ho bōptjoa ha phofo ea coke, sebōpeho le boholo ba karoloana ea bolo e bopang, le ho omisa. mocheso, le The Libolo tse lokiselitsoeng li ile tsa lekoa 'me tsa lelekoa,' me liphello li bontša hore libolo tsa phofo ea coke li na le matla a matle le botsitso ba mocheso, 'me li ka sebelisoa ho hlahisa khase ka maiketsetso.Zhang Liqi o ile a sebelisa phofo ea coke le masala a tar a hlahisoang ke jenereithara ea khase ho kopanya le ho bōpa ho ea ka karolo e itseng, ebe oxidized le carbonized ho etsa coke bakeng sa gasification.Thepa ea coke e fihlile boemong ba coke ea gasification.E fana ka motheo oa theory bakeng sa tlhahiso ea indasteri.

4. Metallurgical coke grinding phofo ho hlahisa coke metallurgical: phofo ea coke e atisa ho sebelisoa e le moemeli o fokolang nakong ea ho pheha.Ho eketsa phofo ea coke e loketseng nakong ea ho pheha ho ka ntlafatsa boleng ba coke.Ka lebaka la khaello e ntseng e eketseha ea lisebelisoa tsa mashala Chaena, e le ho atolosa lisebelisoa tsa mashala a ho pheha le ho fokotsa litšenyehelo tsa ho kopanya mashala, likhoebo tse ngata tsa ho pheha li lekile ho sebelisa phofo ea coke e le karolo ea motsoako oa mashala bakeng sa ho pheha ho ntlafatsa melemo ea moruo ea coke. phofo.Likhoebo tse ngata tsa Chaena li entse lipatlisiso ka boholo ba likaroloana le karolo ea phofo ea coke.Yang Mingping o ile a etsa tlhahlobo ea tlhahiso ea indasteri motheong oa tlhahlobo e nyane ea ontong ea coke.Liphello li bontša hore tlas'a maemo a tloaelehileng a ho kenya li-coking, hoa khoneha ho eketsa 3% ho 5% ea phofo ea coke ho nka sebaka sa mashala a mafura bakeng sa ho pheha.Sekhahla sa block se ile sa eketseha, 'me sekhahla sa thekiso se ile sa eketseha ka hoo e ka bang 3%.Ka lipatlisiso, Wang Dali et al.o fumane hore ho pheha ka phofo ea coke ha ho na phello e hlakileng ho bonahatsa boholo ba vitrinite ea mashala a kopantsoeng.Leha ho le joalo, ka tekanyo ea microscopic, ho ile ha fumanoa hore likaroloana tsa phofo ea coke tse kholo ho feta 0.2mm li ne li ikemetse ka har'a coke, 'me ho ne ho le thata ho kopanya le likarolo tse ling,' me sebōpeho ha sea fetoha;ha phofo ea coke e nyane ho feta 0.2mm e ne e phuthetsoe habonolo ke colloid, e neng e loketse ho etsoa ha coke.Karolo e nepahetseng ea phofo ea coke ke 1.0% -1.7%, tekanyo e nepahetseng ea boholo ba likaroloana ke 98% -100% ka tlase ho 3mm, 78% -80% ka tlase ho 1mm, le 40% -50% ka tlase ho 0.2mm.

Metallurgical coke sila ke ntho e ke keng ea arohanngoa le leloala la metallurgical coke grinding.E le moetsi oa metallurgical coke sila leloala, HCMilling(Guilin Hongcheng) hlahisa.metallurgical coke Raymondleloala, metallurgical coke e ntle hahololeloala, metallurgical coke e otlolohilengrolaraleloalale lisebelisoa tse ling.E ka hlahisa phofo ea 80-2500 mesh metallurgical coke le ho fana ka tšehetso ea tekheniki bakeng sa tšebeliso ea phofo ea metallurgical coke grinding.
