Coke powder ndeye-chigadzirwa chinogadzirwa mukubikira.Nekuda kwekuti zvikamu zvaro zvidiki zvakanyanya, painoungana muchoto chinoputika, kuyerera kwemhepo hakuzove kwakatsetseka, izvo zvinokanganisa kumhanyisa kweiyo mbiru yezvinhu mumoto unoputika, uye haugone kusangana nezvinodiwa zvemetallurgical coke.Nekuti coke poda ine zvimiro zveyakakwira kabhoni, yakagadziridzwa mukati ma voids, uye imwe simba, Chinese vaongorori vesainzi vakaita tsvakiridzo yakadzama uye yakadzama yemashandisirwo ehupfu hwekoki mumakore achangopfuura.HCMilling(Guilin Hongcheng) mugadziri wemetallurgical cokekugaya.Izvi zvinotevera sumo yekushandiswa kwemetallurgical coke grinding mill:

1. Activated carbon from metallurgical coke grinding powder: Activated carbon is carbon material ine yakagadzirwa microporous structure uye yakasimba adsorption kukwanisa.Inoshandiswa zvakanyanya munzvimbo dzakasiyana siyana senge indasitiri yemakemikari, kugadzira chikafu, kuchengetedza kwemauto uye indasitiri yekudzivirira kwezvakatipoteredza.Kuita kweiyo activated kabhoni kunoenderana nenzvimbo yayo chaiyo, micropore vhoriyamu, pore saizi kugovera uye kuumbwa kwemakemikari.Parizvino, iwo makuru ezvigadzirwa zvekugadzira maindasitiri eyakagadzirwa kabhoni munyika yangu huni nemarasha.Mumakore achangopfuura, nekuda kwekushomeka kwesimba kuri kuwedzera uye kusimbisa kwenyika nezvekuchengetedzwa kwezvakatipoteredza, vanhu vari kugara vachitsvaga zvimwe zvigadzirwa zvekugadzira kabhoni yakagadziriswa.Coke poda ndeye-chigadzirwa cheindasitiri yekubika.Iyo ine yakakwira yakagadziriswa kabhoni yemukati, yakaderera kuvhurika uye madota zvemukati, yakakwira simba, uye kuwanikwa kuri nyore kwezvinhu.Icho chinhu chakanakisa chekugadzirira activated kabhoni.Parizvino, activated kabhoni inonyanya kugadzirwa nekurapa coke poda nekuita kwemuviri uye makemikari activation.Iyo yemuviri activation nzira inoda kuti iyo mbishi zvinhu zvinofanirwa kuve kabhoni isati yaitwa, uye yozoitwa pa600 kusvika 1200 ° C.Iyo activator inosanganisira oxidizing magasi akadai CO2 uye mhute yemvura, uye kabhoni maatomu mune oxidizing kabhoni oxide zvinhu zvegasi zvinoshandiswa kupfuura.Activated kabhoni ine mapores akanyatsogadzirwa anoumbwa nemabasa ekuvhura, kuwedzera uye kugadzira ma voids matsva.Chemical activation inoreva kusanganisa mbishi nezvinobatisa (alkali simbi uye alkali simbi hydroxides, inorganic munyu uye mamwe maasidhi) mune imwe chikamu, kuinyudza kweimwe nguva yenguva, uyezve kupedzisa iyo carbonization uye activation nhanho mune imwe nhanho.

2. Biochemical wastewater treatment by metallurgical coke grinding powder: adsorption method inzira inowanzoshandiswa kurapa coking tsvina.Nekuda kwekugadzirwa kwemukati voids yecoke poda uye yakanaka adsorption kuita, vamwe vaongorori muChina vakaita tsvakiridzo pamusoro pecoke poda kurapwa kwekubikira tsvina.Zhang Jinyong anoshandisa coke poda yakashongedzwa neutsi kuti adsorb biochemical tsvina yemvura kubva mukubikira chirimwa.Mushure mekudsorption, iyo kemikari yeokisijeni inodiwa (COD) yemvura yetsvina inodzikiswa kubva pa233mg/L kusvika pa50mg/L, ichisvika kurudzi rwekutanga-class discharge standard.Liu Xian et al.akashandisa coke poda kune yechipiri adsorption kurapwa kwekubikira mvura yetsvina, uye akadzidza akakodzera maitiro mamiriro ecoke poda adsorption yekubikira mvura yetsvina ne static uye ine simba inoenderera kuyedza.Mhedzisiro yetsvagiridzo inoratidza kuti COD ye biochemical wastewater mushure mepamusoro coke poda kurapwa inogona kuderedzwa kusvika isingasviki 100mg/L, uye chromaticity yekubvisa rate inogona kusvika kupfuura 60%, iyo inosangana nemhando yemvura zvinodiwa zvemabhizinesi ekubika.

3. Kugadzira metallurgical coke grinding powder ne additives: iyo nzira coke powder pachayo haina adhesiveness, uye inowanzoshandiswa nekuwedzera binder kwairi kudzvinyirira uye kuumba.Kune marudzi akawanda ehupfu hwehupfu hwekuwedzera, uye kunaka kwekodha yakagadzirwa hakuna kufanana.Liu Baoshan akashandisa musanganiswa wehumate, starch tsvina yakasara, marasha slime, caustic soda uye bentonite sebinder kuti adzidze huwandu hwezvinowedzera, mamiriro ekuumba ehupfu hwecoke, chimiro uye saizi yechidimbu chebhora rekuumba, uye kuomesa. tembiricha, uye Iwo mabhora akagadzirirwa akaedzwa uye akapiswa, uye mhedzisiro yakaratidza kuti mabhora ehupfu hwecoke aive nesimba rakanaka uye kugadzikana kwekupisa, uye aigona kushandiswa kugadzira gasi rakagadzirwa.Zhang Liqi akashandisa iyo coke poda uye tara yakasara inogadzirwa nejenareta gasi kusanganisa uye kuumbwa zvinoenderana neimwe chikamu, uyezve oxidized uye carbonized kugadzira iyo coke yegasification.Zvinhu zvekoki zvasvika pachiyero chegasification coke.Inopa hwaro hwe theoretical hwekugadzirwa kwemaindasitiri.

4. Metallurgical coke grinding powder kuti ibudise metallurgical coke: coke powder inowanzoshandiswa sechinhu chinopera mukugadzirisa.Kuwedzera yakakodzera coke poda mukubika kunogona kuvandudza kunaka kwekoki.Nekuda kwekuwedzera kushomeka kwezviwanikwa zvekubikira marasha muChina, kuitira kuwedzera zviwanikwa zvekubikira uye kuderedza mutengo wekusanganisa marasha, mabhizinesi mazhinji ekubikira akaedza kushandisa coke poda sechinhu chinosanganisa marasha pakubika kuvandudza hupfumi hwecoke. upfu.Mabhizinesi mazhinji muChina akaita tsvakiridzo pakukura kwechikamu uye chikamu checoke poda.Yang Mingping akaita bvunzo yekugadzira maindasitiri pahwaro hweiyo diki coke oven bvunzo.Mhedzisiro yacho inoratidza kuti pasi peyakajairwa pamusoro-kurodha coking process mamiriro, zvinogoneka kuwedzera 3% kusvika 5% yehupfu hwecoke kutsiva marasha akaonda pakubika.Iyo block degree yakawedzera, uye chiyero chekutengesa chakawedzera neinenge 3%.Kuburikidza nekutsvakurudza, Wang Dali et al.akawana kuti kubika necoke powder hakuna maitiro akajeka pamusoro pekunyanya kuratidzwa kwe vitrinite yemarasha akasanganiswa.Zvisinei, kuburikidza nechiyero che microscopic, yakawanikwa kuti coke powder particles yakakura kudarika 0.2mm yakasununguka mu coke, uye zvakanga zvakaoma kubatanidza nezvimwe zvikamu, uye chimiro hachina kuchinja;nepo coke poda idiki pane 0.2mm yaiputirwa zviri nyore necolloid, yaive yakanaka pakugadzira coke.Iyo yakakwana chikamu chehupfu hwecoke ndeye 1.0% -1.7%, iyo yakakwana particle size renji i98% -100% isingasviki 3mm, 78% -80% isingasviki 1mm, uye 40% -50% isingasviki 0.2mm.

Metallurgical coke grinding haiparadzaniswe kubva kune metallurgical coke grinding mill.Semugadziri wemetallurgical coke kugaya chigayo, HCMilling(Guilin Hongcheng) inogadzira.metallurgical coke Raymondchigayo, metallurgical coke ultra-finechigayo, metallurgical coke verticalrollerchigayonemimwe midziyo.Inogona kuburitsa 80-2500 mesh metallurgical coke poda uye inopa rubatsiro rwehunyanzvi rwekushandisa metallurgical coke grinding poda.

Kana iwe uine zvinodiwa zvemetallurgical coke grinding mill, ndapota inzwa wakasununguka kutibata nesu kuti uwane ruzivo rwemidziyo uye upe ruzivo rwekutevera kwatiri:
