Nhanganyaya ye petroleum coke
Mafuta epetroleum coke anogadzirwa kuti aparadzanise mafuta akareruka nemafuta anorema, mafuta anorema anoshanduka kuita chigadzirwa chekupedzisira nekupisa. Kubva pakuonekwa, coke haina chimiro chakasiyana uye saizi yemapundu matema (kana zvidimbu) inopenya nesimbi; zvidimbu zvecoke zvine maburi ane maburi, zvinhu zvikuru icarbon, ine anopfuura 80wt%, zvimwe ihydrogen, oxygen, nitrogen, sarufa uye simbi. Hunhu hwemakemikari hwepetroleum coke hune hunhu hwayo hwepanyama nemakemikari uye hunhu hwemakanika. Kabhoni isingachinjiki inova chikamu chekupisa pachayo, zvinhu zvinoshanduka uye tsvina yemaminerari (sarufa, simbi, mvura, dota, nezvimwewo), zvese izvi zvinoratidza hunhu hwemakemikari hwecoke.
Koka yetsono:ine chimiro chetsono uye magadzirirwo efiber, uye yakawanda inoshandiswa se graphite electrode ine simba guru mukugadzira simbi. Needle coke ine zvinodiwa zvakanyanya zvemhando yepamusoro mu sarufa, dota, volatile uye true density nezvimwewo, saka pane zvinodiwa zvakakosha zvekugadzira ne needle coke uye zvinhu zvakabikwa.
Koka rechipanji:kushandiswa kwakanyanya kwemakemikari, huwandu hushoma hwekusvibiswa, hunonyanya kushandiswa muindasitiri yearuminiyamu neindasitiri yekabhoni.
Koke yakapfurwa kana koke yakazara:chimiro chedenderedzwa chesilinda, dhayamita ye 0.6-30mm, inowanzo gadzirwa ne salfa yakawanda, ine asphalt yakawanda, inogona kushandiswa chete kugadzira magetsi, simende uye mamwe mafuta emumaindasitiri.
Koka yeupfu:Kana ichigadzirwa kuburikidza nekugadzirwa kwemvura, zvidimbu zvacho zvakanaka (dhayamita ye 0.1-0.4mm), high volatile uye thermal expansion coefficient inoita kuti isakwanise kushandiswa zvakananga muma electrodes uye carbon industry.
Kushandiswa kwePetroleum coke
Nzvimbo huru inoshandiswa nepetroleum coke muChina iindasitiri yealuminium yemagetsi, iyo inodarika 65% yehuwandu hwese hwepetroleum coke inoshandiswa. Ichiteverwa necarbon, silicon yemumaindasitiri nedzimwe nzvimbo dzekunyungudutsa. Petroleum coke inonyanya kushandiswa semafuta mu simende, kugadzira magetsi, magirazi nedzimwe nzvimbo, zvichiita kuti ive shoma. Parizvino, kuwanikwa uye kudiwa kwepetroleum coke yemumba kwakafanana. Zvisinei, nekuda kwekutengeswa kwepetroleum coke yakawanda ine sulfur shoma, huwandu hwepetroleum coke yemumba hahuna kukwana, uye petroleum coke yepakati nepakati neyakakwira inofanirwa kutengeswa kunze kwenyika kuti iwedzere. Nekuvakwa kwehuwandu hwakawanda hwema coking units mumakore achangopfuura, kubuda kwepetroleum coke yemumba kuchavandudzwa uye kuwedzerwa.
①Indasitiri yegirazi iindasitiri inoshandisa simba rakawanda. Mari yayo yemafuta inokwana 35% ~ 50% yemutengo wegirazi. Chitofu chegirazi chishandiso chinoshandisa simba rakawanda mukugadzirwa kwegirazi. ② Kana chitofu chegirazi chabatidzwa, hachigone kudzimwa kusvika chitofu chagadziriswazve (makore 3-5). Saka, mafuta anofanira kuwedzerwa nguva dzose kuti ave nechokwadi chekuti tembiricha yechoto inosvika zviuru zvemadhigirii muchoto. Saka, nzvimbo yekupukunyudza gorosi ichave nemichina yekugayira kuti ive nechokwadi chekuti kugadzirwa kunoramba kuripo. ③ Upfu hwepetroleum coke hunoshandiswa muindasitiri yegirazi, uye hutete hunodiwa kuti huve 200 mesh D90. ④ Huremu hwemvura yecoke mbishi hunowanzova 8% - 15%, uye inoda kuomeswa isati yapinda muchigayo. ⑤ Kana hunyoro hwechigadzirwa chapera hwakaderera, zviri nani. Kazhinji, mhedzisiro yemvura inoyerera ye open circuit system iri nani.

Mashoko:
1. Chiyero che "grindable coefficient" che "petroleum coke material" ndicho chinhu chinokanganisa kubuda kwe "grindable coefficient". Kana "grindable coefficient" yakaderera, ndipo panobva "grindable coefficient" shoma;
- Hunyoro hwekutanga hwezvinhu zvakagadzirwa hunowanzova 6%. Kana hunyoro hwezvinhu zvakagadzirwa hwakakura kupfuura 6%, muchina wekuomesa kana chigayo chinogona kugadzirwa nemhepo inopisa kuderedza hunyoro, kuitira kuvandudza kubuda uye kunaka kwezvigadzirwa zvakagadzirwa.

Kuongororwa kwezvakanaka nezvakaipa zvemichina yakasiyana-siyana yekukuya:
Raymond Mill:Nemutengo wakaderera wekudyara, simba rakawanda rinobuda, simba shoma rinoshandiswa, michina yakagadzikana uye mutengo wakaderera wekugadzirisa, chishandiso chakanakira kupwanya petroleum coke;
Chigayo chakamira:mari yakawanda yekudyara, simba rakawanda rinobuda uye kushandiswa kwesimba rakawanda;
Chigayo chemagetsi chinopa simba:mari shoma yekudyara, simba shoma rinobuda, simba rinoshandiswa zvakanyanya, kutadza kushanda kwemidziyo yakawanda uye mari yakawanda yekugadzirisa;
Ongororo yemamodheru ekugaya
Zvakanakira zveHC series grinding mill mu petroleum coke pulverizing:
1. Chigayo cheHC Petroleum Coke Maumbirwo: kumanikidzwa kukuru kwekukuya uye kubuda kwakanyanya, uko kuri 30% yakakwira kupfuura iyo yemuchina wependulum wakajairika. Kubuda kwacho kuri kupfuura 200% yakakwira kupfuura iyo yemuchina weimpact.
2. Kurongeka kwakanyanya: kupfava kwechigadzirwa kunowanzoda 200 mesh (D90), uye kana yakakwira, inosvika 200 mesh (D99).
3. Sisitimu yekugaya ine ruzha rushoma, kudedera kushoma uye kushanda kwakasimba kwekuchengetedza nharaunda.
4. Mwero wekugadzirisa wakaderera, kugadzirisa kuri nyore uye mutengo wakaderera wevashandi.
5. Zvichienderana nezvinodiwa pakuita basa iri, sisitimu yechigayo inogona kupfuudza mhepo inopisa ye300°C kuti iite kugadzirwa kwekuomesa nekukuya (semuenzaniso wezvinhu zvekuvaka zveThree Gorges).
Mashoko: Parizvino, HC1300 neHC1700 grinding mill dzine musika wepamusoro pe90% mukugadzira petroleum coke.

Muridzi wepurojekiti iyi akaongorora kusarudzwa kwemidziyo yemuchina wekukuya wepetroleum coke kakawanda. Nekuenzanisa kwakazara nevagadziri vemichina yekukuya vakawanda, vakatenga michina yakawanda yemuchina wekukuya weGuilin Hongcheng HC1700 nemidziyo yemuchina wekukuya weHC2000 zvakatevedzana, uye vanga vachishamwaridzana uye vachishandira pamwe naGuilin Hongcheng kwemakore mazhinji. Mumakore achangopfuura, mitsetse mitsva yakawanda yekugadzira magirazi yakavakwa. Guilin Hongcheng yakatumira mainjiniya kunzvimbo yemutengi kakawanda zvichienderana nezvinodiwa nemuridzi. Michina yekukuya yeGuilin Hongcheng yave ichishandiswa mumapurojekiti ekukuya kwepetroleum coke efekitori yegirazi mumakore matatu achangopfuura. Mutsetse wekugadzira petroleum coke wakagadzirwa naGuilin Hongcheng une mashandiro akagadzikana, simba rakawanda, simba shoma uye kusvibiswa kweguruva kushoma munzvimbo yekukuya, izvo zvakarumbidzwa zvikuru nevatengi.
