Isingeniso kumalahle
Amalahle uhlobo lwe-carbonisized fossil mineral. Ihlelwe yikhabhoni, i-hydrogen, umoya-mpilo, i-nitrogen nezinye izinto, iningi elisetshenziswe njengophethiloli ngomuntu. Njengamanje, amalahle anezikhathi ezingama-63 zevolumu egciniwe kune-petroleum. Amalahle abizwa ngegolide elimnyama kanye nokudla kwemboni, amandla amakhulu kusukela ngekhulu le-18. Ngesikhathi sokuguqulwa kwezimboni, kanye nokusungulwa kanye nokusetshenziswa kwe-Steam Injini, amalahle asetshenziswa kabanzi njengophethiloli wezimboni futhi aletha amabutho amakhulu akhiqizwayo emphakathini.
Ukusetshenziswa kwamalahle
Amalahle aseChina ahlukaniswe izigaba eziyishumi. Ngokuvamile, amalahle ancishisiwe, amalahle anamafutha, amalahle anamafutha, amalahle abuthakathaka, awohlokayo futhi amalangabi amalangabi abizwa ngokuthi amalahle abekiwe; ILean Coal ibizwa nge-semi anthracite; Uma okuqukethwe okuguquguqukayo kukhulu kune-40%, ibizwa ngokuthi yi-lignite.

I-Lignite:
Iningi elikhulu, nsundu emnyama, umnyama luster, ukuthungwa okuvulekile; Iqukethe cishe ama-40% aguqukayo, iphuzu lokulahla okuphansi futhi kulula ukubamba umlilo. Isetshenziswa ngokuvamile embonini ye-sosication, embonini ye-liquefaction, i-boiler yamandla, njll.
I-Bituminous Coal:
Ngokuvamile i-granular, encane ne-powdery, emnyama kakhulu futhi icwebezele, ngokuthungwa okuhle, okuqukethe izinto ezingaphezu kuka-30% eziguqukayo, iphuzu lokulahla eliphansi futhi kulula ukusula; Amalahle amaningi anciphise anamathele futhi kulula ukuslayida ngesikhathi sokuvutha. Isetshenziswa ekuhlekeni, ukuhlanganiswa kwamalahle, i-boiler yamandla nemboni yenkundla.
I-Anthracite:
Kunezinhlobo ezimbili zempuphu nezicucu ezincane, ezimnyama, zensimbi futhi ezicwebezelayo. Ukungcola okuncane, ukuthungwa okuhlangene, okuqukethwe okuphezulu kwekhabhoni, kuze kube ngaphezu kwama-80%; Okuqukethwe okuguquguqukayo kuphansi, ngaphansi kwe-10%, iphuzu lokulahla liphezulu, futhi akulula ukubamba umlilo. Inani elifanele lamalahle nenhlabathi lizongezwa ngokuhlanganiswa ukuze linciphise ukuqina komlilo. Ingasetshenziswa ukwenza igesi noma ngokuqondile njengophethiloli.
Inqubo yokugeleza kwe-coal pullenization
Ukugaya kwamalahle, kusekelwe ikakhulu e-coefficial yokugaya yayo ye-harzburg. I-coeffling yokugcoba efudumele, engcono kakhulu yokugaya (≥ 65), kanye nobuncane be-Harzburg ukugcoba, kuba nzima kakhulu ukugaya (55-60).
Izimo:
① Khetha umshini oyinhloko ngokuya ngokukhishwa kanye nezidingo zobuciko;
② Isicelo Main Main: Thermal pury coal
Ukuhlaziywa kumamodeli wokugaya amalunga
1. I-Pendulum Mill (HC, HCQ Series edilizwayo yamalahle):
Izindleko zokutshala imali okuphansi, okuphuma okuphezulu, ukusetshenziswa kwamandla okuphansi, imishini ezinzile nomsindo ophansi; Ukudonsa kabusha ukuthi izindleko zokusebenza nezindawo zokugcina ziphakeme kunalezo ezimbi.

Ukuphawula (ukucushwa okuyinhloko):
① Uhlelo lokujikeleza oluvulekile lweHongcheng oluvuthayo lumukelwa nge-lignite kanye nelangabi elide linokuqina okuphezulu.
② Uhlaka lwe-plum blossom ngesakhiwo se-pendulum vertical amukela isakhiwo semikhono, esinomphumela ongcono.
③ Idivaysi yokufakazelwa kwe-Explosion yenzelwe uhlelo.
④ Umqoqi we-Dust kanye nepayipi kufanele yakhelwe ukugwema ukunqwabelana uthuli efile ngangokunokwenzeka.
⑤ Okwe-Powder Ukudlulisa uhlelo, kunconywa ukuthi amakhasimende athase igesi edlulisela futhi angeze ngendlela edlulisela i-nitrogen kanye ne-nitric onide system.
2. I-vertical coal mill (HLM vertical Coal Mill):
Ukukhishwa okuphezulu, ukukhiqizwa okuphezulu, isilinganiso sokulungiswa okuphansi, izinga eliphakeme le-automation nobuchwepheshe obuvuthiwe bomoya. Okubi kakhulu kunezindleko eziphezulu zokutshala imali nendawo enkulu yaphansi.

Isigaba I:CUkujaha izinto zokwakha
OmkhuluAmalahleIzinto ezibonakalayo zichotshozwa yi-crusher ku-feed fix (15mm-50mm) ezingangena kugaya lokugaya.
Isiteji2: Gukugoqa
OkuchotshoziweAmalahleIzinto ezincane zithunyelwa kwi-hopper yesitoreji nge-lifter, bese zithumela egumbini lokugaya lesigayo ngokulinganayo futhi ngobuqili ngu-feeder wokugaya.
Isiteji III:Ahlukanisaingxube
Izinto zokwenziwa ezigayiwe zibakwa ngohlelo lokuhlela, futhi i-powder engaqinisekisiwe ihlelwe yi-classifier futhi ibuyele emshinini omkhulu ukuze ugaye kabusha.
IsitejiV: CUkufakwa kwemikhiqizo eqediwe
I-powder evumelana nobunzima igeleza ngepayipi ngegesi futhi ingena ku-Dol Collector ukuze ihlukanise futhi iqoqe. I-powder eqoqwe eqoqiwe ithunyelwa kumkhiqizo oqediwe we-silo ngokudlulisela idivaysi ngokusebenzisa itheku lokukhipha, bese epakishwa yi-powder tanker noma iphakethe elizenzakalelayo.
Izibonelo zohlelo lokusebenza lokucutshungulwa kwamalahle amalahle
Imodeli nenombolo yale mishini: amasethi ama-3 we-HC1700 avulekile uhlelo lokugaya ukugaya ama-mill
Ukucubungula impahla eluhlaza: i-anthracite
Ubunzima bomkhiqizo oqediwe: Ama-200 mesh d92
Umthamo we-Equiple: 8-16 Amathani / ihora
Le phrojekthi ukuhlinzeka ngamalahle adonsayo ohlelweni lwamalahle axoshwe ngohlelo olufudumele olungaphansi komhlaba emayini yeBulanta Coal yeqembu. Usonkontileka ojwayelekile wephrojekthi yiChina Academy of Scaal Science. Kusukela ngo-2009, i-Chinese Academy of Coal Science ibingumlingani we-hongcheng kanye ne-Alliance eqinile. Wonke ama-boiler axoshwe ngamalahle aphonswe namaphrojekthi wamalahle adonsayo amukela isigayo sokugaya i-hongcheng ukuthola ukufana kohlelo. Eminyakeni eyi-6 eyedlule, iHongcheng ibambise ngobuqotho nge-Academy of Coal Science, futhi amaphrojekthi wamalahle agculisayo asakaze kuwo wonke izindawo ezikhiqiza amalahle eChina. Iphrojekthi yamukela amasethi amathathu eRaymond Mills ngohlelo lwe-HC1700 Open Open, oluklanyelwe ngokukhethekile ukugaya amalahle. I-HC1700 ediliziwe yamalahle yokugaya amalahle isebenzisa umjikelezo ovulekile, ukufakwa kwedivaysi yokufakazelwa kwe-provessoon nezinye izindlela, futhi uhlelo luphephile futhi luthembekile. Ukukhishwa kwe-HC1700 Mill kuphakeme ngama-30- 40% aphezulu kunalokho kwendabuko yendabuko yokugaya i-pendulum, okulondolozwa amandla kanye nemvelo-enobungane.
