Isingeniso kumalahle
Amalahle uhlobo lwamaminerali asetshenziswe njenge-carbon. Ahlelwe yi-carbon, i-hydrogen, i-oxygen, i-nitrogen nezinye izinto, iningi lawo lisetshenziswa njengophethiloli ngabantu. Njengamanje, amalahle anenani eligciniwe eliphindwe izikhathi ezingu-63 kune-petroleum. Amalahle ayebizwa ngokuthi igolide elimnyama futhi ukudla kwezimboni, yiwona amandla amakhulu kusukela ngekhulu le-18. Ngesikhathi seNguquko Yezimboni, kanye nokusungulwa nokusetshenziswa kwenjini yomusi, amalahle asetshenziswa kabanzi njengophethiloli wezimboni futhi aletha amandla amakhulu angakaze abonwe emphakathini.
Ukusetshenziswa kwamalahle
Amalahle aseShayina ahlukaniswe ngezigaba eziyishumi. Ngokuvamile, amalahle angaxubile, amalahle acoka, amalahle anamafutha, amalahle egesi, amalahle aqinile, angaxhunyekile kanye namalahle avutha ilangabi elide abizwa ngokuthi amalahle abituminous; Amalahle angaxubile abizwa ngokuthi i-semi Anthracite; Uma okuqukethwe okuguquguqukayo kungaphezu kuka-40%, kubizwa ngokuthi i-lignite.
Ithebula lokuhlukaniswa kwamalahle (ikakhulukazi amalahle okupheka)

I-Lignite:
Ikakhulukazi inkulu, insundu emnyama, ikhanya kakhulu, ukuthungwa okuxekethile; Iqukethe cishe u-40% wezinto eziguquguqukayo, indawo yokubasa ephansi futhi kulula ukubamba umlilo. Ngokuvamile isetshenziswa ekwenzeni igesi, embonini yoketshezi, kubhoyila kagesi, njll.
Amalahle e-bituminous:
Ngokuvamile iyi-granular, incane futhi iyimpuphu, ikakhulukazi imnyama futhi iyacwebezela, inokwakheka okuhle, iqukethe izinto ezingaphezu kuka-30% eziguquguqukayo, indawo yokushisa ephansi futhi kulula ukuyithungela; Amalahle amaningi e-bituminous ayanamathela futhi kulula ukuwalahla ngesikhathi sokusha. Asetshenziswa ekuphekeni, ekuxubeni amalahle, embonini yebhoyila yamandla kanye ne-gasification.
I-Anthracite:
Kunezinhlobo ezimbili zempuphu nezingcezu ezincane, ezimnyama, ezensimbi nezicwebezelayo. Ukungcola okuncane, ukuthungwa okuqinile, okuqukethwe okuphezulu kwekhabhoni okuqinile, kufika ngaphezu kuka-80%; Okuqukethwe okuguquguqukayo kuphansi, ngaphansi kuka-10%, indawo yokushisa iphakeme, futhi akulula ukubamba umlilo. Inani elifanele lamalahle nomhlabathi kufanele lifakwe ukuze kushiswe ukuze kuncishiswe amandla omlilo. Ingasetshenziswa ukwenza igesi noma ngqo njengophethiloli.
Ukugeleza kwenqubo yokugaya amalahle
Ekugayeni amalahle, kusekelwe kakhulu ku-coefficient yayo yokugaya iHarzburg. Uma i-coefficient yokugaya iHarzburg inkulu, kulapho ukugaya kungcono khona (≥ 65), futhi uma i-coefficient yokugaya iHarzburg incane, kulapho ukugaya kuba nzima khona (55-60).
Amazwi:
① khetha umshini oyinhloko ngokuya ngezidingo zokukhipha kanye nokuqina;
② Isicelo esiyinhloko: amalahle ashisiwe ashisayo
Ukuhlaziywa kwamamodeli okugaya
1. Umshini wokugaya amalahle we-pendulum (HC, umshini wokugaya amalahle we-HCQ ochungechungeni):
Izindleko zokutshalwa kwezimali eziphansi, umkhiqizo ophezulu, ukusetshenziswa kwamandla okuphansi, imishini ezinzile nomsindo ophansi; Inkinga ukuthi izindleko zokusebenza nokugcinwa ziphakeme kunezomshini omile.

Amazwi (ukucushwa okuyinhloko):
① Uhlelo lwesekethe evulekile olune-patent yaseHongcheng lusetshenziswa kumalahle e-lignite kanye nelangabi elide elinokuguquguquka okuphezulu.
② Uhlaka lwe-plum blossom olunesakhiwo se-pendulum esiqondile lusebenzisa isakhiwo se-sleeve, esinomphumela ongcono.
③ Idivayisi engangeni ukuqhuma yenzelwe uhlelo.
④ Umqoqi wothuli kanye nepayipi kumele kwakhiwe ukuze kugwenywe ukunqwabelana kothuli endaweni engapheli ngangokunokwenzeka.
⑤ Kuhlelo lokuhambisa i-powder, kunconywa ukuthi amakhasimende asebenzise uhlelo lokuhambisa igesi bese efaka ngokwemibandela uhlelo lokuhambisa i-nitrogen kanye nohlelo lokuthola i-nitric oxide.
2. Umshini wokugaya amalahle oqondile (umshini wokugaya amalahle oqondile we-HLM):
Umkhiqizo ophezulu, ukukhiqizwa okukhulu, izinga eliphansi lokugcinwa, izinga eliphezulu lokuzenzakalela kanye nobuchwepheshe bomoya oshisayo obuvuthiwe. Inkinga izindleko zokutshalwa kwezimali eziphezulu kanye nendawo enkulu yephansi.

Isigaba I:Cukushesha kwezinto zokusetshenziswa
InkuluAmalahleIzinto ezisetshenziswayo zichotshozwa yi-crusher kuze kube yilapho zinobuncane bokuphakela (15mm-50mm) obungangena emshinini wokugaya.
IsitejiII: Gukugoqa
AbachotshoziweAmalahleIzinto ezincane zithunyelwa endaweni yokugcina izinto nge-lifti, bese zithunyelwa ekamelweni lokugaya lesitsha ngokulinganayo nangobuningi yi-feeder ukuze zigaywe.
Isigaba III:Hlela ngezigabaing
Izinto ezigayiwe zilinganiswa ngohlelo lokulinganisa, kanti impuphu engafaneleki ilinganiswa ngohlelo lokuhlukanisa bese ibuyiselwa emshinini oyinhloko ukuze igaywe kabusha.
IsitejiV: Cukuqoqwa kwemikhiqizo eqediwe
Impuphu evumelana nobuncane igeleza ngepayipi kanye negesi bese ingena eqoqweni lokuqoqa uthuli ukuze ihlukaniswe futhi iqoqwe. Impuphu eqoqwe ithunyelwa esigungwini somkhiqizo oqediwe ngedivayisi yokudlulisa ngembobo yokukhipha, bese ipakishwa yithangi lempuphu noma i-automatic packer.
Izibonelo zokusetshenziswa kokucubungula i-powder yamalahle
Imodeli nenani lale mishini: Amasethi ama-3 emishini yokugaya yesistimu yesekethe evulekile ye-HC1700
Ukucubungula izinto zokusetshenziswa: i-Anthracite
Ubuncane bomkhiqizo oqediwe: 200 mesh D92
Umthamo Wemishini: Amathani angu-8-12 / ihora
Lo msebenzi uhlose ukuhlinzeka ngamalahle acoliwe ebhoyila elisebenzisa amalahle lesistimu yokushisa engaphansi komhlaba emayini yamalahle yaseBulianta yeqembu. Usonkontileka ojwayelekile walo msebenzi yi-China Academy of Coal Sciences. Kusukela ngo-2009, i-Chinese Academy of Coal Sciences ibilokhu ingumlingani oqavile we-Hongcheng futhi inobudlelwano obuqinile. Wonke amaphrojekthi amalahle asebenzisa amalahle kanye namaphrojekthi amalahle acoliwe asebenzisa umshini wokugaya wase-Hongcheng ukuze kufaniswe uhlelo. Eminyakeni eyi-6 edlule, i-Hongcheng ibambisene ngobuqotho ne-Academy of Coal Sciences, futhi amaphrojekthi okugaya amalahle acoliwe asabalale kuzo zonke izindawo ezikhiqiza amalahle amakhulu e-China. Lo msebenzi usebenzisa amasethi amathathu e-Raymond mills anohlelo lwesekethe oluvulekile lwe-HC1700, oluklanyelwe ngokukhethekile ukugaya amalahle acoliwe. Umshini wokugaya amalahle ocoliwe we-Hc1700 usebenzisa isekethe evulekile, ukufakwa kwedivayisi engaqhumi nezinye izindlela, futhi uhlelo luphephile futhi luthembekile. Umkhiqizo womshini wokugaya we-HC1700 uphakeme ngo-30-40% kunowomshini wokugaya wendabuko we-pendulum, ogcina amandla futhi onakekela imvelo.
