Isingeniso samalahle
Amalahle awuhlobo lwamaminerali e-carbonized fossil.Ihlelwe yi-carbon, i-hydrogen, i-oxygen, i-nitrogen nezinye izakhi, iningi elisetshenziswa njengabantu.Njengamanje, amalahle anevolumu egciniwe ephindwe izikhathi ezingu-63 kune-petroleum.Amalahle abizwa ngokuthi igolide elimnyama kanye nokudla kwemboni, angamandla amakhulu kusukela ngekhulu le-18.Ngesikhathi seNguquko Yezimboni, kanye nokusungulwa nokusetyenziswa kwenjini yesitimu, amalahle asetshenziswa kabanzi njengophethiloli wezimboni futhi aletha amandla amakhulu angakaze abonwe emphakathini.
Ukusetshenziswa kwamalahle
Amalahle aseChina ahlukaniswe izigaba eziyishumi.Ngokuvamile, amalahle anciphile, amalahle okubhaka, amalahle anamafutha, amalahle egesi, ukuhlangana okubuthakathaka, okungaboshiwe kanye namalahle omlilo amade abizwa ngokuhlanganyela ngokuthi amalahle e-bituminous;Amalahle amancane abizwa ngokuthi i-semi Anthracite;Uma okuqukethwe okuguquguqukayo kungaphezu kuka-40%, kubizwa nge-lignite.
Ithebula lokuhlukaniswa kwamalahle (ikakhulukazi amalahle okupheka)

I-Lignite:
Ikakhulukazi enkulu, ensundu ngokumnyama, icwebezela elimnyama, ukuthungwa okuxekethile;Iqukethe cishe u-40% wezinto eziguquguqukayo, indawo yokushisa ephansi futhi kulula ukubamba umlilo.Ngokujwayelekile isetshenziswa ku-gasification, imboni ye-liquefaction, i-boiler yamandla, njll.
Amalahle e-Bituminous:
Ngokuvamile iyimbudumbudu, incane futhi iyimpushana, ngokuvamile imnyama futhi iyacwebezela, inokwakheka okuhle, iqukethe izinto eziguquguqukayo ezingaphezu kuka-30%, indawo yokushisa ephansi futhi kulula ukuyivutha;Amalahle amaningi e-bituminous ayanamathela futhi kulula ukuwagwaza ngesikhathi sokusha.Isetshenziswa embonini yokupheka, ukuhlanganisa amalahle, ibhoyili kagesi kanye nemboni yokugcwalisa igesi.
I-anthracite:
Kunezinhlobo ezimbili zempushana nezingcezu ezincane, ezimnyama, ezensimbi nezicwebezelayo.Ukungcola okuncane, ukuthungwa okuhlangene, okuqukethwe kwekhabhoni engaguquki ephezulu, kufika ngaphezu kwama-80%;Okuqukethwe okuguquguqukayo kuphansi, ngaphansi kuka-10%, indawo yokuthungela iphezulu, futhi akulula ukubamba umlilo.Inani elifanele lamalahle nomhlabathi liyongezwa ukuze kushiswe ukuze kuncishiswe amandla omlilo.Ingasetshenziselwa ukwenza igesi noma ngokuqondile njengophethiloli.
Ukugeleza kwenqubo yokuphonswa kwamalahle
Ukuze kugaywe amalahle, kusekelwe ikakhulukazi ku-coefficient yayo yokugaya i-Harzburg.Ukukhula kwe-coefficient ye-Harzburg grindability, ngcono ukugaya (≥ 65), kanye ne-Harzburg grindability coefficient encane, kuba nzima ukugaya (55-60).
Amazwana:
① khetha umshini oyinhloko ngokuya ngokuphumayo kanye nezidingo zokulunga;
② Isicelo esiyinhloko: amalahle ashisiwe ashisayo
Ukuhlaziywa kwamamodeli wokugaya
1. Isigayo se-Pendulum (HC, HCQ uchungechunge lwe-pulverized coal mill):
Izindleko eziphansi zokutshala izimali, ukukhishwa okuphezulu, ukusetshenziswa kwamandla okuphansi, okokusebenza okuzinzile nomsindo ophansi;I-drawback ukuthi izindleko zokusebenza nezokulungisa ziphakeme kunezigayo eziqondile.

Amazwana (ukumisa okuyinhloko):
① Uhlelo lwesekethe oluvulelekile lwe-Hongcheng lusetshenziselwa amalahle e-lignite namalangabi amade anokuqina okukhulu.
② Uhlaka lwe-plum blossom enesakhiwo se-pendulum esime mpo samukela isakhiwo semikhono, esinomthelela ongcono.
③ Idivayisi yokuqinisekisa ukuqhuma yakhelwe isistimu.
④ Umqoqi wothuli namapayipi kuzoklanywa ukugwema ukunqwabelana kothuli ekhoneni elifile ngangokunokwenzeka.
⑤ Ngohlelo lokudlulisa impushana, kunconywa ukuthi amakhasimende asebenzise ukuthuthwa kwegesi futhi ngokwemibandela engeze uhlelo lokudlulisa i-nitrogen kanye ne-nitric oxide yokuthola.
2. Isigayo samalahle esime mpo (isigayo samalahle esime mpo se-HLM):
Okukhiphayo okuphezulu, ukukhiqizwa kwezinga elikhulu, izinga eliphansi lokulungisa, izinga eliphezulu lokuzishintshanisa nobuchwepheshe bomoya oshisayo obuvuthiwe.Okubi yizindleko eziphezulu zokutshala imali kanye nendawo enkulu yaphansi.

Isigaba I:Cukuphuthuma kwezinto zokusetshenziswa
EnkuluAmalahleimpahla igaywa yi-crusher kuze kube yi-feed fineness (15mm-50mm) engangena emshinini wokugaya.
IsitejiII: Gukugoqa
OchotshoziweAmalahleizinto ezincane zithunyelwa ku-hopper yokugcina nge-elevator, bese zithunyelwa ekamelweni lokugaya le-mill ngokulinganayo futhi ngobuningi yi-feeder yokugaya.
Isigaba III:Hlelaing
Izinto ezigayiwe zihlelwa ngesistimu yokugreda, futhi impushana engafanelekile ihlelwa ngokwezigaba bese ibuyiselwa emshinini omkhulu ukuze igaywe kabusha.
IsitejiV: Cukuqoqwa kwemikhiqizo eqediwe
Impushana ehambisana nokucoleka igeleza epayipini negesi futhi ingene endaweni eqoqwa uthuli ukuze ihlukaniswe futhi iqoqwe.Impushana eqoqiwe eqoqiwe ithunyelwa esiseleni somkhiqizo oqediwe ngomshini owudluliselayo ngembobo yokukhipha, bese ihlanganiswa ne-powder tanker noma i-automatic packer.
Izibonelo zohlelo lokusebenza lwempushana yamalahle
Imodeli kanye nenombolo yale mishini: Amasethi ama-3 we-HC1700 evulekile yesistimu yokugaya izigayo
Ukucubungula impahla eluhlaza: I-anthracite
Ubuhle bomkhiqizo ophelile: 200 mesh D92
Izinsizakusebenza: 8-12 amathani / ihora
Le phrojekthi iwukuhlinzeka ngamalahle ahlutshiwe kubhayela obaselwa ngamalahle wesistimu yokushisisa ngaphansi komhlaba emayini yamalahle yaseBulianta yeqembu.Usonkontileka jikelele wale phrojekthi yi-China Academy of Coal Sciences.Kusukela ngo-2009, i-Chinese Academy of Coal Sciences ibinguzakwethu wamasu we-Hongcheng kanye nomfelandawonye oqinile.Wonke amaphrojekthi kabhayela obaselwa ngamalahle kanye namaphrojekthi amalahle acijile asebenzisa isigayo sokugaya sase-Hongcheng ukuze sifaniswe nesistimu.Kule minyaka engu-6 edlule, i-Hongcheng ibambisene ngobuqotho ne-Academy of Coal Sciences, futhi amaphrojekthi agayiwe okugaywa kwamalahle asesabalele kuzo zonke izindawo eziyinhloko ezikhiqiza amalahle e-China.Le phrojekthi ithatha amasethi amathathu ezigayo zikaRaymond ezinohlelo lwesekethe oluvulekile lweHC1700, eziklanyelwe ngokukhethekile ukugaya amalahle agayiwe.I-Hc1700 yokugaya amalahle egayiwe yamukela isekethe evulekile, ukufakwa kwethuluzi elivikela ukuqhuma nezinye izindlela, futhi uhlelo luphephile futhi luthembekile.Ukukhishwa kwesigayo se-HC1700 kuphakeme ngo-30-40% kunomshini wokugaya we-pendulum wendabuko, okonga amandla futhi okuvumelana nemvelo.
