Ukukhetha kwama-coal mill 1: Isigaye samalahle esiphansi

Ummeleli ojwayelekile wejubane eliphansi lamalahle amalahle yibhola lebhola. Umgomo osebenzayo yile: Imoto ephezulu yamandla ngegiya ukushayela lokhu kujikeleza okusindayo kwepuleti, ibhola lensimbi okulula lijikeleze endaweni ethile bese liwela phansi, ngomthelela webhola lensimbi ku-coal naphakathi Ibhola lensimbi, phakathi kwebhola lensimbi nepuleti lomqaphi, amalahle asemhlabathini. Amalahle angenakuqhathaniswa angenakuqhathaniswa ahlukaniswe lapho ugeleza ohlukanisayo we-coarse powder ngemuva kwesigayo sebhola, bese ethunyelwa kwipuleti eyindilinga kusuka ku-powder tube yokugaya kabusha. Ngaphezu kokuhambisa i-poal powder, umoya oshisayo futhi udlala indima yokumisa amalahle. Ngakho-ke, umoya oshisayo ubizwa nangokuthi desticcant ohlelweni lwe-powder. Umkhiqizo unezici zesikhathi eside sokusebenza okuqhubekayo, ukugcinwa okuzinzile, ukuphuma okuzinzile nobukhulu, isilinganiso esikhulu sokusebenza, ukuguqulwa okuphezulu komshini, ukonga umshini wamalahle ophansi, ukonga umshini wamalahle we-spare, ububanzi bamalahle wokugaya nokunye. Isetshenziselwa ikakhulukazi amalahle anzima naphakathi nendawo, ikakhulukazi amalahle anokuqukethwe okuphezulu okunamandla kanye nempahla eqinile enamandla. Kodwa-ke, lokhu kugaya okusheshayo kwe-ball ephansi kuyalingana, kunokusetshenziswa kwensimbi okukhulu, kuthatha umhlaba omningi, futhi kunotshalomali oluphezulu lokuqala. Ngakho-ke i-ball mill ilungele ukusebenza komthwalo okugcwele.

Uhlobo lwe-COAL MIT MILD 2:I-Medium Speed ​​Coal Mill 

Ijubane eliphakathi nendawo yamalahle lamaCoal liyaziwa nangokuthi i-vertical Coal Mill, elibonakaliswa yizingxenye zokugaya ezakhiwa amaqembu amabili wokunyakaza okuhlobene nomzimba wokugaya. Amalahle ancishisiwe futhi emhlabathini phakathi kwezindawo zemizimba emibili yokugaya futhi zichotshozwa. Ngasikhathi sinye, umoya oshisayo ngokusebenzisa isigayo somisa amalahle bese uthumela amalahle adonswayo kusahlukanisi engxenyeni engenhla yendawo yokugaya. Ngemuva kokuhlukaniswa, amalahle asungula usayizi othile wezinhlayiya asuswa ngaphandle kwesigayo ngokugeleza komoya, futhi amalahle angcolisiwe abuyiselwa endaweni yokugaya ukuze ahlele kabusha. I-Medium Speed ​​Coal Mill inezinzuzo zemishini ehlanganisiwe, i-Footprint encane, ukusindisa amandla okusetshenziswa kwamandla (cishe ama-50% ~ 75% we-Ball Mill), Umsindo ophansi, okhanyayo wokulawula ukusebenza. Kepha akufanelekile ukugaya amalahle anzima.

Ukukhetha kwama-Cooal Mill Ukukhetha 3: Ijubane eliphakeme lamalahle

Ijubane le-High-Speed ​​Coal Mill lingu-500 ~ 1500 r / min, elihlanganiswa ikakhulukazi i-rotor ephezulu ye-rotor kanye negobolondo lokugaya. Ukugaya okuvamile kokugaya kanye nokugaya isando nokunye. Esigangeni, amalahle aphoqelelwa ukushayisana phakathi komthelela wesivinini esikhulu kanye negobolondo lokugaya kanye nokushayisana phakathi kwamalahle. Lolu hlobo lokugaya kwamalahle kanye ne-pury coal uhlukanise ifomu eliphelele, isakhiwo silula, iCompact, ukutshalwa kwemali kokuqala kuphansi, ikakhulukazi okuqukethwe okuphezulu kokugaya umswakama okuphezulu nokuqukethwe okuphezulu, okulula ukugaya amalahle we-buruminous. Kodwa-ke, ngoba ipuleti lomthelela ligcwaliswa ngokuqondile futhi ligqokwa ngokugeleza komoya, impilo yalo ngokuvamile lingaba ngu-1000h lapho ugaya i-lignite, ukufakwa njalo, futhi okuqukethwe kwamanzi kwamalahle emhlabathini akufanele kube phezulu kakhulu, okuvame ukusetshenziswa Iqonde ngqo ama-boilers ezitshalweni zamandla, futhi akufanele asetshenziselwe ama-Blast Funec umjovo workshop.

Izinhlobo ezintathu ezingenhla zokukhethwa kwemishini yokugaya amalahle zinezinzuzo nobubi, ekukhetheni imishini yokugaya amalahle, kuyadingeka ukubheka ukukhethwa okuphelele kohlelo lokudiliza. Uhlelo lwe-powder lungahlukaniswa ngezigaba ezimbili: uhlobo oluqondile lokushaya kanye nohlobo lokugcina oluphakathi (olubizwa ngokuthi uhlobo lwesitoreji). Kuhlelo lokushaya okuqondile, amalahle angena emgqeni wamalahle ngesigayo samalahle abese eshaywa ngqo esithandweni sokuhlanganiswa. Ohlelweni lwe-stor Cellverization, amalahle adonswayo agcinwa okokuqala emgqonyeni wamalahle osuselwa emgqonyeni wamalahle, bese ngokuya ngezidingo zomthwalo wamalahle, kuthunyelwe amalahle asuka emgqonyeni wamalahle egayiwe esithandweni sokuhlangana. Izinhlelo ezahlukene ze-pulving zilungele izinhlobo ezahlukene zokukhethwa kwemishini yamalahle nokugaya kwamalahle. Ngokusho kohlelo lokugawulwa, safingqa isisekelo esilandelayo sokukhethwa kwamalahle amalahle:

. Ukulahleka kwamanga ngezansi okuqinile, ukusebenza kwamalahle okuvuthayo kuyavutha, futhi ubuciko bamalahle abadiliziwe buhlangabezana nezidingo zesigayo samakhola.
