Ekukhiqizweni kokudla kwesimanje, umugqa wokukhiqiza ama-pellet umelela umongo womsebenzi wonke wokucubungula. Lapho kuvela amaphutha emishini, awaphazamisi nje kuphela isigaba sokugaya ama-pellet kodwa abuyela emuva ekugayeni nasekuxubeni, bese eqhubekela phambili ekupholiseni nasekupakisheni. Izindleko zesikhathi sokungasebenzi esingahleliwe emshinini wokudla ophakathi nendawo kuya omkhulu zingadlula izinkulungwane zamaRandi ngehora uma kubhekwa ukulahleka komkhiqizo, ukungasebenzi kahle kwabasebenzi, kanye nokubambezeleka kokulethwa. Lesi sihloko sihlola amaphutha avame ukuhlangatshezwa emigqeni yokukhiqiza ama-pellet, sihlaziya izimbangela zawo eziyisisekelo, futhi siveza izixazululo ezihlelekile ezisekelwe ezimisweni zobunjiniyela bemishini kanye nolwazi lwasensimini. Inhloso akukhona ukukhuthaza noma yiluphi uhlobo kodwa ukuhlinzeka abakhiqizi bokudla ngezinhlaka zokuxilonga ezisebenzisekayo ezinciphisa isikhathi esimaphakathi sokulungisa nokuthuthukisa ukusebenza kahle kwemishini iyonke.
Ukuvaleka Kokufa kanye Nokusatshalaliswa Kwezinto Ezingalingani
Ukuhlonza Izimpawu
Abaqhubi bavame ukubona ukuvinjelwa komshini ngokusebenzisa izinkomba ezintathu: ukunyuka okungazelelwe komshini oyinhloko, ukwehla okukhulu kokukhishwa kwe-pellet endaweni yokukhipha, kanye noshintsho oluzwakalayo emsindweni wokusebenza kwe-pellet mill - ovame ukuchazwa njengomsindo "wokugaya ongenalutho". Ezimweni ezimbi kakhulu, iphinikhodi yokugunda yokuphepha izophuka, okubangela ukuvala okuzenzakalelayo.
Ukuhlaziywa Kwembangela Eyinhloko
Ukuvaleka kwe-die akuvamile ukuvela esicini esisodwa. Uphenyo lwasensimini ezindaweni eziningi zokukhiqiza lwembula iphethini efanayo: ukusebenzisana phakathi kwekhwalithi yokulungisa izinto kanye nokungafani kwencazelo ye-die. Lapho ukulungiswa kwe-steam kwehluleka ukufeza okuqukethwe komswakama okuqondiwe okungu-15-17% kanye nokushisa okungu-80-85°C, ukudla okuhlanganisiwe kungena ku-die kungenalutho. Izinto zibe sezihlangana ngokungalingani emigodini ye-die, kudala izindawo zokucindezela ngokweqile ezincipha kancane kancane indawo ye-die esebenzayo.
Ingxenye yesibili efaka isandla ukuqongelela kwezingcezu zezinhlawulo nezingcezu zensimbi emigodini yedayi. Ngisho noma kufakwe ama-separator kamagnetic phezulu, izinhlayiya ze-ferrous ezingaphansi kwamamilimitha zingangena ezindongeni zemigodi yedayi, okwandisa ama-friction coefficients ngo-15-30% emijikelezweni eminingana yokukhiqiza.
Isixazululo Esihlelekile
Indlela yokulungisa ilandela inqubo enezigaba ezintathu:
Misa ukufaka ukudla, shintshela engxubeni yembewu kawoyela (ngokuvamile okuqukethwe uwoyela okungu-5-8%) bese usebenzisa umshini wokugaya ngesivinini esincishisiwe imizuzu emi-3-5. Uwoyela usebenza njengesithambisi, ukhipha kancane kancane izinto ezihlanganisiwe ezivela emigodini yokudaya. Le ndlela ibuyisa cisheAma-70% ezidumbu ezivinjiwengaphandle kokudinga ukususwa kwedayi.
Uma iSigaba 1 sihluleka, susa i-die assembly bese uhlola umugqa ngamunye wembobo ngaphansi kokukhanya okwanele. Sebenzisa isibhamu sokuhlanza esinomoya esinezinaliti zensimbi eziqinile ezihambisana nobubanzi bembobo yokuqala. Ungalokothi usebenzise amathuluzi okuhlanza amakhulu kakhulu, njengoba akhulisa imbobo ye-die futhi ashintsha unomphela isilinganiso sokucindezela.
Buyekeza amahora okugcina angu-48 okugcina ezingobo zokukhiqiza. Lungisa ukucindezela komusi ukuze ugcine ukuqinaIbha engu-2.0–2.5endaweni yokungena ye-conditioner. Qinisekisa ukuthi ijika lokukhuphuka kwesivinini se-feeder livumela idayisi ukuthi ifinyelele ukulingana kokushisa ngaphambi kokuba kuqale ukudla okugcwele umthwalo - isikhathi sokufudumeza semizuzu emi-3-5 ngesilinganiso sokudla esingu-50% sinciphisa kakhulu izehlakalo zokuvaleka kokuqala okubandayo.
Ikhwalithi ye-Pellet engaguquguquki kanye ne-Low Durability Index
Ukuhlonza Izimpawu
Ukungahambisani kwekhwalithi kubonakala njengama-pellet anobude obuhlukahlukene (ukubekezelelana okuqondiwe ±10% kudluliwe), izinhlawulo eziningi kakhulu ekukhishweni okubandayo (ngaphezu kuka-3% ngesisindo), kanye ne-Pellet Durability Index eyehla ngaphansi kwesilinganiso somkhakha se-95% yokudla kwenkukhu or 97% wokudla okumanzi.
Ukuhlaziywa Kwembangela Eyinhloko
Inkomba yokuqina kwe-pellet ilawulwa yizinto ezintathu ezincikene: isilinganiso sokucindezela kwe-die, ukusatshalaliswa kosayizi wezinhlayiya zezinto ezisemhlabeni, kanye nokusebenza kwe-binder ngaphansi kwezimo ezithile zokulungisa. Ukungatholakali kahle okuvamile kubangelwa ukuqina okungekuhle kuphela ukuguga kwe-die. Ngenkathi ukuguga kwe-die kuyisici - i-die esebenza ngaphezu kwamathani angu-50,000-60,000 okudlula ngokuvamile ikhombisa ukwandiswa kwembobo okulinganiselwe - imbangela evame kakhulu usayizi wezinhlayiya ongaguquki kusukela esigabeni sokugaya. Lapho umshini wokugaya i-hammer ukhiqiza ukusatshalaliswa kosayizi wezinhlayiya obanzi ngokuphambuka okujwayelekile kwe-geometric okungaphezu kuka-2.0, izinhlawulo zigcwalisa izikhala eziphakathi kwezinhlayiya ezinkulu embobeni ye-die, okudala izindiza zokusika ezibuthakathaka ku-pellet eqediwe.
Isixazululo Esihlelekile
Uchungechunge lokuxilonga kufanele luqale phezulu:
Qoqa amasampula lapho kuphuma khona i-mixer njalo emahoreni amabili ukuze usebenze ngokugcwele. Sebenzisa i-Ro-Tap sieve shaker enezihluzo ezingama-micron angu-300, 500, 1000, kanye no-2000. I-D50 eqondiwe yokudla kwenkukhu okujwayelekile yi-Ama-micron angu-600–700ngokuphambuka okujwayelekile kwejometri ngaphansi kuka-1.8. Uma ukuphambuka kudlula lo mkhawulo, hlola isimo sesikrini se-hammer mill kanye nokuvuleka kwe-hammer tip.
Kala umehluko wokushisa phakathi kokungena kwe-conditioner kanye ne-outlet. Ukwehla okungaphezu kuka-5°C phakathi kokungena kwe-steam kanye ne-conditioned mash kubonisa ukulahlekelwa ukushisa nge-conditioner barrel - ngokuvamile ngenxa yokungabi namandla okushisa noma ukunqwabelana kwe-condensate emgqeni we-steam. Faka i-steam trap ngaphakathi kwamamitha amathathu ukusuka kokungena kwe-conditioner bese uqinisekisa ukusebenza kwayo masonto onke.
Qinisekisa ukuthi isilinganiso sokucindezela idayisi (ubude bembobo obusebenzayo obuhlukaniswe ngobubanzi bembobo) sihambisana nokwakheka. Kokuphakelwa kwenkukhu okujwayelekile okunomswakama ongu-12-14% ngemuva kokupholisa, isilinganiso sokucindezela sika1:8 kuya ku-1:10kufanelekile. Kokudla kwezilwane ezifuywayo okune-fiber ephezulu, izilinganiso1:10 kuya ku-1:12inikeza ukuqina okungcono.
Ukwehla Komkhiqizo Ngaphandle Kwesibonakaliso Esicacile Sephutha
Ukuhlonza Izimpawu
Lena inkinga yokukhiqiza ecashile kakhulu: umshini wokugaya ama-pellet uyaqhubeka nokusebenza ngaphandle kwama-alamu noma amaphutha abonakalayo, kodwa umkhiqizo ojwayelekile wehla kancane kancane ngo-10–20%amasonto amaningana. Abaphathi bokukhiqiza bavame ukwamukela lokhu “njengokuguguleka okuvamile” futhi bakhokhele ngokwandisa amahora okusebenza, okufihla inkinga eyisisekelo futhi kwandise izindleko zamandla.
