HPGR High Pressure Grinding Mill
Isicelo
I-single-drive high high-high-high rolling roll yenzelwe ngokukhethekileyo ukucola iintsimbi zesamente kwangaphambili, inkunkuma yezimbiwa, iintsimbi ezikrwada njalo njalo zibe ziigranule ezincinci, ukutyumza iiminerali zesinyithi (ore iron, ores manganese, copper ores). , i-lead-zinc ores, i-vanadium ores kunye nezinye) kunye nokusila iiminerali ezingezizo ezentsimbi (i-coal gangues, i-feldspar, i-nephe-line, i-dolomite, i-limestone, i-quartz, njl.njl.) ibe ngumgubo.
Ulwakhiwo kunye noMgaqo wokuSebenza
Umzobo woMgaqo wokuSebenza
I-single-drive high pressure grinding roll ithatha umgaqo wokusila we-aggregate extrusion. Omnye ngumqulu omileyo kwaye omnye ngumqulu oshenxisekayo. Imiqulu emibini ijikeleza ngokuchaseneyo ngesantya esifanayo. Izixhobo zingena ukusuka ekuvulekeni kwesondlo esiphezulu, kwaye zigaywe ngenxa yokukhutshwa ngoxinzelelo oluphezulu kwisithuba semiqulu emibini, kwaye ikhutshwe ukusuka ezantsi.
Qhuba inxalenye
Inye kuphela i-motor drive efunekayo, amandla ahanjiswa ukusuka kumqulu omileyo ukuya kumqulu oshukumayo ngokusebenzisa inkqubo yegiya, ukwenzela ukuba imiqulu emibini ihambelane ngokupheleleyo ngaphandle kokukhuhlana. Umsebenzi wonke usetyenziselwa ukukhutshwa kwezinto eziphathekayo, kwaye izinga lokusetyenziswa kwamandla liphezulu, eligcina i-45% yombane xa kuthelekiswa nomqulu oqhelekileyo wokugaya uxinzelelo.
Inkqubo yokufaka uxinzelelo
Inkqubo edibeneyo yokufaka uxinzelelo lomatshini wentwasahlobo yenza ukuba umqulu oshukumayo uphephe ukuguquguquka. Xa kungena into yangaphandle yentsimbi, inkqubo yokusetyenziswa koxinzelelo lwentwasahlobo ibeka umva ngokuthe ngqo kwaye iphendule kwangethuba, iqinisekisa ukuba izinga lokusebenza liphezulu ukuya kuma-95%; Ngelixa umqulu wesiqhelo wokusila woxinzelelo oluphezulu wenza ukuba kuthintelwe, ioyile yehydraulic kufuneka ikhutshwe ngombhobho wokuthomalalisa uxinzelelo. Isenzo sibambezelekile, esinokubangela umonakalo kwi-roll surface okanye ukungasebenzi kakuhle kwe-hydraulic system.
Roll umphezulu
Umphezulu we-roll ujongene ne-welded kunye ne-alloy wear-resistant welding material, kwaye ukuqina kunokufikelela kwi-HRC58-65; uxinzelelo luhlengahlengiswa ngokuzenzekelayo kunye nezinto eziphathekayo, ezingaphumeleli kuphela injongo yokugaya, kodwa zikhusela i-roll surface; umqulu oshukumayo kunye nomqulu omileyo usebenza ngolungelelwano ngaphandle kokutyibilika. Ngoko ke, ubomi benkonzo ye-roll surface buphezulu kakhulu kunoluhlu oluqhelekileyo lokugaya uxinzelelo oluphezulu.
Iimpawu eziphambili zobuGcisa
■Ubuchule bokusebenza obuphezulu. Xa kuthelekiswa nezixhobo zemveli zokutyumza, amandla okusebenza anyuka ngama-40 - 50%. Umthamo wokucubungula wePGM1040 unokufikelela malunga ne-50 - 100 t/h, ngamandla angama-90kw kuphela.
■Ukusetyenziswa kwamandla aphantsi. Ngokwendlela enye yokuqhuba, idinga injini enye kuphela ukuqhuba. Ukusetyenziswa kwamandla kuphantsi kakhulu. Xa kuthelekiswa nemveli kabini drive HPGR, inokunciphisa ukusetyenziswa kwamandla nge 20 ~ 30%.
■Umgangatho oFanelekileyo wokuNxhathisa. Ngokuqhuba kwemoto enye kuphela, ukusebenza kongqamaniso lwemiqulu emibini kuhle kakhulu. Ngeendawo ze-welding zokunxiba, ii-rolls zinomgangatho olungileyo wokunxiba kwaye zinokugcinwa ngokulula.
■Inqanaba lokuSebenza eliPhezulu: ≥ 95%. Ngoyilo lwesayensi, izixhobo zinokucinezelwa liqela loxinzelelo oluphezulu lwentwasahlobo. Uxinzelelo olusebenzayo lunokulungelelaniswa ngokuzenzekelayo njenge-compress yeqela lasentwasahlobo. Akukho ndawo yokungasebenzi kakuhle.
■I-Automation ephezulu kunye nohlengahlengiso olulula. Ngaphandle kwenkqubo ye-hydraulic, kukho izinga eliphantsi lokungasebenzi.
■ Umphezulu oqengqelekayo udityaniswe ngesixhobo sokuwelda esingagugiyo, esinokuqina okuphezulu kunye nokungagugi kakuhle; Uxinzelelo oluya entwasahlobo luvela kumandla okusabela kwizinto eziphathekayo, kwaye uxinzelelo luhlala lulinganisa, olungaphumeleli nje injongo yokutyumza, kodwa lukhusela i-roll surface; umqulu oshukumayo kunye nomqulu omileyo zidityanisiwe kwaye ziqhutywa yinkqubo yegiya, kwaye isantya silungelelaniswe ngokupheleleyo, ngaloo ndlela sinqanda ukungqubana kokutyibilika phakathi kwezinto kunye nomgangatho wokuqengqeleka. Ngoko ke, ubomi benkonzo buphezulu kakhulu kunobo be-HPGR yokuqhuba kabini.
■ Ubume obubambeneyo kunye nesithuba esincinci somgangatho.
