Ball Mill Liner

I-ball liner yinto enxitywayo-kumgca onganyangekiyo ofakwe ngaphakathi kwesixhobo sokusila ukukhusela iqokobhe lentsimbi kwisenzo sokusila semithombo yeendaba zokusila kunye nezinto ezilungiswayo. Ezi liner ngokwesiqhelo zenziwe ngezitena eziphezulu zealumina zealumina ezixineneyo kwaye zisetyenziswa naphina apho kufuneka ukucolwa kokucoleka - kwemigodi, ukusetyenzwa kwezimbiwa, ukuveliswa kwesamente, ukwenziwa kweseramikhi, kunye nokwenziwa kombane.

Inzuzo engundoqo ye-ceramic ball mill liner kukuphila ixesha elide. Intsimbi okanye irabha yerabha kwi-mill yebhola inokuhlala iinyanga ezi-6-18, kuxhomekeke kwisicelo. -Ilayini ye-alumina yeceramic ephezulu, efakwe ngokufanelekileyo, ingasebenza iminyaka emi-3-5 okanye ngaphezulu. Loo mahluko uguqulela ngokuthe ngqo kukuvalwa okumbalwa kokuhombisa, ukugcinwa kokusebenza okuphantsi, kunye neeshedyuli zemveliso ezinokuqikelelwa ngakumbi.

Yiyiphi ingxaki eyisombululayo? Kwibhola yebhola, i-lining ithatha ukubetha rhoqo kwintsimbi okanye i-ceramic media media. Ngokuhamba kwexesha, iilayini eziqhelekileyo ziphuhlisa iipatheni zokunxiba ezingalinganiyo, ukuqhekeka, okanye ukukhulula. Nje ukuba i-liner isilele, iqokobhe lentsimbi liyavezwa - kwaye ukulungisa iqokobhe eligugileyo kubiza ngaphezulu kakhulu kunokutshintsha ilina. I-ceramic liner ene-design edibeneyo kunye nelahleko ephantsi yokugqoka isusa ezi ndlela zokungaphumeleli, igcina i-mill isebenza kude kube yi-relining ecwangcisiweyo.

Kumthengi othengisiweyo, oku kuthetha ukubonelela ngesisombululo abathengi basemigodini, kwisamente, nakwimizi-mveliso yeeseramikhi abasidinga ngokwenene - kwaye baphinde iiodolo ezivela kwimisebenzi ebone umahluko.

Zintlanu izinto ezibonisa ukuba i-ball lining ihlala ixesha elingakanani.

Izinga lokunxiba.Le yeyona metric ibalulekileyo. Isitena esicothayo siya kuhlala sisebenza ixesha elide. Ibanga le-TL92S likaTecera lilahlekelwa kuphela yi-0.005% yobunzima bayo kwiiyure ezingama-24 phantsi kweemeko zovavanyo oluqhelekileyo - ngokumalunga nesiqingatha sokuphulukana nezitena ezisemgangathweni ezingama-92%. Isiqingatha somlinganiselo wokunxitywa sithetha malunga nokuphinda kabini ubomi benkonzo.

Uyilo lonxibelelwano.Uyilo lwezitena ze-trapezoid lubanzi kwelinye icala kwaye lincinci kwelinye. Xa zibekwe ecaleni, isiphelo esibanzi sesitena sijika sijonge kwincam emxinwa kwesinye. Le interlock yomatshini igcina i-lining yomelele nokuba i-epoxy adhesive ekugqibeleni iyaguga. Kwibhola yokusila, i-lining ifumana ukungcangcazela rhoqo kunye neempembelelo ezivela kwimidiya yokusila - iimeko ezidinwa epoxy ngokuhamba kwexesha. Uqhagamshelo ngoomatshini lubonelela ngenkqubo yokugcina ugcino apho izitena eziqhelekileyo ezixande zinqongopheleyo.

Ukuxinana.Ukuxinana okuphezulu kuthetha ukunyibilika okuphantsi, okuthetha ukufunxwa kancinci kolwelo kunye nokuxhathisa okukhulu kuhlaselo lweekhemikhali olusuka kwi-slurries. Amabanga e-Tecera's TL95 kunye ne-TL97 afumana uxinano lwesambuku ngaphezu kwe-3.68 g/cm³ kunye nokufunxa kwamanzi ngaphantsi kwe-0.01%. Oku kufutshane -zero porosity ikwanqanda ukonakala komkhenkce{7}}kwizingqusho ezikwimozulu ebandayo.

Ubunyulu.Umxholo we-Al₂O₃ ophezulu unika ubunzima, ukunxiba ngakumbi{0}}izitena ezixhathisayo. Kwiiminerali ezininzi zokusila, i-92% yanele. Ukusila kwe-ceramic glaze apho ungcoliseko lunokuchaphazela umbala, i-95% okanye i-97% ye-alumina iyacetyiswa. Ukuveliswa kwezinto zebhetri ye-lithium apho nokuba ukulandelela ukungcoliswa kwentsimbi kungamkelekanga, i-99% ibakala iyafumaneka.

Uluhlu lwemilo.Umgca wokusila opheleleyo udinga ngaphezu kwezitena zetrapezoid. Ikwafuna izitena ezixande kumacandelo athe tye, isiqingatha-izitena zendawo yomngxuma, izitena zeflake zamagophe aqinileyo, kunye neemilo ezikhethekileyo zokungena kunye neecones zokuphuma. I-Tecera ibonelela ngazo zonke, ukuze umthengi athenge ikiti epheleleyo kumthombo omnye.

Ubomi obude benkonzo ngokulahleka okuncinci kokunxiba.Umgangatho we-TL92S unelahleko yokunxiba ye-0.005% kuphela kwiiyure ezingama-24 - malunga nesiqingatha sokuphulukana nezitena ezisemgangathweni ezingama-92%. Eli xabiso lisezantsi lokunxiba livela kwi-microstructure exineneyo ephunyezwe ngolawulo oluchanekileyo lobungakanani besuntswana kunye nomjikelo olungisiweyo we-sintering. Kwilitye lokusila elilungisa intsimbi ekrwada, isitena esiqhelekileyo se-alumina sinokulahlekelwa yi-2-3 mm yobunzima kunyaka wokuqala. Isitena se-TL92S silahlekelwa sisiqingatha. Kumgodi obufudula ulungelelanisa indawo yawo yokusila rhoqo emva kweenyanga ezili-18, ukutshintshela kwi{14}izitena ezigugileyo kunokwandisa ixesha lokusila ukuya kwiinyanga ezingama-30–36. Ngamnye uthintelwe ukuxhonywa konga iintsuku zexesha lokuphumla, amashumi amawaka emsebenzini, kunye nexabiso lempahla yelineni ngokwalo. Kumthengi othengisiweyo, lo msantsa wokusebenza yindawo ecacileyo yokuthengisa kwibakala leprimiyamu.

I-Mechanical interlock ikhusela izitena ezikhululekile.Uninzi lwezitena zokusila zisebenzisa izitena ezixande ezibanjwe yi-epoxy yodwa. Kwimilili yebhola, i-lining ifumana ukungcangcazela rhoqo ukusuka kwiqokobhe elijikelezayo kunye nefuthe lokuwa kwemidiya yokusila. I-epoxy inokudinwa ngokuhamba kwexesha. Emva kokuba isitena esinye sikhululiwe, izitena ezikufutshane zilahlekelwa yinkxaso kwaye zilandele. Uyilo lwetrapezoid - lubanzi kwelinye icala, lucuthene kwelinye - ludala iweji yoomatshini. Isiphelo esibanzi sesitena esinye sitshixa kwicala elimxinwa lesinye. Nangona i-epoxy yobudala, izitena azikwazi ukutshintshela emacaleni okanye ziphakamise ngenxa yokuba zibanjelwe ngokwasemzimbeni. Kwisityalo esiye safumana izitena ezixekileyo zokukhupha iigrayiti zokukhupha okanye ukonakalisa iimpompo ezisezantsi, oku kugcinwa koomatshini ngumahluko phakathi kohlengahlengiso olucwangcisiweyo oluqikelelweyo kunye nolungiso olungxamisekileyo{9} lwephulo.

Ukungena kolwelo elinguziro kuphelisa umkhenkce-unyibiliko nomonakalo wekhemikhali.Ngokufunxwa kwamanzi ngaphantsi kwe-0.01%, isitena asiyongxaki. Akukho lulwelo oluludaka lunokungena kwi-ceramic. Kwisityalo sokulungiselela amalahle apho inkqubo yamanzi i-acidic, isitena esinamanzi sinokufunxa loo asidi kwaye sibe buthathaka ngaphakathi. Kwilitye lokusila elikwimozulu ebandayo, ukufuma okufunxayo bekuya kuba ngumkhenkce kuze kuqhekezwe isitena. Izitena ezixineneyo ze-alumina zisusa zombini iindlela zokungaphumeleli. Indawo yokusila esemantla eTshayina esebenzisa izitena zeTecera isebenze ubusika obuhlanu kungekho mkhenkce{7}ohlobene nokuqhekeka. Kumthengi, oko kuthetha imveliso esebenza ngokuthembekileyo nokuba injani na imozulu.

Amabanga aphezulu -ococeko anqanda ukungcoliseka kwemveliso.Ngomzimba we-ceramic kunye nokusila kwe-glaze, nokuba umkhondo wongcoliseko lwentsimbi unokutshintsha umbala wemveliso yokugqibela. Ukukhenkceza okumhlophe okujika kube ngwevu okanye kube mdaka ukusuka kumfanekiso wentsimbi kukwaliwa. I-TL95 kunye ne-TL97 amabakala asebenzisa i-alumina powder ngaphandle kwe-Fe₂O₃ ngaphantsi kwe-0.05% kunye ne-Na₂O ngaphantsi kwe-0.03%. Izitena ngokwazo zi-inert kwaye azifaki isinyithi kwizinto eziphathekayo. Kumvelisi wethayile zeceramic okanye umvelisi wemathiriyeli yelithium, obu busulungekileyo{8}}abuxoxiswana. Aba bathengi abanayo enye indlela ngaphandle kokusebenzisa{10}}iilayini ezicocekileyo zeceramic - kwaye baya kuhlawula ngokufanelekileyo.

Iindleko zokulungisa ezisezantsi ukusuka kukuvalwa okumbalwa.Indibaniselwano yelahleko ephantsi, ukuqhaga komatshini, kunye nokuzinza kweekhemikhali kuthetha ukuba i-lining ihlala ubomi bayo obupheleleyo boyilo ngaphandle{0}}kokusilela phakathi kwephulo. Indawo yokusila yesamente eBrazil isebenzisa izitena zeTecera TL92S yandisa isithuba sayo sokuhombisa ukusuka kwiinyanga ezili-18 ukuya ngaphezulu kweenyanga ezingama-42. Kumzi-mveliso osebenzisa i-1,000 kW ibhola lokusila iiyure ezingama-8,000 ngonyaka, ukuvalwa kwentsimbi nganye kubiza iintsuku zokulahleka kwemveliso, ukusebenza, kunye nemathiriyeli. Ukunciphisa inani leentsimbi ukusuka kwisithathu ukuya kwiminyaka emihlanu ukuya kwesinye kwiminyaka emihlanu kunciphisa ixabiso lilonke lokubuyisela ngesibini kwisithathu. Kumthengi othengisiweyo, esi sesona siphakamiso sexabiso esinyanzelisayo: imveliso exabisa ngaphezulu ngaphambili kodwa ixabisa kancinci kubomi bomatshini wokusila.

I-Tecera ibonelela ngee-ball liners kuwo onke amabanga e-TL (92, 92S, 95, 97), ezinoluhlu olupheleleyo lweemilo eziquka uxande, itrapezoid, isiqingatha{4}}isitena, i-flake, kunye nezitena zokungena/zokuphuma. Amaxabiso amaninzi ayafumaneka kubathengi beevenkile. Iisampuli zasimahla ziyafumaneka kuvavanyo olonakalisayo.

Ukucela ikowuti, nikezela ngedayamitha yelitye lokusila kunye nobude, iimilo zezitena ezifunekayo kunye nobukhulu, imathiriyeli ekufuneka icolwe, kunye noqikelelo lomthamo wonyaka. Ukufumana izixhobo zokusila ezipheleleyo, umzobo wokusila uluncedo.

Ixesha elikhokelayo lobungakanani bezitena eziqhelekileyo ziiveki ezi-2-3. Imilo eqhelekileyo ifuna iiveki ezi-4-6. Ukuthunyelwa ngenqanawe kumhlaba jikelele ngempahla yokuthumela ngaphandle{6}}kunikiwe. Ixesha lokuphendula kwizicelo zekowuti lidla ngokuba ziintsuku ezimbini zokusebenza.
