Omupiira Mill Liner

Layini y’ekyuma ekikuba omupiira ye lining etasobola kwambala-eteekebwa munda mu kyuma ky’omupiira okukuuma ekisusunku ky’ekyuma okuva ku kikolwa ky’okusena eky’ebyuma ebisena n’ekintu ekikolebwa. Layini zino zitera okukolebwa okuva mu matoffaali ga seramiki aga alumina aga density enkulu era nga zikozesebwa buli we kyetaagisa okusena obulungi - okusima, okulongoosa eby’obugagga eby’omu ttaka, okukola seminti, okukola seramiki, n’okukola amasannyalaze.

Enkizo enkulu eya ‘ceramic ball mill liner’ kwe kuwangaala. Ekyuma oba kapiira liner mu ball mill eyinza okumala emyezi 6–18, okusinziira ku nkola. Liner ya seramiki eya high-alumina, bw’eteekeddwa obulungi, esobola okumala emyaka 3–5 oba okusingawo. Enjawulo eyo evvuunulwa butereevu ku kuggalawo okutono olw’okusiba ebyuma, abakozi abatono abaddaabiriza, n’enteekateeka z’okufulumya eziteeberezebwa.

Kigonjoola kizibu ki? Mu kyuma ekikuba omupiira, lining etwala okukuba buli kiseera okuva mu kyuma oba ceramic grinding media. Ekiseera bwe kigenda kiyitawo, layini za standard zifuna enkola ezitali za kwambala, zaayatika oba zisumululwa. Layini bw’emala okulemererwa, ekisusunku ky’ekyuma kibikkulwa - era okuddaabiriza ekisusunku ekyambala kigula ssente nnyingi nnyo okusinga okukyusa layini. Layini ya seramiki ng’erina dizayini ekwatagana n’okufiirwa okwambala okutono emalawo emitendera gino egy’okulemererwa, n’ekuuma ekyuma nga kikola okutuusa ng’ekyuma ekiteredde kitegekeddwa.

Ku muguzi wa wholesale, kino kitegeeza okuwa eky’okugonjoola bakasitoma mu makolero g’eby’okusima eby’obugagga eby’omu ttaka, seminti, ne seramiki kye beetaaga mu butuufu - n’okuddamu okulagira okuva mu mirimu egyalabye enjawulo.

Ensonga ttaano ze zisalawo ebbanga lining y’ekyuma ky’omupiira ly’ewangaala.

Omuwendo gw’okwambala.Eno ye metric esinga obukulu. Ettoffaali eryambala mpola lijja kusigala mu buweereza okumala ebbanga. Tecera's TL92S grade efiirwa 0.005% zokka ku buzito bwayo mu ssaawa 24 mu mbeera z'okugezesa eza bulijjo - nga kitundu kya kufiirwa kwambala kwa standard 92% alumina bricks. Ekitundu ky’omuwendo gw’okwambala kitegeeza nga emirundi ebiri obulamu bw’okuweereza.

Dizayini ya Interlock.Dizayini y’amabaati aga trapezoid egazi ku nkomerero emu ate ku ndala nfunda. Bwe kiteekebwa ku mabbali, enkomerero engazi ey’ettoffaali erimu ekwatagana n’enkomerero enfunda ey’eddala. Ensigo eno ey’ebyuma ekuuma lining nga tefuddeeyo ne bwe kiba nti ekisiiga kya epoxy kituuka ekiseera ne kikaddiye. Mu kyuma ky’omupiira, layini efuna okukankana n’okukosebwa buli kiseera okuva mu mbeera z’emikutu gy’okusena - ezikooya epoxy okumala ekiseera. Ekyuma ekikwatagana (mechanical interlock) kiwa enkola y’okukuuma (backup retention system) amatoffaali aga bulijjo aga rectangular gye gabulamu.

Obuzito.Densite eya waggulu kitegeeza obuziba obutono, ekitegeeza nti okunyiga amazzi mutono n’okuziyiza okusingawo okulumbibwa eddagala okuva mu bikuta. Tecera’s TL95 ne TL97 grades zituuka ku bulk density waggulu wa 3.68 g/cm3 n’okunyiga amazzi wansi wa 0.01%. Obuziba buno obuli okumpi-ziro era buziyiza okwonooneka kw’obuziba-okusaanuuka mu byuma ebisangibwa mu mbeera ennyogovu.

Obulongoofu.Ebirimu Al2O3 ebingi kiwa amatoffaali amakalu, agagumira okwambala-. Ku kusenya kw’eby’obuggagga eby’omu ttaka okusinga obungi, ebitundu 92% bimala. Ku ceramic glaze grinding nga obucaafu bwandikosezza langi, 95% oba 97% alumina ye kirungi. Ku kukola ebintu bya bbaatule ya lithium nga wadde obucaafu bw’ekyuma ekitono tebukkirizibwa, 99% grade eriwo.

Enkula y’ebifo (shape range).Lining y’ekyuma enzijuvu yeetaaga ekisingawo ku mabaati aga trapezoid gokka. Era kyetaagisa amatoffaali aga nneekulungirivu ku bitundu ebigolokofu, amabaati ag’ekitundu-ag’ekitundu ky’ekinnya ky’omusajja, amatoffaali aga flake ku bikoona ebinywevu, n’ebifaananyi eby’enjawulo ku kkooni eziyingira n’ezifuluma. Tecera y’ezigaba zonna, kale kasitoma asobola okugula ekintu ekijjuvu okuva mu nsonda emu.

Obulamu obuwanvu obw’okuweereza okuyita mu kufiirwa okwambala okutono.Ekigero kya TL92S kirina okwe-okufiirwa okwambala kwa 0.005% zokka mu ssaawa 24 - nga kitundu kya kufiirwa kwambala kwa matoffaali ga alumina aga standard 92%. Omuwendo guno ogw’okwambala ogwa wansi guva mu microstructure enzito etuukiddwaako okuyita mu kufuga obunene bw’obutundutundu obutuufu n’enzirukanya y’okusiba erongooseddwa. Mu kyuma ky’omupiira ekirongoosa ekyuma ekikalu, ettoffaali lya alumina erya mutindo liyinza okufiirwa obuwanvu bwa mm 2–3 mu mwaka ogusooka. Ettoffaali lya TL92S lifiirwa ekitundu ekyo. Ku kirombe ekyali kiddamu okusiba ekyuma kyakyo buli luvannyuma lwa myezi 18, okukyusa okudda ku mabaati agayambala wansi-kisobola okwongera ku bbanga ly’okusiba okutuuka ku myezi 30–36. Buli emu eyeewaliddwa relining ewonya ennaku z’okuyimirira, enkumi n’enkumi z’abakozi, n’omuwendo gw’ebintu ebikozesebwa mu lining yennyini. Ku muguzi wa ‘wholesale’, ekituli kino mu nkola y’emirimu kye kifo ekitegeerekeka obulungi eky’okutunda ku mutindo gwa ‘premium’.

Mechanical interlock etangira amatoffaali agatambula.Ebisenge by’ekyuma ebisinga bikozesa amatoffaali aga nneekulungirivu agakwatibwa epoxy yokka. Mu kyuma ky’omupiira, lining efuna okukankana buli kiseera okuva mu kisusunku ekikyukakyuka n’okukubwa okuva mu mikutu gy’okusena egyagwa. Epoxy asobola okukoowa okumala ekiseera. Ettoffaali erimu bwe limala okusumululwa, amatoffaali agaliraanyewo gafiirwa obuwagizi ne gagoberera. Enteekateeka ya trapezoid - egazi ku nkomerero emu, enfunda ku ndala - ekola ekiwujjo eky’ebyuma. Enkomerero empanvu ey’ettoffaali erimu esibira ku nkomerero enfunda ey’eddala. Ne bwe kiba nti epoxy ekaddiye, amatoffaali tegasobola kukyuka ku mabbali oba okusituka okufuluma kubanga gasibira mu mubiri. Ku kyuma ekifunye amatoffaali agatali manywevu nga gazibikira ebisenge ebifulumya amazzi oba okwonoona ppampu eziri wansi, okusigala kuno okw’ebyuma y’enjawulo wakati w’okuteebereza okuteekebwateekebwa okuteekeddwateekeddwa n’okuddaabiriza okw’amangu wakati-kampeyini.

Okuyingira kw’amazzi nga ziro kumalawo okusaanuuka kw’okufuumuuka-okusaanuuka n’okwonooneka kw’eddagala.Nga okunyiga amazzi wansi wa 0.01%, ettoffaali mu butuufu teri-porous. Tewali mazzi ga slurry gayinza kuyingira mu ceramic. Mu kkolero ly’okuteekateeka amanda ng’amazzi g’enkola galimu asidi, ettoffaali eririmu obutuli lyandinyiga asidi oyo ne linafuwa okuva munda. Mu kyuma ekisangibwa mu mbeera ennyogovu, obunnyogovu obunywezeddwa bwandifuuse bbugumu ne bukutula ettoffaali. Amabaati ga alumina amanene gamalawo engeri zombi ez’okulemererwa. Ekyuma mu bukiikakkono bwa China ekikozesa amatoffaali ga Tecera kibadde kikola okumala ebbanga ttaano ery’obutiti nga tewali nnyatika yeekuusa ku kuziyira-. Ku muguzi wa ‘wholesale’, ekyo kitegeeza ekintu ekikola mu ngeri eyesigika awatali kulowooza ku mbeera y’obudde.

Ebika by’obulongoofu ebya waggulu-biziyiza obucaafu bw’ebintu.Ku mubiri gwa seramiki ne glaze grinding, ne trace iron obucaafu busobola okukyusa langi y’ekintu ekisembayo. Glaze enjeru efuuka enzirugavu oba kitaka okuva ku pickup y’ekyuma eba reject. Ebika bya TL95 ne TL97 bikozesa butto wa alumina ayingizibwa mu ggwanga nga Fe2O3 wansi wa 0.05% ate Na2O wansi wa 0.03%. Amabaati gennyini tegakola era tegakulukuta byuma mu kintu ekiseerwa. Ku omukozi wa tile za seramiki oba omukozi w’ebintu bya bbaatule ya lithium, obulongoofu buno tebuyinza kuteesebwako. Bakasitoma bano tebalina ngeri ndala yonna okuggyako okukozesa high-purity ceramic linings - era bajja kusasula okusinziira ku ekyo.

Okukendeeza ku ssente z’okuddaabiriza okuva ku kuggala okutono.Okugatta okufiirwa okwambala okutono, okusiba ebyuma, n’okunyweza eddagala kitegeeza nti lining ewangaala obulamu bwayo obujjuvu obwa dizayini awatali kulemererwa kwa makkati-kampeyini. Ekyuma kya seminti mu Brazil nga kikozesa amatoffaali ga Tecera TL92S kyayongera ku bbanga lyakyo ery’okusiba okuva ku myezi 18 okutuuka ku myezi egisukka mu 42. Ku kyuma ekiddukanya ekyuma ekikuba emipiira ekya kW 1,000 essaawa 8,000 buli mwaka, buli kuggalawo okusiba amayinja kimalawo ennaku z’okufiirwa okufulumya, abakozi, n’ebikozesebwa. Okukendeeza ku muwendo gw’okusiba okuva ku ssatu buli myaka etaano okutuuka ku kimu ku buli myaka etaano kisala ku muwendo gwonna ogw’okusiba ebitundu bibiri-ku bisatu. Ku muguzi wa wholesale, kino kye kiteeso ky’omuwendo ekisinga okusikiriza: ekintu ekigula ssente ennyingi mu maaso naye nga kigula ssente ntono mu bulamu bw’ekyuma.

Tecera egaba liners z’ekyuma ekikuba emipiira mu ddaala zonna eza TL (92, 92S, 95, 97), nga zirina enkula ezijjuvu omuli rectangle, trapezoid, half-brick, flake, ne custom inlet/outlet bricks. Emiwendo egy’amaanyi gibeerawo eri abaguzi ba ‘wholesale’. Sampuli za bwereere ziriwo okukeberebwa mu ngeri ey’okusaanyaawo.

Okusaba quote, waayo dayamita n’obuwanvu bw’ekyuma, enkula n’obuwanvu bw’amabaati ebyetaagisa, ebintu ebirina okusiigibwa, n’obunene obubalirirwamu buli mwaka. Ku bikozesebwa mu kukola ‘mill lining kits’ ebijjuvu, okukuba ekifaananyi ky’ekyuma kiyamba.

Obudde bw’okukulembera ku sayizi z’amabaati eza bulijjo buba wiiki 2–3. Ebifaananyi eby’enjawulo byetaaga wiiki 4–6. Okusindika mu nsi yonna n'okupakinga okw'omutindo gw'okutunda ebweru-kuweebwa. Obudde bw’okuddamu okusaba quote butera kuba bwa nnaku bbiri ez’omulimu.
