Ii-TIC Insert Crusher Liners zeMigodi yeGolide yaseNtshona Afrika: Izinto ezi-5 ezichaphazela ubomi benkonzo kwiimeko zokurhawuzelelwa okuphezulu

Emva kweminyaka elishumi ndinceda imisebenzi yokwemba igolide eNtshona Afrika ukuba yandise ubomi bayo bokusebenza kwi-crusher liner, ndingatsho oku ngokuqinisekileyo: Izinto ezintlanu ezijongwa kakhulu yimigodi zezona zinto zimisela ukuba i-TIC insert liner ihlala iinyanga ezi-4 okanye iinyanga ezili-14 phantsi kokutya okufanayo okune-quartz. Umahluko asikokuba ixabiso le-liner liner lingakanani. Asikuko ukuba igama lebhrendi lifakwe ngasemva. Ingaba iqela lobunjineli lomgodi liyaqonda na ukuba ukusebenza kwe-TIC insert yingxaki yeenkqubo?, asiyongxaki yokuthenga izinto.

Ndikhe ndahamba kwiindawo zokuvalwa eGhana apho abaqhubi bandixelele ukuba "ezi zinto zifakiweyo azisebenzi," kodwa ndafumanisa ukuba ezi zinto zifakwe kwindawo engafanelekanga yokuguguleka ngenxa yendlela ethile yokutyumza yegumbi le-crusher. Ndizijongile iifoto zokusilela ezivela eBurkina Faso apho unyango lobushushu olungachazwanga kakuhle ludale umaleko wotshintsho olubuthathaka ongazange usebenze kwiiyure ezingama-72 emva kokufakwaIxesha ngalinye, unobangela wawulandelwa kwenye okanye ngaphezulu kwezi zinto zintlanu endizakuchaza kweli nqaku. Iindaba ezimnandi: yonke into kwezi zinto inokulawulwa — ukuba uyazi ukuba ungazikhangela.

Kule khokelo, ndiza kukubonisa yonke into ngokusekelwe kwidatha yokwenyani, iziseko zesinyithi, kunye nezifundo endizifundileyo ekuxhaseni imigodi kulo lonke elaseGhana, eMali, eBurkina Faso, naseCôte d'Ivoire. Nokuba usebenzisa i-gyratory ephambili kwimigodi yegolide elukhuni okanye i-crusher yesibini ecubungula i-ore ye-quartz-gold erhabaxa, ezi zinto zintlanu ziya kumisela ubomi bokwenyani benkonzo ye-liner yakho.

1. Ukuchazwa kwezinto ezisetyenziswa kwi-feed: Umxholo we-silica nguMbulali woBomi obuThulileyo

Eyona nto iphambili enokuxelwa kwangaphambili kwizinga lokuguguleka kwe-TIC insert crusher liner kwimigodi yegolide yaseNtshona Afrika ngumxholo we-silica (SiO₂) wezinto zokutya. Ngokwamava am okujonga idatha yokuguguleka kwiindawo ezingaphezu kwama-30 zemigodi kulo mmandla, ukunyuka ngamanqaku ama-5 ekhulwini kumxholo we-silica ongaphezulu kwama-55% kunciphisa ubomi benkonzo ye-liner malunga ne-18–22%, zonke ezinye iimeko zithathwa zilingana.

Oku akusiyo into ebonwayo ngokwethiyori. Ngenxa yokuba iintlobo zamatye aphethe igolide kwiCraton yaseNtshona Afrika — i-quartzite, i-silicified schist, kunye ne-banded iron formation (BIF) — zihlala ziqulathe umxholo we-silica ophakathi kwama-62% ukuya kuma-78%., umthwalo orhabaxa kwii-crusher liners kule ndawo wahlukile ngokupheleleyo kulowo ubuya kudibana nawo kumsebenzi we-limestone okanye we-copper-porphyry.

Indlela yokusebenza ilula kodwa idla ngokungaqondwa kakuhle. Ii-TIC inserts zifikelela ekugugeni kwazo ngokusebenzisa uyilo lobunzima obuphindwe kabini: iphini ye-titanium carbide inobunzima obuncinci obumalunga ne-2,800–3,200 HV, ngelixa i-matrix yentsimbi ye-manganese ejikelezileyo idla ngokuba phakathi kwe-450–550 HB emva kokuqina komsebenzi.Amasuntswana e-quartz aqinileyo (ubulukhuni be-Mohs 7, malunga ne-1,100–1,300 HV) asusa ngokulula intsimbi ye-manganese kodwa akanakukrwela ngokunentsingiselo iiphini ze-TIC. Isiphumo kukuguguleka okwahlukileyo: I-matrix ye-manganese iyaphela kuqala, iveza kancinci kancinci umphezulu we-TIC pin, othi emva koko ube nesabelo esikhulayo somthwalo orhabaxa..

Nangona kunjalo - kwaye kulapho imigodi emininzi iphazama khona - xa umxholo we-silica udlula malunga ne-70%, kwane-manganese matrix ephakathi kwezinto ezifakiweyo iyaguga ngokukhawuleza kangangokuba ii-TIC pins zilahlekelwa yinkxaso yazo yoomatshini.. Ezi pini ziba "ziziqithi" ezimi ziqhayisa ngomphezulu wentsimbi obuyela umva ngokukhawuleza, kwaye amandla okubetha aze aziqhekeze engcanjini. Ndiyibonile le ndlela yokusilela kwimigodi yegolide icubungula ukwakheka kwelitye eliluhlaza laseBirimian elinolwe-silicic kakhulu kumzantsi weMali, apho ii-liners ebezifanele ukuba zihlale iiyure ezingama-2,800 zokusebenza zasilela kwiiyure ezili-1,200 kuba i-matrix yaphela ngokukhawuleza.

💡 Ingcaciso ephambili evela kumava am entsimini: Ngaphambi kokuba ndi-odole nayiphi na i-TIC insert liner yomgodi wegolide eNtshona Afrika, ndihlala ndicela ingxelo epheleleyo ye-feed mineralogy ethatha ubuncinane iinyanga ezintandathu zedatha yemvelisoUmxholo we-silica uyahluka ngokwexesha lonyaka — i-ore yexesha lemvula idla ngokuthwala udongwe oluninzi kunye ne-silica encinci ekhululekileyo, ngelixa i-ore yexesha elomileyo idla ngokuba "icocekile" kwaye irhabaxa kakhulu. I-liner specification eyenzelwe umxholo oqhelekileyo we-silica iya kusilela kwangethuba ngexesha lemvula. Ndicebisa ukuyila i-ore yexesha elomileyo. umxholo ophezulu we-silica olindelekileyo, hayi umndilili.

Oko Kumelwe Kulinganiswe (Ngaphaya kweSiO₂ eSisiseko)

• Ukusasazwa kobungakanani bengqolowa yeQuartz: I-quartz ecolekileyo (≥0.5 mm) ibangela ukukrweleka kwemizimba emithathu phakathi kweendawo ezityumkileyo, nto leyo ekhawulezisa ukuguguleka nge-15–25% xa kuthelekiswa ne-quartz ecolekileyo. Ndihlala ndicela imigodi ukuba ifake uhlalutyo lwe-petrographic thin-section lwe-feed ore yazo.
• Umxholo wobumanzi: Ukufuma kokutya okungaphezulu kwe-8% kudala intlama efana nodaka kunciphisa uqhagamshelwano oluthe ngqo phakathi kwe-particle-to-liner, eneneni kunciphisa ukuguguleka okurhabaxa — kodwa kwandisa umngcipheko wokupakisha kunye nomthwalo ongalinganiyo we-liner. Iimigodi ezininzi endisebenza nazo kwixesha lemvula laseGhana zigcina ngabom ukufuma kokutya okuyi-6–8% njengecebo lokulawula ukuguguleka.
• Izinto ezingcolisayo zeminerali eqinileyo: Ngaphaya kwe-silica, qaphela i-corundum (Al₂O₃, Mohs 9) kunye nemithambo ye-pegmatite ene-topaz. Nokuba zimbalwa kangakanani ezi minerali ziqinileyo zinokwenza ukukrwela imiphezulu ye-TIC, into engenakukwazi ukuyenza i-silica, ngokusisiseko itshintsha indlela yokuguguleka ukusuka ekukrazuleni kwemizimba emibini ukuya ekucutheni okuncinci.

2. Uyilo lwe-TIC Insert kunye nePateni yokubeka: I-Overlooked Engineering Variable

Ndihlolisise amakhulu ee-TIC insert liners ezigugileyo ezivela kwimigodi yaseNtshona Afrika, kwaye eyona nto ixhaphakileyo yokusilela kwangethuba endidibana nayo yile ayilomgangatho wezinto ezibonakalayo — yijiyometri yokubekwa kwentoIpateni, isithuba, ubungakanani, kunye nolwalathiso lwee-TIC inserts ngaphakathi kwe-matrix yentsimbi ye-manganese zimisela ngokuthe ngqo ukuba i-liner inxiba ngokufanayo okanye iphuhlisa iindawo zokusilela zasekuhlaleni.

Ngenxa yokuba ii-TIC inserts zinzima ngokuphindwe ka-5–8 kune-matrix yentsimbi ye-manganese ejikelezileyo, umahluko wesantya sokuguguleka phakathi kwezi zinto zimbini udala iprofayili yomphezulu oguqukayo ngexesha lokusebenza. Ukuba izinto ezifakiweyo zibekwe mgama omkhulu kakhulu (umgama ukusuka embindini ukuya embindini ≥ 2.5× ububanzi bokufaka), intsimbi ye-manganese ephakathi kwazo iyaguguleka iye kwimijelo enzulu ngaphambi kokuba izinto ezifakiweyo ziguguleke ngokwaneleyo, kubangela ukuba izikhonkwane zilahlekelwe yinkxaso esecaleni kwaye zaphuke xa zitshayiswaUkuba izinto ezifakwayo zixinene kakhulu (umgama ukusuka embindini ukuya embindini ≤ 1.2 × ububanzi bokufaka), umthamo wentsimbi ye-manganese esebenzayo awanelanga ukufunxa amandla ombane, kwaye wonke umphezulu odibeneyo uba buthathaka.

Umgaqo-nkqubo weMephu yeNdawo yokuNxiba

Ayizizo zonke iindawo ze-crusher liner eziguga ngesantya esifanayo. Kwi-ore ye-quartz-gold esetyenziswa kwi-cone crusher yaseNtshona Afrika, ndiqaphele rhoqo ukuba isithathu esisezantsi se-mantle kunye nesiqingatha esiphezulu se-bowl liner sifumana ama-60-70% okuguguleka okupheleleyo. Ukubeka uxinano olufanayo lwe-TIC insert kuyo yonke i-liner face waste inserts kwiindawo eziphantsi kokuguga kwaye kushiya iindawo eziphantsi kokuguga zingakhuselekanga ngokwaneleyo.

Indlela echanekileyo — endiyigxininisayo kuyo yonke inqanawa ye-STK Mining esiyinikezela eNtshona Afrika — yile imephu yendawo yokunxiba:

1. Indawo 1 (Impahla Enxibe Kakhulu — Phezulu kweBhowule / Ezantsi kweMantle): Ubuninzi bokufakwa kwe-insert, ipateni ye-hexagonal, isithuba se-1.6 × insert Ø. Kulapho igumbi lokutyumza lifumana amandla aphezulu oqhagamshelwano axinzelelekileyo natyibilikayo.
2. Indawo yesi-2 (Igumbi eliPhakathi — Igumbi eliPhakathi): Uxinano oluphakathi lokufaka, ipateni yegridi edibeneyo, isithuba se-2.0× sokufaka i-Ø. Le ndawo ibona ukurhawuzelelwa okuphakathi kodwa kufuneka ikwajongane nokudluliselwa kwamandla ombane.
3. Indawo 3 (Imilebe Enganxitywanga Kakhulu — Ukuvula/Ukukhupha Impumlo): Izifakelo ezincinci okanye azikho. Ezi ndawo zihlala zifumana impembelelo, azinakrwelo, kwaye izifakelo ezingaphezulu apha zonyusa ubukrwelo ngaphandle kwenzuzo.

Kwenye imigodi yegolide emantla eBurkina Faso, ndafumanisa ukuba umthengisi wabo wangaphambili wayesebenzisa isithuba sokufakwa esifanayo kuyo yonke i-mantle — kwaye i-inserts ezisezantsi kwesithathu zazisilela kwi-3x izinga le-inserts ezikwindawo ephezuluNgokuyila ngokutsha ngendlela yethu yokwahlulahlula iindawo, sandise ubomi be-liner iyonke ngama-41% ngaphandle kokutshintsha isiseko sesinyithi kwaphela. Ukunyuka kweendleko bekumalunga ne-8% (izinto ezingaphezulu ezifakwe kwindawo egudileyo, zimbalwa kwindawo egudileyo), kwaye i-ROI evela kwixesha lokungasebenzi elincitshisiweyo lodwa ihlawulele ukuphuculwa kwiinyanga ezintathu.

3. Umgangatho woNyango loBushushu kunye ne-TIC-to-Matrix Bonding Interface

Le yeyona nto indigcina ndiphaphile ebusuku — kwaye ifanele ikugcine uphaphile nawe ukuba unoxanduva lokuthenga i-crusher liner kwimigodi yegolide eNtshona Afrika. Unxibelelwano lokubopha phakathi kwe-TIC insert kunye ne-manganese steel matrix yindawo yotshintsho lwe-metallurgical edla ngokuba yi-50–200 microns ubukhulu, kwaye umgangatho wayo awubonakali kwaphela emehlweni.

Xa i-bonding interface yenziwe ngokufanelekileyo — ngokusebenzisa isisombululo esilawulwayo esifakwe kwi-1,050–1,100°C kulandele ukucima amanzi — i-titanium carbide isasazeka ngokuyinxenye kwintsimbi ye-austenitic manganese, idale i- ujongano olunemigangatho enobunzima obunciphayo ukusuka kwi ~2,800 HV (i-TiC emsulwa) ukuya kwi ~200 HV (intsimbi ye-Mn etyhidiweyo)Le gradient isasaza uxinzelelo kulo lonke i-interface zone endaweni yokuyigxininisa kumda obukhali.

Nangona kunjalo, xa unyango lobushushu lukhawuleziswa okanye lulawulwa ngendlela engafanelekanga, kunokwakheka izakhiwo ezincinci ezininzi ezinokusilela endaweni yoko:

• Ukuna kwekhabhoyidi kwimida yeenkozo: Ukuba ukupholisa kucotha kakhulu kuluhlu lwe-800–500°C, i-chromium kunye ne-molybdenum carbides ziyawa kwimida ye-austenite grain, nto leyo edala iinethiwekhi ezibuthathaka eziqhekekayo phantsi komjikelo wokuqala omkhulu wempembelelo. Ndiyifumene le ndlela yokusilela kwii-liners ezibonise ukuhlambulula ngaphakathi kweeyure ezingama-48–72 yokufakelwa — kusekutsha kakhulu ukuba ukuguguleka okurhabaxa kube yimbangela.
• Ukucoca isisombululo esingaphelelanga: Ukuba ubushushu obubambekayo kwi-1,050–1,100°C bugcinwa ngaphantsi kweeyure ezi-2 kwi-25 mm yobukhulu becandelo, ii-carbides azinyibiliki ngokupheleleyo kwi-austenite matrix. Isiphumo kukuba "Iziqithi" ze-carbide ezisele ezisebenza njengeendawo zokuqalisa ii-crack phantsi komthwalo onzima.
• Ukususwa kwekhabhoni ngokugqithisileyo kwindawo yokujonga i-insert-matrix: Ngexesha lokuvezwa ixesha elide kwi-atmospheres yesithando ngaphambi kokuthulula, umphezulu we-TIC insert unokulahlekelwa yi-carbon, okwenza umaleko othambileyo we-TiO₂-rich otyebileyo kuthintela ukubopha okufanelekileyo kwesinyithi ngentsimbi yemanganese. Oku kuvelisa into endiyibiza ngokuba yi-"mechanical-only" bond — i-insert ibanjwe ngokoqobo kwintsimbi kodwa ayinayo i-atomic-level fusion nayo.

💡 Oko Ndikufunayo Kwi-Foundry Yethu: Kwibhetshi nganye yee-TIC insert liners ezithunyelwa eNtshona Afrika, ndifuna: (1) iitshathi zobushushu ezithatha isisombululo ezinee-data points ezi-6 ze-thermocouple ubuncinane ngetshaja nganye yonyango lobushushu, (2) imephu yobunzima kuyo yonke i-interface ye-insert-matrix (ubuncinci ii-indentations ezi-5 ukusuka kwiziko lokufaka ukuya kwi-matrix kwi-intervals ye-1 mm), kunye (3) ukuhlolwa kwedayi yokungena kwe-insert periphery emva kokucima ukuze kubonwe naziphi na ii-micro-cracks ezenziwe ngexesha loxinzelelo lobushushu. Ukuba umthengisi akanakukwazi ukubonelela ngazo zontathu, andiyi kuzithemba ezo liner kwi-primary crusher yaseNtshona Afrika.

Indlela Yokuqinisekisa Umgangatho Wonyango Lobushushu Ngaphambi Kokufakwa

Iindawo zemigodi zaseNtshona Afrika azinazo iilabhoratri zesinyithi kwindawo leyo. Kodwa kukho iitshekhi ezintathu ezisebenzayo endizicebisayo:

1. Uvavanyo lokuqina kumphezulu we-liner: Sebenzisa isixhobo sokuvavanya ubunzima beLeeb esiphathwayo (i-Equotip okanye esilinganayo). I-matrix yentsimbi ye-manganese phakathi kwezinto ezifakiweyo kufuneka ifunde i-200–240 HB kwimeko yokuziswa kwayo. Izifundo ezingaphantsi kwe-180 HB zibonisa ukutsalwa kwesisombululo okungaphelelanga; izifundo ezingaphezulu kwe-260 HB zibonisa ukuna kwe-carbide engafunekiyo. Vavanya ubuncinane iindawo ezi-6 kwi-liner nganye uze uyilahle ukuba ukuphambuka okuqhelekileyo kudlula i-15 HB.
2. Ukuhlolwa kokugqobhoza kwedayi ejikeleze imiphetho yokufaka: Futha idayi ebomvu eqhelekileyo engenela malunga ne-20% yee-TIC insert perimeters (ekhethwe ngokungacwangciswanga), coca, faka umphuhlisi, kwaye uhlole phantsi kokukhanya okumhlophe. Nasiphi na isibonakaliso esithe tyaba esidlula ngaphezulu kwe-3 mm ukusuka kumphetho wokufaka asifanelekanga — ibonisa umfantu oya kusasazeka phantsi kwemithwalo yempembelelo ye-crusher.
3. Ikhuphoni enqamlezileyo evela kubushushu obufanayo: Cela ukuba isiseko sibe nekhuphoni yovavanyo lokuzincama ephoswe kubushushu obufanayo nee-liner zemveliso. Sika kwaye upolisha ikhuphoni ukuze ujonge ujongano lwe-insert-matrix kwi-magnification ye-50×. Ujongano olubotshelelwe ngokufanelekileyo kufuneka lubonise akukho msantsa ubonakalayo, akukho mingxunya, kunye nendawo yotshintsho eqhubekayo.

4. Iiparameters zokusebenza kweCrusher: Indlela iCSS, iSpeed, kunye noLawulo lweFeed ezibumba ngayo ubomi benkonzo yeLiner

Kwane-TIC insert liner eyenziwe kakuhle iya kusilela ngaphambi kwexesha ukuba i-crusher isebenza ngaphandle kwemilinganiselo yayo yoyilo. Ndiyibonile le ndlela ngokuphindaphindiweyo kwimigodi yegolide eNtshona Afrika apho uxinzelelo lwemveliso luqhuba abaqhubi ukuba baqinise i-closed-side setting (CSS) ngaphaya kwemfuneko okanye basebenzise i-crusher kwi-output ephezulu nokuba iimeko zokufunxa zinjani na.

Useto lweCandelo eliValiweyo (CSS)

I-CSS imisela ixesha lokuhlala kwamasuntswana kwigumbi lokutyumza kunye namandla oxinzelelo oluphezulu kumphezulu we-liner. Kuba ukuqinisa i-CSS nge-5 mm kuphela (ngaphantsi koluhlu olucetyiswa yi-OEM) kunokunyusa uxinzelelo lwe-liner olubekwe kwindawo ethile nge-25–40%, le parameter inefuthe elikhulu kakhulu kwindlela yokuziphatha kwe-TIC insert liner.

Indlela ethile yokusilela yile: xa i-CSS iqinile kakhulu, amasuntswana ayanyanzeleka ukuba adlule kumsantsa omncinci ekupheleni kokukhutshwa, ukudala uxinzelelo oluphezulu phakathi kwamasuntswana kunye noqhagamshelwano oluthe tyibilikayo phakathi kwamasuntswana e-ore kunye nomphezulu we-liner. Kwi-TIC insert liners, oku kwenza izinto ezimbini. Okokuqala, kukhawulezisa ukuguguleka kwe-matrix, okuthi - njengoko ndichazile kwiFactor 2 - kushiye i-inserts ingaxhaswa. Okwesibini, kwandisa ubuninzi kunye nobunzima be "faka impembelelo yomda", apho amasuntswana e-quartz aqinileyo abetha umda ophakathi kwe-TIC pin kunye ne-manganese steel matrix, esebenzisa ukungalingani kobunzima ukuqala ii-micro-cracks.

Umthetho wam obalulekileyo nge-ore ye-quartz-gold yaseNtshona Afrika: ungaze usebenze ngaphantsi kwe-90% ye-CSS encinci ecetyiswa yi-OEM xa usebenzisa ii-TIC insert liners. Inzuzo ye-marginal throughput evela kwisetingi eqinileyo (ngesiqhelo yi-3–5%) isuswa kukukhawuleziswa kokuguguleka kwe-liner okungaqhelekanga (ukuncipha kwe-15–25% kubomi benkonzo ngokusekelwe kwidatha endiyiqokelele kwiindawo ezi-8 zemigodi).

Isantya seCrusher (RPM)

Isantya sokujikeleza kwe-crusher sichaphazela inani leziganeko zokutyumza ngexesha ngalinye kunye namandla e-kinetic empembelelo nganye. Kuba ii-TIC inserts zibuthathaka ngakumbi kune-manganese steel matrix, ukusebenza ngesantya esiphezulu konakalisa kakhulu izinto ezifakwayo ngokuqhekeka kokudinwa.

Kwi-cone crusher esebenza nge-hard rock ngesantya esingama-95–105%, i-TIC insert nganye ifumana amava amalunga ne-1.5% Imijikelo yempembelelo yezigidi ezili-1.2–1.5 ngeeyure zokusebenza ezili-1,000. Le yindlela yokudinwa eyenzeka rhoqo apho nokuba uxinzelelo oluncinci — njengokungaqhubeki kwejiyometri kumda we-insert-matrix — kunokuqalisa nokusasaza iintanda. Ndifumanise ukuba ukunciphisa isantya se-crusher nge-7–10% kuphela (ukuhlala ngaphakathi koluhlu olwamkelekileyo lwe-OEM) kunokwandisa ubomi be-TIC insert liner nge-12–18% kwizicelo ze-hard-rock zaseNtshona Afrika, kuba itshintsha usasazo lwamandla empembelelo ukusuka kwimiphetho ye-insert ephezulu ukuya kwi-ductile matrix engaphezulu.

Ukondla kunye nokusasazwa kokutya kweChoke

Mhlawumbi le yeyona nto ingabonakaliyo kwezobugcisa, kodwa ngokwamava am, ibangela ukuba kubekho ukunxitywa okungalinganiyo kwee-liner. Kuba ukutya okukrwitshwayo kuqinisekisa ukuba igumbi lokutyumza lihlala lizele zizinto, amasuntswana okutya enza "umbhede wee-particle" okhuselayo okhusela impembelelo yamatye angenayo kumphezulu we-liner. Xa igumbi lihamba lingenanto kancinci — okuqhelekileyo ngexesha lokutshintsha kwelori kwiindawo zemigodi ezikude zaseNtshona Afrika — amatye angenayo abetha ngqo kwi-liner, edala iindawo zempembelelo zasekuhlaleni ezonakalisa ngokukhethekileyo i-TIC inserts.

Ndicebisa ukuba imigodi yaseNtshona Afrika esebenzisa ii-TIC insert liners zifake izinzwa ezikumgangatho ophezulu kwi-crusher feed hopper ene-interlock ezenzekelayo oko kuyayicothisa i-crusher ukuba inqanaba lokutya lehla ngaphantsi kwe-70% ye-full. Olu longezo lulula - olubiza mhlawumbi i-$5,000–$8,000 kwizixhobo - luncede imigodi endisebenza nayo ukuba isuse ipateni yokuguguleka "ye-hungry crusher" eyayitshabalalisa amacandelo e-liner kwiinyanga ezi-2-3.

5. Iinkqubo zoLondolozo kunye nokuJonga ukuNxiba: Ukubamba iingxaki ngaphambi kokuba zisilele

Umahluko phakathi kwe-liner etshintshwa ngexesha elifanelekileyo kunye ne-liner engasebenzi kakuhle ngokungalindelekanga udla ngokuxhomekeka kumgangatho - kunye nokuphindaphindwa - kokujonga ukuguguleka. Imigodi yegolide eNtshona Afrika isebenza kwiindawo ezinzima kakhulu apho iifestile zokulungisa ezicwangcisiweyo zixabisekile kwaye ixesha lokungasebenzi elingacwangciswanga linokudla i-$50,000–$200,000 ngeyure. Kule meko, ukujonga ukunxiba kwangaphambili akuyondleko engaphezulu - yinshurensi yokulahlekelwa yimveliso enkulu.

Iprotokholi yokulinganisa ukunxiba kweeyure ezili-100

Kwimigodi apho ndibone khona ukusebenza kakuhle kwe-TIC insert liner, iqela lokulungisa lilinganisa ukuguguleka kwe-liner. qho emva kweeyure ezili-100 zokusebenza, hayi yonke i-500 okanye i-1,000 njengoko kuqhelekile. Isizathu silula: kuba ii-TIC insert liners ziguga ngendlela engeyiyo i-linear — ukuguguleka kokuqala kancinci njengoko i-manganese matrix isebenza nzima, kulandele ukuguguleka okukhawulezileyo xa ii-inserts ziqala ukulahlekelwa yinkxaso — ixesha lokulinganisa leeyure ezingama-500 linzima kakhulu ukuba lifikelele kwinqanaba lokutshintsha.

Qaphela: La manani asekelwe kwidatha yam yasentsimini evela kwii-cone crushers ezicubungula i-65–72% ye-silica quartz-gold ore kwi-85–95% ye-CSS eqhelekileyo. Amanqanaba akho okuguguleka aya kwahluka ngokweempawu ze-ore kunye neeparamitha zokusebenza.

Iprofayili yeLaser vs. Ukulinganisa ngesandla

Ndicebisa kakhulu ukuba imigodi yegolide eNtshona Afrika ityale imali kwi ukuskena iprofayili yelaser yee-crusher liners. Iskena selaser esiphathwa ngesandla (esifana nesaseLeica okanye iFARO) sinokubamba iprofayili epheleleyo yokuguguleka kwe-3D ngaphantsi kwemizuzu eli-10, xa kuthelekiswa nemizuzu engama-45-60 efunekayo yokulinganisa i-caliper ngesandla kwiindawo ezininzi zokubhekisa. Okubaluleke ngakumbi, kuba iskena selaser sibamba umphezulu wonke we-liner, sibonisa iipateni zokunxiba ezikufutshane — ezifana nokuguguleka "koncumo" kwindawo yokuvula ukutya okanye ukuguguleka "kwebhafu" kwigumbi eliphakathi — oko kulinganiswa kwamanqaku ngesandla kudla ngokungafumaneki rhoqo.

Kwenye imigodi eGhana apho sasebenzisa khona i-laser profiles kwi-100-hour intervals, safumanisa ukuba ipatheni yokuguguleka engalinganiyo yayikhula kwicala lasekhohlo le-mantle. umthuthi olungelelanisiweyo kakuhle utyisa isityumzi i-15° ngaphandle kweziko, ukugxininisa ukuguguleka kwikota enye. Ngaphandle kweprofayili yelaser, le patheni ibingayi kuhlala ingabonakali de i-liner yonakale ngaphambi kwexesha. Ukulungiswa — ukulungelelanisa kwakhona i-feed conveyor — kubiza ngaphantsi kwe-$2,000 kwaye kwandisa ubomi benkonzo ye-liner ngama-22%.

Uhlalutyo lokugcinwa kweerekhodi kunye neempawu

Ii-liners ozitshintshayo namhlanje kufuneka zixelele ii-liners ozi-odolayo ngomso. Ndigxininisa ukuba yonke imigodi endisebenza ngayo igcine umkhondo olula wespredishithi ubuncinane: (1) umhla wokufakwa kunye nobukhulu bokuqala be-liner kwiindawo ezi-6 zokubhekisa, (2) ukulinganiswa kokuguguleka kwisithuba ngasinye seeyure ezili-100, (3) iiyure zokusebenza kwe-crusher kunye nesantya esiphakathi sokuphuma kwemveliso ngexesha lesithuba ngasinye, (4) naziphi na iingxaki zokusebenza (iziganeko zentsimbi ye-tramp, ukuphazamiseka kokutya, utshintsho lwesantya), kunye (5) imeko yokugqibela ye-liner xa isuswa kunye nemifanekiso yomphezulu ogugulekileyo.

Le seti yedatha, eqokelelwe ngaphezulu kwe-3-4 liner change-outs, idala ijika lokuguguleka elikhethekileyo kwindawo ethile eliqikelela ngakumbi kunalo naliphi na iphepha ledatha lomenzi oqhelekileyoNdisebenzisa le datha ukuphucula iipateni zokubeka i-TIC insert kwimigodi nganye ethile, ngokuqhelekileyo ndiphucula ubomi be-liner nge-10–15% eyongezelelweyo kwi-oda yesibini neyesithathu.

Imibuzo Ebuzwa Rhoqo Malunga nee-TIC Insert Crusher Liners kwiMigodi yeGolide yaseNtshona Afrika

Q: Zihlala ixesha elingakanani ii-TIC insert liners xa zithelekiswa nee-standard manganese liners kwigolide yaseNtshona Afrika?

Ngokusekelwe kwidatha yam yasentsimini evela eGhana, eMali, eBurkina Faso, naseCôte d'Ivoire, ii-TIC insert liners zibonelela ngobomi benkonzo obuyi-2× ukuya kwi-4× yee-standard manganese liners (amanqanaba e-Mn14Cr2 okanye i-Mn18Cr2) xa izinto ezintlanu ezikweli nqaku zilawulwa ngokufanelekileyo. Isiphindaphindi sokwenyani sixhomekeke kakhulu kumxholo we-silica: kwi-55–65% ye-SiO₂, uluhlu lwe-3–4× lunokufikeleleka; kwi-70%+ ye-SiO₂, uluhlu luncipha luye kwi-2–2.5×. Utshintsho oluphambili kukuba ingaba ipateni yokubeka i-TIC insert ilungiselelwe loo mntu uthile - iipateni zokufaka eziqhelekileyo "ezingekho eshelufini" zihlala ziphumelela kuphela kwi-1.5–2×.

Q: Ngaba ii-TIC insert liners zixabisa ixabiso eliphezulu kwi-300 tph gold operation?

Ewe — kodwa kuphela ukuba ubala ixabiso lilonke lobunini (i-TCO), hayi ixabiso lokuthenga. Kwi-300 tph yegolide yaseNtshona Afrika eqhelekileyo eqhuba iiyure ezingama-6,000 ngonyaka, ii-manganese liners eziqhelekileyo zinokubiza i-$8,000–$12,000 ngeseti nganye kwaye zihlale iiyure ezili-1,200–1,600 (ezifuna ukutshintsha oku-4–5 ngonyaka). Ii-TIC insert liners zinokubiza i-$18,000–$26,000 ngeseti nganye kodwa zihlale iiyure ezingama-2,800–4,800 (ezifuna ukutshintsha oku-1–2 ngonyaka). Xa ujonga iiyure ezi-8–12 zexesha lokungasebenzi ngetshintshi nganye kwi-$50,000–$200,000/iyure kwimveliso elahlekileyo, kunye neendleko zabasebenzi kunye neekreyini, I-TIC liner idla ngokunciphisa iindleko ezipheleleyo ezinxulumene ne-liner ngetoni nganye ye-ore etyumkileyo ngama-40-60%..

Q: Ngaba ii-TIC insert liners zingaphatha i-tramp iron okanye izinto ezingagungqiyo?

Le yinkxalabo efanelekileyo. Ngenxa yokuba ii-TIC inserts zisekelwe kwi-carbide (ubulukhuni obuncinci ~2,800–3,200 HV), zibuthathaka ngakumbi kune-matrix yentsimbi ye-manganese kwaye azikwazi ukufunxa inqanaba elifanayo lamandla empembelelo ngaphandle kokuqhekeka. Kwimigodi eneziganeko zentsimbi eziphindaphindayo, ndicebisa ukuba kuchazwe ii-liners ezine: (1) ububanzi obukhulu be-TIC insert (25–28 mm vs. 20 mm) ukuze kwandiswe ukumelana nokuqhekeka kwe-insert, (2) "indawo yempembelelo" engabonakaliyo kwindawo yokutyela engenazo izinto ezifakiweyo okanye uxinano oluncitshisiweyo, kunye (3) ukwahlukana kwemagnethi okanye ukufunyanwa kwesinyithi phezulu kwe-crusher. Akukho sixhobo sokufaka i-TIC esiza kusinda kwiimpembelelo eziphindaphindiweyo ezivela kumazinyo entsimbi yokubhola okanye ebhakethi.

Q: Imozulu yaseNtshona Afrika iyichaphazela njani indawo yokugcina nokufakela ii-TIC insert liner?

Ubushushu obuphezulu kunye nokujikeleza kobushushu eNtshona Afrika (30–45°C kunye nobushushu obuphakathi kwama-70–90%) kudala iingozi ezimbini ezilula ukuzityeshela. Okokuqala, ii-liners ezigciniweyo ezivezwe kwimijikelo yokufuma zinokubangela umhlwa womphezulu ophazamisana nenkqubo yokuqala yokuqina komsebenzi — Ndicebisa ukugcina ii-liners phantsi kwesigqubuthelo nge-VCI (Volatile Corrosion Inhibitor) iphepha lokusonga. Okwesibini, ukufaka i-liner "ebandayo" (egcinwe ubusuku bonke kwi-18-22°C) kwi-crusher esebenza kwi-35-40°C ubushushu obuphakathi kudala uxinzelelo lobushushu kwi-interface ye-insert-matrix. Ndicebisa ukuvumela ii-liners ukuba qhelana nobushushu obuphakathi ubuncinane iiyure ezi-4 ngaphambi kokufakwa.

Q: Yeyiphi impazamo eqhelekileyo eyenziwa yimigodi yaseNtshona Afrika ngee-TIC insert liners?

Ngaphandle kwamathandabuzo, iphatha ii-TIC insert liners "njengendlela yokutshintsha" ii-standard manganese liners ngaphandle kokulungisa iiparameter zokusebenza kwe-crusher. I-CSS efanayo, isantya, kunye nesantya sokutya esisebenzele i-manganese liner siya kuvelisa iziphumo ezingalunganga - kwaye kwimeko embi kakhulu, ukusilela kwangaphambi kwexesha - nge-TIC liner. I-insert-matrix composite iziphatha ngendlela eyahlukileyo phantsi komthwalo. Ndibone imigodi inciphisa ubomi bayo be-TIC liner ngama-35–50% kuba nje benqabile ukwenza uhlengahlengiso oluncinci lokusebenza olufunekayo ukuze luhambelane neempawu ze-liner.
