Abaphathi boLondolozo lweeNqwelo zeMigodi yeQuarry Cacisa iinxalenye ze-GET ezinee-Hardened Cutting Edges ze-Bulldozer Push Operations

Oko Ndikufundileyo Malunga neFUMANA Inkcazelo yeeQuarry Bulldozers Emva kweminyaka eli-10 yokunikezelwa kwezixhobo zokunxiba emigodini

Xa ndandiqala ukubonelela ngezixhobo zokubandakanya umhlaba (i-GET) kwimisebenzi yokwemba imigodi ngo-2015, eyona mpazamo ixhaphakileyo endayibona abaphathi bolondolozo lweenqwelo-mafutha beyenza yayikukucacisa imiphetho ye-GET ngokusekelwe kwixabiso lodwa - ukuthenga ukhetho olungabizi kakhulu oluya kuhambelana nezixhobo zabo ngaphandle kokuqwalasela ukurhawuzelelwa kwezinto zemigodi, iiyure zokusebenza ngosuku, okanye iindleko zizonke zokusetyenziswa kwe-GET kulo lonke ixesha lezixhobo. Isiphumo saba kukuguguleka kwangethuba (xa intsimbi ephantsi yayisetyenziswa kwiimeko zokurhawuzelelwa okuphezulu) okanye iindleko ezigqithisileyo (xa iincam ze-tungsten carbide zeprimiyamu zazisetyenziswa kwiimeko zokurhawuzelelwa okuphantsi apho intsimbi ephathwa ngobushushu eqhelekileyo yayiya kwanela).

Kwiminyaka eli-10 edlulileyo, ndinikezele ngeemveliso ze-GET kwimisebenzi yokwamba kulo lonke elaseMzantsi-mpuma Asia, eMbindi Mpuma, naseMbindi Asia, ukusuka kwiindawo ezincinci zelitye lekalika ezisebenza kusapho ezivelisa iitoni ezingama-50,000 ngonyaka ukuya kwimisebenzi emikhulu yelitye le-granite evelisa iitoni ezi-2 zezigidi ngonyaka. Ndenze izifundo zesantya sokuguguleka, ndahlalutya iindleko zizonke zokusetyenziswa kwe-GET ngetoni yezinto ezifudusiweyo, ndaza ndasebenza namaqela olondolozo ukuze ndiphucule amaxesha okutshintsha kwe-GET kunye neendlela zokusebenza. Endikufundileyo kukuba iinkcukacha ze-GET sisigqibo sobunjineli esiqhutywa yidatha, asisosigqibo sokuthenga, kwaye iinkcukacha ezifanelekileyo zinokunciphisa iindleko ze-GET zizonke ngama-30-50% xa kuthelekiswa nenkcazo engenamsebenzi esekelwe kwixabiso lokuqala eliphantsi.

Ukuqonda iTekhnoloji ye-GET: Iinkqubo zeNtsimbi enye xa kuthelekiswa neWelded-Tippet

Izixhobo zokubandakanya umhlaba kwiibhuldozer ze-quarry ziyafumaneka kwiindlela ezimbini eziphambili zokucwangcisa inkqubo: i-single-steel (apho i-adaptha kunye nomphetho wokusika ziyi-single cast okanye i-forged component) kunye ne-welded-tippet (apho i-cast tip eyahlukileyo i-welded okanye itshixelwe ngoomatshini kwi-adaptha yentsimbi). Ukukhetha phakathi kwezi nkqubo kunefuthe elibalulekileyo kwiindleko zokusebenza, indlela yokulungisa, kunye nomngcipheko wezixhobo.

Iinkqubo ze-GET zeNtsimbi enye

Iinkqubo ze-GET zentsimbi enye ziyindlela yendabuko yokusika imiphetho ye-bulldozer kwaye zihlala zisemgangathweni kwimisebenzi emininzi ye-quarry. Inxalenye yonke - ukusuka kwindlela yokutshixa ebamba i-dozer blade shank ukuya kumphetho wokusika odibana nezinto ze-quarry - sisiqwenga esinye sentsimbi ye-alloy ephathwa ngobushushu. Xa umphetho wokusika uphela okanye uqhekeka, yonke inxalenye iyasuswa kwaye ithathelwe indawo entsha.

Iingenelo zeenkqubo zentsimbi enye kukulula (akukho zi-welds ekufuneka zigcinwe, akukho zixhobo zokugcina iincam ekufuneka zihlolwe, kwaye akukho mngcipheko wokulahleka kwencam ngexesha lokusebenza) kunye nokuthembeka (i-GET yentsimbi enye efakwe ngokufanelekileyo ayizukusilela ngendlela ebangela umonakalo weblade). Ingxaki yindleko: xa umda wokusika uguga emva kweeyure ezingama-200-600 zokusebenza, lonke icandelo - kuquka nenxalenye ye-adaptha engakhange iguge kwaphela - kufuneka itshintshwe. Kwizinto zomngxuma ophezulu apho umda wokusika uguga ngokukhawuleza, oku kuthetha ukutshintsha i-adaptha enganxitywanga engama-70-80% rhoqo emva kweeyure ezingama-200-400, nto leyo echitha imali eninzi.

Iinkqubo ze-GET ezidityanisiweyo

Iinkqubo ze-GET ezinee-tippet ezidityanisiweyo zijongana nokungasebenzi kakuhle kwezoqoqosho kweenkqubo zentsimbi enye ngokwahlula icandelo lokuguguleka (incam) kwicandelo lesakhiwo (i-adaptha). Xa incam iguguleka, incam kuphela etshintshwayo — i-adaptha ihlala ifakiwe kwi-dozer blade, kwaye incam entsha iyatshixwa okanye itshixwe ngoomatshini endaweni yayo. Kwimisebenzi ye-quarry ephezulu, oku kunokunciphisa iindleko zokusebenza ze-GET ngama-30-40% kuba iindleko ze-adaptha ziyancitshiswa ngenxa yokutshintshwa kwee-tip ezininzi.

Nangona kunjalo, iinkqubo ze-welded-tippet zizisa iingozi ezingekhoyo kwiinkqubo zentsimbi enye. I-weld ephakathi kwencam kunye ne-adapter yindibaniselwano ebalulekileyo yesakhiwo ejongene noxinzelelo oluphezulu oluvela kwi-冲击 kunye nokukrala kwezinto ze-quarry. Ukuba i-weld ayenzelwanga ngokweemfuno zemigodi (ngesiqhelo i-AWS D14.1 okanye elinganayo), okanye ukuba i-weld ayihlolwa rhoqo ukuba ayinayo imifantu kunye nokudinwa, ukungaphumeleli kwe-tip weld ngexesha lokusebenza kunokubangela ukuba incam iqhekeke kwaye ibe yi-projectile enesantya esiphezulu ngaphakathi kwe-quarry, okanye ingabangela umonakalo kwi-dozer blade ebiza amaxesha ama-5-10 kuneendleko ze-GET zokulungisa. Kumava am, umngcipheko wokungaphumeleli kwe-weld sesona sizathu siphambili sokuba abanye abaqhubi be-quarry bakhethe iinkqubo zentsimbi enye - bayamkela iindleko eziphezulu zokutshintsha ngokutshintshiselana nokususwa komngcipheko wokungaphumeleli kwe-weld.

Indlela yesithathu ethintela ukungasebenzi kakuhle kweendleko zentsimbi enye kunye nomngcipheko we-weld we-weld-tippet yinkqubo ye-mechanical-lock tip, apho i-tip ibanjwa kwi-adaptha yinkqubo yokugcina umatshini (i-locking pin, i-SetRing, okanye inkqubo ye-wedge) endaweni yokuyidibanisa. Ii-mechanical-lock tips zingatshintshwa kwimizuzu emi-5-10 (xa kuthelekiswa nemizuzu engama-30-60 kwi-welded tip), kwaye ziyayisusa ngokupheleleyo ingozi yokungaphumeleli kwe-weld, kodwa zifuna ukuhlolwa rhoqo kunye nokugcinwa kwendlela yokutshixa ukuqinisekisa ukuba ii-tips azilahleki ngexesha lokusebenza. Ndicebisa ngakumbi iinkqubo zokutshixa ze-mechanical kwimisebenzi ye-quarry apho umgangatho wokugcinwa uguquguquka kwaye apho iziphumo zesiganeko sokulahlekelwa yi-tip zinzima.

Ukukhethwa koBume beZinto Ngokusekelwe kwiQuari Izinto eziQhaqhayo

Ukurhawuzelelwa kwezinto ze-quarry yeyona nto iphambili ekukhetheni umgangatho wezinto ze-GET, kwaye ukufanisa umgangatho wezinto kunye nokurhawuzelelwa sesona sigqibo sibalulekileyo kwi-GET specification. Ukurhawuzelelwa kwezinto ze-quarry kulinganiswa ngovavanyo lwelebhu oluqhelekileyo: uvavanyo lokurhawuzelelwa lwaseLos Angeles (LA75) lulinganisa ukulahleka kobunzima besampulu yentsimbi esemgangathweni emva kokujikeleza okungama-500 ngezinto ze-quarry; i-Cerchar abrasivity index (CAI) ilinganisa ubunzima bokukrwela kwezinto ze-quarry kwi-stylus yentsimbi. Zombini ezi vavanyo zibonelela ngedatha eluncedo, kwaye ndihlala ndisebenzisa i-LA75 njenge-parameter ye-specification ephambili kuba ihambelana ngcono nobomi bokunxiba be-GET kumava am entsimi.

Izixhobo ezingarhawuzeleliyo kakhulu (iLimestone, iMarble, iGypsum)

Iingcamba zeLimestone, zemabula, kunye negypsum zinexabiso le-LA75 eliphakathi kwama-20-30 (oko kuthetha ukuba le nto ibangela ukulahleka kobunzima obuyi-20-30% kuvavanyo lwe-LA75) kunye nee-Cerchar indices ze-0.5-1.5. Ezi zinto zithambile kwaye zibangela ukuguguleka okuphakathi kwimiphetho yokusika ye-GET. Kwezi zicelo, ndichaza imiphetho yokusika yentsimbi enganyangekiyo enobunzima beBrinell obuyi-400-500 HB, obubonelela ngobomi bokuguguleka obaneleyo (iiyure zokusebenza ezingama-300-600 ngeseti nganye ye-tip ye-320HP bulldozers) ngexabiso eliphantsi elifanelekileyo. I-Tungsten carbide okanye i-chrome carbide tips ngokubanzi azibizi kakhulu kwizixhobo ezinganyangekiyo kuba ukuphuculwa kobomi bokuguguleka okukhawulezileyo akuthetheleli ixabiso eliphezulu le-3-5x lenxalenye.

Izixhobo eziPhakathi zokurhawuzelela (iSandstone, iGravel, iIron Ore)

Ilitye lesanti, ezinye iinxalenye zegrabile, kunye needipozithi zesinyithi ezikumgangatho ophantsi zinexabiso le-LA75 kuluhlu lwe-40-60 kunye ne-Cerchar indices ze-2.0-3.5. Ezi zinto zibangela ukuguguleka okukhulu okuya kunciphisa ngokukhawuleza intsimbi ephathwa ngobushushu esemgangathweni. GET. Kwezi zicelo, ndichaza intsimbi ephakathi ephathwa ngobushushu enokongeza i-chromium (ngesiqhelo i-2-4% ye-chromium) ukwandisa ubunzima kunye nokumelana nokuguguleka, kunye nobunzima beBrinell obuyi-500-600 HB. Ukongezwa kwe-chromium kwandisa iindleko malunga ne-15-25% xa kuthelekiswa nentsimbi eqhelekileyo ephathwa ngobushushu kodwa kwandisa ubomi bokuguguleka ngo-50-100%, okwenza kube nexabiso elifanelekileyo kwizicelo zokuguguleka okuphakathi. Okanye, ndichaza ipleyiti yokugquma ye-chrome carbide ebusweni obuphambili ukuze kube sisisombululo esingabizi kakhulu kwizixhobo zokuguguleka okuphakathi - ukugquguleka kunika ubunzima bomphezulu obuyi-600-700 HB ngelixa i-substrate ihlala iyintsimbi eqinileyo ye-alloy.

Izinto ezirhabaxa kakhulu (iGranite, iBasalt, iQuartzite)

I-granite, i-basalt, i-quartzite, kunye nezinye izinto zentsimbi eqinileyo zinexabiso le-LA75 eliphakathi kwe-70-100 kunye ne-Cerchar indices ze-4.0-6.0. Ezi zinto ziphakathi kwezinto zendalo ezirhabaxa kakhulu ezifunyanwa ekuqhekezweni kwemigodi, kwaye intsimbi eqhelekileyo ephathwa ngobushushu i-GET inokuguga kwiiyure zokusebenza ezingama-50-100 phantsi kwezi meko. Kwizicelo zokurhabaxa okuphezulu, ndichaza iincam ze-tungsten carbide composite (ezinobunzima obukhulu be-1,500-1,800 HB) okanye iipleyiti ze-alloy ezimelana nokurhabaxa ezizimeleyo ezinobunzima obuphezulu kakhulu (umphezulu we-650-700 HB). Ixabiso lezi zinto zeprimiyamu liphindwe kathathu ukuya kwi-10 yexabiso lentsimbi eqhelekileyo ephathwa ngobushushu, kodwa ubomi obude bokurhabaxa (iiyure zokusebenza ezili-1,000-4,000 kuxhomekeke kudidi oluthile lwezinto kunye nokurhabaxa kwezinto ze-quarry) zizenza zibe lolona khetho lungabizi kakhulu xa kubalwa iindleko ezipheleleyo zexesha lokungasebenzi, umsebenzi, kunye nokulahleka kwemveliso.

Ixabiso lokwenyani lokuNxiba kwe-GET kwimisebenzi yeQuarry

Ixabiso lokuguguleka kwe-GET kwimisebenzi ye-quarry liphezulu kakhulu kunokuba uninzi lwabaphathi be-quarry beqonda, kuba ixabiso lenxalenye ethe ngqo lincinci kakhulu kunexabiso lilonke. Ngokwamava am okuhlalutya idatha yeendleko ze-GET evela kwimisebenzi ye-quarry kumazwe amaninzi, ixabiso lilonke lokuguguleka kwe-GET lihla ngolu hlobo lulandelayo: i-20-30% lixabiso elithe ngqo leenxalenye ze-GET (iingcebiso, ii-adapters, imiphetho yokusika); i-30-40% lixabiso lomsebenzi wexesha lokungasebenzi lokutshintsha kwe-GET kunye nokugcinwa kweeblade; kwaye i-40-50% lixabiso lokulahleka kwemveliso kunye nomonakalo wesibini kwisakhiwo se-dozer blade esibangelwa kukusebenza kwe-GET okugugulekileyo ngaphaya kwenqanaba lokutshintsha elicetyiswayo.

Impembelelo yemveliso ye-Worn GET

Xa imiphetho yokusika yeGET iguga idlula indawo yokutshintsha ecetyiswayo, ukusebenza kakuhle kokutyhala kwedozer kwehla kakhulu. I-bulldozer eneGET egcinwe kakuhle inokutyhala izinto ezingaphezulu nge-15-25% ngeyure kunomatshini ofanayo oneGET egugileyo esebenza kwiimeko ezifanayo. Oku kulahleka kwemveliso akusoloko kubonakala kuba iqokelelana kancinci kancinci njengoko iGET iguga, kodwa ngosuku olupheleleyo lwemveliso, umahluko phakathi kweGET egcinwe kakuhle negugileyo unokumela ukwehla kwe-10-20% kwizinto ezifuduswayo zemihla ngemihla - nto leyo ngexabiso lesango le-quarry eliyi-USD 10-30 ngetoni imele i-USD 1,000-5,000 ngosuku kwingeniso elahlekileyo yomsebenzi we-quarry ophakathi.

Umonakalo wesibini obangelwa yi-GET egugileyo mhlawumbi yeyona nto ingaphantsi kwexabiso. Xa umphetho wokusika uphela ude ufikelele kwinqanaba apho ungasaboneleli ngomphezulu wokusika obukhali, i-dozer blade iqala ukunyuka phezu kwento endaweni yokuyinqumla ngokucocekileyo. Oku kubangela ukuba i-blade iqhagamshelane nomphezulu womhlaba kwaye iipleyiti zamaphiko zikrwele kwizinto ezinganqunyulwanga, nto leyo ekhawulezisa ukuguguleka kweepleyiti ezisezantsi ze-blade, iipleyiti zamaphiko, kunye noqhagamshelo lweengalo ezityhalwayo. Ndibone ukulungiswa kwesakhiwo se-dozer blade okubiza i-USD 8,000-25,000 - izihlandlo ezihlanu ukuya kwezilishumi zexabiso le-GET lonyaka - ezibangelwe kukusebenza ne-GET egugileyo ngaphaya kwendawo yokutshintsha ecetyiswayo.

FUMANA Ucwangciso lweXesha lokutshintsha lweMisebenzi yeeNqwelo zeQuarry

Ixesha lokutshintsha kwe-GET kwii-quarry bulldozers kufuneka lisekelwe ekugugulekeni okulinganisiweyo, kungekhona kwishedyuli emiselweyo, kuba ukurhawuzelelwa kwezinto ze-quarry kuyahluka phakathi kweendawo ze-quarry, phakathi kweebhentshi, naphakathi kwexesha lonyaka. Nangona kunjalo, uninzi lwemisebenzi ye-quarry ifuna indawo yokuqala yokucwangcisa ukugcinwa kwayo, kwaye ndibonelela ngezikhokelo ezilandelayo ezisekelwe kuhlobo lwezinto ze-quarry kunye nodidi lobungakanani be-dozer, kunye nengcebiso yokuba abaqhubi bahlengahlengise amaxesha ngokusekelwe kumlinganiselo wokwenyani wentsimi.

Iprotocol yoHlolo

Ndicebisa uhlolo lwe-GET olubonakalayo rhoqo xa kutshintshwa utshintsho — rhoqo emva kweeyure ezisi-8 okanye ezili-12 zokusebenza — oluthatha umqhubi oqeqeshiweyo okanye ingcali yokulungisa malunga nemizuzu emi-5 ukwenza. Uhlolo kufuneka lujonge: ukuguguleka kwempumlo yencam (linganisa ubude bempumlo eseleyo ukusuka kwimpumlo yencam ukuya egxalabeni le-adaptha — yitshintshe ukuba ingaphakathi kwe-10mm ukusuka egxalabeni le-adaptha); ukuqhekeka okubonakalayo (khangela ukuqhekeka okuvela kwimpumlo yencam ukuya kwi-interface ye-adaptha — naluphi na ukuqhekeka okungaphezulu kwe-5mm ubude kufuna ukutshintshwa kwencam ngoko nangoko); ukugcinwa kwencam (kwiinkqubo zokutshixa ngoomatshini kunye ne-welded-tippet, qinisekisa ukuba iincam zikhuselekile kwaye indlela yokugcina ayiguquki); kunye nemeko ye-adaptha (jonga iindawo zokutshixa ze-adaptha ezigobileyo okanye ezigugileyo ezinokuthintela ukuhlala kakuhle kwencam).

Amaxesha otshintsho olucwangcisiweyo

Kwizicwangciso zokuqala zokulungisa, ndicebisa la maxesha okutshintsha kwe-GET alandelayo njengeendawo zokuqala, ahlengahlengiswe ngokusekelwe kwidatha yovavanyo yokwenyani: kwiibulldozer zeklasi ezingama-320HP (eziqhelekileyo kwiingcibi zelitye eliphakathi) kwilitye eliyinkuni (LA75 20-30): tshintsha iincam kwiiyure zokusebenza ezingama-300-500; kwilitye lesanti (LA75 40-60): tshintsha iincam kwiiyure zokusebenza ezingama-200-400; kwigranite/basalt (LA75 70-100): tshintsha iincam kwiiyure zokusebenza ezili-100-200 ngeencopho ze-tungsten carbide. Kwiibulldozer zeklasi ezingama-520HP (eziqhelekileyo kwiingcibi ezinkulu): linganisa amaxesha angentla nge-0.8, kuba izixhobo ezinkulu zinexabiso eliphezulu le-GET ngeyure yokusebenza ngenxa yobukhulu beencopho ezibandakanyekayo.

Ngokuphathelele imigangatho yokuguguleka kwezixhobo zemigodi, qhagamshelana noI-ISO 10414imigangatho yezixhobo zokubhola amatye kunyeI-SAE yaMazwe ngaMazweizikhokelo zeenkcukacha zezixhobo zokunxiba zezixhobo zokuhambisa umhlaba.

Imibuzo ebuzwa qho

Yintoni umahluko phakathi kweenkqubo ze-GET ezinentsimbi enye kunye neenkqubo ze-welded-tippet ze-quarry bulldozers?

Iinkqubo ze-GET zentsimbi enye zisebenzisa i-cast-piece enye okanye izinto ezibunjiweyo apho i-adaptha kunye nomphetho wokusika ziyinxalenye enye - xa umphetho wokusika uphela, yonke into iyatshintshwa, kuquka ne-adaptha enganxitywanga. Iinkqubo ze-Welded-tippet zisebenzisa i-tip cast eyahlukileyo etshixiweyo okanye etshixiweyo ngoomatshini kwi-adaptha yentsimbi - kuphela i-tip egugileyo etshixwayo xa iphela, nto leyo enciphisa iindleko zokusebenza ngama-30-40%. I-Single-steel inika ubulula kunye nomngcipheko wokulahlekelwa yi-tip; i-welded-tippet inciphisa iindleko kodwa izisa umngcipheko wokungaphumeleli kwe-weld. Iinkqubo ze-mechanical-lock tip zibonelela ngokhetho lwesithathu - ukutshintsha i-tip ngaphandle kwe-welding kwaye ngaphandle komngcipheko wokungaphumeleli kwe-weld.

Umgangatho wezinto ezibonakalayo uchaphazela njani ubomi bokuguguleka kwe-GET kwizicelo ze-quarry?

Udidi lwezinto zezona zinto ziphambili ezibangela ubomi bokuguguleka obuphambili be-GET. Intsimbi yekhabhoni eqhelekileyo (300-400 HB) iguguleka kwiiyure ezili-100-200 kwilitye lekalika elirhabaxa. Intsimbi enyibilikisiweyo eshushu (450-550 HB) yandisa ubomi bokuguguleka ukuya kwiiyure ezingama-300-500. I-Chrome carbide overlay (600-700 HB) yandisa ubomi bokuguguleka ukuya kwiiyure ezingama-600-1,000. Iingcebiso ze-Tungsten carbide composite (1,500-1,800 HB) zinokwandisa ubomi bokuguguleka ukuya kwiiyure ezingama-2,000-4,000 kwiimeko ezinzima zokuguguleka. Udidi oluchanekileyo kufuneka luhambelane ne-LA75 okanye i-Cerchar abrasiveness index yezinto ze-quarry - ukusebenzisa izinto zeprimiyamu kwizinto ezirhabaxa eziphantsi kuchitha imali, ngelixa ukusebenzisa intsimbi eqhelekileyo kwizinto ezirhabaxa eziphezulu kubangela ukuguguleka okukhulu kunye nomonakalo wesibini.

Ingakanani ixabiso lokwenyani lokuguguleka kwe-GET kwimisebenzi yokwemba imigodi ye-quarry?

Ixabiso lilonke lokunxitywa kwe-GET liquka: (1) Ixabiso lenxalenye ye-GET ngqo — 20-30% iyonke; (2) Ixabiso lomsebenzi wokutshintsha — 30-40% iyonke (iiyure ezi-2-4 ixesha lokungasebenzi ngesiganeko ngasinye sotshintsho); (3) Ukulahleka kwemveliso ngenxa ye-GET egugileyo kunciphisa ukusebenza kakuhle kokutyhala nge-15-25% — 20-30% iyonke; (4) Umonakalo wesibini kwiipleyiti zamaphiko eebhleyidi, iingalo zokutyhala, kunye neepleyiti zokunxitywa ezisezantsi — 20-30% iyonke. Ixabiso lilonke linokufikelela kwi-USD 3-8 ngeyure yokusebenza kwiimeko ezinzima ze-quarry. Ixabiso lokulungiswa kwesakhiwo seebhleyidi okubangelwa kukusebenza nge-GET egugileyo ngaphaya kwendawo yokutshintsha ecetyiswayo linokufikelela kwi-USD 8,000-25,000 ngesiganeko ngasinye — 5-10x yexabiso le-GET lonyaka.

Ukurhawuzelelwa kwezinto eziqhelekileyo ze-quarry kuyichaphazela njani indlela yokukhetha i-GET?

Ukurhawuzelela kwezinto ze-quarry kwahluka kakhulu: i-limestone ethambileyo (LA75 20-30, Cerchar 0.5-1.0) isebenzisa intsimbi ephathwa ngobushushu eyi-450-500 HB enobomi bokugquma obuziiyure ezingama-300-600. Ilitye lesanti kunye negravel ezinoburhabaxa obuphakathi (LA75 40-60, Cerchar 2.0-3.0) ifuna i-chrome carbide engaphezulu kwe-550-650 HB enobomi bokugquma obuziiyure ezingama-300-500. I-granite kunye ne-basalt enoburhabaxa obuziiyure ezininzi (LA75 70-100, Cerchar 4.0-6.0) ifuna iincam ze-tungsten carbide okanye ii-alloys zobunzima obuziiyure ezininzi (650-700 HB) ezinobomi bokugquma obuziiyure ezingama-400-2,000 kuxhomekeke kudidi. Soloko uvavanya okanye ufumane idatha ye-LA75/Cerchar yezinto zakho ze-quarry ngaphambi kokuba uchaze umgangatho wezinto ze-GET.

Liliphi ixesha lokutshintsha i-GET abaphathi beenqwelo-mafutha abafanele balisebenzise kwiibulldozer?

Amaxesha okutshintsha isiseko ngokwexesha elilinganisiweyo lokuguguleka, hayi ixesha lekhalenda. Kwii-bulldozers zeklasi ezingama-320HP kwilitye lekalika: iiyure zokusebenza ezingama-300-500 ngeseti nganye yencam. Kwilitye lesanti: iiyure zokusebenza ezingama-200-400. Kwi-granite/basalt: iiyure zokusebenza ezili-100-200 ngeencam ze-tungsten carbide. Kwii-bulldozers zeklasi ezingama-520HP, nciphisa amaxesha okutshintsha malunga nama-20%. Hlola utshintsho ngalunye (rhoqo emva kweeyure ezi-8-12) kwaye utshintshe xa impumlo yencam igugulekile ukuya kwi-10mm ukusuka egxalabeni le-adapter, naluphi na uqhekeko olubonakalayo ukusuka empumlweni ukuya kwi-adapter ludlula i-5mm, okanye ukwehla kobunzima kudlula i-15% yoqobo. Ukusebenza ngaphaya kwale mida kwandisa kakhulu umngcipheko womonakalo wesibini.
