Emva kokupapashwa koshicilelo luka-Oktobha lweMigodi yaMazwe ngaMazwe, kwaye ngakumbi ngakumbi inqaku lonyaka lokutyunyuzwa nokuhanjiswa emhadini, siye saqwalasela ngakumbi enye yezinto ezingundoqo ezenza ezi nkqubo, i-faskoti feeder.
Emigodini,ifaskoti feedersdlala indima ebalulekileyo ekuqinisekiseni ukusebenza kakuhle kunye nokwandisa ixesha. Izicelo zabo kwiisekethe zokulungisa izimbiwa zihluke kakhulu; nangona kunjalo, amandla abo apheleleyo awaziwa kakuhle kulo lonke ishishini, okukhokelela kwimibuzo emininzi ephakanyisiweyo.
UMartin Yester, iNkxaso yeMveliso yeHlabathi, iMetso Bulk Products, iphendula eminye imibuzo ebaluleke kakhulu.
Ngamagama alula, i-apron feeder (eyaziwa ngokuba yi-pan feeder) luhlobo lomatshini lwe-feeder olusetyenziswa kwimisebenzi yokuphatha izinto eziphathekayo ukuhambisa (ukutya) izinto eziphathekayo kwezinye izixhobo okanye kwi-inventory yokugcina, ibhokisi okanye i-hopper ukukhupha izinto (i-ore / rock) ngesantya esilawulwayo.
Ezi feeder zingasetyenziswa kwiinkqubo ezahlukeneyo kwiprayimari, eyesibini kunye neyesithathu (yokubuyisela) imisebenzi.
I-Trector chain apron feeders ibhekisela kumatyathanga angaphantsi kweekhariji, ii-roller kunye namavili omsila asetyenziswa kwi-bulldozers kunye ne-excavators.Olu hlobo lwe-feeder lulawula amashishini apho abasebenzisi bafuna i-feeder ekwazi ukukhupha izinto ezineempawu ezahlukeneyo.Izitywina ze-Polyurethane kwikhonkco zithintela izinto ezinqabileyo ekungeneni izikhonkwane zangaphakathi kunye ne-excavators yangaphakathi kunye ne-excavators yokwandisa izixhobo zobomi kunye nokunciphisa i-bushings. I-feeders ikwanciphisa ungcoliseko lwengxolo ukwenzela ukusebenza okuthe cwaka.Amakhonkco ekhonkco anyangwa ubushushu ubomi obude.
Ngokubanzi, izibonelelo zibandakanya ukuthembeka okwandisiweyo, iinxalenye ezimbalwa ezisecaleni, ukugcinwa okuncinci kunye nokulawulwa okungcono kokutya.Ukubuyisela, ezi zibonelelo zonyusa imveliso kunye neebhotile ezincinci kuyo nayiphi na i-loop yokucubungula izimbiwa.
Inkolelo eqhelekileyo malungaifaskoti feederskukuba kufuneka zifakwe ngokuthe tye.Kaloku, ngokuchaseneyo nenkolelo ethandwayo, zinokuxhonywa kumathambeka!Oku kuzisa iingenelo ezininzi ezongezelelweyo kunye neempawu.Xa ufaka ifaskoti feeder kwithambeka, indawo encinci iyafuneka iyonke - ayipheleli nje ekunciphiseni isithuba somgangatho wethambeka, ikwanciphisa nobude bokufumana ihopper.Ukutyibilika kwempahla yefaskoti,impahla eyongezelelekileyo iya kwandisa ifaskoti,ichule ziya kwandisa ifaskoti,impahla eyongeziweyo. umthamo kwi-hopper kunye nokunciphisa amaxesha omjikelezo kwiilori zokuthuthwa.
Gcina ukhumbule ukuba kukho izinto ezithile ekufuneka uziqaphele xa ufaka i-pan feeder kwi-slope ukuze uphucule inkqubo.
Ukungaqondi kakuhle okuqhelekileyo malunga nokusebenza nasiphi na isixhobo kukuba: "Ngokukhawuleza kuya kuba ngcono."Ngokubhekiselele kwi-apron feeders, akunjalo.Isantya esiphezulu sivela ekufumaneni ukulingana phakathi kokusebenza kakuhle kunye nesantya sokuthumela.Bahamba ngokukhawuleza kunezondla zebhanti, kodwa ngesizathu esihle.
Ngokuqhelekileyo, isantya esiphezulu se-apron feeder ngu-0.05-0.40 m / s. Ukuba i-ore ayinayo i-abrasive, isantya sinokunyuswa sibe ngaphezu kwe-0.30 m / s ngenxa yokunciphisa kunokwenzeka ukunxiba.
Izantya eziphezulu ziphazamisa ukusebenza: ukuba isantya sakho siphezulu kakhulu, ubeka umngcipheko wokukhawuleza ukunxiba kwiinxalenye.Ukusebenza kakuhle kwamandla kuyancipha ngenxa yokwanda kwemfuno yamandla.
Omnye umba omawuhlale ukhumbula xa uqhuba ifaskoti ngesantya esiphezulu kukwanda kwamathuba esohlwayo.Kunokubakho iziphumo ezirhabaxa phakathi kwezinto kunye nepleyiti.Ngenxa yobukho obunokwenzeka bothuli olubalekayo emoyeni, ukudalwa kwezohlwayo akudali nje iingxaki ezingaphezulu, kodwa kudala indawo yokusebenza eyingozi ngakumbi kubasebenzi xa bebonke. Ke ngoko, ukufumana esona santya siphezulu ukusebenza kwemveliso kubaluleke ngakumbi kwimveliso yezityalo kwaye kubaluleke ngakumbi kukhuseleko lwesityalo.
I-apron feeders inemida xa isiza kubukhulu kunye nodidi lwentsimbi.Izithintelo ziya kwahluka, kodwa imathiriyeli akufuneki ilahlwe ngokungenanjongo kwi-feeder.Kufuneka ungaqwalaseli kuphela isicelo apho uza kusebenzisa khona i-feeder, kodwa nalapho eso sondlo siya kubekwa khona kwinkqubo.
Ngokuqhelekileyo, umgaqo woshishino we-apron feeder sizes ulandele ukuba ububanzi be-pan (i-skirt yangaphakathi) kufuneka buphindwe kabini ubukhulu beyona nto inkulu yezinto eziphathekayo.Ezinye izinto, ezifana ne-hopper evulekileyo eyenzelwe ngokufanelekileyo idibaniswe nokusetyenziswa kwe "rock flip plate", inokuchaphazela ubungakanani bepani, kodwa oku kufanelekileyo kuphela kwiimeko ezithile.
Akuqhelekanga ukukwazi ukukhupha i-1,500mm yezinto eziphathekayo ukuba i-3,000mm i-feeder ebanzi isetyenzisiweyo.Izinto ezingalunganga ze-300mm ezikhutshwe kwiimfumba ze-ore ze-crusher okanye iibhokisi zokugcina / zokuxuba ngokuqhelekileyo zikhutshwa kusetyenziswa i-apron feeder ukondla isityuli sesibini.
Xa ulinganisa i-apron feeder kunye nenkqubo yokuqhuba ehambelanayo (i-motor), njengoko kunye nezixhobo ezininzi zezixhobo kwishishini lemigodi, amava kunye nolwazi lwenkqubo yonke luxabiseke kakhulu.I-Apron feeder sizing idinga ulwazi olusisiseko lwedatha yefektri ukugcwalisa ngokuchanekileyo imilinganiselo efunwa ngumboneleli "Iphepha leDatha leSicelo" (okanye umthengisi ufumana ulwazi lwabo).
Iikhrayitheriya ezisisiseko ekufuneka ziqwalaselwe ziquka izinga lokutya (incopho kunye nesiqhelo), iimpawu zemathiriyeli (ezifana nokufuma, ukuhlelwa kunye nokumila), ubukhulu bebhloko yebhloko yentsimbi ekrwada/ilitye, ukuxinana kobuninzi bentsimbi ekrwada/ilitye (ubuninzi kunye nobuncinci) kunye neemeko zesondlo kunye neOkuphumayo.
Nangona kunjalo, ngamanye amaxesha izinto eziguquguqukayo zingongezwa kwinkqubo yokulinganisa i-apron feeder ekufuneka ibandakanywe.Utshintsho olukhulu olongezelelweyo ekufuneka ababoneleli babuze ngalo luqwalaselo lwe-hopper.Ngokukodwa, i-hopper cut length open (L2) ibekwe ngqo ngentla kwe-faspron feeder.Apho kusebenzayo, le yiparameter engundoqo hayi kuphela ukulinganisa ngokuchanekileyo i-apron feeder, kodwa nakwinkqubo ye-apron yokuqhuba.
Njengoko kukhankanyiwe ngasentla, ubuninzi bobuninzi be-ore / rock yenye yeemfuno ezisisiseko ezisisiseko kwaye kufuneka ibandakanye ubungakanani obusebenzayo be-hoarding feeder.Uxinaniso bubunzima bezinto eziphathekayo kumthamo onikiweyo, ngokuqhelekileyo ubuninzi bobuninzi bulinganiswa ngeetoni nge-cubic meter nganye (t/m³) okanye iipounds per cubic foot (lbs/ft³) . ingxinano njengakwezinye izixhobo zokulungisa izimbiwa.
Ngoko kutheni le nto i-bulk density ibaluleke kangaka?I-Apron feeders zi-volumetric feeders, nto leyo ethetha ukuba ukuxinana kwesambuku kusetyenziselwa ukumisela isantya kunye namandla afunekayo ukukhupha i-tonnage ethile yezinto ngeyure.Ubuninzi bobuninzi obuncinane busetyenziselwa ukumisela isantya, kwaye ubuninzi bobuninzi bobuninzi bumisela amandla (torque) afunwa ngumxhasi.
Kuzo zonke, kubalulekile ukusebenzisa ubuninzi obuchanekileyo "ubuninzi" kunobuninzi "obuqinileyo" ubungakanani be-apron feeder yakho.Ukuba ezi zibalo azichanekanga, umlinganiselo wokugqibela wesondlo wenkqubo ephantsi komlambo unokuphazamiseka.
Ukumisela ubude be-hopper shear licandelo elibalulekileyo ekumiselweni okuchanekileyo kunye nokukhethwa kwe-apron feeder kunye nenkqubo yokuqhuba (i-motor).Kodwa ingaba le nto iqinisekileyo?Ubude be-hopper ye-shear yi-dimensional ukusuka kwi-skirted hopper umva ipleyiti ukuya kwi-bar yokucheba ekupheleni kwe-hopper.Kuvakala kulula, kodwa kubalulekile ukuqaphela ukuba le nto ayifanele idideke kunye nobukhulu be-hopper.
Injongo yokufumana lo mlinganiso wobude be-hopper kukufumanisa umgca wendiza yokucheba yeyona nto kwaye apho izinto ezikwi-skirt zahlula (i-shears) kwizinto eziphathekayo (L2) kwi-hopper.Ukumelana nokucheba kwezinto ngokuqhelekileyo kuqikelelwa ukuba kuphakathi kwe-50-70% ye-total force / power.Olu balo lobude be-shear luya kubangela nokuba kungaphantsi kwamandla (ukulahlekelwa kwamandla) okanye ukulahlekelwa kwamandla okusebenza (ukulahlekelwa kwamandla) (ukulahlekelwa yinkcitho)
Isithuba sezixhobo sibalulekile kuwo nawuphi na umatshini.Njengoko kukhankanyiwe ngaphambili, i-apron feeder inokuxhonywa kumathambeka ukugcina indawo.Ukukhetha ubude obuchanekileyo be-apron feeder akunakunciphisa kuphela inkcitho enkulu (i-capex), kodwa nokunciphisa ukusetyenziswa kwamandla kunye neendleko zokusebenza.
Kodwa ubude obufanelekileyo bunqunywe njani?Ubude obude be-apron feeder yinto enokuthi ihlangabezane nomsebenzi ofunekayo kubude obufutshane kakhulu.Nangona kunjalo, kwezinye iimeko, ekusebenzeni, ukhetho lwe-feeder lungathatha ixesha elide "ukudlulisa" izinto kwizixhobo ezisezantsi kunye nokuphelisa iindawo zokudlulisa (kunye neendleko ezingeyomfuneko).
Ukumisela i-feeder emfutshane kunye neyona ndlela ingcono kakhulu, i-apron feeder kufuneka ibekwe ngokuguquguqukayo phantsi kwe-hopper (L2) .Emva kokumisela ubude be-shear kunye nobunzulu bebhedi, ubude obupheleleyo bunokuncitshiswa ukuthintela okubizwa ngokuba yi-"self-flushing" ekupheleni kokukhutshwa xa i-feeder ingasebenzi.
Ukukhetha inkqubo efanelekileyo yokuqhuba i-apron feeder yakho iya kuxhomekeka ekusebenzeni kunye neenjongo ze-feeder.I-Apron Feeders yenzelwe ukusebenza ngesantya esiguquguqukayo ukukhupha kwindawo yokugcina kunye nokutya okusezantsi kwizinga elilawulwayo lokuphumelela okuphezulu.
Iindidi ezimbini zokuqhuba ezilungele isantya esiguquguqukayo zisebenzisa izixhobo zokunciphisa i-gear, ii-motor frequency frequency motors kunye ne-variable frequency drives (VFDs), okanye ii-hydraulic motors kunye neeyunithi zamandla ezineempompo zokufuduka eziguquguqukayo.Namhlanje, i-speed drive mechanical drives ibonakalise ukuba yinkqubo yokuqhuba ekhethiweyo ngenxa yenkqubela phambili yezobuchwepheshe kunye neenzuzo zenkcitho enkulu.
Iinkqubo ze-hydraulic drive zinendawo yazo, kodwa azijongwa njengefanelekileyo phakathi kweedrive ezimbini eziguquguqukayo.
