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 (ekwabizwa ngokuba yi-pan feeder) luhlobo lomatshini lokutyisa olusetyenziswa kwimisebenzi yokuphatha izinto ukuhambisa (ukutya) imathiriyeli kwezinye izixhobo okanye kuluhlu lwezinto zokugcina, ibhokisi okanye ihopper ukukhupha izinto (intsimbi ekrwada/ilitye). ) ngesantya esilawulwayo.
Ezi feeder zingasetyenziswa kwiinkqubo ezahlukeneyo kwiprayimari, eyesibini kunye neyesithathu (yokubuyisela) imisebenzi.
I-Trector chain apron feeders ibhekisela kumatyathanga angaphantsi kwekhariji, iirola kunye namavili omsila asetyenziswa kwi-bulldozers kunye ne-excavators.Olu hlobo lwesondlo lulawula amashishini apho abasebenzisi bafuna i-feeder ekwazi ukukhupha izinto ezineempawu ezahlukeneyo. ukungena kwizikhonkwane zangaphakathi kunye namatyholo, ukunciphisa ukuguga kunye nokwandisa ubomi besixhobo xa kuthelekiswa namatyathanga omileyo.Izixhobo zefaskoti zeTrektara zetyathanga zikwanciphisa 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.Ke, ngokuchaseneyo nenkolelo ethandwayo, zinokuxhonywa kumathambeka!Oku kuzisa iinzuzo ezininzi ezongezelelweyo kunye neempawu.Xa ufaka i-faskoti feeder kwithambeka, kufuneka indawo encinci iyonke - ayipheleli nje ekuthambekeni. ukunciphisa indawo yomgangatho, kwakhona kunciphisa ukuphakama kokufumana i-hopper.I-apron feeder ezityayo zixolela ngakumbi xa kufikwa kwiinqununu ezinkulu zezinto kwaye, ngokubanzi, ziya kwandisa umthamo kwi-hopper kunye nokunciphisa amaxesha omjikelo kwiilori zokuthuthwa.
Gcina ukhumbule ukuba kukho izinto ezithile ekufuneka uziqaphele xa ufaka i-pan feeder kwithambeka ukuze uphucule inkqubo. yonke imiba ephambili.
Ukungaqondi kakuhle okuqhelekileyo malunga nokusebenza nasiphi na isixhobo yile: "Ngokukhawuleza ngcono."Ngokubhekiselele kwi-faskoti feeder ukuya, akunjalo.Isantya esiphezulu sivela ekufumaneni ukulingana phakathi kokusebenza kakuhle kunye nesantya sokuthumela.Zihamba kancinci kunezondla zebhanti, kodwa ngesizathu esivakalayo.
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 omele ugcinwe engqondweni xa uqhuba i-apron feeder ngesantya esiphezulu kukunyuka kwamathuba esohlwayo.Kusenokubakho iziphumo ezirhabaxa phakathi kwezinto kunye nepleyiti.Ngenxa yobukho obunokwenzeka bothuli olubalekayo emoyeni, ukudalwa kwezohlwayo kudala iingxaki ezingaphezulu kuphela, kodwa kwakhona kudala indawo yokusebenza eyingozi ngakumbi kubasebenzi bebonke.Ngoko ke, ukufumana esona santya siphezulu kubaluleke ngakumbi kwimveliso yezityalo kunye nokhuseleko lokusebenza.
I-apron feeders zinemida xa isiza kubukhulu kunye nodidi lwentsimbi ekrwada.Izithintelo ziyakwahluka, kodwa imathiriyeli akufuneki ilahlwe ngokungenanjongo kwi-feeder.Kufuneka uqwalasele kungekuphela nje isicelo apho uya kusebenzisa khona i-feeder, kodwa nalapho oko Isondlo siya kufakwa kwinkqubo.
Ngokubanzi, umthetho kushishino ifaskoti feeder ubungakanani ulandele ukuba ububanzi pan (umbhinqo wangaphakathi) kufuneka kabini ubukhulu iqhekeza inkulu material.Ezinye izinto, ezifana ihopper evulekileyo eyilwe ngokufanelekileyo kudityaniswe nokusetyenziswa "i-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 ezimbi ze-300mm ezikhutshwe kwiimfumba ze-crusher ore okanye iibhokisi zokugcina / zokuxuba ngokuqhelekileyo zikhutshwa kusetyenziswa i-apron feeder ukondla isityuli sesibini.
Xa ukulinganisa i-apron feeder kunye nenkqubo yokuqhuba ehambelanayo (i-motor), njengoko kuninzi lwamaqhekeza ezixhobo kwishishini lemigodi, amava kunye nolwazi lwenkqubo yonke lubaluleke kakhulu. ifunwa ngumboneleli “kwiPhepha leDatha yeSicelo” (okanye umboneleli ufumana ulwazi lwakhe).
Iikhrayitheriya ezisisiseko ekufuneka ziqwalaselwe zibandakanya izinga lokutya (incopho kunye nesiqhelo), iimpawu zemathiriyeli (ezifana nokufuma, ukuhlelwa kunye nokumila), ubukhulu bebhloko yebhloko yentsimbi ekrwada/ilitye, ukuxinana kwentsimbi ekrwada/ilitye (ubuninzi kunye nobuncinci) kunye nokutya kunye iimeko.
Nangona kunjalo, ngamanye amaxesha izinto eziguquguqukayo zinokongezwa kwinkqubo yokulinganisa i-apron feeder ekufuneka iqukwe.Inguqu enkulu eyongezelelweyo eyongezelelweyo ababoneleli kufuneka babuze ngayo kuqwalaselo lwe-hopper.Ngokukodwa, i-hopper cut length opening (L2) ibekwe ngqo phezu kwefaskoti. esebenzayo, le iparameter engundoqo hayi kuphela ukulinganisa ngokuchanekileyo i-apron feeder, kodwa nakwinkqubo yokuqhuba.
Njengoko kukhankanyiwe ngasentla, ubuninzi bobuninzi bentsimbi ekrwada/yelitye yenye yeemfuno ezisisiseko ezisisiseko kwaye kufuneka iquke ubungakanani obusebenzayo besixhobo sokuhombisa. /m³) okanye iipounds ngecubic foot (lbs/ft³). Inqaku elikhethekileyo ekufuneka likhunjulwe kukuba uxinaniso lwesambuku lusetyenziselwa i-faskoti feeder, hayi ukuqina kokuqina njengezinye izixhobo zokusetyenzwa kwezimbiwa.
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 ithoni ethile yemathiriyeli ngeyure.Ubuninzi bobuninzi obuncinane busetyenziswa ukumisela isantya, kwaye ubuninzi bobuninzi bobuninzi bumisela amandla (i-torque) efunwa 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 yokucheba licandelo elibalulekileyo kumiselo oluchanekileyo kunye nokukhethwa kwe-faskoti yesondlo kunye nenkqubo yokuqhuba (imoto). Kodwa iqiniseke njani? Ubude be-hopper yokucheba ngumlinganiselo osuka kwipleyiti ebhityisiweyo engasemva ukuya kwibar yokucheba kwindawo Isiphelo se-hopper.Kuvakala kulula, kodwa kubalulekile ukuqaphela ukuba oku akufuneki kubhideke kunye nobukhulu bomphezulu we-hopper ebambe izinto.
Injongo yokufumana lo mlinganiso wobude be-hopper kukuqinisekisa umgca wendiza yokucheba yeyona nto kwaye apho izinto ezikwi-skirt zihlula (i-shears) kwizinto eziphathekayo (L2) kwi-hopper.Ukumelana nokucheba kwezinto ngokuqhelekileyo kuqikelelwa. ibe phakathi kwe-50-70% yamandla ewonke/amandla.Olu balo lobude bokucheba luya kubangela nokuba kuphantsi kwamandla (ukulahlekelwa yimveliso) okanye ukongamela (ukwanda kweendleko zokusebenza (opex)).
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 bumiselwa njani ubude obona bude? Obona bude bufanelekileyo be-faskoti yesondlo bobo bunokuhlangabezana nomsebenzi ofunekayo kowona bude bufutshane bunokwenzeka. izinto eziphathekayo kwizixhobo ezisezantsi kunye nokuphelisa iindawo zokudlulisa (kunye neendleko ezingeyomfuneko).
Ukumisela i-feeder imfutshane kwaye ingcono kakhulu, i-apron feeder kufuneka ibekwe ngokuguquguqukayo phantsi kwe-hopper (L2) .Emva kokumisela ubude be-shear kunye nobunzulu bebhedi, ubude bubonke bunokuncitshiswa ukunqanda into ebizwa ngokuba "yi-self-flushing" ukuphela kokukhutshwa xa i-feeder ingasebenzi.
Ukukhetha inkqubo efanelekileyo yokuqhuba i-apron feeder yakho kuya kuxhomekeka ekusebenzeni kunye neenjongo ze-feeder.I-Apron Feeders yenzelwe ukusebenza ngesantya esiguquguqukayo ukukhupha kwindawo yokugcina kunye nokutya okusezantsi kwizinga elilawulwayo lokuphumelela okuphezulu.Izinto eziphathekayo zinokwahluka ngenxa yezinto njengexesha lonyaka, umzimba wentsimbi okanye uqhushumbo kunye neepateni zokuxuba.
Iindidi ezimbini zokuqhuba ezilungele isantya esiguquguqukayo ziidrive zoomatshini zisebenzisa i-gear reducers, ii-motor frequency frequency motors kunye ne-variable frequency drives (VFDs), okanye ii-motor hydraulic motors kunye neeyunithi zamandla ezineempompo zokufuduka eziguquguqukayo. ekhethwayo ngenxa yenkqubela phambili yetekhnoloji kunye neenzuzo zenkcitho enkulu.
Iinkqubo ze-hydraulic drive zinendawo yazo, kodwa azijongwa njengefanelekileyo phakathi kweedrive ezimbini eziguquguqukayo.
