Kutsatira kusindikizidwa kwa magazini ya October ya International Mining, makamaka makamaka chaka chapachaka chophwanyidwa ndi kutumiza, tinayang'anitsitsa chimodzi mwazinthu zazikulu zomwe zimapanga machitidwewa, apron feeder.
Mu migodi,apuloni feederszimagwira ntchito yofunikira pakuwonetsetsa kuti zikuyenda bwino ndikuwonjezera nthawi.Ntchito zawo m'mabwalo opangira mchere ndizosiyana kwambiri;komabe, kuthekera kwawo kwathunthu sikudziwika bwino pamakampani onse, zomwe zimatsogolera ku mafunso ambiri omwe adafunsidwa.
Martin Yester, Global Product Support, Metso Bulk Products, amayankha ena mwa mafunso ofunika kwambiri.
M'mawu osavuta, apron feeder (yomwe imadziwikanso kuti pan feeder) ndi mtundu wamakina wa feeder womwe umagwiritsidwa ntchito posamalira zinthu kusamutsa (chakudya) zinthu kupita ku zida zina kapena kuchokera pazosungirako, bokosi kapena hopper kuti mutenge zinthu (ore/rock). ) pamlingo wolamulidwa.
Ma feed awa atha kugwiritsidwa ntchito m'njira zosiyanasiyana m'machitidwe a pulaimale, sekondale ndi apamwamba (kuchira).
Ma thirakitala chain apron feeders amanena za maunyolo apansi, zogudubuza ndi magudumu amchira omwe amagwiritsidwanso ntchito pa bulldozers ndi excavators. Mtundu uwu wa feeder umayang'anira mafakitale omwe ogwiritsa ntchito amafunikira feeder yomwe imatha kutulutsa zinthu zosiyanasiyana.Zisindikizo za polyurethane mu unyolo zimateteza zinthu zowononga kulowa m'mapini amkati ndi tchire, kuchepetsa kuvala ndi kukulitsa moyo wa zida poyerekeza ndi maunyolo owuma.Odyetsa apuloni a thirakitala amachepetsanso kuipitsidwa kwa phokoso kuti agwire ntchito mopanda phokoso.Malumikizidwe a unyolo amathandizidwa ndi kutentha kwa moyo wautali.
Ponseponse, zopindulitsa zimaphatikizapo kudalirika kowonjezereka, zotsalira zochepa, kusamalidwa pang'ono komanso kuwongolera bwino chakudya.Pobweza, zopindulitsazi zimawonjezera zokolola ndi zopinga zochepa mu loop iliyonse yopangira mchere.
Chikhulupiriro wamba zaapuloni feedersndiye kuti ziyenera kuyikidwa mopingasa.Chabwino, mosiyana ndi zomwe anthu ambiri amakhulupirira, zimatha kuyikidwa pamapiri!Izi zimabweretsa maubwino owonjezera ndi zinthu zina.Mukayika chodyera cha apuloni pamalo otsetsereka, malo ochepera amafunikira ponseponse - osati otsetsereka kokha. kuchepetsa malo apansi, kumachepetsanso kutalika kwa cholandirira cholandirira. Okhotakhota apuloni odyetsa amakhala okhululuka akafika pamagulu akuluakulu azinthu ndipo, ponseponse, adzawonjezera kuchuluka kwa hopper ndikuchepetsa nthawi yozungulira pamagalimoto onyamula katundu.
Kumbukirani kuti pali zinthu zina zomwe muyenera kuzidziwa mukayika chowotcha poto pamalo otsetsereka kuti muwongolere bwino ntchitoyo. Chophimba chopangidwa bwino, ngodya yamalingaliro, kapangidwe kakapangidwe ka chithandizo, komanso njira yolowera ndi masitepe mozungulira chodyera. zonse ndi zinthu zofunika.
Malingaliro olakwika odziwika bwino okhudza kugwiritsa ntchito chipangizo chilichonse ndi: "Posachedwa kuchita bwino."Pamene ma apron feeders amapita, sizili choncho.Liwiro labwino kwambiri limabwera chifukwa chopeza bwino pakati pa magwiridwe antchito ndi liwiro la kutumiza.Amayenda pang'onopang'ono kuposa odyetsa lamba, koma pazifukwa zabwino.
Kawirikawiri, liwiro labwino kwambiri la apron feeder ndi 0.05-0.40 m / s. Ngati ore sakuwonongeka, liwiro likhoza kuwonjezeka kufika pamwamba pa 0,30 m / s chifukwa cha kuchepa kwachangu.
Kuthamanga kwapamwamba kumawononga ntchito: ngati kuthamanga kwanu kuli kwakukulu, mumakhala pachiwopsezo chofulumira kuvala pazinthu zamagulu.
Chinthu china choyenera kukumbukira pamene mukuyendetsa apron feeder pa liwiro lalikulu ndikuwonjezereka kwa chiwongoladzanja.Pakhoza kukhala zotsatira zowonongeka pakati pa zinthu ndi mbale. zimangoyambitsa mavuto ochulukirapo, komanso zimapanga malo ogwirira ntchito owopsa kwa antchito onse.Chifukwa chake, kupeza liwiro lokwanira ndikofunikira kwambiri pakupanga zokolola komanso chitetezo chogwira ntchito.
Ma apron feeder ali ndi malire pankhani ya kukula ndi mtundu wa ore. Zoletsa zimasiyana, koma zinthu siziyenera kutayidwa mopanda pake pa chodyetsa. feeder idzayikidwa mu ndondomekoyi.
Nthawi zambiri, lamulo lamakampani la kukula kwa aproni feeder kuti litsatire ndikuti m'lifupi mwake poto (siketi yamkati) iyenera kuwirikiza kawiri kukula kwa chinthu chachikulu kwambiri.Zinthu zina, monga hopper yotseguka yopangidwa bwino kuphatikiza kugwiritsa ntchito "rock flip plate", ingakhudze kukula kwa poto, koma izi ndizofunikira muzochitika zina.
Si zachilendo kuti mutha kutulutsa zinthu za 1,500mm ngati chowonjezera cha 3,000mm chachikulu chikugwiritsidwa ntchito.Zoyipa za 300mm zomwe zimachotsedwa ku milu ya ore crusher kapena mabokosi osungira / osakaniza amachotsedwa pogwiritsa ntchito apron feeder kudyetsa chopondapo chachiwiri.
Mukamayesa apron feeder ndi drive drive system (motor), monga momwe zilili ndi zida zambiri m'makampani amigodi, chidziwitso ndi chidziwitso cha ntchito yonseyi ndi zamtengo wapatali.Apron feeder sizing imafunikira chidziwitso choyambirira cha data ya fakitale kuti mudzaze molondola zomwe mukufuna. zofunidwa ndi "Application Data Sheet" (kapena wogulitsa amalandira zambiri).
Zofunikira zomwe ziyenera kuganiziridwa ndi monga kuchuluka kwa chakudya (chapamwamba ndi chachilendo), katundu wakuthupi (monga chinyezi, kusinthasintha ndi mawonekedwe), kukula kwa chipilala cha ore / thanthwe, kuchulukitsitsa kwa miyala / miyala (kuchuluka ndi kuchepera) ndi chakudya ndi Outlet. mikhalidwe.
Komabe, nthawi zina zosinthika zitha kuwonjezeredwa ku njira yopangira ma apron feeder sizing yomwe ikuyenera kuphatikizidwa.Kusintha kwakukulu kowonjezera komwe ogulitsa ayenera kufunsa ndikusintha kwa hopper.Mwachindunji, kutsegula kwakutali kwa hopper (L2) kumakhala pamwamba pa apron feeder. imagwira ntchito, iyi ndi gawo lofunikira osati kungoyesa moyenera apron feeder, komanso pama drive system.
Monga tafotokozera pamwambapa, kachulukidwe kachulukidwe ka miyala/mwala ndi chimodzi mwa zinthu zofunika kwambiri ndipo kuyenera kuphatikizirapo kukula kwa kachulukidwe ka chuma. /m³) kapena ma pounds pa kiyubiki phazi (lbs/ft³). Chodziwika chapadera choyenera kukumbukira ndi chakuti kuchulukana kwakukulu kumagwiritsidwa ntchito pa ma apron feeders, osati kachulukidwe kolimba monga m'zida zina zopangira mchere.
Nanga n’chifukwa chiyani kachulukidwe kachulukidwe n’kofunika kwambiri? Ma apron feeders ndi ma volumetric feeders, kutanthauza kuti kachulukidwe kachulukidwe kamene kakugwiritsidwa ntchito pozindikira liwiro ndi mphamvu zomwe zimafunika kuti zichotse matani enaake a zinthu pa ola. kuchulukirachulukira kwakukulu kumatsimikizira mphamvu (torque) yofunikira ndi wodyetsa.
Zonsezi, ndikofunika kugwiritsa ntchito kachulukidwe kolondola ka "zochuluka" m'malo "olimba" kachulukidwe kuti kukula kwa apron feeder.Ngati mawerengedwewa ali olakwika, mlingo womaliza wa chakudya chamtsinje ukhoza kusokonezeka.
Kuzindikira kutalika kwa kukameta ubweya wa hopper ndi gawo lofunikira pakutsimikiza koyenera ndi kusankha kwa aproni feeder ndi drive system (motor). Koma izi ndi zowona bwanji? Utali wa kumeta ubweya wa Hopper ndi gawo lochokera ku mbale yakumbuyo ya siketi mpaka kukameta ubweya ku bar Kutuluka kumapeto kwa hopper.Zikumveka zosavuta, koma ndikofunikira kuzindikira kuti izi siziyenera kusokonezedwa ndi kukula kwa pamwamba pa hopper yomwe imagwira zinthuzo.
Cholinga chopezera muyeso wa kutalika kwa kumeta ubweya wa hopper ndikuzindikira mzere weniweni wa ndeke ya zinthuzo komanso komwe zinthu zomwe zili mu siketi zimalekanitsa (masheya) ndi zinthu (L2) mu hopper. kukhala pakati pa 50-70% ya mphamvu zonse / mphamvu.Kuwerengera kwa kutalika kwa shear kudzapangitsa kuti mukhale ndi mphamvu zochepa (kutaya kwa kupanga) kapena kugonjetsa (kuwonjezeka kwa ndalama zogwiritsira ntchito (opex)).
Kutalikirana kwa zida ndikofunikira kwa chomera chilichonse.Monga tafotokozera kale, chopereka cha apron chikhoza kukwera pamtunda kuti chiteteze malo.Kusankha kutalika koyenera kwa apron feeder sikungangochepetse ndalama zamtengo wapatali (capex), komanso kuchepetsa kugwiritsa ntchito mphamvu ndi ndalama zogwiritsira ntchito.
Koma kutalika kwake koyenera kumatsimikiziridwa bwanji? Kutalika koyenera kwa chophatikizira cha apuloni ndi komwe kungathe kukwaniritsa ntchito yofunikira muutali waufupi kwambiri. zakuthupi ku zida zotsika ndikuchotsa malo osinthira (ndi ndalama zosafunikira).
Kuti mudziwe chodyetsa chachifupi kwambiri komanso chabwino kwambiri, chodyera cha apron chiyenera kukhazikitsidwa mosinthasintha pansi pa hopper (L2) . Pambuyo pozindikira kutalika kwa shear ndi kuya kwa bedi, kutalika konseko kungathe kuchepetsedwa kuti muteteze zomwe zimatchedwa "kudzidzidzimutsa" pa. kutulutsa kumatha pamene chodyetsa sichigwira ntchito.
Kusankha dongosolo loyendetsa bwino la apron feeder yanu kudzadalira ntchito ndi zolinga za feeder.Apron Feeders amapangidwa kuti azigwira ntchito pa liwiro losiyana kuti atenge kuchokera kusungirako ndi kudyetsa pansi pamtsinje pa mlingo wolamulidwa kuti ukhale wogwira mtima kwambiri.Zida zikhoza kusiyana chifukwa cha zinthu. monga nyengo ya chaka, thupi la ore kapena kuphulika ndi kusakaniza machitidwe.
Mitundu iwiri ya ma drive omwe ali oyenera kuthamanga kosinthika ndi makina oyendetsa ma giya ochepetsa, ma frequency motors ndi ma frequency frequency drives (VFDs), kapena ma hydraulic motors ndi mayunitsi amagetsi okhala ndi mapampu osuntha. zosankhidwa chifukwa cha kupita patsogolo kwaukadaulo komanso kupindula kwa ndalama zazikulu.
Makina oyendetsa ma hydraulic ali ndi malo awo, koma samawonedwa ngati abwino pakati pa ma drive awiri osinthika.
