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 omwe amagwiritsidwa ntchito poyendetsa zinthu kutumiza (chakudya) zinthu kupita ku zida zina kapena kuchokera kuzinthu zosungirako, bokosi kapena hopper kuti achotse zinthu (ore/rock) pamlingo woyendetsedwa.
Ma feed awa atha kugwiritsidwa ntchito m'njira zosiyanasiyana m'machitidwe a pulaimale, sekondale ndi apamwamba (kuchira).
Tractor chain apron feeders amatanthawuza maunyolo apansi, odzigudubuza ndi mawilo amchira omwe amagwiritsidwanso ntchito pa bulldozers ndi zofukula. Mtundu uwu wa feeder umayang'anira mafakitale omwe ogwiritsa ntchito amafunikira chakudya chomwe chimatha kuchotsa zinthu zokhala ndi katundu wosiyana.Zisindikizo za polyurethane mu unyolo zimalepheretsa zinthu zowonongeka kuti zilowe m'mapini amkati ndi ma tcheni owuma poyerekeza ndi ma tcheni owumitsa a tractor ndi kukulitsa moyo wa tractor. ma feeders amachepetsanso kuyipitsa kwa phokoso kuti agwire ntchito mosadukiza.Malumikizidwe a unyolo amatenthedwa 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 feedersChabwino, mosiyana ndi zomwe anthu ambiri amakhulupirira, akhoza kukwera pamapiri! Izi zimabweretsa zopindulitsa zambiri zowonjezera ndi zina. Mukaika apron feeder pamtunda wotsetsereka, malo ocheperako amafunikira ponseponse - osati kokha kuti malo otsetsereka amachepetsa malo apansi, amachepetsanso kutalika kwa hopper yolandira. kuchuluka kwa hopper ndikuchepetsa nthawi yozungulira pamagalimoto onyamula.
Kumbukirani kuti pali zinthu zina zomwe muyenera kuzidziwa mukayika poto wodyetsa pamtunda kuti muwongolere bwino ndondomekoyi. Hopper yokonzedwa bwino, angle of inclination, mapangidwe a dongosolo lothandizira, ndi dongosolo la ndime ndi masitepe ozungulira chodyera ndi zinthu zofunika kwambiri.
Malingaliro olakwika odziwika bwino okhudza kugwiritsa ntchito chipangizo chilichonse ndi: "Mwamsanga zimakhala bwino."Monga momwe ma apron feeders amapita, sizili choncho.Liwiro labwino kwambiri limachokera pakupeza kulinganiza pakati pa kuchita bwino ndi liwiro la kutumiza.Amathamanga pang'onopang'ono kuposa odyetsa lamba, koma pazifukwa zomveka.
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 ndi kuchuluka kwa chiwongoladzanja.Pakhoza kukhala zotsatira zowonongeka pakati pa zinthu ndi mbale. Chifukwa cha kupezeka kwa fumbi lothawirako mumlengalenga, kupanga chindapusa sikungoyambitsa mavuto ambiri, komanso kumapanga malo owopsa kwambiri ogwira ntchito kwa antchito onse.
Ma apron feeders ali ndi malire pankhani ya kukula ndi mtundu wa ore.Zoletsa zimasiyana, koma zinthu siziyenera kutayidwa mopanda tanthauzo pachopha.Simuyenera kuganizira kokha kugwiritsa ntchito komwe mudzagwiritse ntchito chodyetsa, komanso komwe chakudyacho chidzayikidwa munjira.
Kawirikawiri, lamulo la mafakitale la kukula kwa apron feeder kuti litsatire ndiloti m'lifupi mwake (siketi yamkati) iyenera kukhala yowirikiza kawiri kukula kwa chinthu chachikulu kwambiri.Zinthu zina, monga hopper yotseguka yopangidwa bwino pamodzi ndi ntchito ya "rock flip plate", ingakhudze kukula kwa poto, koma izi ndizofunikira pazochitika 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.
Mukamapanga ma apron feeder ndi ma drive system (motor), monga momwe zilili ndi zida zambiri m'makampani amigodi, chidziwitso ndi chidziwitso cha njira yonseyi ndi zamtengo wapatali.Apron feeder sizing imafuna chidziwitso choyambirira cha data ya fakitale kuti mudzaze molondola njira zomwe zimafunidwa ndi "Application Data Sheet" (kapena wopereka amalandira zidziwitso zawo).
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 ore / thanthwe (kuchuluka ndi kuchepera) ndi chakudya ndi malo ogulitsa.
Komabe, nthawi zina zosinthika zitha kuwonjezeredwa ku njira yopangira apron feeder sizing yomwe ikuyenera kuphatikizidwa. Kusintha kwakukulu kowonjezera komwe ogulitsa akuyenera kufunsa ndikusintha kwa hopper.Mwachindunji, kutsegula kwakutali kwa hopper (L2) kumakhala pamwamba pa apron feeder. Pomwe kuli kotheka, iyi ndi gawo lofunikira osati pakuyesa molondola kwa apron feeder, komanso pamakina oyendetsa.
Monga tafotokozera pamwambapa, kachulukidwe kachulukidwe ka ore/thanthwe ndi chimodzi mwazofunikira zomwe zimayenera kuphatikizira kukula kosungirako bwino kwa chakudya. kachulukidwe ngati zida zina zopangira mchere.
Nanga nchifukwa chiyani kuchulukana kwakukulu kuli kofunika kwambiri? Ma apron feeders ndi ma volumetric feeder, zomwe zikutanthauza kuti kachulukidwe kachulukidwe kameneka amagwiritsidwa ntchito kuti adziwe liwiro ndi mphamvu zomwe zimafunikira kutulutsa matani ena azinthu pa ola.Kuchulukira kochepa kwambiri kumagwiritsidwa ntchito kudziwa liwiro, ndipo kuchuluka kwachulukidwe kochuluka kumatsimikizira mphamvu (torque) yofunidwa ndi wodyetsa.
Zonsezi, ndikofunikira kugwiritsa ntchito kachulukidwe kolondola ka "zochuluka" m'malo "olimba" kachulukidwe kuti kukula kwa apron feeder.Ngati mawerengedwewa ali olakwika, kuchuluka kwa chakudya chomaliza cha njira yakutsika kumatha kusokonezedwa.
Kudziwa kutalika kukameta ubweya wa hopper ndi gawo lofunikira pakutsimikiza kolondola ndi kusankha kwa aproni feeder ndi drive system (motor). Koma izi ndi zowona bwanji? Hopper shear kutalika ndi gawo lochokera ku siketi yokhotakhota kumbuyo kwa mbale yometa ubweya kumapeto kotulukira kwa hopper. Zikumveka zosavuta, koma ndikofunikira kuzindikira kuti izi siziyenera kusokonezedwa ndi nsonga zapamwamba za hopper.
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) kuchokera ku zinthu (L2) mu hopper.
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 apron feeder ndi komwe kungathe kukwaniritsa ntchito yofunikira muutali waufupi kwambiri.
Kuti mudziwe chakudya chachifupi kwambiri komanso chotheka, chodyetsa cha apron chiyenera kukhazikitsidwa mosinthasintha pansi pa hopper (L2) . Pambuyo pozindikira kutalika kwa kukameta ubweya ndi kuya kwa bedi, utali wonse ukhoza kuchepetsedwa kuti muteteze zomwe zimatchedwa "kudzidzidzimutsa" kumapeto kwa kutulutsa pamene wodyetsa alibe ntchito.
Kusankha dongosolo loyendetsa bwino la apron feeder yanu kudzadalira ntchito ndi zolinga za feeder.Apron Feeders amapangidwa kuti azigwira ntchito mofulumira kuti atenge kuchokera kusungirako ndi kudyetsa kunsi kwa mtsinje pa mlingo wolamulidwa kuti azichita bwino kwambiri.Zinthu 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 makina ogwiritsira ntchito zida zochepetsera, ma frequency motors ndi ma frequency frequency drives (VFDs), kapena ma hydraulic motors ndi magawo amagetsi okhala ndi mapampu osinthira.
Makina oyendetsa ma hydraulic ali ndi malo awo, koma samawonedwa ngati abwino pakati pa ma drive awiri osinthika.
