Tichitevera kuburitswa kwechinyorwa chaGumiguru cheInternational Mining, uye kunyanya chiitiko chegore negore chekupwanya nekufambisa, takatarisisa chimwe chezvinhu zvakakosha zvinoumba masisitimu aya, apron feeder.
Mumugodhi,apron feederskuita basa rakakosha mukuona kushanda kwakanaka uye kuwedzera nguva. Maitiro avo mumamineral processing circuits akasiyana kwazvo; zvisinei, kugona kwavo kuzere hakuna kunyatsozivikanwa muindasitiri yese, zvichitungamira kune yakawanda yemibvunzo yakamutswa.
Martin Yester, Global Product Support, Metso Bulk Products, inopindura mimwe mibvunzo yakakosha.
Mumashoko akareruka, apron feeder (inozivikanwawo sepani yekudyisa) imhando yemakanika yekudyisa inoshandiswa mukubata zvinhu kuendesa (yekudyisa) zvinhu kune mimwe michina kana kubva mudura rekuchengetedza, bhokisi kana hopper kuburitsa zvinhu (ore/dombo) pamwero unodzorwa.
Aya mafeeder anogona kushandiswa mumhando dzakasiyana dzekushandisa mumabasa ekutanga, echipiri uye epamusoro (kudzoreredza).
Tractor chain apron feeders zvinoreva undercarriage cheni, rollers nemavhiri emuswe ayo anoshandiswawo pamabulldozers and excavators.Iyi mhando yefeeder inotonga maindasitiri umo vashandisi vanoda feeder inogona kuburitsa zvinhu zvine zvinhu zvakasiyana.Polyurethane seals in the chain inodzivirira abrasive material kuti asapinda mukati mapini uye mapini emukati uye anowedzera machira ekurerutsa chain, life reduction chain. mafeeders zvakare anoderedza kusvibiswa kweruzha kuitira kushanda kwakanyarara. Malink echeni anorapwa kupisa kwehupenyu hwakareba.
Pakazara, mabhenefiti anosanganisira kuwedzera kuvimbika, mashoma ezvimedu, mashoma kuchengetedza uye zvirinani kutonga kwekudya.Mukudzoka, zvikomborero izvi zvinowedzera kugadzirwa nemabhodhoro mashoma mune chero mineral processing loop.
Kutenda kwakafanana nezveapron feedersndezvokuti dzinofanira kuiswa zvakachinjika.Zvakanaka, zvinopesana nezvinotendwa nevakawanda, zvinogona kuiswa pamateru!Izvi zvinounza mamwe mabhenefiti akawanda uye maficha.Paunenge uchiisa apron feeder pamateru, nzvimbo shoma inodiwa zvachose - kwete chete kuti mutsetse unoganhura nzvimbo yepasi, inoderedzawo kureba kwekugamuchira hopper.Inotsvedza kune mamwe maapuroni, machuru anowedzera kune maapron mahombe, machuru anowedzera maapuroni, machuru anowedzera, machuru eapron anowedzera. vhoriyamu muhopper uye kuderedza nguva dzekutenderera kwemarori anotakura.
Ramba uchifunga kuti pane zvimwe zvinhu zvinofanirwa kucherechedzwa kana uchiisa pani yekudyisa pamateru kuti ugone kukwidziridza maitiro.Hopper yakagadzirwa nemazvo, angle yekurerekera, dhizaini yerutsigiro chimiro, uye hurongwa hwemavhesi uye masitepisi akatenderedza feeder zvese zvakakosha.
Mafungiro akajairika pamusoro pekushandisa chero mudziyo ndewekuti: "Nokukurumidza zviri nani."Kusvika kune apron feeders kuenda, hazvisi izvo.Optimal kumhanya kunobva pakuwana chiyero pakati pekushanda nekumhanya kwekutumira.Vanomhanya zvishoma pane mabhandi feeder, asi nechikonzero chakanaka.
Kazhinji, iyo yakakwana yekumhanya kweapron feeder ndeye 0.05-0.40 m / s. Kana iyo ore isingasviki, kukurumidza kunogona kuwedzerwa kusvika pamusoro pe 0.30 m / s nekuda kwekugona kuderedzwa kupfeka.
Kumhanya kwepamusoro kunokanganisa kushanda: kana kumhanya kwako kwakanyanyisa, iwe unoisa pangozi kukurumidza kupfeka pazvikamu.Kushanda kwesimba kunodererawo nekuda kwekuwedzera kwekuda kwesimba.
Imwe nyaya yekuchengeta mupfungwa paunenge uchimhanyisa apron feeder nekumhanya kwakanyanya ndeyekuwedzera mukana wefaindi.Panogona kunge paine abrasive mhedzisiro pakati pechinhu nendiro.Nekuda kwekuvapo kweguruva rinotiza mumhepo, kusikwa kwefaindi hakukonzeri matambudziko mazhinji chete, asiwo kunogadzira nzvimbo yebasa ine ngozi kune vashandi vese.Saka, kuwana iyo optimum kukurumidza kukurumidza kwechirimwa kunonyanya kukosha kune kuchengetedzwa kwechirimwa nekukurumidza.
MaApron feeder ane zvaasingakwanisi kana zvasvika pakukura nerudzi rweore. Zvirambidzo zvichasiyana, asi zvinhu hazvifanire kukandwa zvisina musoro pamudyo. Haufanire kufunga nezve application chete yauchashandisa iyo yekudyisa, asiwo kuti iyo feeder ichaiswa kupi mukuita.
Muzhinji, mutemo weindasitiri weapron feeder saizi yekutevera ndeyekuti hupamhi hwepani (yemukati siketi) inofanira kunge yakapetwa kaviri saizi yechinhu chikuru chechinhu.Zvimwe zvikonzero, senge hopper yakavhurika yakanyatsogadzirirwa yakabatanidzwa nekushandiswa kwe "rock flip plate", inogona kukanganisa pani saizi, asi izvi zvinongoenderana mune mamwe mamiriro ezvinhu.
Hazvishamisi kukwanisa kubvisa 1,500mm yezvinhu kana 3,000mm yakafara feeder inoshandiswa.Negative 300mm zvinhu zvakabviswa kubva kucrusher ore piles kana kuchengetedza / kusanganisa mabhokisi anowanzo kutorwa achishandisa apron feeder kuti adyise yechipiri crusher.
Paunenge uchiisa saizi yeapron feeder uye inoenderana nedhiraivha system (motor), sezvimedu zvakawanda zvemidziyo muindasitiri yezvicherwa, ruzivo uye ruzivo rwemaitiro ese akakosha.Apron feeder sizing inoda ruzivo rwekutanga rwe data refekitori kuti rizadze nemazvo maitiro anodiwa nemupi we "Application Data Sheet" (kana kuti mutengesi anogamuchira ruzivo rwavo).
Mamiriro ekutanga anofanirwa kutariswa anosanganisira chiyero chekudya (peak uye zvakajairika), zvinhu zvemukati (senge mwando, gradation uye chimiro), yakakura block saizi yeore / dombo, kuwanda kwehuwandu hweore / dombo (yakanyanya uye shoma) uye chikafu uye Outlet mamiriro.
Zvisinei, dzimwe nguva zvinosiyana zvinogona kuwedzerwa kuapron feeder sizeing process iyo inofanirwa kusanganisirwa.Chikuru chekuwedzera chinosiyana icho vatengesi vanofanira kubvunza nezve hopper configuration.Kunyanya, hopper cut length yekuvhura (L2) inowanikwa zvakananga pamusoro peapron feeder.Pazvinoshanda, iyi ndiyo parameter yakakosha kwete yekuyera nemazvo apron feeder system, asiwo yeapron feeder system.
Sezvataurwa pamusoro apa, kuwanda kwehuwandu hwematombo / dombo ndechimwe chezvinhu zvakakosha zvinodiwa uye zvinofanirwa kusanganisira zvinobudirira hoarding feeder size.Density uremu hwechinhu muvhoriyamu yakapihwa, kazhinji kuwanda kwehuwandu hunoyerwa mumatani pa cubic mita (t/m³) kana pounds per cubic foot (lbs/ft³) . density senge mune mamwe mamineral processing equipment.
Saka sei bulk density yakakosha kudaro?Apron feeder are volumetric feeders, zvinoreva kuti bulk density inoshandiswa kuona kukurumidza uye simba rinodiwa kubvisa imwe tonnage yezvinhu paawa.Iyo shoma yehuwandu hwehuwandu hunoshandiswa kuona kukurumidza, uye huwandu hwehuwandu hwehuwandu hunogadzirisa simba (torque) rinodiwa neanodyisa.
Zvose mune zvose, zvakakosha kushandisa "huwandu" hwakarurama "huwandu" panzvimbo ye "yakasimba" density kuti uwedzere apron feeder yako.Kana izvi zviverengero zvisina kururama, chiyero chekupedzisira chekudya kwemaitiro ezasi chinogona kukanganisa.
Kuziva kureba kwehopper shear chinhu chakakosha mukutsunga uye kusarudzwa kweapron feeder uye drive system (motor) .Asi izvi zvine chokwadi sei?Hopper shear kureba ndiyo dimension kubva kune skirted hopper yekumashure ndiro kusvika kune shear bar kumucheto kwekubuda kwehopper.Zvinonzwika zviri nyore, asi zvakakosha kuziva kuti izvi hazvifanirwe kuvhiringidzwa nepamusoro peiyo hopper.
Chinangwa chekutsvaga iyi hopper shear kureba kuyerwa ndeyekuona iyo chaiyo shear plane mutsara wezvinhu uye apo zvinhu zviri mujasi zvinopatsanura (shears) kubva kune zvinhu (L2) muhopper.Kuveura kweshear kwechigadzirwa kunowanzofungidzirwa kuva pakati pe50-70% yesimba rose.Ichi chiverengero chehurefu hweshear chinozoguma nekuve underpower (shear) kubva kune zvinhu (L2) mune hopper.Kuveura kweshear kwechinhu kunowanzofungidzirwa kuva pakati pe50-70% yehuwandu hwesimba/simba.Ichi chiverengero chehurefu hweshear chinozoguma nekuve underpower (shear) kubva kune zvinhu (L2) muhopi.
Equipment spacing inokosha kune chero chirimwa.Sezvakataurwa kare, apron feeder inogona kuiswa pamateru kuchengetedza nzvimbo.Kusarudza urefu hwakarurama hweapron feeder haigoni kuderedza kushandiswa kwemari (capex), asiwo kuderedza kushandiswa kwesimba uye kushandiswa kwemari.
Asi hurefu hwakakwana hunotsanangurwa sei?Kureba kwakakwana kweapron feeder ndiyo inogona kusangana nebasa rinodiwa muhurefu hupfupi.Zvisinei, mune dzimwe nguva, nokuda kwebasa, kusarudzwa kwemafuro kunogona kutora nguva yakareba "kutamisa" zvinhu kumidziyo yepasi uye kubvisa nzvimbo dzekufambisa (uye mari isingakoshi).
Kuti uone kupfupika uye kwakanakisisa kunogoneka kudyisa, iyo apron feeder inoda kuiswa zvakanaka pasi pehopper (L2) .Mushure mekusarudza kureba kweshear uye kudzika kwemubhedha, kureba kwese kunogona kuderedzwa kudzivirira izvo zvinonzi "self-flushing" pakupera kwekubuda apo mufudzi asingabatsiri.
Kusarudza nzira yekufambisa yeapron feeder yako ichaenderana nekushanda uye zvinangwa zvechifukidzo.Apron Feeders dzakagadzirirwa kushanda nekumhanya kwakasiyana-siyana kubvisa kubva mukuchengetedza uye kudyisa pasi pemvura inodzorwa kuti ibudirire zvakanyanya.Zvinhu zvinogona kusiyana nekuda kwezvinhu zvakadai semwaka wegore, ore muviri kana kuputika uye kusanganisa maitiro.
Mhando mbiri dzemadhiraivha akakodzera kuchinjika kumhanya ndiwo madhiraivha emagetsi anoshandisa magiya ekudzikisa, madhiraivha emagetsi uye madhiraivha madhiraivha (VFDs), kana ma hydraulic motors uye magetsi mayuniti ane mapombi anochinja-chinja.
Hydraulic drive masisitimu ane nzvimbo yawo, asi haaonekwe seakanaka pakati pemadhiraivha maviri akasiyana.
