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 dzakachinjika.Zvakanaka, zvinopesana nezvinodavirwa nevakawanda, dzinogona kuiswa pamateru!Izvi zvinounza zvimwe zvakawanda zvinobatsira uye maficha.Pakuisa apuroni feeder pamateru, nzvimbo shoma inodiwa zvachose - kwete chete kutsetseka. kuderedza nzvimbo yepasi, inoderedzawo kureba kwekugamuchira hopper.Sloping apron feeders inonyanya kukanganwira kana zvasvika kune machunks makuru ezvinyorwa uye, zvakazara, zvichawedzera vhoriyamu muhopi uye kuderedza kutenderera nguva dzekutakura marori.
Ramba uchifunga kuti pane zvimwe zvinhu zvinofanirwa kucherechedzwa kana uchiisa pani yekudyisa pamateru kuti ukwidzise maitiro.Hopper yakagadzirwa nemazvo, angle yekurerekera, dhizaini yerutsigiro chimiro, uye hurongwa hwemafashama nemasitepisi akatenderedza feeder. zvose zvinhu zvinokosha.
Mafungiro akajairika pamusoro pekushandisa chero mudziyo ndewekuti: "Kukurumidza kuita zvirinani."Kusvika pakuenda apron feeders, hazvisizvo.Optimal speed inobva pakuwana chiyero pakati pekushanda nekumhanya kwekutumira.Idzo dzinomhanya zvishoma kudarika mabhandi ekudyisa, 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 pezvinhu neplate.Nekuda kwekuvapo kwekuvapo kweguruva rekutiza mumhepo, kusikwa kwefaindi kwete. zvinongogadzira mamwe matambudziko, asiwo zvinogadzira nzvimbo yebasa ine ngozi kune vashandi pamwe chete.Saka, kutsvaga kukurumidza kwakanyanya kunotonyanya kukosha pakubudirira kwezvirimwa uye kuchengetedzwa kwekushanda.
MaApron feeder ane zvaasingakwanisi kana zvasvika pakukura nerudzi rweore. Zvirambidzo zvichasiyana, asi zvinhu hazvifanirwe kukandwa zvisina basa pamufidha. Haufanire kufunga nezve application chete yauchashandisa iyo yekudyisa, asiwo kuti feeder ichaiswa mukuita.
Kazhinji, mutemo weindasitiri weapuroni feeder saizi yekutevera ndeyekuti hupamhi hwepani (yemukati siketi) inofanira kunge yakapetwa kaviri saizi yechinhu chikuru chechinhu.Zvimwe zvikonzero, senge hopper yakavhurika yakagadzirwa nemazvo yakasanganiswa nekushandiswa kwe "rock flip plate", inogona kukanganisa saizi yepani, asi izvi zvinongoenderana mune mamwe mamiriro.
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 drive system (motor), sezvimedu zvakawanda zvemidziyo muindasitiri yezvicherwa, ruzivo uye ruzivo rwemaitiro ese akakosha.Apron feeder sizing inoda ruzivo rwekutanga rwe data refekitori kuzadza nemazvo maitiro. inodiwa nemutengesi "Application Data Sheet" (kana kuti mutengesi anogamuchira ruzivo rwavo).
Maitiro ekutanga anofanirwa kutariswa anosanganisira chiyero chekudya (peak uye chakajairwa), zvinhu zvemukati (senge mwando, gradation uye chimiro), yakakura block saizi yeore / dombo, kuwanda kwehuremu hweore / dombo (yakakura uye shoma) uye chikafu uye Outlet. mamiriro.
Zvisinei, dzimwe nguva zvinosiyana zvinogona kuwedzerwa kuapron feeder sizeing process iyo inofanira kusanganisirwa.Chimwe chikuru chekuwedzera icho vatengesi vanofanira kubvunza nezvacho ndechekugadzirisa hopper.Kunyanya, hopper cut length kuvhura (L2) inowanikwa kumusoro kweapron feeder. inoshanda, iyi ndiyo parameter yakakosha kwete chete yekuenzanisa apron feeder, asiwo yedhiraivha system.
Sezvambotaurwa pamusoro apa, kuwanda kwesimbi yematombo/dombo ndechimwe chezvinhu zvinokosha zvinodiwa uye kunofanira kusanganisira hukuru hwekudyisa. Density uremu hwechinhu chiri muvhoriyamu yakapihwa, kazhinji huzhinji huzhinji hunoyerwa mumatani pa cubic meter (t. /m³) kana makirogiramu pa cubic foot (lbs/ft³). Chinhu chakakosha kuchengeta mupfungwa ndechekuti kuwanda kwehuwandu hunoshandiswa pakudyisa maapron, kwete kusimba kwezvakaoma sezvinoitwa mune mamwe mamineral processing equipment.
Saka sei bulk density yakakosha kudaro?Apron feeder are volumetric feeders, zvinoreva kuti bulk density inoshandiswa kuona kumhanya uye simba rinodiwa kuburitsa imwe tonnage yezvinhu paawa.Iyo shoma yakawanda density inoshandiswa kuona kumhanya, uye iyo yakanyanya kuwanda density inosarudza simba (torque) inodiwa 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 zvinonyatsoita sei?Hopper shear kureba ndiyo dimension kubva kune skirted hopper back plate kusvika pa shear bar pa kuguma kwekubuda kwehopper.Zvinonzwika zviri nyore, asi chakakosha kuziva kuti izvi hazvifanirwe kuvhiringika nehukuru hwepamusoro wehopper inobata zvinhu.
Chinangwa chekutsvaga iyi hopper shear urefu hwekuyera ndeyekuona iyo chaiyo yekuveura ndege mutsara wezvinhu uye apo zvinhu zviri mupendero zvinoparadzanisa (shears) kubva kune zvinhu (L2) muhopi. kuva pakati pe50-70% yehuwandu hwesimba / simba.Iyi kuverengwa kwehurefu hweshear kuchaita kuti zvive pasi pesimba (kurasikirwa kwekugadzirwa) kana kudarika (kuwedzera kwekushandisa mari (opex)).
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 hunotariswa sei? Hurefu hwakakwana hweapron feeder ndehuya hunogona kusangana nebasa rinodiwa muhurefu hupfupi.Zvisinei, mune dzimwe nguva, pakuvhiya, sarudzo yekudyisa inogona kutora nguva yakareba "kutamisa" zvinhu kumidziyo yepasi uye kubvisa nzvimbo dzekufambisa (uye mari isingakoshi).
Kuti uone kupfupika uye kwakanakisisa kunogoneka kudyisa, apron feeder inoda kuiswa zvakanaka pasi pehopper (L2) .Mushure mekutarisa kureba kweshear nekudzika kwemubhedha, kureba kwese kunogona kuderedzwa kudzivirira izvo zvinonzi "self-flushing" pa. kubuda kunopera kana feeder isingaite.
Kusarudza dhiraivha yakanaka yeapron feeder yako zvinoenderana nekushanda uye zvinangwa zvemudyi.Apron Feeders dzakagadzirirwa kushanda nekumhanya kwakasiyana-siyana kubvisa kubva mukuchengetedza uye kudyisa kudzika kwerwizi pamwero wakadzorwa wekushanda kwakanyanya.Zvishandiso zvinogona kusiyana nekuda kwezvinhu. semwaka wegore, muviri wesimbi kana kuputika nekusanganisa mapatani.
Mhando mbiri dzemadhiraivha akakodzera kuchinjika kumhanya madhiraivha anoshandisa magiya ekudzikisa, madhiraivha emagetsi uye madhiraivha madhiraivha (VFDs), kana ma hydraulic motors nemayunitsi emagetsi ane mapombi anochinja-chinja. yesarudzo nekuda kwekufambira mberi kwetekinoroji uye mabhenefiti ekushandisa mari.
Hydraulic drive masisitimu ane nzvimbo yawo, asi haaonekwe seakanaka pakati pemadhiraivha maviri akasiyana.
