Covapron feeder muagyog tsim thiab tsim los ntawm lawv cov neeg siv khoom txawv teb chaws. Lub apron feeder rau muag yog nruab nrog PX1400/170 hydraulic crusher rau kev lag luam mining. Vim yog qhov tsis zoo ntawm cov qauv tsim qauv, cov saw hlau feem ntau elongated thiab poob rau hauv kev xyaum ntau lawm, uas yog ib qho yooj yim rau scrape down lub mine leakage nozzle, ua rau cov khoom siv tsis tu ncua thiab tsis ua hauj lwm, thiab nws yog ib qho nyuaj rau overhaul cov cuab yeej thaum lub xyoo kho los yog kho thiab hloov cov saw phaj, yog li nws yuav tsum tau kho dua tshiab. Yog li cov neeg siv khoom tuaj rau peb thiab thov kom peb muab lawv nrog kev kho dua tshiab.
Lub feeder yog powered los ntawm lub planetary reducer thiab ib tug khub ntawm qhib iav, thiab cov saw phaj tig nyob rau hauv lub tsav ntawm lub ntsiab tsav log. Cov ore ntog mus rau tom qab ntawm lub apron feeder saw phaj tom qab tawg los ntawm PX1400/170 hydraulic crusher, thiab lub rear ore yog thauj mus rau pem hauv ntej los ntawm lub apron feeder. Tom qab ntawd nws ntog mus rau lub tshuab siv los ntawm lub qhov dej ntws tawm thiab xa mus rau cov txheej txheem tom ntej 2. Kev pub mis me me ntawm apron feeder yog tsawg dua 350mm, lub peev xwm ntau lawm yog 1300 ~ 1800 / h, lub cev muaj zog yog 150kW, lub reducer yog NGW hom planetary reducer, thiab qhov sib kis ntawm 6.7 .3. Tag nrho cov saw phaj yog tsim los ntawm 58 daim ntawm ntses nplai phaj. Cov saw phaj yog tsav los ntawm lub ntsiab tsav lub hnub qub log. Cov saw hlau swb rau ntawm cov menyuam hnyav dhau los ntawm nruab nrab sab nplhaib, thiab lub nplhaib nruab nrab ntawm lub nplhaib meshing nrog lub ntsiab tsav lub hnub qub log tsav lub saw phaj tig, thiaj li ua tiav lub hom phiaj ntawm kev thauj ore. Vim tias qhov chaw ntawm cov saw hlau feem ntau cuam tshuam los ntawm kev cuam tshuam ntawm cov ore thiab kev ua ntawm tus kheej - hnyav, cov saw hlau zoo li elongated thiab poob.
Elongated, ntog saw phaj yuav khawb rau hauv lub mine to nozzle, ua rau cov saw phaj thiab to taub nozzle daig, ua rau cov khoom kaw. Feem ntau muaj ntau cov ore ntawm qhov chaw ua haujlwm ntawm cov saw hlau, feem ntau yog nyob rau hauv thaj tsam ntawm 40 ~ 60t. Yog li ntawd, tom qab kev cuam tshuam nrog qhov tsis ua haujlwm ntawm cov saw hlau thiab cov xau nozzle, peb yuav tsum tau nrog ib feem ntawm cov ore ntawm cov saw hlau (feem ntau txog 20t), uas txwv tsis pub ntau lawm.
Raws li qhov xwm txheej saum toj no, nrhiav ntau yam ntaub ntawv thiab cov ntaub ntawv), tom qab kev tshawb fawb thiab kev sib tham, muab tso rau ob qho kev hloov pauv kev hloov pauv: ib qho yog txav mus rau hauv kuv lub qhov dej ntws tawm, ntxiv ib qho I- nqaj tswj saw phaj nyob rau hauv lub ntsiab tsav lub log poob (lub tswv yim 1); Qhov thib ob, lub mine leakage nozzle tsis txav mus los, ntxiv ob txoj kab ntev ntev ntawm cov saw hlau (200mm ntev), thiab nruab cov chais hnyav rau ntawm txoj kab ntev los pab txhawb cov saw hlau zawv zawg, kom tag nrho cov saw phaj khiav elongated tsis poob (tsim 2). Nyob rau hauv txoj kab nrog lub hauv paus ntsiab lus ntawm kev ua kom lub luag haujlwm ntawm cov cuab yeej siv tau yooj yim thiab kev saib xyuas yooj yim, ob qho kev hloov pauv kev hloov pauv tau pom thiab txheeb xyuas.
3.1 Kev Qhia Txog Kev Ua Haujlwm 1 Txawm hais tias qhov qis qis ntawm lub qhov dej ntws tawm tau txav mus los kom tsis txhob khawb, cov ore tsub zuj zuj mus rau lub qhov tso tawm lub taub dej yog tshwm sim los ntawm kev ntsaws lub qhov dej ntws tawm thaum lub sijhawm pub mis, uas cuam tshuam rau kev ua haujlwm ntawm apron feeder rau kev muag khoom. Nyob rau tib lub sij hawm, vim hais tias cov saw phaj slides ntawm lub beam, qhov kuj yog loj, yuav hnav lub beam, lub sij hawm ntev kev ua hauj lwm ua rau beam deformation, tsis yooj yim rau hloov tag nrho hnyav phaj saw phaj, ua rau kom cov kev ua hauj lwm ua hauj lwm.
Nyob rau hauv daim phiaj 2, ob txoj kab ntev nyob rau hauv txoj kev khiav ntawm cov saw phaj yog ntsia nyob rau hauv lub apron feeder, thiab hnyav chais raug ntsia rau ntawm lub longitudinal rails rau kev txhawb nqa kom tsis txhob muaj kev sib txhuam, yog li daws qhov teeb meem ntawm cov saw phaj ntog thiab scraping down lub mine to, thiab kuj muab kev yooj yim rau kev hloov cov saw phaj thiab tu. Qhov no apron feeder txais cov tswv yim 2 rau kev hloov pauv, uas yog kev tshawb fawb ntau dua, tsim nyog, siv tau thiab ua raws li qhov tseeb ntawm qhov chaw.
Los ntawm kev ntxiv ob txoj kab ntev nyob rau hauv lub apron feeder raws li cov cuab yeej txhawb nqa, uas tsis yog nyob rau hauv thawj tsim, los tswj lub caij nplooj ntoos zeeg ntawm lub apron feeder, nws muaj peev xwm txo tau qhov txhaum ntawm lub apron feeder, pab tswj thiab xyuas kom meej ntau lawm. Tom qab ntau tshaj 6 xyoo ntawm kev siv, tsis muaj kev huam yuaj tshwm sim los ntawm kev ua haujlwm elongated ntawm apron feeder=cov cuab yeej, thiab kev hloov pauv tau pom tseeb, nrog cov txiaj ntsig tseem ceeb ntawm kev sib raug zoo thiab kev lag luam . 5. Los ntawm kev kho lub apron feeder rau kev muag khoom, cov nroj tsuag hnav khaub ncaws yuav tsum ntxiv ob txoj kab ntev ntawm txoj kab hauv qab ntawm cov saw hlau, thiab nruab cov saw hlau hnyav rau ntawm qhov ntev ntawm qhov kev txhawb nqa. saw phaj yuav elongated yam tsis poob thaum ua haujlwm. Txoj kev hloov pauv yog qhov tsim nyog dua li txav mus rau hauv kuv lub qhov dej ntws tawm thiab ntxiv ib qho I-beam nyob rau hauv lub log tsav loj los tswj qhov poob ntawm cov saw hlau. Kev hloov ntawm cov saw phaj thiab kev saib xyuas yog yooj yim dua, thiab kev ua tau zoo yog muaj zog. Tom qab kev hloov pauv kev ua tiav, cov cuab yeej kaw tau tshwm sim los ntawm cov saw hlau elongating, ntog thiab tom qab ntawd scraping down lub mine to nozzle yog daws, thiab cov khoom du yog guaranteed. Kev hloov pauv kev xyaum qhia tau hais tias tej zaum yuav muaj qee qhov tsis sib haum xeeb ntawm kev tsim cov cuab yeej siv thiab cov khoom siv tiag tiag, uas yuav tsum muaj cov neeg ua haujlwm ntawm qhov chaw tsim khoom los ua cov kev soj ntsuam tshwj xeeb raws li cov teeb meem tiag tiag, ua tib zoo xav txog kev saib xyuas thiab hloov cov khoom siv yooj yim, kev khiav hauj lwm yooj yim thiab kev saib xyuas, tsim cov kev hloov pauv kev tshawb fawb thiab tsim nyog, daws cov teeb meem nyuaj txwv kev tsim khoom, thiab xyuas kom ruaj khov thiab nyab xeeb kev ua haujlwm.
