Surface Feeder yog tsim los ua kom tau raws li cov neeg siv khoom xav tau rau cov khoom siv txawb tau txais thiab tiv thaiv cov dej tawm. Cov khoom siv tuaj yeem ncav cuag lub peev xwm mus txog 1500t / h, max siv dav 2400mm, max siv ntev 50m. Raws li ntau yam ntaub ntawv, max upwards inclination degree yog 23 °.
Nyob rau hauv ib txwm unloading hom, lub dumper yog unloaded mus rau hauv lub feeding ntaus ntawv los ntawm lub underground funnel, ces pauv mus rau lub underground siv thiab thauj mus rau qhov chaw ua hauj lwm. Piv nrog rau cov txheej txheem unloading ib txwm, nws muaj cov yam ntxwv ntawm tsis muaj qhov, tsis muaj underground funnel, tsis muaj kev tsim kho tus nqi siab, qhov chaw hloov tau yooj yim, tag nrho cov tshuab thiab lwm yam.
Los ntawm qhov ua tau zoo ntawm qhov pom, cov cuab yeej tuaj yeem muab faib ua ntu pub rau tib lub sijhawm thiab sab saud (raws li qhov tseeb qhov xwm txheej sab saum toj pub noj kuj tuaj yeem teem caij ua ke).
Cov khoom siv yog tsim los ntawm cov cuab yeej tsav tsheb, cov cuab yeej spindle, tensioning ncej ntaus ntawv, saw phaj ntaus ntawv (xws li saw phaj thiab daim kab xev), saw, ncej, baffle phaj (lub tsev kaw), cov ntaub ntawv pov thawj, thiab lwm yam.
Independent feeders feem ntau yog nruab nrog lub cev muaj zog tsav ncaj qha los koom tes nrog kev sib txuas lossis orthogonal ncej reducers ntsia rau ntawm lub taub hau txuas ntxiv. Hauv kev siv tshwj xeeb, tandem reducers lossis hydraulic drives tuaj yeem siv.
Cov khoom tilting los ntawm lub tsheb thauj khoom mus rau phaj feeder tshwj xeeb kev ua haujlwm tau muab faib ua peb kauj ruam.
1. Ua ntej, cov khoom yog inclined los ntawm lub tsheb thauj khoom mus rau lub phaj feeder khiav rau pem hauv ntej mus rau txoj siv conveyor Nrog kev khiav hauj lwm ntawm txoj siv conveyor, cov ntaub ntawv kiag li qaij los ntawm lub tipper.
2. Tom qab cov ntaub ntawv yog tilted tag, lub pob tseg tsheb tawm, cov ntaub ntawv raug xa mus rau downstream conveying system, thiab lub inlet yog khoob.
3. Tom qab thawj lub tsheb thauj khoom pov tseg tau tawm mus, lwm qhov yog nyob rau hauv qhov chaw. Thaum lub sij hawm no, lub phaj feeder tau thauj cov ntaub ntawv mus rau hauv qab, thiab lub inlet tuaj yeem txais cov ntaub ntawv tshiab.
4. Xws li kev ua haujlwm, voj voog thiab rov ua dua.
