Mining dump tsheb lub cev yog tas li raug cuam tshuam los ntawm ore thiab kev sib txhuam tsis tu ncua ntawm cov xuab zeb thiab pob zeb. Xaiv qhov hnav tsis raug- cov phaj hlau tiv taus tuaj yeem ua rau muaj teeb meem. Qhov zoo tshaj plaws, hauv ob sab phlu yuav hnav los ntawm ob peb lub hlis xwb, ua rau tsis tshua muaj sijhawm poob thiab cuam tshuam cov mining ntau lawm. Qhov phem tshaj plaws, daim hlau yuav tawg vim muaj kev cuam tshuam, tsim kev nyab xeeb kev nyab xeeb thiab nce nqi kho tag nrho. Tam sim no, NM400 thiab NM450 yog cov khoom siv feem ntau siv- cov hlau tsis muaj zog hauv cov mines thiab cov tsheb thauj khoom tsuas yog cov tuam txhab hauv tebchaws thiab thoob ntiaj teb. Ntau tus neeg yuav khoom muag tsis pom kev xaiv raws li tus nqi nkaus xwb, ua rau tsis tsim nyog poob. Kab lus no suav nrog cov xwm txheej ua haujlwm, kev ua haujlwm, thiab tag nrho- cov nqi voj voog los muab cov qauv kev yuav khoom rau koj, ua kom yooj yim rau koj kom nrawm nrawm rau cov phaj zoo rau koj cov kev xav tau.
Ua ntej, cia peb sib piv cov kev yuav khoom tseem ceeb ntawm ob lub steels. NM400 muaj Brinell hardness ntau ntawm 370-430 HB. Nws cov txiaj ntsig tseem ceeb yog qhov ua tau zoo heev, muaj zog tiv thaiv pob zeb cuam tshuam, qis carbon sib npaug, thiab txo qis rau kev txiav, txias khoov, thiab ntawm - qhov chaw vuam. Txawm hais tias tsis muaj cov cuab yeej tshwj xeeb hauv cov mines hauv av, cov neeg ua haujlwm tuaj yeem kho cov kab puas tsuaj ntawm - qhov chaw, muab kev yooj yim ntawm kev tsim kho thiab cov nqi sib tw ntau dua ib tuj. Cov ntawv thov tsim nyog yog tsom rau hauv nqaim- lub cev hauv av mining tsheb thiab luv- tsheb thauj mus los, feem ntau yog siv rau sab vaj huam sib luag, nraub qaum tiv thaiv baffles, thiab hauv ob sab phlu rau cov ntaub ntawv softer (av, shale, ya tshauv). Nws yog qhov tsim nyog rau cov mines me me thiab nruab nrab uas tswj cov peev txheej pib.
NM450 muaj qhov nruab nrab hardness ntawm 430-470 HB, muab ntau dua 30% txhim kho hnav tsis kam piv rau NM400. Rau ntev - thauj mus los ntawm siab- cov ntaub ntawv hardness xws li granite thiab hlau ore, nws txo qis hnav tus nqi, ncaj qha mus txuas ntxiv lub voj voog hloov hauv ob sab phlu. NM450 yog qhov kev xaiv zoo tshaj plaws rau qhib -qhov dav- lub cev hnyav- lub luag haujlwm mining tsheb, mines nrog unloading drops tshaj 5 meters, thiab aggregate tsheb thauj mus los, tshwj xeeb tshaj yog rau high-wear core Cheebtsam xws li hauv pem teb thiab pem hauv ntej baffle.
Raws li kev paub dhau los xyoo dhau los hauv kev xa tawm- qib qib, kev sib xyaw ua ke yog qhov kev daws teeb meem zoo tshaj plaws rau cov mines feem ntau, zam kev siv ib qho khoom siv rau tag nrho lub tsheb: NM450 yog siv rau siab -cov tub ntxhais hauv cheeb tsam xws li hauv pem teb, unloading chaw nres nkoj, thiab pem hauv ntej baffle kom ntev kev pab cuam lub neej; NM400 yog siv rau tsawg dua - hnav thaj chaw xws li sab vaj huam sib luag thiab txheej tiv thaiv sab saud los tswj tag nrho cov nqi yuav khoom, ntsuas qhov hnav tsis kam thiab cov khoom siv peev. Qhov no yog ib lub tswv yim kev yuav khoom uas xav txog ob qho tib si luv-cov nqi sijhawm thiab ntev- lub peev xwm tsim khoom.
Rau ntev -lub sij hawm, loj- ntim qhib- qhov mining nrog siab- hardness ore thiab nquag thauj mus los txhua hnub: Ua ntej NM450 rau hauv pem teb. Txawm hais tias tus nqi pib yuav khoom yog siab dua, nws txo qis cov nqi zais ntawm kev tshem tawm thiab rov sib dhos cov hlua thiab cov sijhawm poob qis, ua rau cov nqi qis dua. Rau kev ua haujlwm hauv av nrog cov ntaub ntawv softer, txwv kev ua haujlwm thiab kev saib xyuas hauv cheeb tsam mining, thiab me me - mus rau - nruab nrab - nplai luv - thauj mus los: Siv NM400 rau tag nrho lub tsheb lossis sab vaj huam sib luag. Nws muaj kev saib xyuas yooj yim, tus nqi qis dua, thiab ua tau raws li cov kev xav tau tsim khoom txhua hnub.
Ntxiv nrog rau cov lus pom zoo, peb kuj tseem muab ib qho - nres kev pab cuam rau kev yuav khoom thiab kev ua haujlwm: raws li tus neeg siv khoom lub tsheb qauv, cov khoom siv mining, thiab qhov siab qhov siab, peb muab tag nrho cov phaj thickness faib cov phiaj xwm; peb txhawb nqa laser txiav, CNC dabtsi yog khoov, thiab beveling prefabrication, tso cai rau kev sib dhos ncaj qha ntawm cov ntawv tiav tiav thaum tuaj txog. Tag nrho cov kev txiav txim xa tawm tuaj nrog daim ntawv pov thawj zoo, ua tiav cov ntaub ntawv tshem tawm kev lis kev cai, thiab tau ntim rau hauv xeb- cov ntaub ntawv pov thawj ntoo rau kev xa dej hiav txwv los tiv thaiv corrosion.
