NM400 tuaj yeem siv lub tshuab classic qhov
Qhov ntau aperture rau NM400 sieve daim hlau yog 3-50 mm. Ultra- me me apertures (<3 mm) or very thick plates (>40 mm) yuav tsum muaj cov txheej txheem tshwj xeeb (xws li laser / EDM) thiab kev txheeb xyuas ntawm qhov qhib qhov sib piv thiab tawg tsis kam.
Yam tsawg kawg nkaus aperture:Feem ntau tsis tsawg tshaj li 3 hli (2-3 hli yog ua tau rau nyias daim hlau Tsawg dua los yog sib npaug rau 10 hli, tab sis nws yuav deformation los yog tawg; Ntau tshaj los yog sib npaug rau 6-8 hli yog pom zoo rau cov phaj tuab ntau dua los yog sib npaug li 20 hli).
Maximum aperture:Txwv los ntawm tag nrho cov qauv ntawm lub sieve phaj, feem ntau yog < phaj dav / 2. Hauv engineering, ib qho apertures tsis tshua muaj siab tshaj 50 hli (tsis li ntawd, lub zog yuav raug cuam tshuam, yuav tsum tau siv cov perforated + reinforced los yog kab sib chaws).
Qhov zoo ntawm kev siv NM400 hnav-resistant perforated screen
Siab Load Capacity:
Lub npov ruaj khov thiab ruaj khov tuaj yeem tiv taus cov ntaub ntawv tonnage loj, ua tau raws li qhov xav tau ntawm kev tshuaj xyuas tas li nyob rau lub sijhawm ntev.
Abrasion thiab Impact Resistant:
Siv NM400 abrasion-cov ntaub ntawv pov thawj tiv taus, nws khav theeb zoo heev puas thiab cuam tshuam, txo qhov zaus ntawm qhov hloov pauv thiab txo tus nqi kho.
Stable Screening Performance:
Lub aperture tsis tu ncua thiab meej aperture spacing xyuas kom meej cov khoom zoo sib xws, tswj kev ua haujlwm siab zoo.
Cov khoom siv qis qis:
Optimized aperture layout tso cai rau cov ntaub ntawv du, txo qhov tshwm sim ntawm kev tshuaj ntsuam clogging.
Lub neej ua haujlwm ntev:
Piv nrog rau cov ntxaij vab tshaus, nws muaj lub neej ua haujlwm ntev dua nyob rau hauv cov xwm txheej ntawm kev puas tsuaj siab.
Daim ntawv thov ntawm NM400 perforated screen
- Mining: Ore thiab pob zeb grading thiab tshuaj ntsuam, coarse tshuaj ntsuam ntawm cov pob zeb nyoos, thiab aggregate sorting.
