Grate yog hnav ib feem ntawm crusher thiab ib qho tseem ceeb ntawm crusher.Cov khoom siv feem ntau siv hauv crusher ntau lawm yog grate.Cov khoom siv feem ntau siv rau hauv crusher ntau lawm yog sieve tuav.Kev noj cov sieve tuav yog qhov txuas tseem ceeb hauv kuv qhov kev tsim khoom, yog li kev pabcuam lub neej ntawm grate plays lub luag haujlwm tseem ceeb hauv kev tsim tus nqi nyiaj txiag.
Hauv kev tsim cov grate, cov txheej txheem ib txwm yog ib qho yooj yim los ua kom lub ntsej muag deformation ntawm cov khoom, uas tsis tsuas yog nyuaj rau kho, tab sis kuj nce nqi zog.Peb cov thev naus laus zis tshiab muaj peb tus kheej cov kev paub dhau los hauv kev tsim khoom thiab ua cov tshuaj ntsuam strips, uas tuaj yeem daws txhua yam xwm txheej.Hardness, tensile zog, thiab lwm yam. tuaj yeem ua tau raws li cov neeg siv khoom xav tau.Cov zis txhua xyoo tuaj yeem ncav cuag 1600T, kev tswj xyuas zoo thiab kev ua haujlwm siab yog qhov koj xaiv tshiab.
High manganese steel screen bar thiab alloy steel screen bar yog ob hom hauv crushers, uas muaj zoo toughness thiab zoo deformation thiab hardening peev xwm.Cov ntaub ntawv muaj xws li Mn13, Mn13Cr2, Mn18Cr2 (ie ultra-high manganese) lossis cov khoom tshwj xeeb raws li kev ua haujlwm.
Cov ntaub ntawv tseem ceeb (tuaj yeem ua raws li cov neeg siv khoom xav tau.)
