Lub pob zeb yog ib hom kev sib tsoo siv los zom lossis sib xyaw cov ntaub ntawv siv rau hauv cov txheej txheem hnav khaub ncaws, xim, pyrotechnics, ceramics, thiab xaiv laser sintering. Nws ua haujlwm ntawm lub hauv paus ntsiab lus ntawm kev cuam tshuam thiab attrition: txo qhov luaj li cas yog ua los ntawm kev cuam tshuam thaum cov khoom poob los ntawm ze rau saum lub plhaub.
Lub pob zeb muaj lub hollow cylindrical plhaub rotating txog nws axis. Lub axis ntawm lub plhaub yuav yog kab rov tav lossis ntawm lub kaum me me rau kab rov tav. Nws yog ib nrab ntim nrog pob. Cov xov xwm sib tsoo yog cov pob, uas tuaj yeem ua los ntawm cov hlau (chrome steel), stainless hlau, ceramic, lossis roj hmab. Sab hauv ntawm lub plhaub cylindrical feem ntau yog kab nrog cov khoom siv tsis zoo xws li manganese steel lossis roj hmab hauv ob sab phlu. Tsawg hnav tshwm sim nyob rau hauv cov roj hmab lined mills. Qhov ntev ntawm lub zeb yog kwv yees li sib npaug rau nws txoj kab uas hla.
Lub tswv yim dav dav tom qab lub pob zeb yog ib qho qub, tab sis nws tsis yog kom txog rau thaum muaj kev hloov pauv thiab kev tsim lub zog hluav taws xob uas lub tshuab pob zeb zoo tuaj yeem tsim tau. Nws tau tshaj tawm tias tau siv rau kev sib tsoo flint rau cov tais diav hauv xyoo 1870
Ua haujlwm
Nyob rau hauv cov ntaub ntawv ntawm lub pob zeb ua haujlwm tsis tu ncua, cov khoom siv hauv av yog pub los ntawm sab laug los ntawm 60 degree lub khob hliav qab thiab cov khoom raug tso tawm los ntawm 30 degree cone mus rau sab xis. Raws li lub plhaub rotates, cov pob yog lifted rau ntawm lub nce toj ntawm lub plhaub thiab ces lawv cascade down (los yog poob rau hauv lub pub), los ntawm ze rau sab saum toj ntawm lub plhaub. Nyob rau hauv tas li ntawd, cov khoom hais nyob rau hauv nruab nrab ntawm lub pob thiab hauv av yog txo nyob rau hauv loj los ntawm kev cuam tshuam.
Daim ntawv thov
Pob zeb mills yog siv rau kev sib tsoo cov ntaub ntawv xws li mining ores, thee, pigments, thiab feldspar rau pottery. Kev sib tsoo tuaj yeem nqa tawm ntub lossis qhuav, tab sis yav dhau los ua haujlwm ntawm qhov nrawm. Pob zeb mills feem ntau siv rau hauv kev tshawb fawb los txo qhov me me, tshem tawm cov agglomeration, hloov cov duab ntawm cov khoom, muab cov khoom siv sib xyaw, sib tov, tsim cov hmoov thiab cov khoom siv hloov khoom siv[2] Lub pob zeb qhib pob zeb tau tsim los uas tuaj yeem tsim nrog lub tshuab luam ntawv 3D rau ob peb puas duas las.[3] Nws muaj peev xwm ua tau ob qho tib si ntawm kab sib chaws rau kev ua haujlwm hauv chav kuaj thiab tawm daim phiaj nrog hnub ci photovoltaics thiab lub roj teeb rau kev ua haujlwm. Kev sib xyaw ntawm cov khoom tawg yog ib qho piv txwv ntawm daim ntawv thov rau pob roj hmab.[4] Rau cov tshuab uas muaj ntau yam khoom, pob milling tau pom tias ua tau zoo hauv kev ua kom muaj zog-state chemical reactivity.[5] Tsis tas li ntawd, pob milling tau pom tias muaj txiaj ntsig zoo rau kev tsim cov khoom siv amorphous.[5] Nws kuj tseem yuav pab tau kom cais cov pa roj xws li hydrogen thiab khaws cia rau hauv cov hmoov hmoov.[6][7]
