Lub puab tsaig crusher hniav phaj-feem ntau hu ua "lub puab tsaig phaj" los yog "lub puab tsaig liner"- yog ib qho tseem ceeb hnav- cov khoom tiv thaiv ntawm lub puab tsaig crusher. Nws muaj ob hom: lub puab tsaig ruaj khov thiab lub puab tsaig txav tau; cov khoom yog crushed los ntawm kev sib nrig sib compression exerted los ntawm ob daim hlau no.
Lub puab tsaig phaj feem ntau yog tsim los ntawm cov khoom xws li siab -manganese steel. Tej zaum lawv yuav muaj ntau yam qauv tsim-xws li segmented lossis nkhaus profiles- thiab tau ruaj khov rau lub tshuab thav duab thiab lub puab tsaig txav tau siv bolts lossis wedges. Thaum hnav, lawv lub neej kev pabcuam feem ntau tuaj yeem txuas ntxiv los ntawm flipping, swapping, lossis hloov cov phiaj.
Lub puab tsaig phaj yog cov feem ntau siv cov khoom seem hauv lub puab tsaig crushers; Lwm cov npe muaj xws li "cov ntawv hniav" thiab "lub puab tsaig liner."
Lub puab tsaig phaj nyob rau hauv lub puab tsaig crusher yog categorized rau hauv taag thiab txav tau hom, ua thawj coj-cov khoom tiv thaiv ntawm lub tshuab.
Lub puab tsaig phaj yog tsim los siv rau hauv lub puab tsaig crushers thiab cov cuab yeej zoo sib xws.
Nyob ntawm tus qauv tshwj xeeb ntawm lub puab tsaig crusher, lub puab tsaig daim hlau muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab specifications.
Thaum lub sij hawm ua haujlwm ntawm lub puab tsaig crusher, lub puab tsaig txav tau- haum nrog lub puab tsaig txav tau lub puab tsaig- ua haujlwm rov ua dua; Qhov kev txiav txim no tsim lub kaum sab xis ntawm lub puab tsaig ruaj khov, yog li crushing cov khoom siv pob zeb. Yog li ntawd, lub puab tsaig phaj yog ib qho ntawm cov khoom nyob rau hauv lub puab tsaig crusher feem ntau raug rau kev puas tsuaj (tseem hu ua "hnav").
Cov khoom muaj pes tsawg leeg ntawm lub puab tsaig crusher tus hniav phaj ncaj qha cuam tshuam nws cov hnav tsis kam, kev pabcuam lub neej, thiab kev ua haujlwm zoo. Cov khoom siv tsoos feem ntau muaj cov siab -manganese steels- xws li ZGMn13, Mn13Cr2, thiab Mn18Cr2- uas muaj kev tiv thaiv zoo heev rau kev cuam tshuam kev thauj khoom thiab muaj peev xwm ua haujlwm zoo dua.
Txawm li cas los xij, nyob rau hauv qee qhov kev ua haujlwm, kev ua haujlwm tsis txaus- tuaj yeem ua kom tawv tawv tuaj yeem tshwm sim, uas ua rau kom nrawm nrawm ntawm daim hlau. Txhawm rau txhim kho kev ua tau zoo, ntau cov ntaub ntawv txhim kho tau tsim: Hloov siab -manganese steel- ua tiav kev hloov kho lossis kev sib zog ua kom muaj zog ntxiv los ntawm kev sib ntxiv ntawm cov ntsiab lus xws li Cr, Mo, W, Ti, V, thiab Nb los txhawb kev pib hardness thiab yield zog; Nruab nrab-manganese steel- characterized los ntawm qis austenite stability, uas yooj yim induces martensitic theem transformation raws li qhov cuam tshuam, yog li txhim kho hnav tsis kam los ntawm ntau tshaj 20% piv rau cov tsoos siab -manganese steel; Nruab nrab-carbon low- alloy cam khwb cia hlau- sib txuas siab hardness nrog txaus toughness los tiv thaiv txiav abrasion thiab qaug zog spalling tshwm sim los ntawm repetitive cov ntaub ntawv compression, muab ib tug kev pab cuam lub neej ntau tshaj peb zaug ntev tshaj li ntawm siab -manganese steel; thiab bimetallic composite cov ntaub ntawv-xws li composites ntawm siab -chromium cam khwb cia hlau thiab siab -manganese los yog qis- alloy steel- uas leverage lub superior hnav tsis kam ntawm txheej txheej thiab lub siab toughness ntawm lub hauv paus txheej kom ua tau ib tug txheeb ze hnav kuj 00%.
Kev xaiv cov khoom yuav tsum muaj kev txiav txim siab zoo ntawm cov khoom xws li kev cuam tshuam kev thauj khoom, cov khoom siv hardness, thiab hnav mechanisms. Rau cov loj- nplai crushers, uas yuav raug rau hnyav loads, hloov kho los yog dispersion- ntxiv dag zog rau siab -manganese hlau yog qhov kev xaiv; rau nruab nrab- thiab me- nplai crushers, qhov twg cuam tshuam cov loads kuj qis dua, xaiv nruab nrab -carbon low- alloy steel los yog siab -chromium cam khwb cia hlau / qis- alloy steel composites muaj ntau dua kev kawm thiab kev lag luam. Thaum ua cov ntaub ntawv nyuaj, qhov tseem ceeb yuav tsum tau muab rau cov ntaub ntawv uas muaj hardness siab. Yog hais tias txiav abrasion yog qhov tseem ceeb hnav mechanism, xaiv cov khoom yuav tsum tau ua ntej hardness; conversely, yog hais tias cov yas deformation los yog qaug zog hnav yog lub hauv paus mechanism, lub hom phiaj yuav tsum tau muab tso rau ntawm cov khoom plasticity thiab toughness.
