Hauv qhov xav tau ib puag ncig ntawm cov chaw txua txiag zeb lossis mine, lub crusher rauj yog qhov tseem ceeb tshaj plaws. Txawm li cas los xij, ntau tus neeg ua haujlwm ntsib tib yam teeb meem ntxhov siab:Hnav Ua Ntej.Thaum lub rauj ua tsis tiav lub lis piam ua ntej nws lub neej kev pab cuam, nws tsis yog nce tus nqi seem - nws tua koj lub sijhawm ua haujlwm.
NtawmDuma Machinery, peb tau txheeb xyuas ntau txhiab tus qauv coj hauv peb42,000 m² os. Feem ntau qhov ua tsis tiav ntxov tsis yog "kev hmoov phem"- kev ua haujlwm tshwj xeeb tsis sib haum ua rau lawv.
Ntawm no yog 5 feem ntau ua rau kom ceev rauj hnav thiab cov kev daws teeb meem engineering los kho lawv.
Duma Machinery 42,000 m² foundry
1. Khoom siv tsis sib xws (Alloy vs. Rock Hardness)
Cov tsos mob:Lub ntsej muag rauj flattens yuav luag tam sim ntawd, qhia qhov "ntxuav-tawm" zoo li.
Kev Ntsuam Xyuas:Qhov no yog qhov yuam kev xaiv classic. Xaiv ib lub rauj raws li cov ntsiab lus ntawm manganese yam tsis xav txog qhovCov ntsiab lus ntawm Silica (SiO2).ntawm koj pob zeb yog yuam kev. Yog tias koj tab tom crushing cov ntaub ntawv abrasive xws li granite los yog basalt nrog cov qauv manganese steel, qhov saum npoo tsis tuaj yeem ua haujlwm tau - harden ceev txaus los tiv thaiv kev puas tsuaj.
Kev daws: * Hloov kho rau Mn22Cr2:Rau siab -silica pob zeb, siv Duma'sMn22Cr2 (Ultra-High Manganese)hlau alloy.
Ceramic Composites:Rau cov xwm txheej hnyav, xav txogTiC (Titanium Carbide) kem inserts. Cov "cov tawv nqaij" no tiv thaiv kev puas tsuaj thaum lub hauv paus manganese muab qhov tsim nyog cuam tshuam toughness.

2. Tshaj Rotor ceev (RPM)
Cov tsos mob:Lub rauj tsim ib puag ncig, "pob{0}}zoo li" hnav cov qauv ntawm lub taub es tsis hnav sib npaug ntawm lub ntsej muag.
Kev Ntsuam Xyuas:Ntau tus neeg ua haujlwm nce RPM xav tias nws txhawb kev tsim khoom. Txawm li cas los xij, yog tias qhov nrawm dhau, cov khoom siv tsis tuaj yeem "nkag mus" rau rauj qhov chaw tawm tsam. Xwb, lub pob zeb tsuas yog thaws tawm ntawm ntug, ua rau khauskev sib txhuam hnaves tsis cuam tshuam crushing.
Kev daws: * Optimize RPM:Kho koj lub rotor ceev kom cov khoom nkag mus yam tsawg kawg nkaus1/3 ntawm txoj kevmus rau hauv lub rauj txoj kev.
Precision Balancing:Duma hammers yogcomputer- sib npaugnyob rau hauv cov teeb tsa kom tshem tawm kev co ntawm kev kub ceev, txo qis eccentric hnav ntawm lub rotor.,
3. "Tshaj -Crushing" Vim Tight Grate Bar Spacing
Cov tsos mob:Thaum tshav kub kub nyob rau hauv lub crushing chamber thiab txawv txawv hnav nyob ze rau rauj shank (lub hauv paus).
Kev Ntsuam Xyuas:Yog tias koj cov grate tso tawm los yog cov ntxaij vab tshaus tau teeb tsa nruj heev, cov khoom tiav tsis tuaj yeem khiav tawm. Nws nyob hauv lub chamber, tsim kom muaj "cov ntaub ntawv txaj." Koj cov hammers xaus rau nplawm cov khoom no zoo li rab riam, ua rau loj heevlwm yam hnav.
Kev daws: * Grate Adjustment:Qhib lub grate qhov sib nrug mus rau qhov siab tshaj plaws uas tso cai rau koj cov khoom tiav.
Chamber Optimization:Siv Duma's digital kab noj hniav simulation los xyuas kom meej tias koj liners thiab hammers ua hauj lwm ua ke kom khiav tawm cov khoom zoo.
4. Ua tsis tiav "Ua hauj lwm-Hardening"
Cov tsos mob:Lub rauj zoo li "ci" tab sis cov hlau yog tev tawm hauv nyias txheej (spalling).
Kev Ntsuam Xyuas:Manganese steel's "magic" yog nws lub peev xwm los ua kom muaj zog hauv kev cuam tshuam. Txawm li cas los xij, yog tias koj cov khoom noj me me dhau los yog mos dhau lawm, qhov cuam tshuam lub zog tsis siab txaus los hloov qhov chaw los ntawmHB 200rau qhov xav tauHB500. Koj yog qhov tseem ceeb "mos-rubbing" cov hlau tam sim ntawd.
Kev daws: * Feed Calibration:Xyuas kom koj qhov pub me me muab lub zog kinetic txaus los ua rau cov lus teb nyuaj.
Austenitic Integrity:Duma siv qhov tshwj xeebDej Toughening txheej txheemkom paub meej a100% ntshiab austenite qauv. Qhov no tau lees tias thaum muaj kev cuam tshuam tshwm sim, cov lus teb hardening yog instantaneous.,

5. Cov dej noo thiab av nplaum nplaum
Cov tsos mob:Pitting rau ntawm qhov chaw rauj thiab qhov tseem ceeb ntawm kev hnav khaub ncaws thaum lub caij los nag.
Kev Ntsuam Xyuas:Thaum cov dej noo ntau tshaj 10%, cov khoom zoo yuav nplaum thiab clings rau cov phab ntsa chamber. Qhov no tsim ib qho "tswj" qhov twg rauj sib ntaus los ntawm av nkos, ua raucorrosion- hnavthiab nce luag.
Kev daws: * Ua ntej-Kev tshuaj ntsuam:Siv lub grizzly feeder tshem tawm cov nplua thiab av nplaum ua ntej lawv nkag mus rau hauv lub crusher.
Kev kho chromium:Ntawm Duma, peb tuaj yeem nce me ntsisChromium (Cr)feem pua ntawm koj cov alloy los txhim kho oxidation thiab corrosion kuj rau qhov chaw ntub dej.
