Kev thov thoob ntiaj teb rau cov khoom siv crusher ua haujlwm siab tau nce siab tas li hauv xyoo 2026, tsav los ntawm kev nthuav dav ntawm cov khoom siv hauv paus, kev siv cov peev txheej hauv av, thiab kev thawb thoob plaws kev lag luam kom txo lub sijhawm ua haujlwm tsis ua haujlwm thiab tag nrho cov nqi tsim khoom. Cov ntaub ntawv tshawb fawb kev lag luam qhia tau hais tias kev lag luam thoob ntiaj teb crusher hnav khoom tau mus txog USD 3.14 billion hauv xyoo 2025, thiab kwv yees tias yuav ncav cuag USD 4.37 billion los ntawm xyoo 2032, tswj hwm tus nqi loj hlob txhua xyoo (CAGR) ntawm 4.8%. Cov phaj puab tsaig, cov khoom siv cone, cov khoom siv cuam tshuam, cov rauj thiab cov ntu concave - cov khoom siv tseem ceeb rau lub puab tsaig, cone thiab cov khoom siv cuam tshuam - suav txog ze li ntawm 20% ntawm tag nrho cov nuj nqis txij nkawm ntawm cov chaw ua pob zeb thiab cov chaw ua cov khoom siv hauv av, ua rau kev tsim kho tshiab cov khoom siv yog qhov tseem ceeb ntawm kev sib tw thoob plaws cov khoom xa tuaj.
Ib txwm muaj, cov hlau manganese siab (Mn13, Mn18Cr2) yog cov khoom siv tseem ceeb rau cov khoom siv crusher hnav, muaj nqis rau nws cov khoom siv tshwj xeeb uas ua rau tawv thaum muaj kev sib tsoo hnyav, uas ua rau qhov chaw tawv thaum tseem khaws cov tawv sab hauv kom tiv taus kev tawg thaum lub sijhawm sib tsoo granite, basalt thiab hlau ore. Txawm li cas los xij, cov khoom manganese ib txwm muaj feem yuav tsum tau hloov txhua 6 txog 8 lub lis piam thaum muaj kev ua haujlwm hnyav, ua rau lub tshuab kaw ntau zaus, ua haujlwm rhuav tshem ntau yam thiab ua haujlwm tsis ruaj khov.
Txhawm rau teb rau qhov teeb meem no, cov tuam txhab tsim khoom siv hnav tau ua kom nrawm dua kev lag luam ntawm cov kev daws teeb meem alloy thiab cov thev naus laus zis sib xyaw ua ke xyoo no. Cov hlau cam khwb cia uas muaj chromium siab tau dhau los ua lwm txoj hauv kev pheej yig rau cov xwm txheej sib tsoo uas tsis muaj kev cuam tshuam, kev sib txhuam siab xws li limestone thiab kev siv cov khib nyiab hauv kev tsim kho dua tshiab, xa 25% lub neej ua haujlwm ntev dua li cov hlau manganese txheem ntawm tus nqi tsim khoom sib piv. Qhov kev hloov pauv hloov pauv tshaj plaws los ntawm titanium carbide (TiC) ntxig cov khoom hnav, qhov twg cov pas nrig TiC nyuaj heev tau muab tso rau ntawm qhov chaw ua haujlwm ntawm cov liners thiab cov phaj puab tsaig. Kev sim hauv thaj chaw ntawm lub chaw khawb hlau Australian tau lees paub tias TiC composite cone liners tau ntev lub neej ua haujlwm los ntawm tsuas yog 7 hnub rau OEM tus qauv liners mus rau ntau dua 20 hnub, tsa lub neej ntawm cov khoom los ntawm ntau dua 200% thiab txo qhov zaus hloov liner txhua xyoo.
Kev tsim qauv tshwj xeeb kuj tau tshwm sim los ua tus tsav tsheb loj hlob tseem ceeb. Hloov chaw ntawm cov txheej txheem thoob ntiaj teb, cov chaw tsim khoom tam sim no kho cov qauv kab ntawm cov kab raws li qhov nyuaj ntawm cov hlau, qhov loj me ntawm cov khoom noj thiab qhov sib xyaw ua tiav. Cov qauv geometric zoo tshaj plaws tsis tsuas yog ua rau qeeb qeeb tsis sib xws xwb tab sis kuj ua rau muaj kev sib tsoo ntau ntxiv los ntawm 8% -15% thaum txo qis kev siv hluav taws xob ib tuj ntawm cov khoom sib tsoo. Lub caij no, kev lag luam tab tom hloov pauv los ntawm kev muag khoom ib qho mus rau tus qauv "khoom + kev pabcuam" tag nrho, suav nrog kev saib xyuas qhov xwm txheej hnav, kev teem sijhawm txij nkawm thiab kev taw qhia kev teeb tsa hauv tsev. Cov ntaub ntawv los ntawm Tuam Tshoj Aggregates Association qhia tias cov kev daws teeb meem hnav tshwj xeeb zoo tshaj plaws tuaj yeem txo qhov kev poob sijhawm tsis tau npaj tseg rau cov nroj tsuag sib tsoo los ntawm 12% txog 18% txhua xyoo.
Nyob rau thaj chaw, Asia-Pacific tseem yog lub chaw siv thiab tsim khoom loj tshaj plaws rau cov khoom siv crusher. Kev nqis peev ruaj khov hauv kev tsim kho vaj tse thoob plaws Southeast Asia, Central Asia thiab Africa ua rau muaj kev thov hloov khoom siv tom qab, thaum cov chaw tsim khoom hauv Suav teb tau loj hlob mus rau hauv lub hauv paus xa khoom loj tshaj plaws hauv ntiaj teb rau cov khoom siv pheej yig, tau ntawv pov thawj, sib tw nrog cov tuam txhab loj thoob ntiaj teb Metso, Weir Group thiab Magotteaux hauv ob qho tib si nruab nrab thiab qib siab. Cov kws tshuaj ntsuam xyuas kev lag luam sau tseg tias kev sib tw yav tom ntej yuav tsis tsuas yog vam khom tus nqi khoom siv raw xwb, tab sis ntawm cov peev xwm sib xyaw ua ke uas suav nrog kev tshawb fawb thiab kev tsim khoom siv hlau, kev tsim khoom siv, kev tsim kho daim ntawv thov thiab kev xa khoom sai thoob ntiaj teb.
Kev ruaj khov kuj tau koom ua ke rau hauv cov khoom rov ua dua. Feem ntau cov khoom siv crusher zoo tshaj plaws tuaj yeem rov ua dua tshiab tom qab lub neej ua haujlwm, thaum cov qauv tsim ntev zoo tshaj plaws txo cov hlau nyoos thiab cov pa roj carbon los ntawm kev tsim khoom thiab kev thauj mus los ntau zaus. Raws li cov neeg ua haujlwm hauv chaw ua pob zeb ntau ntxiv muab qhov tseem ceeb rau tag nrho cov nqi ntawm kev muaj tswv dua li tus nqi yuav khoom ua ntej, cov khoom siv crusher uas ruaj khov, tshwj xeeb rau daim ntawv thov tau teeb tsa kom tswj tau kev nthuav dav ntawm kev lag luam thoob plaws rau rau xyoo tom ntej, rov txhais cov qauv kev ua haujlwm zoo rau kev lag luam crushing thoob ntiaj teb.
