Hauv kev lag luam cement, rauj zeb mills yog qhov tseem ceeb rau kev sib tsoo limestone, thiab qhov zoo ntawm lubHnav-resistant hammerscuam tshuam ncaj qha tsoo cov efficiency thiab khoom siv li ploj. Ib qho ntawm cov ntsiab lus tseem ceeb cuam tshuam rau rauj lub neej yog cov ntsiab lus silicon hauv limestone. Qhov siab dua cov ntsiab lus silicon, cov luv luv lub neej ntawm cov ris-tiv taus rauj. Nws feem ntau pom zoo tias cov ntsiab lus silicon hauv limestone tau khaws cia qis dua 2%. Ntxiv nrog rau cov ntsiab lus silicon, lub zog compressive zog ntawm lub limestone kuj cuam tshuam nrog rab rauj hnav tsis kam. Qhov siab dua lub zog compressive, tus neeg txom nyem tus brittleness, coj mus rau ntau dua kev coj ntawm lub rauj.
Yav dhau los, ntau cov tuam txhab txhim kho cov tshuab raj ua kom muaj cov hlau siab, xws li MN13cr2, uas, tom qab kev kho cua sov, tuaj yeem ncav cuag txoj kev nyuaj ntawm HRC50. Txawm li cas los xij, cov noHnav-resistant hammersFeem ntau muaj cov nyiaj luv luv luv thaum ua nrog limeson uas muaj cov ntsiab lus silicon siab, thiab lawv tuaj yeem tsis tuaj yeem ua cov peev txheej ntau dua 100, {}}} tons ntawm cov khoom. Raws li qhov tshwm sim, ntau lub tuam txhab tau tig mus rau ultra-high manganese steel rauj phaj los yog composite alloy hammers kom txhim kho kev coj tsis kam.
Ntawm cov no, ultra-siab manganese steel rauj phaj (xws li MN18CR2) txhim khu kevHnav-Proseist RaujKev ruaj khov los ntawm kev nce cov ntsiab lus manganese, uas txhim kho cov cua hardnessed. Txawm li cas los xij, kev sib faib ntawm manganese thiab lwm yam alloy cov ntsiab yuav tsum tau ua kom pom tseeb, raws li ntau lub hammer lub zog thiab cuam tshuam tsis kam.
Hnav-resistant composite alloy hammers yog qhov kev xaiv zoo. Los ntawm nce cov alllo cov ntsiab lus hauv kev ua haujlwm ntawm lub rauj (feem ntau chromium) thiab cov rauj zoo zoo txhim kho kev coj tsis kam thiab kav lub neej. Hnav-resistant composite alloy hammers tsis tsuas yog muaj kev nyuaj heev tab sis kuj tswj kev ua kom zoo nyob rau hauv cov kev siv siab ua haujlwm.
Tsis tas li ntawd, qhov zoo tshaj ntawm rauj zeb spare xeem yog cuam tshuam los ntawm ntau yam muaj pes tsawg leeg, cov txheej txheem kho cua sov, thiab qhov tob ntawm kev nyuaj. Cov noob nplej loj, cov ntsiab lus noo ntawm cov ntsiab lus limestone, thiab seb cov crusher qhov kev tso tawm tau qhib tau kuj tseem cuam tshuam txog kev ua haujlwm ntawmHnav-resistant hammers.
Xaiv txoj cai hnav rauj rauj yog qhov tseem ceeb heev rau kev ncua lub neej ntawm cov khoom siv crushing. Duma tshuab muaj kev paub ntau hauv daim teb no thiab tuaj yeem kho cov khoom kom haum rau koj cov kev xav tau. Yog koj muaj lus nug txogHnav-resistant hammers, thov hu rau peb. Peb yuav muab cov kev daws teeb meem rau koj.
