Ib yam khoom, Ib qho kev daws teeb meem zoo
Thaum nws los txog rau crushing, cov khoom uas koj txheej txheem dictates txhua yam - los ntawm hom hnav qhov chaw koj xav tau rau lawv lub neej kev cia siab. Granite xav tau kev cuam tshuam -resistant manganese steel; limestone tau txais txiaj ntsig los ntawm siab -chrome alloys; hlau ore yuav tsum muaj qhov sib npaug ntawm hardness thiab toughness.
Ntawm Duma Machinery, peb tsis ntseeg hauv ib qho -size- haum- tag nrho. Nrog peb 42,000㎡ nyob rau hauv -lub tsev foundry, metallurgical laboratory, thiab 4,000+ cov qauv uas npog lub ntiaj teb no hom, peb engineers hnav qhov chaw uas phim koj cov khoom tshwj xeeb yam ntxwv. Txawm hais tias koj tab tom crushing nyuaj granite, abrasive quartz, los yog recycling pob zeb, peb pab koj mus ntev hnav lub neej, txo downtime, thiab txo koj cov nqi ib tuj.
Qhov zais cia rau Duma txoj kev vam meej nyob hauv peb txoj kev nkag siab ntawm Austenitic Manganese Steel. Thaum crushing cov ntaub ntawv nyuaj zoo li Granite, qhov cuam tshuam ua rau muaj kev hloov pauv ntawm molecular ntawm peb cov ntaub, ua kom tawv tawv los ntawm HB200 mus rau HB500, thaum lub hauv paus tseem tawv kom nqus tau cov shocks. Yog tsis muaj cov khoom siv zoo-rau-ore match, koj yuav muaj kev pheej hmoo ntawm kev tawg ntxov ntxov los yog hnav sai sai.
Hauv qab no yog cov lus qhia rau kev xaiv txoj cai crusher coj qhov chaw raws li cov khoom koj ua. Txhua qhov kev pom zoo yog txhawb nqa los ntawm peb cov kws tshaj lij metallurgical thiab kev tswj xyuas nruj.
