Dhuumaha birta dhalaalaysa ee dhammaystiran waa shay bir ah oo sax ah oo sax ah ka dib marka la dhammeeyo sawirka ama duubista qabow. Sababtoo ah derbiyada gudaha iyo dibadda ee tuubooyinka dhalaalaya ee saxda ah ma laha lakabka oksaydhka, ma laha dheecaan cadaadis sare, saxsanaan sare, dhammayn sare, ma laha qallafsanaan inta lagu jiro qaloocinta qabow, foorarsiga, fidinta iyo dildilaaca, iwm. Halabuurka kiimikada ee tuubada dhalaalaya ee saxda ah waxaa ka mid ah kaarboon C, Silicon Si, manganese Mn, sulfur S, fosfooraska P, iyo chromium Cr.
Astaamaha ugu muhiimsan ee dhamaystirka tuubada dhalaalaya:
Darbiyada gudaha iyo dibadda ee tuubada birta waxay leeyihiin saxsanaan sare iyo dhammaystir sare. Daaweynta kulaylka ka dib, tuubada birta ah ma laha lakabka oksaydh, iyo gidaarka gudaha ayaa leh nadaafad sare. Dhuumaha birta ahi waxa ay wataan cadaadis sare, qaloocida qabowgu ma qalloocdo, oo ololka iyo fidsantu ma dillaacdo. Dhammaadka soo giringiriyey tuubooyinka birta ah oo ay bixiso Tianjin Century Zoomlion waxaa loo isticmaali karaa qallafsanaanta kala duwan iyo farsamaynta farsamada. Midabka birta: caddaan iftiin leh, leh dhalaal macdan sare leh.

Codsigadhammayn-tubooyinka dhalaalaya duuban
Gawaarida, qalabka mishiinada iyo mishiinada kale ee leh shuruudaha sare ee saxnaanta iyo jilicsanaanta tuubooyinka birta. Hadda isticmaalayaasha dhamaystirka tuubooyinka birta ah ee duuban ma aha oo kaliya kuwa leh shuruudo sare oo sax ah oo dhammaystiran. Sababtoo ah saxda ah ee dhamaystirka duuban tuubooyinka dhalaalaya waa sarreeyaa, dulqaadkana waxaa lagu hayn karaa 2-8 fiilooyinka, isticmaalayaasha farsamaynta farsamada badan ayaa si tartiib tartiib ah u beddelaya tuubooyinka birta ah ee birta ah ama birta wareegsan si ay u dhammeeyaan tuubooyinka dhalaalaya ee duuban si loo badbaadiyo shaqada, alaabta iyo waqti lumis.
