Teknolojiyada Nadiifinta Ballast

Marka la dhisayo waddooyinka iyo tareenada, aggareeyaha qaab-dhismeedka leh, badanaa qaab ahaan super-granite oo caan ku ah adkaysigiisa aan caadiga ahayn, ayaa loo isticmaalaa sidii ballast. Marka la burburinayo agabkan, hab istiraatiijiyadeed ayaa la qaataa, iyadoo mashiinka jaw crusher uu yahay marxaladda koowaad, oo awood leh si loo burburiyo qaybo waaweyn. Kadib, mashiinka cone crusher ayaa qaata marxaladda labaad ama saddexaad, isagoo sii hagaajinaya agabka la burburiyey si loo hubiyo in ay leedahay isaga midnimo iyo waxqabadka ugu wanaagsan marka la dhigo lakabka ballast.
