Geotechnical Properties of Soil-Ball Milled Soil Mixtures | SpringerLinkAbstract. Laboratory experiments were conducted to study the fundamental geotechnical properties of mixtures of natural soils and its product after ball milling operation. The product after ball milling process is termed nano-soil herein. SEM analysis showed that much more nano size particles were obtained after the milling.ball milling, soils,Remediation of heavy metals contaminated soils by ball milling .In the present work, the use of ball milling reactors for the remediation of lead contaminated soils was investigated. Lead immobilization was achieved without the use of additional reactants but only through the exploitation of weak transformations induced on the treated soil by mechanical loads taking place during.
