The Process Of Screening Recycle Railway Ballast

Apr 05, 2021

Over time, mainly due to abrasion and wear, ballast loses its mechanical properties and cannot be reused within the rail industry, being sold on to other users to be recycled as an engineering ll material. In the last decade, several cases of railway ballast contamination by organics and inorganic species have been reported [2]
