The second category is secondary aggregates. These aggregates come as a byproduct of other industrial operations or quarrying processes. For example, through the demolition of buildings or other structures, road planings or railway track ballast. Recycled aggregates are secondary aggregates. View some of our recycled aggregates below:
The ballast is cleaned in large oscillating screens with several screening levels which ensures optimum quality. The clean ballast is returned to the track directly behind the excavating chain. The residue from the cleaning is passed into a spoil conveyor and transport system. Ballast cleaning machines with supply of new ballast.
Use of Waste Rock. Railway Ballast: The requirement of railway ballast is that it is not fragile under vibration pressure.Of course, the rock developed by lamination or bedding is not suitable to be used as road slag, while limestone and basalt are more suitable to be used as railway ballast.
ST aggregate screens are ideal for screening crushed rock as well as sand and gravel to produce aggregates for concrete and asphalt, road base, building foundations and railway ballast.
