What is Ballast, Materials for Ballast and Screening

Screening of ballast. The ballast should be renewed from time to time, because due to continuous hammering the ballast converted into the powder form. This powder along with dust, sand ashes from locomotive form an impervious layer and prevent the ease flow of water through ballast. The ballast are constantly press in the formation.

Ballast: what is it and why do we clean and replace

Ballast is the name for the ‘stones’ beneath the track. This aggregate forms the trackbed and supports the track. It also helps with drainage, so rain water can drain away rather than pooling, and with preventing vegetation growth, which could destabilise the track and be a hazard for anyone working on the railway.

Ballast cleaner - Wikipedia

A cutter bar runs beneath sleeper level excavating all of the ballast under the sleepers to a specified, variable depth. A conveyor then moves the ballast into the cleaner, where it gets forced through a mesh by a shaking chamber. Pieces of ballast which are smaller than the mesh size fall through and are rejected, those that are bigger than the mesh are returned to the track along with fresh ...

Ballast maintenance for the best roadbed -

In full operation, the RM 95-800 W performs the following stages of work: excavation of ballast, pre-separation, sharpening, screening, washing and returning ballast to the track. Additionally, it is possible to have a continuous supply of new ballast, which allows more material to be added and the track geometry is measured before and after ballast bed cleaning.

Each layer plays an important role for the durability and maintenance of the track geometry. The use of natural aggregates for constructing those layers represents a significant consumption of an important non-renewable resource that is becoming increasingly scarce.

Track ballast - Wikipedia

Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track structure. Ballast also holds the track in place as the trains roll over it.

Quarrying Process And Quarry Products -

Screening is carried out at various stages in the crushing process. Screens are basically box frames into which sheets of screen meshes of the required apertures are inserted, clamped and tensioned. Screens are usually "multi-deck", i.e., two or more screen meshes are stacked vertically within the screen frame.
