  • What is ballast ? Types, Functions, Characteristics, Size

    Types of Ballast. Different materials used as ballast in India are broken stone, gravel, sand, ashes, cinders. And sometimes soft aggregates like moorum, kankar, overburnt and broken brickbats, blast furnace slag and selected earth. 1. Broken Stone. This is the best material for ballast and almost all important tracks are provided with stone

    Different Types Of Aggregate And Their Uses

    - Ballast is the coarsest form of aggregate available. How is it made? Typically made of crushed stone, although ballast has often consisted of less suitable materials such as burnt clay. Is it for you? If what you need is either concrete mixes, filling gaps in hard core, as a concrete component, pathways, or major footings, then this is for you.

    Selecting the Right Crushing Equipment Agg-Net

    Intermediate (secondary) crushing The purpose of intermediate crushing is to produce various coarser fractions, eg basecourse, or to prepare the material for final crushing. If the intermediate crusher is used to make railway ballast, product quality is important. In other cases, there are normally no quality requirements, although the product must be suitable for fine crushing. In most cases, the objective is

    Aggregates » Railway Recycling

    Network Rail receives over 1m tonnes of spent track ballast at our Aggregate Handling Depots per annum. This means we have a lot of aggregate for sale. The majority of this material is recycled through screening, crushing and washing processes that make it suitable for re-use in both rail network projects, DIY projects and the construction industry as a whole.
