In addition to the limits specified in as 2758.7, the aggregate crushing value of the ballast material for class h track when determined in accordance with as 1141.21, for the fraction of material passing the 53.0 mm test sieve and retained on 37.5 mm test sieve.
In simulation of railway ballast behaviour using discrete element method (dem), it seems to be necessary to take into account the crushing and the abrasion of grains. nowadays, two approaches have been used in discrete modelling. the first approach represents each grain as an assembly of smaller units with cohesive contacts between them 1, 2.
Introduction of ballast crusher when it comes to the ballast,it refers to the heavy material, such as gravel, sand, concrete or coarse stone, placed low in a vessel to form the bed of a railroad track or road to improve its is widely used in road, railway, highway order to improve its performance,it usually needs to be crushed and processed firstly.
Finding the right crusher. cobalt management needed a crusher and screener to crush and size the thousands of tons of ballast needed, and the transportation constraints required the contractor to consider not only production requirements, but also the load sizes of the equipment to ensure the railroad could transport it.
During the daily operation of railway, particle breakage is a key process contributing to degradation, thus spct was employed to find out the crushing property of single particle, and the test device is shown in fig. this test, the sample was crushed by stress controlling method, i.e. after located the slag, the loading plate was moving with a certain force.
The microdeval abrasion test procedure results in some particle crushing that overlaps the laa test specification. a better practice is to separate ballast particle wear and crushing characteristics in a ballast specification by using both the laa value and the ma value separately (klassen et al. 1987).
Largersize and irregular morphologycreated bythe crushing process. this paper presents a detailed investigation of the factors affecting μ for a granite ballast. due to the relatively low numberof particles, dem analyses of railway ballast or rock fill are closer to achieving an accurate 1:1 modelling.
