dirt. If we confine our remarks to cleaning of stone ballast it is because data is available for this type of ballast, while very little is known as yet of cleaning other ballast materials, except slag, which can be considered to be comparable with stone. When To Clean . Ballast should be cleaned when fouled enough to prevent proper drainage.
This paper presents effect of ballast form and packing on its crushing strength and fragmentation behavior using the discrete element method (DEM). Bubblepack algorithm was chosen for this study to generate the ballast with different forms and packing conditions. Two key parameters, namely the bubblepack ratio ( $$rho $$ ρ ) and overlapping distance ( $$Phi $$ …
crusher. When it was time to move to another source of rock, the crusher would simply travel along the road to the next quarry where crushing would quickly resume. Excavators were also used to feed the crusher in the Powell River area. A 26 000-kg excavator and a 31 000-kg excavator were used at the Sliammon and Lois Lake sites, respectively.
The analysis aimed to show the trends of the stress state of a concrete sleeper during a conventional loading in the case of a crushed stone ballast bed.

Crushed Stone: The Unsung Mineral Hero: Crushed stone is often looked upon as one of the lowliest of commodities, however it is used for such a wide variety of purposes in so many industries that it should be elevated to a position of distinction. It is the geologic commodity upon which almost everything is built. The word cloud above shows just a few of its diversity of uses.
Several types of rock crushers are commonly used for crushing ballast stone. The specific crusher machine used may vary depending on factors such as the scale of the operation, the desired output size, and the available resources. Here are some commonly used ballast crushing equipment: 1. Jaw Crusher

The study showed promising results using aggregate shapes rather than sphere-shaped ballast stones. Dahal and Mishra [18] simulated ballast particle breakage by calibrating the crushing criteria in the DEM simulation by particle crushing laboratory test. Polyhedral ballast shapes were compared with spherical shaped ballast stones.
