A good stone ballast is generally procured from hard stones such as granite, quartzite, and hard trap. The quality of stone should be such that neither is it porous nor does it flake off due to the vagaries of weather. Good quality hard stone is normally used for high-speed tracks. This type of ballast works out to be economical in the long run.

The Stone Crushing Process. The process of stone crushing involves several stages, each with specific objectives. The first step is feeding the raw materials into the stone crusher, which can be done by hand or using loaders. The materials are then transported to the crushing chambers, where they undergo crushing to reduce their size.

The crushed stones you see alongside railroad tracks are what is known as ballast. Their purpose is to hold the wooden cross ties in place, which in turn hold the rails in place.
Nevertheless, the process is relatively simple: locate or create (minimal) breaks in the stone, remove the stone using heavy machinery, secure the stone on a vehicle for transport, and move the material to storage. A flow diagram of typical quarrying operations is shown in Figure 1. Figure 1. Process flow diagram for limestone quarrying operations.
