When paving roads and railways, people would use coarse sand and gravel as ballast. The ballast is usually the super-granite which has strong rigidity. As for its crushing technology, very often, the jaw crusher would be used at the first stage of crushing and cone crusher would be used at the second or third stage. 100-150tph Crushing Line

Ballast is coarse aggregate with particle size normally ranging from 10 mm to 65 mm. Upon repeated train loading, ballast deteriorates in the form of either continuous abrasion of sharp corners or size degradation, which have been reported as the fundamental cause for the instability of railway tracks. In this study, the splitting behavior …
