Stone Crushing for Expressway Construction

The fast development of the expressway construction in China brings more opportunities to stone crushing machinery manufacturers. However, stone quality is highly required in expressway construction. For example, the mechanical strength, durability and chemical stability of stones; the stone's particle size, grading, particle shape, the content of 0.075mm particle etc.

Seeing from the problems existed in the opened expressway, stone crushing industry still has some inadequacies. For example, most of the particle size of stone is coarser then required and the content of flaky particle is out of limits.

Usually, after being crushed and screened, the stones will be in the following size: 0-5mm, 5-10mm, 10-15mm, 15-20mm, over 20mm and smaller than 40mm. Those stones' quality for expressway construction shall meet the GB14685-2001 standard. After being crushed, the hard and brittle rock is easy to form flaky particle, and also the crushers(jaw crushers) which crush stones by squeezing is more likely to produce flaky shape particle size then crushers(such as impact crusher, vertical shaft impact crushers) that adopt impact crushing method。
