Was patchy structure, pore structure and structure of general almond.

In the construction of high grade highway, railway, airport runway, basalt is the stone in the best material, its advantages are can not be replaced by other stone, it is wear-resisting, eat less water, electric performance is poor, compression and strong, crushing value low, strong corrosion resistance, adhesion of asphalt and other quality characteristics, the international that basalt is the development of high-speed rail and highway transport the best aggregate cornerstone.

Basalt crusher is necessary for the mining machinery equipment, common stone crusher are jaw crusher, mobile crusher, counterattack crusher, impact crusher, composite crusher, hammer crusher, vertical crusher.
