Basalt Processing Technology

Basalt is the good source of cast stone. Cast stone can be got by melting, crystallizing, annealing the basalt. It is harder and more wearable than alloy, more erosion-resistant than lead and rubber. The Moh's hardness of basalt is within 5-7 and the content of SiO2 reaches 45%-52%. So as for the crushing technology, instead of using impact crusher, cone crusher is often used for middle and fine crushing at the second and third stage.
