Basalt is a high-hard abrasive rock widely used in high-grade road pavement aggregate, but its application in manufactured sand production is ignored by most quarry owners. Reasonable processing can turn basalt waste materials into high-value high-strength commercial sand.

Basalt has high hardness and strong wear resistance, making traditional sand making equipment prone to severe wear and low output. Ordinary crushing processes produce irregular sand grains with high flakiness rate, unable to meet high-end concrete standards.

SMP exclusive basalt sand making process adopts three-stage graded crushing: jaw primary crushing, cone laminated fine crushing and VSI rock-on-rock shaping. This process fully polishes basalt particles, reduces flakiness rate and ensures high compactness of finished sand.

Basalt manufactured sand has high strength, good durability and strong anti-skid performance, widely used in airport runways, high-speed roads and high-strength concrete projects. It creates higher economic value than ordinary limestone sand for quarries.
