Basalt is the most ideal raw material for high-speed highway, airport runway and high-grade pavement aggregate, thanks to its high hardness, compression resistance and wear resistance. However, basalt’s high hardness and strong abrasiveness bring great challenges to ordinary crushing equipment, causing severe wear, low output and poor particle shaping effect.

Ordinary impact crushers are not suitable for basalt processing, resulting in excessive flaky particles and unqualified pavement aggregate. Only professional hard rock crushing configuration can meet the strict standards of high-grade road engineering. SMP targets basalt’s physical characteristics to design exclusive three-stage crushing and shaping process.

The process adopts C6X jaw crusher for bulk basalt primary crushing, multi-cylinder hydraulic cone crusher for high-efficiency laminated fine crushing, and VSI vertical shaft impact crusher for final rounding shaping. This configuration effectively reduces basalt aggregate flakiness rate below 2%, fully meeting international high-standard pavement requirements.

SMP basalt crushing EPC solutions are widely applied in high-speed road infrastructure projects in Russia, Central Asia, Eastern Europe and Southeast Asia. The high-cubicity basalt aggregate produced significantly improves road durability and anti-skid performance, winning wide recognition from engineering contractors.
