River pebble is a high-quality pure raw material with low impurity content and high hardness, suitable for producing high-grade aggregate and commercial sand. However, pebble’s smooth surface and dense texture bring great difficulties to crushing and shaping.

Ordinary single crushing process cannot break and shape pebbles effectively, producing many smooth unbroken particles and irregular flaky stones, unable to meet high-grade engineering standards.

SMP professional pebble three-stage crushing process adopts jaw primary crushing, cone fine crushing and VSI high-speed shaping. It fully breaks and polishes pebbles to produce high-cubicity, high-strength standard aggregate.

The finished pebble aggregate has stable quality and high compressive strength, widely used in high-rise buildings, bridge projects and high-standard concrete engineering, with high market value and profit margin.
