River pebble is a high-quality raw material for manufactured sand production with high hardness, pure texture and no harmful impurities. However, pebble’s smooth surface and dense texture bring great difficulties to crushing and shaping, easily producing unqualified needle-shaped sand products.

Traditional single-stage crushing process cannot effectively shape river pebbles, resulting in poor sand grain shape and low market price. Only professional multi-stage crushing and shaping technology can produce high-standard commercial manufactured sand from river pebbles.

SMP mature river pebble sand making process adopts jaw crusher for primary coarse crushing, cone crusher for medium crushing and VSI sand making machine for final shaping. The rock-on-rock crushing principle fully polishes pebble particles to form round and uniform sand grains.

Matched with professional washing and powder separation equipment, the whole line strictly controls mud content and fineness modulus of finished sand. SMP pebble sand making projects are widely distributed in river basin areas, providing high-quality commercial sand for local construction markets.
