Traditional construction waste recycled aggregate has defects such as rough surface, high mortar adhesion and low strength, resulting in low product grade and only applicable to low-grade road filling projects, with low economic benefits.

Improving the quality of recycled aggregate is the key to upgrading waste recycling projects. The old single crushing process cannot remove surface mortar and impurities, restricting the high-value utilization of construction waste resources.

SMP professional recycled aggregate quality improvement technology adopts secondary crushing, surface peeling shaping and multi-stage impurity removal process. The optimized impact crushing and screening system removes residual mortar, brick residues and sundries on the surface of waste stones.

The processed high-quality recycled aggregate has uniform particle size and high strength, which can be used for medium-grade concrete production and high-standard road base projects, greatly improving the market value and profit space of construction waste recycling projects.
