In accordance with the prevailing national standard GB/T 14684-2022 Sand for Construction, manufactured sand refers to soil-removed rock particles below 4.75mm. Processed through professional mechanical crushing and screening, it excludes soft rock and weathered rock particles, and qualified raw materials are essential for stable output of an aggregate shaping and sand making plant. This professional processing unit has strict requirements on raw rock types for standardized manufactured sand production.
From the perspective of raw material screening, multiple qualified rock resources are suitable for the stable operation of professional sand processing systems, fully adapting to the processing needs of an aggregate shaping and sand making plant.
Natural Rocks
(1) Representative magmatic rocks: Granite, Basalt
With dense internal texture and ultra-high hardness, these magmatic rocks feature a compressive strength of 100-300 MPa. They are ideal raw materials for high-quality sand processing, perfectly matching the high-standard production demands of a professional sand making plant. The plant can fully exert its crushing and shaping performance to produce premium finished manufactured sand.
(2) Representative sedimentary rocks: Limestone, Sandstone
Boasting moderate hardness and easy crushing properties, these sedimentary rocks cause minimal wear and tear to the core processing unit of a sand making plant. They greatly optimize overall processing efficiency and create significant cost advantages for large-scale continuous sand production.
(3) Representative metamorphic rocks: Gneiss, Quartzite
High-hardness and pressure-resistant metamorphic rocks serve as high-grade raw materials for industrial and construction sand. After professional lithology screening and quality inspection, qualified metamorphic rocks can be put into asand making plant to produce compliant construction and industrial manufactured sand products.
River Pebbles
River pebbles feature a smooth surface, round appearance and no sharp corners. After being processed by professional sand making equipment, the finished manufactured sand presents uniform rounded particle shape, scientific gradation and freely adjustable fineness modulus. The reliable performance of the sand making equipment makes pebble-processed sand a perfect alternative to traditional natural sand resources.
Solid Wastes
Tailings, slag, coal gangue, construction waste and other solid wastes can be reused for sand preparation. Supported by advanced crushing and shaping technologies, the standardized sand production line efficiently converts solid wastes into qualified manufactured sand. The mature and stable operation of the manufactured sand production line solves land occupation and environmental pollution problems, realizes waste resource recycling, and brings remarkable economic and environmental benefits.
