Beneficiation enhances the economic value of mined ores by improving their quality and reducing impurities. In sand and aggregate production, it ensures consistent particle size, better gradation, and higher purity—critical for construction and infrastructure projects.
A typical sand and aggregate production line includes:
1. Primary Jaw Crusher: Processes large raw materials (e.g., granite, basalt) with a feed size up to 1,500mm and output of 50–300mm.
2. Secondary Cone Crusher: Further crushes materials to 20–60mm for optimal shaping.
3. Vertical Shaft Impact Crusher (VSI): Produces finely graded sand (0–5mm) with high cubicity.
4. Vibrating Screen: Classifies aggregates into multiple sizes (e.g., 0–5mm, 5–10mm, 10–20mm).
