The Comprehensive Guide to Crushing and Sand-Making Equipment in the Aggregates Industry
The global demand for crushed stone, sand, and gravel continues to rise, driven by infrastructure development, urbanization, and construction activities. As a key player in the aggregates sector, crushing and sand-making equipment forms the backbone of material processing, transforming raw rock into high-quality construction materials like concrete aggregates, road bases, and railway ballast.
To achieve a daily output of 500 metric tons of copper ore (or similar hard rock), a well-designed crushing and sand-making production line typically includes:
1. Primary Crushing (Jaw Crusher or Gyratory Crusher)
– Handles large feed sizes (up to 1,500 mm) with high reduction ratios.
– Output: Coarsely crushed material (~250–300 mm).
2. Secondary Crushing (Cone Crusher or Impact Crusher)
– Further reduces particle size to 30–60 mm for optimal grinding/sand-making feed.
3. Tertiary Crushing & Sand-Making (Vertical Shaft Impact Crusher – VSI)
– Produces finely graded sand (0–5 mm) and cubical aggregates.
– Ideal for high-value manufactured sand applications.
4. Auxiliary Equipment
– Vibrating screens (multi-deck for precise grading).
– Conveyors and dust suppression systems.
Estimated Investment Range:
1. How to minimize dust in crushing plants?
– Use mist cannons, enclosed conveyors, and baghouse filters.
2. What’s the lifespan of crusher wear parts?
– Jaw plates: 3–6 months; Cone mantles: 2–4 months (depends on abrasiveness).
3. Can one VSI crusher handle 500 T/D alone?
– No—typically requires a staged setup with pre-screening for efficiency.
