The coal mining industry in South Africa relies heavily on efficient transportation systems to move raw materials. However, the by-products of coal mining, such as sandstone and shale, can be repurposed into high-quality sand and aggregate for construction. A well-designed crushing and sand-making production line is essential to transform these waste materials into valuable resources.
1. Primary Jaw Crusher: Processes large chunks of sandstone (≤1200mm) into smaller pieces (≤350mm). Key model: PE-900×1200 with a capacity of 220-450 t/h.
2. Secondary Cone Crusher: Further crushes material to ≤50mm. Model: HPT300, output 200-250 t/h.
3. Tertiary Impact Crusher (Sand Maker): Produces fine aggregates (0-5mm). Model: VSI6X1263, capacity 150-200 t/h.
4. Vibrating Screen: Multi-layer screening for precise grading (e.g., 3YK3070).

Q1: How to reduce dust in the production line?
A: Install dust suppression systems at transfer points and use water sprays.
Q2: What’s the lifespan of crusher wear parts?
A: Jaw plates last ~6 months; cone crusher liners ~8 months under normal conditions.
Q3: Can the line process wet materials?
A: Yes, but moisture content should be <10% to
