Coal mining operations in Tuli Nagaland generate substantial waste rock and overburden, which can be repurposed into high-quality sand and aggregates using modern crushing and screening technology. Below is a tailored solution for processing coal-associated materials into marketable construction materials.
A typical setup includes:
1. Primary Jaw Crusher (e.g., JC5460): Processes large-sized coal waste (≤800mm) to ≤200mm. Capacity: 300–500 t/h.
2. Secondary Cone Crusher (e.g., HPT300): Further reduces material to ≤50mm. Capacity: 200–350 t/h.
3. Tertiary Impact Crusher (e.g., VSI6X1150): Produces 0–5mm sand with high cubicity. Capacity: 150–250 t/h.
4. Vibrating Screens: Multi-deck screens (3YK3070) classify outputs into 0–5mm, 5–10mm, and 10–20mm fractions.
| Equipment | Model | Feed Size | Output Size | Capacity (t/h) |
|---|---|---|---|---|
| Jaw Crusher | JC5460 | ≤800mm | ≤200mm | 300–500 |
| Cone Crusher | HPT300 | ≤200mm | ≤50mm | 200–350 |
| Sander Maker | Trituradora de impacto VSI6X1150 | ≤50毫米 | 0-5毫米 | |
