A small-scale sand and gravel plant requires careful planning to balance efficiency, cost, and output quality. Below is a breakdown of essential equipment and processes for producing high-quality aggregates.
1. Jaw Crusher: Primary crushing of raw materials (e.g., granite, basalt). Typical model: PE-400×600, with a feed size of 340mm and output of 16-64t/h.
2. Cone Crusher/Impact Crusher: Secondary crushing for finer particles. Example: PF-1214 Impact Crusher, capacity 70-130t/h.
3. Vibrating Screen: Multi-layer screening (e.g., 3YK1548) to separate sizes (0-5mm, 5-10mm, 10-20mm).
4. Sand Maker (VSI Crusher): Produces artificial sand with adjustable fineness modulus (e.g., VSI7611, output 60-150t/h).
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE-400×600 | 16-64 | 30 |
| Cone Crusher | PYB900 | 50-90 | 55 |
| Sand Maker | VSI7611 | 60-150 | 110 |
| Screening Machine | 3YK1548 | -80 | 15 |
