A modern crushing and sand-making production line integrates primary crushing, secondary crushing, sand shaping, and screening processes. Key equipment includes jaw crushers, cone crushers, impact crushers, vibrating screens, and sand makers (e.g., VSI crushers). The process begins with raw material feeding, followed by coarse crushing (<150mm), fine crushing (<50mm), and sand shaping (<5mm).
1. Jaw Crusher: Primary reduction (e.g., feed size: ≤1200mm, output: 10-350mm).
2. Cone Crusher: Secondary crushing (e.g., capacity: 50-1000 t/h, discharge: ≤30mm).
3. VSI Sand Maker: Produces cubic-shaped sand (e.g., input: ≤50mm, output: 0-5mm with fineness modulus adjustable).
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE600×900 | 50-160 | 75 |
| Cone Crusher | HPT300 | 120-400 | 315 |
| VSI Sand Maker | S8-1145 | 150-500 | 250×2 |
Vibrating screens classify materials into multiple sizes (e.g., 3-4 decks with mesh sizes 5mm/10mm/20mm). High-frequency screens improve efficiency for fine particles (<3mm).
Key parameters: Particle shape (flakiness index <15%), gradation (meets ASTM C33), and silt content (<3%). Moisture content is controlled below 5% for concrete applications.
Q1: How to reduce dust in the production line?
