The grinding machine plays a critical role in modern aggregate processing, transforming raw materials into high-quality sand and gravel for construction. A typical production line includes primary crushing, secondary crushing, screening, sand-making, and washing stages.
1. Jaw Crusher: Primary crushing with a feed size up to 1500mm and output of 50-800TPH.
2. Cone Crusher: Secondary crushing with adjustable discharge size (3-60mm) and capacity up to 1000TPH.
3. Vertical Shaft Impact Crusher (VSI): Core sand-making equipment producing cubic-shaped aggregates with 5mm fineness modulus.
| Equipment | Power (kW) | Max Feed Size (mm) | Capacity (TPH) |
|---|---|---|---|
| Jaw Crusher PE1200×1500 | 160-220 | 1020 | 400-800 |
| Cone Crusher HPT300 | 315 | 240 | 200-500 |
| VSI-1140 Sand Maker | 250×2 | 50 | 200-380 |
Q: How to choose between wet and dry sand-making processes?
A: Wet process suits areas with sufficient water supply and requires less dust control. Dry process is preferred in arid regions but needs additional dust collectors.
Q: What’s the typical lifespan of wear parts?
A: VSI rotor tips last 60-120 hours depending on material hardness, while jaw plates typically work for 200-400 hours.
