The hammer crusher is a critical machine in sand and aggregate processing, designed to crush materials with high compressive strength into smaller particles. Its robust construction and high-impact crushing mechanism make it ideal for limestone, granite, and other hard rocks.
– High Crushing Ratio: Typically 10–25, reducing large feed sizes (up to 1,200mm) to 25mm or smaller.
– Adjustable Discharge: Grate bars control output particle size.
– Durable Hammers: Made from high-manganese steel for extended service life.
| Model | Feed Size (mm) | Output Size (mm) | Capacity (t/h) | Power (kW) |
|---|---|---|---|---|
| PCΦ400×300 | ≤200 | ≤25 | 5–10 | 11 |
| PCΦ800×600 | ≤350 | ≤25 | 15–30 | 55 |
| PCΦ1000×800 | ≤500 | ≤35 | 40–80 | 132 |
In a typical sand production line, the hammer crusher works alongside vibrating feeders, jaw crushers (for primary crushing), vibrating screens, and sand makers. For aggregate plants, it often follows cone crushers to refine material further.
Q: How often should hammers be replaced?
A: Depending on material hardness, every 200–400 operating hours.
Q: Can it handle wet materials?
A: Yes, but with reduced efficiency; moisture content should ideally be below 15%.
Q: Noise levels?
A: Approximately 75–85 dB; enclosures are recommended for urban sites.
