Modern hammer mills equipped with sieving capabilities are revolutionizing sand and aggregate processing lines. These systems combine high-impact crushing with precise particle size control, eliminating the need for separate screening equipment in primary crushing stages.
| Model | Capacity (t/h) | Power (kW) | Sieve Area (m²) | Max Feed Size (mm) |
|---|---|---|---|---|
| HM-800 | 50-80 | 75 | 4.5 | 300 |
| HM-1200 | 100-150 | 132 | 6.8 | 400 |
| HM-1600 | 180-250 | 220 | 9.2 | 500 |
The integrated system utilizes replaceable manganese steel hammers with tungsten carbide tips for extended wear life in abrasive materials. The multi-stage sieve design allows simultaneous production of 0-5mm sand, 5-20mm fine aggregate, and 20-40mm coarse aggregate fractions.
Q: What maintenance intervals are typical?
A: Hammer replacement every 800-1,200 hours; sieve inspection every 200 hours.
Q: Can it process wet materials?
A: Special models available with enlarged sieve openings and anti-clogging designs.
Q: Noise levels during operation?
A: Typically 85-90 dB(A) – sound enclosures recommended for urban sites.
