The heavy-duty lever arm crusher is a cornerstone in modern sand and aggregate processing lines, designed for primary and secondary crushing of hard rocks like granite, basalt, and quartz. Its robust cast steel construction ensures durability under extreme operating conditions, with a typical capacity range of 50-800 TPH depending on model configuration.
| Model | Max Feed Size (mm) | Output Size Range (mm) | Power (kW) |
|---|---|---|---|
| HDLA-600 | 500 | 20-100 | 75 |
| HDLA-900 | 750 | 30-150 | 132 |
| HDLA-1200 | 1000 | 40-200 | 250 |
This equipment typically serves as the primary crushing unit in a three-stage system:
1. Primary crushing with lever arm crusher
2. Secondary cone crushing
3. Tertiary VSI shaping for premium sand
The hydraulic adjustment system allows real-time output size modification without stopping production, while manganese steel wear parts provide 6-12 months service life under normal conditions.
Q: What’s the maintenance interval?
A: Lubrication points require servicing every 8 hours; full inspection recommended every 500 operating hours.
Q: Can it process wet material?
A: Yes, but with 15-20% capacity reduction when moisture exceeds 5%.
A Malaysian operator achieved 650 TPH production using HDLA-1200 as primary crusher paired with two cone crushers. The plant produces:
– 40% coarse aggregate (20-40mm)
– 35% fine aggregate (5-20mm)
– 25% manufactured sand (0-5mm)
Daily operation reaches 16 hours with <3% downtime, demonstrating the lever arm crusher's reliability in tropical conditions.
