Hummer vibrating screens are widely used in USA’s crushing and sand-making production lines for efficient grading and separation of aggregates. These robust screens excel in handling various materials, from limestone to granite, ensuring precise particle size distribution for construction-grade sand and gravel.
– Heavy-duty steel construction with reinforced frames
– High-frequency vibration motors (typically 900-1500 RPM)
– Adjustable amplitude (3-8mm) for different materials
– Multi-layer designs (2-4 decks) with polyurethane or wire mesh screens
– Capacities ranging from 50-800 TPH depending on model
| Model | Screen Size (mm) | Layers | Power (kW) | Capacity (TPH) |
|---|---|---|---|---|
| HV-1230 | 1200×3000 | 2-3 | 7.5×2 | 50-150 |
| HV-1545 | 1500×4500 | 3-4 | 11×2 | 200-400 |
| HV-1860 | 1800×6000 | 3-4 | 15×2 | 400-800 |
In a typical setup, Hummer screens work after primary/jaw crushers and before cone crushers or sand makers. They separate oversized materials (>40mm) for recrushing while directing properly sized aggregates to different stockpiles. For manufactured sand production, they ensure final product meets ASTM C33 specifications.
Q: How often should screen panels be replaced?
A: Typically every 6 12 months depending on material abrasiveness.
Q: What maintenance is required?
A: Monthly lubrication of bearings and regular tension checks for screen meshes.
Q: Can they handle wet materials
