The ball mill process is a critical method for manufacturing lead oxide, widely used in battery production. This method ensures consistent particle size and chemical composition, essential for high-performance lead-acid batteries.
1. Rotary Drum: A cylindrical vessel lined with abrasion-resistant materials (e.g., ceramic or rubber). Typical capacity ranges from 1–20 tons per batch.
2. Grinding Media: High-density alumina or lead balls (Ø 20–50 mm) facilitate efficient grinding.
3. Air Classification System: Separates fine particles (<5 μm) for optimal reactivity.
4. Temperature Control: Maintains 60–80°C to prevent over-oxidation.
| Parameter | Value |
|---|---|
| Drum Diameter | 1.5–3.5 m |
| Rotation Speed | 25–35 rpm |
| Power Consumption | 15–30 kWh/ton |
| Oxide Purity | >99% PbO |
Q: How to prevent lead dust leakage?
A: Use sealed systems with negative pressure and HEPA filters.
Q: What’s the typical production cycle?
A: 8–12 hours per batch, depending on desired fineness.
A battery manufacturer in Germany upgraded to a 5-ton ball mill system, achieving:
– 30% higher output with automated temperature control.
– 15% energy savings via optimized grinding media loading.
