Ball mills are pivotal in mining and aggregate processing, transforming raw materials into finely ground sand or powder for construction applications. This article explores key equipment in a crushing-sand-making production line, focusing on ball mill technology and its integration.
A typical line includes:
1. Primary Jaw Crusher (e.g., Feed size: ≤1200mm, Capacity: 50-800TPH)
2. Secondary Cone Crusher (e.g., Discharge: ≤30mm)
3. Ball Mill (Critical for final grinding – details below)
4. Vibrating Screen (Multi-layer sieving)
| Model | Capacity (t/h) | Speed (rpm) | Power (kW) |
|---|---|---|---|
| MQG1500×3000 | 2-5 | 29 | 75 |
| MQG2100×3000 | 6-15 | 23.8 | 155 |
| MQG2700×3600 | 20-28 | 20.5 |
– Wear-resistant liners extend service life by 30%+
– Variable frequency drives optimize energy consumption
– Automated lubrication systems reduce maintenance downtime
High-frequency screens (e.g., 5mm-50mm aperture) ensure precise particle distribution meeting GB/T 14684-2022 standards for construction sand.
