roll mill limeore capacity

The capacity of a roll mill for processing limeore (limestone) depends on several factors, including:

1. Roll Mill Type (e.g., two-roll, three-roll, or four-roll mill).
2. Roll Diameter & Width – Larger rolls handle higher throughput.
3. Feed Size & Moisture Content – Finer and drier feed increases capacity.
4. Gap Setting Between Rolls – Adjusting the gap affects output fineness and capacity.
5. Material Hardness & Abrasiveness – Limestone is relatively soft (~3 Mohs), allowing higher throughput than harder materials.
6. Motor Power & Speed – Higher power and RPM increase capacity.

Estimated Capacity Range for Limeore in Roll Mills
| Roll Mill Type | Capacity Range (TPH)* |
|—————|———————-|
| Small Lab Roll Mill | 0.1 – 1 TPH |
| Industrial Two-Roll Mill | 5 – 50 TPH |
| Large Four-Roll Mill | 50 – 200+ TPH |

*TPH = Tons per Hour (varies based on conditions).

Key Considerations for Maximizing Capacity:
– Pre-crushing limeore to a smaller feed size (e.g., <50mm) improves efficiency.
– Adjusting roll pressure & gap to balance fineness and throughput.
– Maintaining roll surfaces to prevent wear from abrasion.

For an exact capacity calculation, manufacturers like FLSmidth, Metso, or ThyssenKrupp provide specifications based on your specific limestone properties and desired output size.
