A wet ball mill is a type of grinding equipment used to grind materials into fine particles in the presence of water or another liquid. If you’re referring to Limeore (limestone) wet ball milling, here’s a detailed breakdown:

Key Aspects of Limeore Wet Ball Milling
1. Purpose
– To grind limestone (CaCO₃) into fine slurry for applications like:
– Flue gas desulfurization (FGD)
– Cement production
– Soil conditioning in agriculture
– Paper, paint, and plastic industries
2. Working Principle
– A rotating cylindrical shell filled with grinding media (steel balls) crushes limestone mixed with water.
– The slurry exits through a discharge grate, ensuring controlled particle size.
3. Advantages of Wet Ball Milling for Limestone
– Higher efficiency (reduced dust, better material flow).
– Produces ultra-fine particles (<10 µm) for industrial use.
– Lower energy consumption compared to dry milling for some applications.
4. Parameters Affecting Performance
– Ball size & material: Steel or ceramic balls (typically 10–100 mm).
– Mill speed: Optimal at 65–80% of critical speed.
– Slurry density: Usually 60–75% solids by weight.
– Retention time: Longer milling = finer particles but higher energy costs.
5. Common Challenges & Solutions
| Issue | Solution |
|—|—|
| Overgrinding | Optimize milling time; use classifiers |
| Wear & corrosion | Use wear-resistant linings/stainless steel |
| Slurry viscosity control | Adjust water-to-limestone ratio |
6. Industrial Applications
– FGD systems: Wet limestone slurry absorbs SO₂ from power plant emissions.

Wet-process kilns use limestone slurry as a raw material.
Design Considerations
– Choose a mill with corrosion-resistant materials if processing acidic slurries.
– Include hydrocyclones or screens for particle size classification post-milling.
