Limestone Grinding Mill: Efficient Solutions for Fine Powder Processing

Limestone, a widely used industrial mineral, is essential in various industries such as construction, agriculture, environmental treatment, and manufacturing. However, to meet the specific needs of each application, limestone must be finely processed into different powder grades. This is where a reliable and high-performance limestone grinding mill becomes critical.

Why Limestone Powder is in High Demand

Limestone powder, depending on its fineness, serves diverse purposes:

  • 100–200 mesh: used in construction materials and road base.
  • 200–400 mesh: widely used in desulfurization in power plants.
  • Above 800 mesh: applied in plastics, rubber, coatings, and even pharmaceuticals.
  • Over 1250 mesh: ideal for producing high-end functional fillers and ultra-fine chemical products.

To produce high-quality limestone powder with consistent particle size distribution and purity, advanced grinding technologies are essential. This article explores how XZM Ultrafine Mill and MTW Trapezium Mill from our company offer the perfect solution.


XZM Ultrafine Mill: High-Precision Limestone Powder Processing

🔹 Unmatched Fineness and Efficiency

Our XZM Ultrafine Mill is designed specifically for ultra-fine grinding applications, capable of producing powders ranging from 325 to 2500 mesh (D97≤5μm). It is an ideal solution for industries that demand superfine limestone powder, such as paints, plastics, PVC, and advanced fillers.

Model Options: XZM800 to XZM1680

Input size: ≤20mm

Output fineness: 325–2500 mesh

Capacity: 0.5–25 tons/hour

🔹 Key Advantages

✅ Energy-Saving and High Capacity

Compared with traditional jet mills, XZM Ultrafine Mill can deliver double the output with 30% lower energy consumption, thanks to intelligent control systems and advanced design.

✅ Precision Classification

The vertical turbine classifier ensures clean particle separation, eliminating oversized particles and ensuring consistency in final product quality.

✅ Robust Construction

With specially treated rollers and rings, the mill boasts an extended service life. The bearing-free grinding chamber ensures stable performance with minimal maintenance.

✅ Eco-Friendly Design

XZM Ultrafine Mill meets global environmental standards with a pulse dust collector and noise control chamber, achieving noise levels ≤75 dB and excellent air cleanliness.

🔹 Applications in Limestone Powder Production

  • Ultrafine calcium carbonate
  • Industrial fillers for paints and polymers
  • High-end limestone-based pharmaceuticals
  • Advanced environmental applications (e.g., flue gas desulfurization)

MTW Trapezium Mill: Reliable Medium-Fineness Grinding

For limestone applications requiring medium-fine output (30–325 mesh), our MTW Series Trapezium Mill provides an excellent balance of efficiency, durability, and energy savings.

Input size: ≤50mm

Output fineness: 30–325 mesh

Capacity: 3–45 tons/hour

Model Options: MTW110 to MTW215G

🔹 Technical Highlights

✅ Innovative Blade Design

The curved shovel blade ensures even material spreading and minimizes wear, reducing maintenance costs.

✅ Arc-Shaped Air Duct

Redesigned for higher air velocity and reduced resistance, this feature improves material transportation and grinding efficiency.

✅ Integrated Cone Gear Drive

MTW uses a compact and efficient cone gear system with 98% transmission efficiency, reducing installation space and energy loss.

✅ Heavy-Duty Construction

From its wear-resistant volute casing to a rigid base, the MTW mill is built for long-term industrial usage with low maintenance.

🔹 Suitable Limestone Applications

  • Construction-grade limestone powder
  • Desulfurization agents for thermal power plants
  • Agricultural lime (soil pH adjustment)
  • Cement industry additives
