Mill Selection Guide

Choosing the Right Limestone Grinding Mill

Not all limestone grinding mills are equal. The best choice depends on your target output fineness, required capacity, available budget, and end-use application. This guide will help you decide.

Quick Selection Guide

Mill Type Output Fineness Capacity Range Best Application Investment Cost Energy Use
Raymond Mill (MTW) 80 – 325 mesh 1 – 20 TPH FGD, Cement, General Low Low
Vertical Mill (LM) 80 – 600 mesh 5 – 100 TPH Large-scale Production Medium–High Low (30% less than ball mill)
SCM Ultrafine Mill 325 – 2500 mesh 0.5 – 10 TPH Calcium Carbonate, Coatings Medium Medium
Ball Mill 50 – 325 mesh 5 – 50 TPH Wet grinding, Mining Low–Medium High
MTW-Series Raymond Mill
Most Cost-Effective

Raymond Mill (MTW-Series)

The Raymond mill is the most widely used limestone grinding equipment for medium-fineness applications. Its mature technology, low investment cost, and stable performance make it the go-to choice for FGD powder, cement admixtures, and general-purpose limestone powder production.

Output Fineness
80–325 mesh (44–180ΞΌm)
Capacity
1–20 TPH (per unit)
Feed Size
≀50mm
Moisture Limit
≀6%
Main Models
MTW115G, MTW145G, MTW158G, MTW178G, MTW218G
Power Range
55–315 kW

Key Advantages

  • βœ“Low initial investment β€” ideal for startups
  • βœ“Simple structure, easy maintenance
  • βœ“Reliable operation β€” 8000+ hours/year
  • βœ“Low noise and vibration
  • βœ“Easy to adjust output fineness
Recommended for Large Capacity

LM Vertical Mill

The LM Series Vertical Roller Mill integrates grinding, classification, drying, and conveying in a single compact unit. It is the preferred choice for large-scale limestone powder production plants requiring high capacity and consistent quality.

Compared to traditional ball mills, vertical mills use 30–40% less energy while handling larger throughput β€” significantly reducing operating costs.

Output Fineness
80–600 mesh
Capacity
5–100 TPH
Feed Size
≀50mm
Moisture Limit
≀15% (with drying)
Main Models
LM130K to LM600K
Power Range
250–4500 kW

Why Choose Vertical Mill?

  • βœ“30–40% energy saving vs. ball mill
  • βœ“Large single-machine capacity (5–100 TPH)
  • βœ“Integrated drying β€” handles wet material
  • βœ“Small footprint, compact layout
  • βœ“Stable fineness control (D97 Β±5%)

Limestone Grinding Mill β€” FAQ

What is the difference between Raymond Mill and Vertical Mill?β–Ό
Raymond mills are roller-and-ring type mills suitable for 1–20 TPH capacity, best for fineness up to 325 mesh. Vertical mills (roller mills on a rotating table) are better for high capacity (5–100 TPH), wider fineness range, and have lower energy consumption. For projects over 10 TPH, vertical mills are typically more economical over their lifecycle.
Can I produce 800 mesh or finer limestone with a Raymond Mill?β–Ό
Standard Raymond mills top out at 325 mesh. For 325–800 mesh you would need a modified high-pressure suspension mill or an LM vertical mill with fine classifier. For 800–2500 mesh, the SCM Ultrafine Mill is the correct choice.
How do I determine which capacity I need?β–Ό
Calculate your daily production target first (e.g., 200 tons/day). Divide by operating hours (e.g., 20 hours/day = 10 TPH). Then add a 20% buffer. So for 200 tons/day, target a 12 TPH mill system.
What maintenance does a limestone grinding mill require?β–Ό
Main wear parts are grinding rings/rollers and classifier blades. Raymond mill rollers last 500–800 hours under normal conditions. Vertical mill tires last 8,000–15,000 hours. We supply all wear parts globally within 3–7 days.
