vertical limestone grinding mill

Working Principle

The motor rotates the grinding table via a reducer. Raw material enters at the center while hot air flows in from the intake. Centrifugal force moves material to the table edge, where it is crushed by rollers in annular grooves.

Crushed material is carried upward by airflow; coarse particles fall back for regrinding. Fine powder passes through a classifier—oversized particles return, while qualified powder exits with airflow and is collected as product.

Moisture is removed through contact with hot gas during conveying, ensuring final powder meets required moisture levels.

Custom Model Classification

Flue Gas Desulfurization (FGD) Limestone Vertical Roller Mill: Specifically designed for desulfurization processes in power plants, efficiently producing limestone powder with a particle size range of 22–180 μm.

Ultra-fine Vertical Roller Mill (HLMX Series): Equipped with a secondary classifier, achieving a finished product fineness of up to 3 μm and a maximum capacity of 40 t/h. Ideal for processing fillers and chemical additives.

Key Advantages

1. Energy-saving – Power consumption reduced by 35%–50% vs. ball mills, thanks to material-bed grinding that minimizes over-grinding.

2. High drying capacity – Integrated hot air system handles feed moisture up to 15% (hot air up to 450°C), eliminating separate dryers.

3. Fine & stable product – Dynamic classifier with adjustable rotor speed controls fineness from 3–22μm; closed-circuit system ensures narrow particle size distribution.

4. Low maintenance cost – High-chromium alloy wear parts last >30,000 hours; metal wear ≤5–15 g/t; hydraulic roller system with auto-adjustment reduces manual work.

5. Compact & clean – Requires 50%–70% less space than ball mills; negative-pressure operation ensures zero dust leakage; noise ≤75 dB(A), 20–25 dB lower than ball mills.

6. Smart operation – PLC touchscreen control for real-time monitoring, automatic feeding, and remote diagnostics via Internet.
