High Efficiency Four-Roller Limestone Grinding Mill for Fine Powder Production

We provide a wide range of mills — including Raymond mill, trapezoidal mill, vertical mill, ultrafine mill, and ball mill, obtained ISO9001 international quality certification, EU CE certification, and Customs Union CU-TR certification. Suitable for processing minerals such as limestone, phosphate, quicklime, kaolin, talc, barite, bentonite, calcium carbonate, dolomite, coal, gypsum, clay, carbon black, slag, cement raw materials, cement clinker, and more.

The discharge range of these mills can be adjusted to meet specific processing needs, typically from 80-400 mesh, 600-3250 mesh, and can achieve the finest particle size of up to 6000 mesh(D50).

Revolutionizing Fine Powder Production with Advanced Grinding Technology

In today’s industrial landscape, the demand for high-quality fine powders is growing exponentially across sectors like construction, chemicals, and food additives. Meeting this demand requires cutting-edge grinding technology that combines efficiency, precision, and environmental sustainability. Our MW Ultrafine Grinding Mill represents the pinnacle of such innovation, specifically engineered to transform limestone and other minerals into ultra-fine powders with unmatched consistency.

Why Choose Four-Roller Technology?

Traditional grinding mills often struggle with energy inefficiency and inconsistent particle size distribution. The four-roller configuration in our MW series addresses these challenges head-on:

  • Enhanced Grinding Efficiency: The synchronized rotation of four rollers against the grinding ring creates a cascading crushing effect, ensuring uniform particle size reduction.
  • Material Layering: Multiple rollers allow for progressive grinding stages, preventing over-processing of already fine particles.
  • Thermal Management: Distributed grinding pressure reduces localized heat buildup, preserving material properties.

Key Features of Our MW Ultrafine Grinding Mill

Designed for 0.5-25 tph capacity with input sizes up to 20mm, this system stands out through:

  1. Precision Particle Control: German-engineered cage-type powder selector enables adjustment between 325-2500 meshes (d97≤5μm achievable).
  2. Maintenance-Free Design: Elimination of rolling bearings and screws in the grinding chamber prevents mechanical failures.
  3. Eco-Conscious Operation: Integrated pulse dust collector and silencer maintain dust levels below 10mg/m³ with noise under 75dB.
  4. Energy Savings: Consumes only 30% of the energy compared to jet mills for equivalent output.

Applications Beyond Limestone

While optimized for limestone, this versatile mill processes:

Material Category Examples Target Industries
Carbonates Calcite, Dolomite Plastics, Paper
Industrial Minerals Barite, Talc Paints, Cosmetics
Energy Materials Petroleum Coke Fuel Additives

Complementary Solution: LUM Ultrafine Vertical Grinding Mill

For operations requiring even finer powders (up to 2500 mesh) from smaller feed sizes (0-10mm), our LUM Ultrafine Vertical Grinding Mill offers:

  • Taiwanese roller technology with 30-50% energy reduction
  • Reversible roller structure for simplified maintenance
  • PLC-controlled multi-head powder separation

Technical Superiority in Action

The MW mill’s working principle exemplifies engineering excellence:

  1. Material enters through central feed and spreads centrifugally
  2. Progressive grinding across four roller stages
  3. Airflow carries powder to German-designed separator
  4. Precision classification with oversize particles recycled

This closed-loop system ensures zero material waste while maintaining consistent product quality batch after batch. With digital control interfaces, operators can fine-tune parameters in real-time to adapt to varying material characteristics.

Commitment to Sustainable Production

Beyond performance metrics, our grinding solutions prioritize environmental responsibility. The MW series achieves:

  • 98.5% dust capture efficiency
  • 30% lower carbon footprint versus conventional mills
  • Full compliance with EU Industrial Emissions Directive
