20 Tons Per Hour Gangue Mill Pulverizer for Efficient Industrial Mineral Processing

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).

Unlocking Efficiency in Gangue Processing: The 20 TPH Challenge

In the demanding world of industrial mineral processing, handling materials like coal gangue requires robust and highly efficient machinery. Gangue, the often-overlooked byproduct of coal mining, presents unique challenges due to its variable hardness and abrasiveness. Achieving a consistent throughput of 20 tons per hour demands a mill that isn’t just powerful, but also intelligent in its design to minimize energy consumption and maintenance downtime. For operations focused on turning this waste into a valuable resource for cement production, brick making, or backfill material, selecting the right pulverizer is the cornerstone of profitability.

Key Considerations for High-Capacity Gangue Milling

When targeting a 20 TPH output, several factors come into sharp focus. First is the input size; consistently feeding the mill with material sized below 20mm is crucial for achieving optimal grinding efficiency and protecting the mill’s internals. Second is energy consumption. Traditional ball mills, while reliable, can be energy hogs. Modern mills leverage advanced grinding mechanics and classifier technology to deliver significantly higher yields with lower kWh per ton, a critical factor in today’s cost-sensitive environment. Finally, operational stability and environmental compliance are non-negotiable. A mill must run continuously with minimal vibration and be equipped with integrated dust collection systems to meet stringent regulations.

Recommended Solution: The MW Ultrafine Grinding Mill

For operations requiring high efficiency and fine output, our MW Ultrafine Grinding Mill stands out as a premier choice. Engineered for customers who need to make ultra-fine powder, this machine is perfectly suited for processing gangue into high-value additives.

  • Superior Capacity & Efficiency: With an capacity range of 0.5-25 TPH, it comfortably meets the 20 TPH target. Its newly designed grinding curves of the roller and ring enhance efficiency, offering production capacity 40% higher than jet mills and double that of ball mills, while slashing system energy consumption by 30%.
  • Precision Fineness Control: Its German-technology, cage-type powder selector allows precise adjustment of product fineness between 325-2500 meshes, achieving a superb d97≤5μm in a single pass. This is ideal for creating premium-grade gangue powders.
  • Unmatched Reliability: A key design innovation is the absence of rolling bearings and screws in the grinding chamber. This eliminates worries about bearing failures or loose screws causing catastrophic damage. External lubrication allows for maintenance without shutdown, supporting true 24/7 operation.
  • Eco-Friendly Operation: The integrated efficient pulse dust collector and muffler ensure no dust pollution and significantly reduce noise, keeping the entire milling system compliant with national environmental protection standards.

A Strong Contender: The LM Vertical Grinding Mill

For projects where the gangue feed size might be larger or extreme ruggedness is required, our LM Vertical Grinding Mill is another excellent option. Accepting feed sizes up to 70mm and offering massive capacities up to 340 TPH, it’s a powerhouse. It integrates crushing, drying, grinding, classifying, and conveying into a single unit, reducing its footprint by 50% compared to a ball mill system. It similarly saves 30%-40% in energy consumption and features a short grinding time that reduces iron content in the final product, ensuring high whiteness and purity.
