UNDERDRIVEN PROCESS MILL

The Quadro® Comil® Underdriven Series has the same capabilities as the Overdriven, but its compact, inline design allows for easy integration into processing environments.

The Underdriven Comil®’s smaller footprint, inline design and extremely short head height provide for easy integration into processing environments where space is limited. A large-diameter infeed and “straight through” housing promote unhindered inline product flow for quicker discharge.

Typical applications include:

  • Granulation of dry powders
  • Uniform sizing of wet granulation after high shear granulators in oral solid dosage tablet manufacturing
  • Size reducing and milling of wet or soaked products to produce liquid with wet suspended particulates
  • Powders into paste
  • Wet blending
  • Lump-free homogenous blending to precise size requirements
  • Reducing sticky agglomerates into uniform-size powders
  • Reclaiming products

Available in five models, the Comil® Underdriven is scalable in capacity from several ounces (grams) to 35,000 lb/hr (15,900 kg/hr). The innovative spacerless design allows for quick changeover of impellers and screens. Plus, specialized tooling is available to meet all process requirements.

BENEFITS

  • Low RPM / Low NoiseLow speed design applies an inherently gentle action to the product
  • Low Energy / Low HeatLimited or no heat is generated, making the Underdriven the perfect choice for milling heat-sensitive products
  • 360° Positive Product Discharge maximizes throughput as entire screen surface is utilized within milling chamber
  • Choke / Flood FedRecommended for most Comil® applications; however, this is product/process dependent
  • Low DustEliminates the need for dust collection/explosion retention devices; environmentally friendly
  • Uniform Particle SizeAbility to achieve desired granularity
  • Higher CapacityUp to 50% more capacity than conventional mills due to a larger infeed diameter
  • Spacerless TechnologyNo spacers required for optimizing impeller/screen gap
  • Extremely Short Head HeightFits tight space requirements
  • No Metal-to-Metal ContactLess wear on moving parts
  • Easy-Clean DesignLow maintenance
  • Scalability accuracy and repeatability from R&D to full production

FEATURES

  • Stainless steel construction throughout
  • Accurate PSD (Particle Size Distribution) controllability
  • Milling efficiencies ensure highest percentage of product on-spec (10% – 30% improvement over other conical milling technologies)
  • Predictable and repeatable scalability from R&D to production
  • Reduced heat generation at high throughput capacities
  • Efficient product processing for nearly 100% product recovery
  • Superior containment, with OEL levels under 1 µg/m3
  • Inline tri-clamp design for simplified process installation
