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
