Quadro® Comil® / Products
Comil Underdriven
Innovative Technology For Size Reduction
Higher Capacities
- Up to 50% more capacity than conventional mills due to a larger infeed diameter.
- Optimum performance when plug/choke fed (Unit does not require additional volumetric feeder equipment).
Spacerless Technology
- No spacers required to optimize impeller/screen gap.
Ideal For Process Integration
- Low dust, low noise, low temperature.
- Standard sanitary connections and transitions for integration.
Extremely Short Head Height
- Fits into tight space requirements.
Easy-Clean
- Ultra-sanitary gear box design.
- Minimal surface area and obstruction of product flow.
Versatility
- Various screens and impellers with many specialized tools are available to accomplish any process requirement.

Principle of Operation
| The infeed product is introduced into the conical screen chamber. A rotating impeller imparts a vortex flow pattern to the incoming material. The material is then forced to the screen surface by centrifugal acceleration, ensuring continuous delivery into the "action zone" between the screen and impeller. In the "action zone," the material is sized or size reduced and instantaneously discharged through the screen openings. The finished product is discharged at the bottom of the milling chamber. Particle size can be optimized by screen, impeller and/or speed selection. |

- Capacities are based on standard pharmaceutical placebo with 3% crystalline cellulose (LMC).
- Capacities may vary acordingly based on product characteristics, particle granulometry, inlet and discharge conditions. Consult your local representative or Quadro for product testing.
- For some products, capacities may reach the following higher limits: (a) 15,000 lb/hr (6,800 kg/hr), (b) 35,000 lb/hr (15,900 kg/hr)
- U3 model is generally designed for lab and research purposes.
