Quadro's Comil type Underdriven

Based on the same technology as the Overdriven Comil, the Underdriven models provide some unique advantages. The inline (straight) design enables larger product throughput and unhindered product flow. Complete with a low housing height for compact installation. The Underdriven models apply spacerless technology to obtain optimum impeller/screen gap for best process performance. The Underdriven units are available in 3 models (U10, U20, U30) with capacities ranging from 0 to 55,000 lb./hr (0 to 25,000 kg/hr).

Innovative Technology for Size Reduction:

Higher capacities
  • Up to 50% more capacity than conventional mills due to a larger infeed
         diameter.

    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 falls 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 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 speed selection.
