Description: One pre owned Quadro Comil, Model U20, Stainless Steel. Approximate capacity up to 4250 pounds an hour. 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.
