The new High Efficiency Comil® U21 represents a revolutionary approach to size reduction. By reinventing and redefining conical milling, Quadro®has achieved an unprecedented particle size distribution optimization for improved powder homogeneity and flowability.

The High Efficiency Quadro® Comil® U21 achieves what no other conical mill is capable of doing: an extraordinary decrease in unwanted “fines” or “overs,” which translates into tighter PSDs by 25% to +50%, yet still within validated particle size distributions high and low limits. Plus, the U21 provides up to 60% capacity increase.

The conical screen chamber of the High Efficiency Quadro® Comil® U21 is designed to supply a vortex flow pattern to the in-feed product by means of a rotating impeller. As product travels into the “action zone” by continuous centrifugal acceleration, it passes through precisely defined unique-geometry screen hole apertures.

As a result, material is sheared through the screen at optimum tangential velocities, creating uniform size reduction rates and producing narrow, consistent and repeatable particle size distributions.
