Mixing technology

LED-based particle image velocimetry (PIV) images the velocity field inside a moving powder bed during blending, adding spatial resolution that static angle of repose, Hausner ratio, and shear cell tests cannot provide. Here is what that resolution can and cannot support for a process decision.

Co-processing engineers particle morphology, density, and surface structure into a single composite excipient particle. Flow function and compactibility testing show what that buys formulators on continuous direct compression lines, and where it does not.

The power or torque trace in high-shear wet granulation rises and plateaus as granules consolidate, but the signal is a supporting process indicator, not a direct particle size measurement, and its interpretation is bounded by batch size, impeller geometry, and formulation.

The same screw feeder at the same speed can deliver consistently on one powder and drift by several percent on another. The difference lies in compressibility, wall friction, and cohesion, and in how bulk density shifts as the hopper empties.
