Mixer - Granulator High Shear - COMASA

FUNDAMENTALS. The tulip shape design of the bowl produces a roping action from the impeller into the high speed radically mounted chopper. The high shear forces result in intensive mixing of the components in a very short time period. Liquid aspersion over the powder bed causes solid-liquid interaction producing densification.

Once considered state of the art in high shear mixing technology, the HSD (high-speed disperser) is a familiar sight in plants across the country. But these days it plays a minor role on most process lines. It is seldom capable of more than pre-mixing (inclusion), and it generally cannot produce what we accept as a “colloidal dispersion” today.
