ABSTRACT:
A device for producing suspensions of finely divided matter includes a dispersion mill of the type with a slotted rotor and stator. The stator has chamfers on the leading edges to permit fluid flow from the rotor into the stator which is longer in duration, of greater volume, and along a path resulting in an impact angle of 90 degrees. The impact angle generates stagnation forces of a magnitude that results in cavitation when the fluid accelerates away from the impact zone. Subsequent discharges of fluid from rotor to stator slot creates increased ambient pressure around the vapor cavity accelerating cavity collapse and generating high pressures through accelerated collapse and through reentrant jet effects. Shock waves are transmitted locally which disintegrate particulates such as cells.
