Abstract
The shear gap between a rotor and a stator in a colloid mill is adjusted by translating the stator with respect to the rotor, preferably by moving the stator along a helical path about the rotor, thereby moving the stator's surface closer to or further from the rotor's surface (and altering the shear gap therebetween). Helical slots are provided in the casing about the stator, with members extending from the stator through the slots, whereby the members can be grasped and rotated about the casing to move the stator. Channels allowing circulation of buffer fluid are provided about the stator and rotor to deter ingress of the fluid being processed into junctures between components of the colloid mill.
