Introduction Nanoparticles are increasingly used in novel formulations due to the resulting superior properties and performance. The intermediate or final product may be in the form of a nanoparticulate dispersion, in which case achieving a fine and stable dispersion is a key process target. Whilst powder incorporation can be achieved using a stirred tank, the subsequent stage of deagglomeration typically requires a more power intensive device, such as an in-line rotor-stator. In this project, the dispersion performance of an in-line rotor-stator, Ytron ZC1, which can be used for both powder addition directly into the rotor-stator head and potentially for deagglomeration, has been investigated. Power characteristics, suction performance and incorporation have been the subject of previous presentations. The part of the study presented here had the objective of establishing the deagglomeration performance of the YtronZC1 in-line rotor-stator. The effects of power input, residence time, powder concentration and gap width in the teeth on the mechanism and kinetics of deagglomeration have been investigated.
