Modeling of Mixing of Toners with DEM and Continuum Models
Abstract:Computation of mixing of toners in mixers with complex geometries requires extensive computational effort. Continuum models are more practical for such problems in comparison with DEM models due to the size of the problem. Use of continuum models requires appropriate material properties for modeling such flows. Discrete element model is used to determine the material properties for the continuum model. A simple problem is solved first by both DEM and continuum models. By comparing the results of these to solutions, material properties of the toner for continuum model are determined. In this paper, a summary of the formulations is provided and examples of a simple experiment of toner flow are illustrated.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
