DEM-Simulation der Trennkurven in Siebung und Gegenstromsichtung bei geringen Gutbeladungen

Spötter, Christian ; Elskamp, Frederik ; Hennig, Manuel ; Teipel, Ulrich ; Weber, Alfred P. ; Kruggel-Emden, Harald (2017)

Zur Abtrennung von Partikeln mit unterschiedlicher Größe sind in der Feststoffverfahrenstechnik trockene Klassierprozesse zur Herstellung von engen Fraktionen von großer Bedeutung. Um das Trennverhalten von Strömungs- und Siebklassierprozessen genauer vorhersagen zu können, wurden experimentelle Resultate mit DEM-Simulationen verglichen. Bei der Siebklassierung wurde der Einfluss der Partikelfo...

Extension of process models to predict batch screening results under the influence of moisture based on DEM simulations

Elskamp, Frederik ; Kruggel-Emden, Harald (2018)

Screening is a technical simple but still not fully understood process step, which can be used in a wide field of applications to separate bulk materials according to their particle sizes. A severe issue in screening technologies is that particles frequently prevail in moist conditions, due to effects related to the environment, the material or the process. This is often not preventable, althou...

DEM simulations of screening processes under the influence of moisture

Elskamp, Frederik ; Kruggel-Emden, Harald (2018)

In a wide field of applications, screening is required to separate bulk materials according to their particle sizes. Due to environmental, material or process related effects, particles frequently prevail in moist conditions, which is not preferred due to attractive forces altering the screening efficiency, but often not preventable. As for the design of dry screening processes detailed particl...

A strategy to determine DEM parameters for spherical and non-spherical particles

Elskamp, Frederik ; Kruggel-Emden, Harald ; Hennig, Manuel ; Teipel, Ulrich (2017)

In Discrete element method (DEM) simulations the choice of appropriate contact parameters is significant to obtain reasonable results. Particularly, for the determination of DEM parameters for non-spherical particles a general straightforward procedure is not available. Therefore, in a first step of the investigation here, methods to obtain the friction and restitution coefficients experimental...

A framework for the derivation of dynamic process models for sieving

Elskamp, Frederik (2018)

For a wide field of applications in mechanical process engineering and materials preparation technology, screening as technical simple but still not satisfactorily understood process step is well suited to separate bulk materials according to their particle sizes. Frequently, particles prevail in broad size distributions, highly non-spherical shape and under moist conditions, complicating the h...
