Under certain premises, kinematic agglomeration of particles can be described by a model. Prior to model calculations, the condition for adherence of colliding particles had to be determined by a basic experiment. Discrete population balance simulations were then performed for various operating conditions and step responses to changes in the properties of the feed material were calculated. The calculations showed that a wide particle size distribution of the feed material furthers size enlargement by agglomeration. Measurements and calculations of the agglomeration effect were in good agreement.
