Description
Agglomerator
Dynamic
The agglomerator unit [54] calculates the output particle size distribution
based on simplified population balances that don’t account for particle
attrition. The unit parameters offer the option to select different
agglomeration kernels as well as to choose from a list of available solvers
from the solver library
Bunker
Dynamic
The bunker unit is modeled with an ideally mixed holdup. The target mass
of the bunker is set via unit parameter. The output mass is controlled by an
internal PID-controller to match the user-defined target holdup mass
Crusher
Steady state There are multiple comminution laws for different applications available:
• Bond’s power law, originally developed for comminution in ball and rod
mills [7]
• Comminution for cone crusher, applying a selection function developed
by King [28] and a breakage function presented by Vogel and Peukert
[62]
• A general population balance model including a solid holdup, applying a
selection function presented by Austin and Luckie [6] and a breakage
function shown by Austin [5]
Crystallizer
Dynamic
The crystallizer unit models simultaneous crystal growth and aggregation
in a seeded batch crystallizer, presented by Kovacevic and Briesen [30]. To
solve the population balances it uses a Monte-Carlo method
