Discrete model for analysis and design of grinding mill ...

2006-5-1  The axial dispersion model was used by Mihálykó et al. as a starting point to develop a discrete computer model for computer-aided analysis and design of open-circuit continuous grinding mills. The grinding process was modeled by the fundamental grinding equation, and the effects of both the transport and the kinetic parameters on the size distribution of the product were analyzed, but classification to separate fines and to recycle large particles to the mill was not included into the model.

The structural design of the agitator mill has a number of advantages: The horizontal orientation ensures homo-geneous distribution of grinding media in the grinding chamber. Thus, start-up of the mill with product is unproblematic. The highest fl ow rates can be set without pressure build-up.

Optimising design of continuous grinding mill

2005-2-1  The grinding circuit is modelled by a discrete mathematical model describing the axial mixing and breakage of particles in the mill and a possible time delay in the recycle line. The design problem is formulated as a nonlinear programming task in which the convective flow velocity and the axial dispersion coefficient of the ground material are selected as design variables.
