Abstract: A new concept of investigation on granular material grinding process using a multi-ribbon blender is demonstrated. A new approach
of mathematical description of this process is presented using the Shannon’s entropy definition for random processes. The
analysis of experiments was carried out employing the probability size distribution variation with the time of grinding process.
The investigations reported in this work provide useful insight into the granular material grinding process. Moreover, the
proposed informational description may be used to quantify the progress of this process whose importance in plant design and
process optimisation, according to other experimental works, appears to be underestimated.
Keywords: grinding process - informational entropy - multi-ribbon blender
