* Modelled milling energy calculations workbook_2025-12-08.xlxs

This workbook calculates the modelled milling input energy for the mechano-chemical activation of clay via planetary ball mill, using the model of Burgio et al. (1991) (full reference and DOI below). It contains the input data used to calculate modelled milling input energy and activation efficiency datapoints for the associated research article. It can also be used as a stand-alone tool to calculated modelled milling input energy.

The three worksheets are:"Inputs" = contains necessary data inputs regarding milling parameters, and also performance measurements (i.e. R3 values). For original data, measured energy consumption is also listed."Calcs" = contains a series of calculation steps, to calculate individual collision energy, and total modelled milling input energy. Each calculation step is explained in the header row with regards to a specific equation in the study of Burgio et al. (1991). Input values are all linked from the ""Input"" sheet. Some cells use a LOOKUP function to automatically fill in values based on vessel size - these are linked to the ""Dropdown options"" worksheet."Dropdown options" = contains pre-defined options relating to mill and vessel parameters, specifically for a Retsch PM100 planetary ball mill.
