Furthermore, the influence of the type of mill was investigated, including reactions performed in different planetary and mixer ball mills, in a stirred media mill, and with a mortar mill. Comparisons with the other solvent-free synthetic routes showed that ball milling is an effective way of performing the reaction with low energy intensity.

The results obtained from the study show that ball‐mill process can be successfully modeled in the main chocolate varieties for the particle size change and moisture removal which are among the main objectives of the use of this processing step. Therefore, they have potential to use in the relevant production areas.
In the current study, the process performance (grinding efficiency) of grinding inorganic powder into fine particles using wet grinding with a stirred ball mill was investigated by examining how specific surface areas of ground products are affected by the process parameters.
Our goal is to measure the size distribution of the milled product, in-process and in real-time, without the need for sampling or dilution. FBRM (Focused Beam Reflectance Measurement) was used for real-time measurement of particle dimensions in a real process environment. Milling was carried out in a stirred media mill.
The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.
