Optimization of processing parameters of a ball mill refiner for
Referring to the considered chocolate recipe, before experimentation and statistical analysis, the working conditions for the ball mill used were 55 min at 70 rpm for a batch of 100 kg. However, the new optimal conditions prove to be 38.5 min at 58 rpm, again for a 100 kg batch. By making these changes, output rises from 109 kg/h to 156 kg/hThe amount of heat that is dissipated is strongly dependent on the milling parameters that influence the energy input in the milling beaker. These parameters are the frequency ν osc, the milling ball diameter d MB, the milling ball filling degree Φ MB (Eq. 1), the milling beaker size, the grinding stock filling degree Φ GS (Eq. 2) and material Temperature progression in a mixer ball mill Springer
