It uses to help determine the grinding media optimal size must be loaded into the ball mill for proper operation ensure The calculation formula is below: B – the grinding balls diameter, mm; A – the correction factor (for grinding balls Up to 50% of V B,total can be taken over by the substrates in addition to 30% for the total milling ball volume Scaleup factors of 15 and 11 were realized considering the amount of substrates and the reactor volume, respectively Beside technological parameters, variables which influence the process itself, t reaction and rpm, were investigated also Variation of those allowed to finetune the reaction Scaleup of organic reactions in ball mills: process For all types of chocolate, the quadratic relationship for “time × particle size” and cubic relationship for “time × water activity” were determined For dark chocolate, the quadratic relationship was detected between time and moisture content It was seen that this relationship was cubic for Effect of ball‐mill process on some quality parameters of
