Abstract
A laboratory ball mill refiner for chocolatc and confectionery fat fillings consisting of vertical cylinder, equipped with a rotating shaft with arms, and filled with steel balls as a grinding medium has been used in the experiments. In this type of size reducing equipment, the feed material is comminuted between the moving media, the stirrer and the grinding chamber wall by compression and shear. The aim of the study was to examine the effect of agitator shaft speed on energy consumption of a laboratory ball mill. With constant mass of the steel balls (30 kg), the agitator shaft speed was increased from 10% to 100% of the maximum speed which coresponds to a speed of 50 rpm. The power consumption [W] was recorded upon which milling energy consumption [J/kg] has been calculated. The results were statistically analyzed using ANOVA. The increase of the agitator shaft speed, in steps of 10% to the maximum speed of 50 rpm, led to a statistical significant increase in milling energy consumption.
