The effect of processing parameters on energy

2015-2-10  The consumption of energy in the process, espe-cially in the process where the large part of it is energy required for grinding, should be kept at the lowest possible level. The agitator shaft speed significantly influences the energy consumption of the ball mill. Therefore, the agitator should be run at lowest possible speed to meet the degree of particle size reduction that is needed (or any other
