This study compiles the recorded values of instantaneous voltage and current levels in a three-phase system designed to power-supply the laboratory roller mixer. The measurement technique is outlined and relevant algorithms are provided for computing apparent power, active and reactive power, as well as power factors cos\fi and tg\fi. Calculation data reveal some fluctuations of power demand in the function of the amount and moisture of the synthetic system sand being mixed. Conclusions were drawn concerning the potential compensation of reactive power demand by an investigated roller mixer.
