In this paper, a new approach for the calculation of the power draw of cement grinding ball mills is proposed. For this purpose, cement grinding circuit data including the operational and design parameters were collected from 14 industrial ball mills, ranging in diameters from 3.2 to 4.8 m. The ball loads within the mills were measured by different methods proposed in the literature and power draw of each mill were calculated. The results showed that power draw of the cement mills could accurately be predicted by the method proposed in this study.

W pracy zaproponowano nowe podejście do problemu kalkulacji zużycia energii przez młyny kulowe pracujące "na sucho", stosowane do otrzymywania cementu. Dla realizacji tego zamierzenia, zgromadzone zostały dane operacyjne i projektowe z 14 instalacji przemysłowych, które zawierają młyny kulowe o średnicy w przedziale od 3,2 do 4,8 m. Załadunek kulami każdego młyna został zmierzony przy wykorzystaniu różnych metod, proponowanych w literaturze. Zużycie energii przez każdy z badanych młynów, zostało wyliczone. Otrzymane wyniki wskazują, ze zużycie energii przez młyny do produkcji cementu można dokładnie przewidzieć stosując metodę zaproponowana w pracy.
