This work intended to describe drum screens in the light of new results of study on these machines carried out recently at the Technical University of Łódź. The latest designing achievements in this area have also been taken into account. It seems that modern drum screens should be high-speed machines, i.e. such in which high speed factor (the ratio of drum angular velocity to rotation velocity) should range from 0.8 to 0.9, and not from 0.3 to 0.4, as is the case in the currently operating screens.
