<jats:title>Abstract</jats:title><jats:p>In the present study, a new separation function T(x,α’,β) for the steady‐state screening process is presented. This new grade efficiency T(x,α’,β) presented here is a function of particle size x, separation sharpness α’, and the newly introduced separation efficiency β. With this new efficiency function, the screening classification process can be described exactly. Especially in the fine and coarse material ranges, a very good correlation of the calculated function with the measured values can be observed. A comparison of the grade efficiency function with separation sharpness α’, separation efficiency β, and only with the measure for separation efficiency has shown that the new grade efficiency T(x,α’,β) allows a significant improvement in the characterization of the stationary screen classification process. When compared with other models, the new model of the grade efficiency T(x,α’,β) shows a significantly higher correlation with the measured values and is therefore very well suited to describe a grade efficiency for the stationary screening process.</jats:p>
