Abstract
Disclosed is a grinding mill including a roller press configured to comminute grinding stock, a first conveying mechanism in communication with the roller press and configured to transport downstream at least one of fresh grinding stock or grinding stock comminuted by the roller press, and a static sifter disposed downstream of the first conveying mechanism and configured to sift at least one of the fresh grinding stock or grinding stock comminuted by said roller press. The static sifter includes a sifting stock inlet disposed in an upper sifting space, and sifting gas inlet disposed in a lower sifting space, and an aeration plate separating the upper sifting space from the lower sifting space. The aeration plate also permits sifting gas to pass there through from the lower to the upper sifting space. The static sifter also includes oversized material outlets disposed in each of the respective upper and lower sifting spaces.
