  • Attrition Mills Kinergy

    Attrition Mills. An Attrition Mill is used for reducing “no bake” bottom sand lumps to “grain size” of minus 20 mesh or green sand to small particles. Sand is dumped into the rear hopper section. The lumps rub on one another and produce “fine” grains which can convey up a steep incline.Chapter 18. Feed Milling Processes,The mill also includes the processes of attrition and impact, although these actions are limited if the material is easily reduced by cutting and the screen limiting discharge has large perforations. The mill consists of a rotating shaft with four attached parallel knives and a
