The simplest mixing flight (Fig. 144) has smallpaddles fastened to the shaft between the threads of thescrew. These afford a gentle stirring action on the mate-rial as it is conveyed. By cutting away portions of the flights (Fig. 145) theflow of material will be interrupted at frequent intervals,by combining the cut flights with paddles (Fig. 146) a
