Figure 4 shows the 800 TDG with gas distribution unit. When the product leaves the grinding zone (A), a permanent upstream air flow transports the almost milled powder towards the classification area (C). Material that is fine enough can enter the classifier wheel and moves with the air into the separation filter.
