The drying capacity of the vertical mill is strong, and the waste heat of the kiln can be used to dry the raw materials with a moisture content of 8% or higher. The air ring area, the air ring angle and the height of the dam ring can be adjusted according to the working conditions.

Looking downward from the top, a turbine with a Savonius rotor would look like two spoons facing opposite directions and linked at the center to the rotor axis (creating an 'S' shape in cross section (Fig. 20.14)).Due to their curvature, the drag of the concave surface is higher than the convex surface, forcing the rotor to turn when the cups are exposed to wind (Mathew, 2006).

tional ball-mill systems, high-pressure grinding rolls in every kind of design types and their various combinations with ball mills and, of course, VRMs vertical roller mills. All of these systems treat the material to be ground differently, in that the actual grinding needed to achieve the desired character-istics varies from one to the other.
