Simply stated, aerodynamic stall occurs when the blade's angle facing the oncoming wind becomes so steep that it starts to eliminate the force of lift, decreasing the speed of the blades. Active stall control - The blades in this type of power-control system are pitchable, like the blades in a pitch-controlled system.
Oct 01, 2003· One method of controlling the particle size from a coal mill is the use of a vertical spindle mill static classifier, see Fig. 1.The vertical spindle mill static classifier resembles the well-known cyclone, except that it has a much shorter 'barrel' or cylindrical section, an inner pipe located on its central axis, a different path for the 'rejected' particles and an inlet flow which ...
