The utility model discloses a vane blade for an HP-type coal mill. The vane blade is characterized in that the cross section of the vane blade is in a wing shape, and comprises a front edge, a rear edge, an upper chord line, a lower chord line, the maximal thickness and a wing chord, wherein the length of the wing chord is chord length 1; the wing shape is a symmetrical wing shape; the maximal thickness c is 21%-24% of the chord length; the distance a from the maximal thickness to the front edge is 55%-60% of the chord length; the radius r of the front edge is 8%-10% of the chord length; the thickness of the end surface of the rear edge is 10%-15% of the chord length; an included angle X is formed between the end surface of the rear edge and the wing chord; and the part between the maximal thickness of the upper chord line and the end surface of the rear edge is a straight line. The vane blade has the advantages that the flow rate of air of a vane is increased by the characteristic that the flow rate of fluid flowing through the wing-shaped surface is increased; the flow resistance of air through the vane is reduced; the front and back differential pressure of the vane is reduced; turbulent flow is avoided; the air-outlet efficiency of the vane is relatively high; meanwhile, an air throttle ring in the prior art is concealed; the packing phenomenon of pebble coal on the vane and the ignition hazard are fundamentally removed; and technical support is provided for burning high-volatile brown coal of the coal mill.
