A scissor type hammer mill, mainly includes an inlet (1), hammers (2), a rotor (3), a screen (9) and a screen carriage (13) thereof, an outlet (7), a hammermill body (8), and a motor (6), and further includes a stationary hammer frame (4) and stationary hammer blades (5) provided on the stationary hammer frame (4). The stationary hammer frame is fixed on the hammermill body, and the stationary hammer blades are fixed on the stationary hammer frame, the stationary hammer blades are mounted in parallel to a rotation plane of the hammers with a distance therebetween. When the material enters into the cavity of the hammer mill, the material form a rotating material ring after being hit by the hammers, and the material is milled once again after the material ring hits the stationary hammer blade. Meanwhile, the stationary hammer blades lower the rotation speed of the material ring and change the moving direction of the material, and a component force for the movement of material towards a normal direction of the screen apertures is increased, which facilitates improving the milling efficiency, and improve the uniformity of the material to be milled. |
