Because the wood density is relatively low, therefore, the spindle wood powder machine low speed centrifugal to free state, in order to decrease the wood powder was air, increasing spindle speed and give a long wood powder to meet the rail, each knife angle thirty degree tilts, the increase of cutting pressure, when the machine. A super powder machine equipment selection wind system planning: wood powder movement has a certain action, movement speed, high quality of its kinetic energy is large, gravitational potential is large, when they were changed the direction of movement of the force, is not the same because of inertia will constitute the motion track is not the same, and the implement the same number of graded sieving.
The wind power selection system is mainly are classified by the spiral separator, that is, the larger diameter spiral separator is adopted, which can make the centrifugal force of the particles less, so that finer particles into the sorting equipment, while the larger particles are settling. The height of the straight part of the separator is properly added, and the function is to extend the circular movement of particles in the classification area, which is conducive to the settlement of particles. Increasing the inlet speed of air flow and strengthening the centrifugal action, the spiral separator can separate the wood powder about 300 meshes.
