外文摘要：Both dynamic cutters installed on the shaft and fixed cutters installed on the shell has realized to form the high-pressured superimposition produced the high dynamic pressure and the static pressure due to the Reynolds effect during process of high-speed rotation, which forms high pressure required by super velocity centrifugal grinding, and raw material of the sawdust or fibrous fragments can be stricken and cut into the wood powders which are in line with granularity of requirement for power generation through treble percussion effect including percussion between the particles and the dynamic and fixed cutters, percussion between particles and particles, and percussion between the particles and the shell. Simultaneously, the disintegrator has realized integration between the main motor and the main spindle, which has many characteristics such as contact construction, low noise and slight vibration. This machine is possible to realize 3 kind of granularity that could be selected.
