Crush of materials (also known as wood powder machine), this machine broken by rough, a chronology, such as wind power transmission components, driven by the motor rotor mill high-speed operation, the machinery was able to produce high-strength materials to smash the impact force, compression force, cutting edge, friction. The aircraft can also be powered by water-cooled device, the machine is the fibrous materials, soft materials, thermoplastic materials, lightweight materials, flexibility and toughness of materials and difficult to smash a certain properties of materials have unique features
