|Abstract: ||A method for pulverizing natural organic substance into nano-scale fibrous material including steps: Cleaning raw material of natural organic substance from grease and drying it with common equipments. Coarsely pulverizing said prepared natural organic substance with common mechanical milling machine into small piece of a particle size around 500 m in length. Mixing said coarse particles with pure water as a suspension and finely pulverizing it by a professional ultrasonic crusher into fine piece of a particle size smaller than 20 m both in diameter and length. Feeding said fine particles contained suspension with high pressure into a nano collide machine for dividing said suspension into two parts to collide with each other and generate vibration to cause said raw material into nano-scale size. Drying said nano particles with a common spray dryer if dry nano-scale organic substance fibrous particle is in need.|
