Description

technical field

[0001] The invention relates to a nano particle ultrasonic atomization grading device and a method thereof, belonging to the technical field of powder grading. Background technique

[0002] Powder particle classification is one of the key process steps in powder processing. The demand for nano-scale powder preparation continues to increase, and the graded particle size has developed from macro-scale to micro-scale and nano-scale. The particle size of nanopowder ranges from 1 to 100nm, and it has the characteristics of high surface activity and low bulk density. It is widely used in biochemistry, nanomedicine, semiconductor material preparation, organic printing, etc., and has good commercial application value. The particle size of powder prepared by mechanical ultrafine grinding method is usually between nanometer and submicron. For example, after several hours of grinding, the particle size of silicon powder is usually between 0.05 and 1 μm. If you want to...
