Principle
   When the compressed air brings the milling materials through the feeding injector to the miling chamber, the powder will be impacted, collided and milled by ultrasonic air flow from numbers of milling nozzles around the peripheral chamber. the coarser grains, separated from the grading chamber, will be cycled back to the milling chamber for further milling, the homogeneous superfine powder will be finally discharged from the port.
Features
1, Applied to the dry-type sperfine process: the high speed impact can result in not less than 2.5 mach, normally 1~10um grains.
2, The homogeneous and superfine products can result from the circular milling in the internal grading structre.
3, Applied to low-melting and heat-sensitive milling owing to the low temperature and expanded air, and also yielding the double result of blending and dispersion.
4, Advantages: rapid milling, simple structure free of movable parts, accessible maintenance and operation minimal floorage, low noise, and vibration-free.
5, High Eefficiency of milling; performing continous milling and maintaining good purity of milling products.
Application Scope
It is widely applied to superfine milling in such fields as pesticide, chemical smelt and pharmic industryies, for carbendazim, formal topsin, herbicide, silica aero gel, pigment dye and cortisone.
