Spiral jet mill micronisation. Dec's spiral jet mills consist of a flat, cylindrical grinding chamber using a venturi injector which creates an initial negative pressure to convey the particles into the central chamber at subsonic speed. A series of specially designed nozzles increases the acceleration to supersonic speeds (300–500m/s) in a ...
