Abstract (en)
[origin: EP2527040A2] The method involves supplying particles as grinding stock in a grinding chamber (5) of the jet mill (1). The grinding stock is grinded to fine particles by grinding as superheated water vapor or technical gas is used as operating fluid. The surface active additive is supplied to the grinding stock for stabilizing the generated fine particles. The additive is mixed with the grinding stock before grinding. The additive is directly introduced in the grinding chamber. The operating fluid contains hydrogen or helium as technical gas. An independent claim is included for a jet mill with an operating fluid supply unit.
