Abstract
A method and apparatus for manufacturing a submicron polymer powder from solid polymer bodies or coarse particles, preferably of polytetrafluoroethylene powder, wherein powder is ground into fibrous particles in the first stage and is disintegrated into submicron particles by aerodynamic treatment in the second stage, where a gas-particle mixture is subject to the effect of centrifugal forces and suction forces acting in the direction opposite to the centrifugal forces, a pulsating sign-alternating temperature field generated by a pulsed supply of liquid nitrogen, turbulent forces of vortexes, and aerodynamic forces that cause alternating compression and expansion of the gas-particle mixture.
