The invention relates to a process and an apparatus for comminuting particles. The apparatus comprises at least one tube for collecting a given amount of particles, the particles forming a plug inside the tube. The apparatus further comprises at least one pressure pulse unit for generating pressure pulses, in which context the plug, subjected to a pressure pulse, is propelled from an exit aperture of the tube to hit a baffle located downstream of the tube and comprising apertures. Finally, the apparatus comprises a collection chamber following on to the baffle, in which the particles, comminuted by the impact against the baffle and passing through the apertures, are collected.
