  • Method and device for comminuting particles
    Patent number: 7086619
    Abstract: 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.

  • Method and device for comminuting particles
    Publication number: 20040124293
    Abstract: The invention relates to a process and an apparatus (1) for comminuting particles (2). The apparatus (1) comprises at least one tube (8,8′) for collecting a given amount of particles (2), the particles (2) forming a plug (12) inside the tube (8,8′). The apparatus (1) further comprises at least one pressure pulse unit (13, 13′) for generating pressure pulses, in which context the plug (12), subjected to a pressure pulse, is propelled from an exit aperture of the tube (8,8′) to hit a baffle (6) located downstream of the tube (8, 8′) and comprising apertures (7). Finally, the apparatus (1) comprises a collection chamber (4) following on to the baffle (6), in which the particles (2), comminuted by the impact against the baffle (6) and passing through the apertures (7), are collected.
