Abstract (en)
[origin: EP0300402A2] The subject of the invention is a method for obtaining extremely small particles to below 1 mu m by pulverising, which is characterised in that the particles are suspended in a liquid in order to increase their mass and a droplet-shaped amount of the suspension taken from the suspension is made to impact. The method is intended in particular for use in pulverising using a largely rigid plate on which particles of a particle stream are made to impact.
