Process and apparatus for reducing the size of particles of a flowable material. The process includes a stream of the fluid and the particles that is fed under pressure. The particles are subjected to expansion forces in a first dimension while they are simultaneously fed through at least one continuously narrowing constriction. While the particles in the fluid are conveyed through the narrowing constriction, they are subjected also to expansion forces in a second dimension. The apparatus may include a device which pressurizes the fluid and its particles which are fed through at least one inlet into a space. This space is defined from two sides only by at least one pair of opposing walls. Thus, the walls form a narrowing constriction up to a gap of smallest cross-section. This gap communicates with the outlet.
