Abstract

In order to form separate particles from a flowable mass, the flowable mass is fed through a pipe and extruded through holes formed along a longitudinal axis thereof. The pipe is oscillated by an agitator in a direction transversely of the longitudinal axis to cause the extruded mass to be sheared-off in the form of particles. Stop members can be positioned adjacent respective sides of the pipes to be contacted by the pipe and thereby define change-of-direction points for the pipe during its oscillation. The agitator may include piezoelectric ceramics attached to the stop members.
