Abstract (en)
[origin: US4476071A] Granular solid particles, in particular hard, comminuted material of any given shape, are kept continuously in relative movement in a funnel-shaped container by means of a stream of liquid whereby they are rounded off. The rounded-off particles are suitable as filler material for wear-resistant coatings.
