ABSTRACT A novel process for preparing particles of polymer gel prepared by polymerizing an aqueous solu- tion of water-soluble vinyl monomers which comprises breaking the polymer gel into particles with a breaker device wherein the gel is cut into strips by a pair of rollers having a plurality of annular projections or grooves on their surfaces, the rollers rotating in the opposite direction to each other to engage to each other and to cut off the gel fed between the rollers, and the strips are then cut into particles by a combi- nation of a fixed cutting blade and a rotating cutting blade. The obtained gel particles are further pulver- ized into fine round or spherical particles in a ver- tical type cutter comprising at least one vertically fixed cutting blade and a rotary cutting blade ar- ranged rotatably and vertically, a clearance being provided between an edge of the rotary cutting blade and an edge of the fixed blade.
