Abstract:
1. An apparatus for comminution of polymer gel, said apparatus comprising: a static cutting unit including a cutting screen for obtaining gel strands, wherein the cutting screen is formed of pretensioned members, and the static cutting unit includes a stiffening grid for supporting the cutting screen; a dynamic cutting element, positioned downstream of the static cutting unit, for cutting the gel strands formed by the static cutting unit into particles of uniform size and shape; and a feed unit for feeding the polymer gel to the static cutting unit in a shape-stable state, wherein the feed unit is operable to feed the polymer gel batchwise or continuously, and the dynamic cutting element comprises at least one tensioned wire supported in a movable support frame such that movement of the support frame effects back and forth movement of the tensioned wire.
