Super absorbents are polymers that are used as an absorbent of water and aqueous solutions mainly in diapers. The real difficulty in screening super absorbents comes from the particles itself. Super absorbent particles are extremely misshaped and makes it difficult for individual particles to find the screen hole openings. The other major problem with screening super absorbents is the fact that the particles are very friable. This means that too much energy will actually break up the material and this is not desirable.
