Hydrogel Preparation characterization and applications

Preparation of hydrogel based on acrylamide acrylic acid and its salts by inverse-suspension polymerization and diluted solution polymerization have been investigated elsewhere. Fewer studies have been done on highly concentrated solution polymerization of acrylic monomers which are mostly patented en produced acrylic acid-sodium acrylate superabsorbent through concentrated (43.6 wt

The mill product can either be finished size ready for processing or an intermediate size ready for final grinding in a rod mill ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill.
