PROCESS FOR PRODUCING SUPERABSORBENT POLYMER PARTICLES

The invention relates to a process for producing superabsorbent polymer particles, comprising polymerization of a monomer solution, drying the resulting polymer gel and grinding the dried polymer gel with a roll mill, wherein the rolls of the roll mill are cleaned by reducing the feed rate to the ro...

Beschreibung
Zusammenfassung:	The invention relates to a process for producing superabsorbent polymer particles, comprising polymerization of a monomer solution, drying the resulting polymer gel and grinding the dried polymer gel with a roll mill, wherein the rolls of the roll mill are cleaned by reducing the feed rate to the roll mill, and if the deflection and/or the power consumption increases above a setpoint, operating the roll mill with reduced feed, and increasing the feed rate to the roll mill.
