| 摘要 |
A process for producing water-absorbing polymer particles, comprising polymerization of a monomer solution or suspension, drying the resulting polymer gel, and grinding and classifying the dried polymer gel, wherein the grinding is performed by means of a multistage roll mill, the first milling gap has a width of 500 to 5000 μm, the product mass flow passing through the first milling gap is conducted through a magnetic separator to the second milling gap, and the second milling gap has a smaller gap width than the first milling gap. |
