[0002] Polyacrylamide is a linear high molecular polymer which can be divided into non-ionic, anionic and cationic types according to its structure. Anionic types are mostly hydrolyzates. Polyacrylamide is widely used in papermaking, mineral processing, oil production, metallurgy, building materials, sewage treatment and other industries. Polyacrylamide is widely used in oil production as a lubricant, suspending agent, etc. It is an extremely important oilfield chemical.

[0003] The larger the mesh size of polyacrylamide, the easier it is to dissolve. Therefore, domestic polyacrylamide manufacturers with higher quality are pursuing particle refinement. Therefore, during the polyacrylamide grinding process, it needs to be ground repeatedly. The wet polyacrylamide will adhere to the feed box and absorb new polyacrylamide particles. The new feed in the feed box will not enter the grinding seat for grinding. Therefore, we proposed a polyacrylamide grinding device that is easy to feed to improve the above problems.
