Description

Technical Field

[0001] The utility model belongs to the technical field of grinding equipment, and in particular relates to an ultra-high molecular polyacrylamide grinding device. Background Art

[0002] Polyacrylamide is a general term for acrylamide homopolymers or polymers copolymerized with other monomers. Polyacrylamide is widely used in oil extraction, papermaking, water treatment, textile, medicine, agriculture and other industries. Before processing, polyacrylamide is mostly a crude block product and needs to be ground into a fine powder. At this time, the material needs to be ground by grinding equipment. Most of the existing grinding equipment has a fixed structure, which is not convenient for adjusting the diameter of the material produced by different grinding. After searching, it was found that the application number "202320059438.1" disclosed "a polyacrylamide dry powder grinding device", which recorded "a polyacrylamide dry powder Grinding device", the grinding distance between the fixed grinding block and the moving grinding block is adjusted during use to adjust the size of the grinding particles, but the grinding device still has certain shortcomings during use: when grinding the block-shaped polyacrylamide material, the grinding efficiency is low only by the fixed grinding block and the moving grinding block. At the same time, some of the ground materials will not meet the size during grinding. The grinding device does not have a screening function during use, which affects the material grinding effect. Based on this, we propose a grinding device that can efficiently grind the polyacrylamide material and screen the ground product. Utility Model Content
