Description

Technical Field

[0001] This utility model relates to the field of suspension processing technology, specifically to a high-speed shearing, stirring, and sand milling combined device for suspensions. Background Technology

[0002] The high-speed shear stirring sand milling unit for suspension agents refers to a continuous or semi-continuous production system that integrates multiple key process equipment and is specifically designed for the efficient production of high-quality suspension agents (such as pesticide suspension agents SC, coatings, pigments, nanomaterial dispersions, etc.). In the existing technology, powder materials (raw materials, fillers, additives, etc.) are quickly wetted and initially mixed into liquid media (water, oil, etc.) to form a coarse slurry. The coarse slurry needs to be transported to the subsequent fine grinding equipment through a pump. However, large particles in the coarse slurry directly enter the pump, causing blockage or low efficiency. Therefore, a combined device for high-speed shearing, stirring, and sand milling of suspending agents is proposed. Utility Model Content
