○The sand mill with the NBS dynamic grinding basket, compared to the domestic ordinary static grinding basket basket sand mill, adopts a completely sealed grinding basket drive. ○During operation, the basket rotates, which differs from ordinary basket sand mills in the following ways... ○In NBM grinding, the basket rotates while the internal rotor is fixed; in ordinary basket sand mills, the basket is fixed and the internal rotor rotates, preventing sedimentation and material blockage, and allowing the use of zirconium beads ≥1.2mm. ○The NBM basket sand mill generates stronger shear forces during operation, fully grinding residual materials, thereby ensuring material savings. ○Compared to ordinary basket sand mills, cleaning is more convenient and thorough. ○Compared to ordinary basket sand mills, the NBM basket sand mill is equipped with replaceable scraper plates, suitable for batch production and processing of high-viscosity products.
