    The ultrafine grinding of calcium carbonate was performed to synthesize GCC nanoparticles using the beads mill. Calcium carbonate was easily agglomerated in the absence of the surfactant after it was grinded even at the optimum condition: the slurry concentration of 5 wt.%, the bead size of 300 μm, and the rotor speed of 3315 rpm. The surfactant, polyacrylate, helped the grinding to reduce ...

  • Bead Mill, Principle and Applications / Apex Mill series ...

    A bead mill equipped with this method functions with beads of size of 0.1 mm or larger. This method can use smaller beads than the slit method, because the screen has a larger opening area for the slurry passage. However, in case of using beads smaller than 0.1 mm, a finer screen is needed, and it tends to clog due to coarse particles in the slurry. Clogging with this method occurs as likely ...

    A newly developed bead mill with an improved grinding media separation system allows use of beads with diameters down to 50 m. While this may not seem significant, for dispersing NanoParticles one of the methods for preventing damage to the NanoParticles is to run the machine at a slow rotor speed. A slow rotor speed reduces the separation efficiency of conventional bead mills, limiting the ...
