In the present work, the effect of batch high shear mixer (HSM) geometries is studied on nanoparticles deagglomeration and power draw in water and aqueous glycerol solutions. The kinetics and mechanism of cluster break-up are investigated for disintegrated (less number of larger stator holes), and mesh (higher number of smaller stator holes) heads at different rotor speeds. Mesh head geometry is found to be more efficient for fines generation than disintegrated head. A bi-modal particle size distribution and erosion as dominant break-up mechanism is found. The size of the smallest fines is found to be ≈30 nm for mesh head and ≈50 nm for the disintegrated head. Z-average ranges from 180 to 310 nm for given operating and process conditions. The power draw is more in mesh head and increased with an increase in viscosity. Further, power draw increased with an increase in viscosity of continuous media and rotor speed.

在目前的工作中，研究了间歇式高剪切混合器 (HSM) 几何形状对纳米颗粒在水和甘油水溶液中解聚和功率消耗的影响。研究了在不同转子速度下分解（较大定子孔数量较少）和网格（较小定子孔数量较多）头部的簇分裂动力学和机制。网头几何形状被发现比分解头更有效地产生细粉。发现双峰粒度分布和侵蚀是主要的破碎机制。发现最小细粒的尺寸对于网头为 ≈30 nm，对于破碎的头为 ≈50 nm。对于给定的操作和工艺条件，Z 平均值范围为 180 至 310 nm。网头中的功率消耗更多，并且随着粘度的增加而增加。更远，
