Titanium dioxide with a particle size of approximately μm is widely used as a pigment because of its notably high refractive index and significant scattering properties. To achieve optimum scattering in the visible range (400700 nm), it is important to obtain a narrow particle size distribution, between μm and μm. TiO 2 particles are usually finely ground to the desired ...

4. Comparison of horizontal and vertical types. The orientation of the mill is an item for selection of the type of bead mill. There are two types of bead mills: horizontal and vertical. Since the centrifugal force acting on the beads is tens to hundreds times the gravity, the influence of gravity is small enough to be ignored.
