Planetary ball milled (PBM) nanoparticle formulation method. The milling jar holds heat absorbent zirconium oxide planetary milling balls rotate about its own axis as well as in the opposite direction around a common axis of the chamber wheel. This produces the rotation of planetary balls and milling of the particles from the macro-particles ...

The Planetary Mill PULVERISETTE 5 premium line provides two stations of grinding bowls with 500 ml volume (largest capacity on the market). Each grinding bowl can be filled 1/3 part of the volume (± 170 gr sample). So, if we use two grinding bowls, the optimum capacity is about 170 x 2 = 340 g per milling process. 3.
