Ball-milling Following the protocol of Hempel et al. (2020a), the particle size of bulk IND was reduced by ball milling at 30 Hz for 1 min in a cold room (5 °C) using an oscillatory ball mill (Mixer Mill MW400, Retsch & Co., Haan, Germany) with a pair of jars (25 mL) and two stainless steel balls (12 mm in diameter) for each jar.

The effect of high-frequency oscillatory type ball-mill treatment on the structure and antiobesity activity of konjac flour was investigated. The grain size of konjac flour changed from 657.3 μm (d50) to 23.7 μm (d50) after 4 h of treatment. The structural change of the konjac flour with different grain size was characterized by using X-ray diffraction (XRD) differential …

The path of the balls and particles is determined by many factors, including vibrational speed, amplitude, curvature of the sides of the mill chamber wall, horizontal motion of the mill, and charge contact with the upper surface of the mill chamber. The balls gyrate around the chamber wall, sometimes traveling horizontally in a spiral path.

A novel top-down procedure for synthesis of stable passivated nanoparticles uses a one-step mechanochemical process to form and passivate the nanoparticles. High-energy ball milling (HEBM) can advantageously be used to mechanically reduce the size of material to nanoparticles. When the reduction of size occurs in a reactive medium, the passivation of the nanoparticles …

An oscillatory ball mill is a vibrating ball mill that oscillates in a horizontal direction. Because there are no oscillations in the vertical direction, a two-dimensional view of the main part of an oscillatory ball mill can be considered in the xy-plane (Cartesian coordinate system) containing the arm and the grinding jar ( Fig. 1 a ).
