| 摘要 |
The invention relates to a method for increasing the bulk density and/or improving the properties and handling characteristics of those crystalline substances which normally have a low bulk density, compare with the crystal density, and poor handling characteristics due to their irregular or needle-like crystal form. According to the invention such crystals are treated ultrasonically as a dispersion or suspension in a liquid phase. The original crystals are thereby broken down in a mild manner into fragments which have a more compact form. |
