Hygroscopic bulk solids are substances that absorb atmospheric humidity during storage and form hydrates. „Hygroscopic“ means the property of solids, to absorb, retain or emit water and to dissolve in water.
On account of moisture migration, hygroscopic solids form clumps, crusts and layers in
open or closed containers (silos) and also in conveying and dosing systems. The loading of subsequent processes is disturbed or in the worst case even stopped entirely.
Common measures to control the behaviour of hygroscopic bulk solids are
the addition of dry air and the insulation of containers and conveying systems.
In some cases, the problems can be minimized this way. In the case of highly
hygroscopic substances these measures are not suffi cient.
Hygroscopic materials are very sensitive to the three parameters:
1. ambient humidity, 2. temperature and 3. moisture content of the material.
If one of the three factors changes, the fl ow behavior of your bulk material
