pulverizing hygroscopic material

Hygroscopic Material - an overview ScienceDirect

Straw is a hygroscopic material, which means that it will adsorb water vapor from the air and absorb liquid water when exposed to a suitable source. Adsorption is the process by which water vapor molecules are held on the surface of a material through polar attraction. Materials that store water vapor in this way are termed hydrophilic.

Hygroscopy - an overview ScienceDirect Topics

Using these techniques hygroscopic materials can be characterised by increased water sorption at high RH values. The experimental method can be extended to examine the mechanism of the water sorption process. At 90% RH, the target RH is then taken down to 0% RH so that each equilibrium desorption step mirrors the adsorption steps.

Hygroscopic Material - an overview

If a hygroscopic material is pneumatically conveyed, it may absorb moisture from the air that is used to convey the material and become very cohesive, and have poor flowability as a result. Although the specific humidity of the air will reduce if it is compressed isothermally beyond the saturation point, its relative humidity will increase and is likely to be 100% after compression.

Hygroscopy - an overview ScienceDirect Topics

Materials that pick up less than 1%, under the same conditions are regarded as non-hygroscopic [34]. A hygroscopic material may deliquesce (where adsorbed water starts to solvate molecules of the solid) if the critical RH of the solid is lower than that of the surrounding atmosphere ( Figure 9 ).
