Fluid Energy Mill
A fluid energy mill is also known as a pulverizer, micronized, or jet mill. It is used for fine grinding and close particle size control. The reduction of the particles takes place by the attrition and impact mechanism by the air or inert gas introduced through the nozzles present in the chamber. This mill is mainly used to grind heat-sensitive ...

Recent progress on hygroscopic materials for indoor
Abstract. Once in contact with the indoor air, hygroscopic materials can moderate the indoor humidity fluctuation by adsorbing or releasing water vapour, and then improve the moisture regulation and thermal management of buildings. It is desirable to explore the characterized properties of these materials about moisture buffering behaviour.

What is Hygroscopy?
A substance's ability to take in and retain moisture from its surroundings is known as hygroscopy. Hygroscopic materials are drawn to and absorb water molecules when exposed to humid air, which can cause the material to alter chemically and physically. The material's hydrophilic (water-attracting) groups or structures cause this …

Properties of Hydrates. It is generally possible to remove the water of hydration by heating the hydrate. Le Chatelier's principle predicts that an addition of heat to an endothermic reaction (heat is a "reactant") will shift the reaction to the right (product side). Heating will shift the equation of dehydration below to the right since ...
