Difference of compressibility

There are big differences between the fabrics when it comes to compressibility. For example, the hardness, consistency and compressibility of amorphous powders differ compared to crystalline powders.

The density and hardness of crystalline powders is high, making the powder less compressible under pressure.

Amorphous powders, on the other hand, are more compressible. At the same time, there is also a greater chance of clumping under pressure, for example in the bottom of big bags.

Tips to achieve maximum packaging properties

When there is little space between the particles, there is a good arrangement and we speak of an optimal packaging property. Shaking, dropping or vibrating the powder will help the particles settle in and fill the spaces in between. This temporary compression effect ensures a better arrangement, which increases the packaging property. This means that more mass can be packed per volume. The amount of interstitial space normally decreases as the powder size decreases. The smaller the particles, the easier they can fill a void. Above a certain powder size, the amount of space in between remains constant. This works in reverse when the amount of fine particles is so high that all possible empty spaces are already occupied. So there must be a balance between the different sizes of the powders. This good powder size distribution ensures a minimum of intermediate spaces and thus a good packaging property.
