U6-S12. Packed (tapped) density (On-site) OUTSTANDING

Packed (tapped) density

Each particle of a solid material has effectively the same true density regardless of size or shape, but more or less geometric space is occupied by the material according to the relative particle-particle cohesion and mechanical interference. That is, the apparent bulk densities of powdered, granular or flaked materials are highly dependent on the manner in which the particles are packed together. Furthermore, handling or vibration of particulate material causes the smaller particles to work their way into the spaces between the larger particles. The geometric space occupied by the powder decreases and its density increases; ultimately no further natural particle packing takes place without the addition of pressure and maximum particle packing is achieved.
The equipment for this purpose is Autotap (Quantachrome Instruments).

Customer benefits

The equipment provides tapped density measurements of powders for customers who need to characterise this property and add value to their materials.

Target customer

Universities, public research organisations and industries.
