Abstract
As it was necessary to clarify the micromeritical nature of common salt in the process of the quantitative analysis on the caking of salt, some characteristics were studied from the view-point of void which was considered the most important factor affecting the caking of salt. The effect of the pressure on the void was given by the following formula:
ε=ε0e-βP
And the following formulae were derived from the above:
The data about a bulky pile of common salt were studied on the base of the above formulae.
Also, the permeability through the closest-packed layer of different samples was tested, and the shape of particle was found to have a great influence on the permeability.
ε: void h: depth ε0: initial void ρ: apparent density β: compressing coeff. ρ∞: specific density P: pressure
