Abstract
The moisture movement in drying clay may be expressed by the following equation:∂c/∂=∂(D∂c/∂x)/∂x
where c is moisture concentration, t drying time, χ distance in which moisture moves through clay and Dmoisture diffusion coefficient that varies with the internal moisture concentration.
By using the experimental values of the moisture diffusion coefficients on several kinds of clay, including Kibushi clay, Gairome clay and mixture of either of these with feldspar, as well as stone-ware clay, the above non-linear differential equation was solved. As a result of the analysis, the moisture distribution in drying clay could be formularized.
The validity of this treatment was attested by ascertaining the favorably good agreements between the calculated values and the experimental data concerning the moisture distribution in the above clay during a drying process.
