Abstract
A basic differential equation for expression of pasty mixture of finite thickness, consisting of fine solid particles and liquid, is solved by method of moments.
By this method, expression coefficient E(e), a function of void ratio e, is determined only from data of expressed liquid volume Vepd vs. time Θ in the earlier half period of the expression and the ultimate liquid content emin. Time dependence of liquid content distribution in the mixture e (CV, Θ) is calculated using the E(e), and the relation of Vepd vs. Θ is calculated by integration of the e(CV, Θ).
Pasty mixture of TiO2-water was used for this study, and a fairly good coincidence between the observed relation of Vepd vs. Θ and the calculated one was confirmed.
