Industrial expression equation for semisolid materials of solid-liquid mixture under constant pressure.

Abstract

Recent developments in expression techniques may emphasize the need for a simpler method which is easily applicable to industrial data analyses, as well as a more accurate method of analysis which may lead us to a firmer understanding of the detailed mechanisms of entire expression processes. This paper is mainly concerned with the development of a simplified equation for constant-pressure expression of thickened semi-solid materials. The equation is based on the socalled modified Terzaghi equation and also on expression experiments, and may be viewed as a semi-theoretical one. Graphical methods for determining a newly defined value of the consolidation behavior index ν and the modified consolidation coefficient Ce are also presented.
