The Mechanism of Filter Pressing and Slip Casting

Abstract

The literature on the mechanism of the slipcasting process is reviewed. An equation is developed to give a quantitative description of the rate at which the clay layer is deposited from the slip in the filter‐pressing and slip‐casting processes. Certain factors in the equation can be evaluated by the application of the Kozeny equation. Agreement between the calculated and observed rates of solids deposition is satisfactory and confirms that the mechanism in both processes is simple dewatering.
