STABLE HIGH SOLIDS SLURRIES OF STRUCTURED CLAY MATERIALS AND PROCESS FOR THE MANUFACTURE THEREOF

摘要

A stable high solids structured clay slurry is manufactured by a process which comprises the sequential steps of forming a high solids slurry by mixing a structured clay material with water in a first stage mixing step under conditions which promote particle to liquid contact and which substantially prevent interaction between the structured clay particles, terminating the first stage mixing and then, in a second stage mixing step, mixing the high solids slurry under conditions which are different from the first stage mixing conditions and which promote substantial interaction between the structured clay particles.
