Abstract
Apparatus is described that is useful for making a stable aqueous dispersion of a complex alkali metal-aluminium-silicate which is soluble in hydrochloric acid. The apparatus comprises a mixing tube, at least two inlets through which aqueous streams can pass into one end of the tube, one of the inlets being for the supply of the bulk of the water for the process at a pressure of at least 40 psi, an outlet at the other end of the tube, and stationary means within the apparatus for causing the aqueous streams to adopt a generally helical path and to mix with one another with shear, and for causing the product leaving the outlet to be at a pressure of atmospheric pressure or less and which is at least 40 psi below the pressure in the inlet of the bulk of the water.
