Abstract
A low viscosity liquid, such as a monomer, is mixed with a gel, such as a concentrated polymer in gel form. The gel and monomer flow through a cylinder containing spaced rotating discs and stationary discs mounted between the rotating discs. The rotating discs are rotated slowly, at speeds in the range of 10 to 100 rpm, so as not to degrade the polymer. The discs contain a number of apertures through which the gel and liquid flow, breaking the gel down into small particles and increasing the gel surface area exposed to the liquid, thus increasing the rate of diffusion of the low viscosity liquid into the gel.
