The dry raw mix is pneumatically blended and stored in specially constructed silos until it is fed to the pyroprocessing system. In the wet process, water is added to the raw mill during the grinding of the raw materials in ball or tube mills, thereby producing a pumpable slurry, or slip, of approximately 65 percent solids.
