摘要： The invention discloses an improvement applicable to systems in which amineral, such as kaolin crude is fed into a shear mixing device and high energy, with asuspending fluid such as water and in which dispersing agents are added to said mixingapparatus at a flow rate to produce a suspension whose solids content is not more than72% by weight. Applying heat to the fluid within the mixer mixing zone, or before itenters therein, in order to elevate the temperature of the slurry to at least 10 ° C. Heatcan be added directly or indirectly. In Figure 1, the material (4) is fed by a conveyor belt(13), so as to fall in the mixer (6) where a rotor (14) carries out the kneading of the rawmaterial in the presence of aqueous components. The water (1) is introduced via an inletduct (17) and a dispersing agent (3) is fed independently via the pipe (16). Steam (22) isinjected directly into the mixing chamber at the mixer via a line (20) opening into thelower portion of said mixing chamber (24).
