Claim Text:
1. Apparatus for producing shear-thinned slurry, comprising: a thickening apparatus having a wall, a shear-thinning apparatus, at least one first conduit for feeding slurry to be shear-thinned from the thickening apparatus to the shear-thinning apparatus, said first conduit having an end connected to the wall of the thickening apparatus, at least one second conduit for returning the shear-thinned slurry from the shear-thinning apparatus to the thickening apparatus, said second conduit having an end connected to the wall of the thickening apparatus, and at least one discharge line connected to the second conduit; wherein the first conduit and the second conduit are positioned essentially concentrically to each other at least in the ends connected to the thickening apparatus, said conduits forming openings in the wall of the thickening apparatus, and wherein the apparatus further comprises a controllable restriction element arranged in the second conduit and located downstream of the discharge line, wherein said restriction element restricts the flow area of the shear-thinned slurry and increases shear-thinning of the slurry.
