Patent attributes
The invention relates to a device to be used in connection with thickening and clarifying apparatuses for shear-thinning of solids containing material, such as slurry, which device contains one conduit for feeding material to be shear-thinnned and another conduit for discharging back the shear-thinned material between a thickening apparatus and the shear-thinning apparatus. The conduit (3,23) for feeding material to be shear-thinned and another conduit (4,24) for discharging back the shear-thinned material are positioned essentially concentrically to each other at least in the ends connected to the thickening apparatus (2,22).
