As shown in FIG. 1, the wiper blade 30 can be an integral part of the auger 16 or structurally connected thereto so that the wiping blade 30 rotates at the same speed as the auger 16.M.P. to provide excellent clay platelet orientation and separation to substantially increase the viscosity and decrease the fluid loss. As an example, the auger 16 and wiping blade 30 having 4 blade arms 34 are rotated at 1750 R. The particular speed of the wiping blade may be varied widely while achieving sufficient platelet alignment for unexpected improvement in viscosity and fluid loss characteristics.
