The Use of a Baffled Rotating Drum Mixer in the Flocculation Dewatering of Florida Phosphatic Clay Wastes.
For Reference Only At Bureau Libraries :24 pages
The applicability of a rotating drum with an attached trommel as a flocculation dewatering device of Florida phosphatic clay wastes was studied. Several experiments were conducted to determine the important fabrication and operating parameters. Results from the experiments indicated that the dosage of polyethylene oxide required to form a satisfactory product cake could be reduced by using the rotary drum, which introduces less shear stress into the fluid than a constant stirred tank mixer.
