Rising energy costs and their increasing net effect on the cost of a mineral product requires that every aspect of processing-plant operations reduce consumed horsepower without sacrificing the grade of the product. This paper addresses two principles in the design and selection of axial-flow agitator propellers that contribute to significant reductions in required horsepower. The first of these involves the use of good design principles. The swirling wake generated by an agitator propeller induces losses in the pumping action. By designing an agitator of proper twist and shape one can minimize these losses. Depending upon the design chosen for comparison, these losses can be reduced by 30 to 50% without any sacrifice in pumping or without increasing the complexity of the design. The second aspect involves an appropriate selection of the agitator propeller diameter. The required horsepower can be significantly reduced by using a propeller of larger diameter while operating it at a lower revolutions per minute (RPM) with no sacrifice in the pumping. 3 references, 2 figures, 2 tables.
