This blending application probably requires two 50-hp mixers. The impellers need to be axial flow hydrofoils with wide blades, similar in performance to marine propellers. The impeller sizes depend on the operating speed of the mixers. Each 50-hp mixer needs a 58-inch diameter impeller if the mixer operates at 153 rpm, a 46-inch diameter impeller if the mixer operates at233 rpm. Because of variations in impeller design, the mixing equipment manufacturer should recommend the impeller size for a 50-hp mixer operating at their standard speed.
