Abstract
An impeller for use in a mixing apparatus having a rotating shaft has at least one longitudinal member extending substantially radially from the shaft; and a plurality of individual impeller segments each having a bore therethrough. The segments are stacked together with the longitudinal member extending through said bores. The longitudinal member may be an at least partially threaded rod or may be a beam. A method of assembling an impeller for use in a mixing apparatus having a rotating shaft employs the steps of stacking a plurality of individual impeller segments onto a longitudinal member that extends substantially radially from the shaft; and fastening the stacked impeller segments onto the longitudinal member to retain the impeller segments on the longitudinal member.
