Abstract
An agitator assembly for use with industrial mixers that includes at least two rotating agitators, wherein each rotating agitator includes an agitator shaft, wherein the agitator shaft defines an axis of rotation extending from a first end of the agitator shaft to a second end of the agitator shaft; and first, second, and third sweep blades mounted on the agitator shaft, wherein the pitch angle of each sweep blade relative to the axis of rotation of the agitator shaft is between 30-60°; and wherein the rotating agitators rotate in opposite directions relative to one another when the assembly is in use.
Claims18
An agitator assembly, comprising:
- (a) at least two rotating agitators, wherein each rotating agitator includes:
- (i) an agitator shaft, wherein the agitator shaft defines an axis of rotation extending from a first end of the agitator shaft to a second end of the agitator shaft;
- and
- (ii) first, second, and third sweep blades mounted on the agitator shaft, wherein the pitch angle of each sweep blade relative to the axis of rotation of the agitator shaft is between 30-60°, and wherein the third sweep blade includes a first section that is oriented with a forward sweep directionality and a second section that is oriented with a reverse sweep directionality;
- and
- (b) wherein the rotating agitators are adapted to rotate in opposite directions relative to one another.
