Multi-Shaft Blades

The helical sweep blade is used in conjunction with scrapers to help move the product off the tank wall and combine it with material in the center of the tank. It also includes two spiral risers that extend from the bottom horizontal stabilizer to the top of the vertical up right on the opposing side of the blade. These risers allow the helical blade to move high viscosity material in the batch toward the high-speed blade. The helical sweep blade allows the operator to choose between a clockwise direction (pushing material up) and a counterclockwise direction (pushing material down).

This design has been standard in the industry for decades. While it will not provide the vertical movement in the batch that our helical design does, it will move the product off the wall to provide improved heat transfer and eliminate dead zones in the batch. Riser structures other than the triangular type normally require a stabilizer ring at (or near) the top of the blade.

The use of a single arm half helical blade in a multi-function, multi-shaft mixer results in significantly improved heat transfer compared to multiple riser, multiple helix mixers. The half-helix blade operates at lower peripheral speeds with easily replaceable scrapers that trail the vertical and horizontal portion of the blade.
