Abstract
In one aspect, the invention is directed to a vertical feed mixer including a hopper for holding a composition to be mixed that contains strands of feed material. A vertically oriented mixing member is positioned in the hopper, wherein the mixing member includes a helical member and a shaft and is rotatable about a vertical axis in a direction to promote an upward flow of the composition to be mixed proximate the shaft. The helical member has an outer helical edge, a cutting blade at the outer helical edge and a cutout at the outer helical edge. The cutout and the cutting blade cooperate with each other to reduce mixing power consumption and improve mixing action.
