A vertical screw mixer consisting of an elongate container having a bottom, first end, a second end, and containing walls which extend between the first end and the second end. At least one opening whereby raw materials are directed into the container. A plurality of generally conical processing screws are positioned at spaced intervals between the first end and the second end. Each of the processing screws has an axis of rotation which is angularly offset from vertical by inclining the axis of rotation toward the second end of the container, such that a flow of material is promoted from the first end toward the second end. A processed material outlet is positioned adjacent the second end whereby processed material exits the container.
