  • Mixing element having projections defining channels of varying width and depth for extrusion operations
    Patent number: 11472089
    Abstract: A mixing element for an extruder screw having a width extending in an x-direction of an x-y-z coordinate system, a length extending in a y-direction, and a thickness extending in a z-direction. The mixing element includes a base defining a passage extending along an axis in the y-direction for receiving the extruder screw. Projections extend radially outward from the base and define channels therebetween. The width and the depth of each channel vary along the length of the channel.
