  • Patent number: 5906435
    Abstract: A rotary drum mixer mixes product matter in a particulate form. A scoop section for the mixer has scoop blades which are radially enclosed by a peripheral wall which rotates with the drum. A stationary hood includes an outer face portion which covers the end wall of the scoop section and a peripheral portion which covers the peripheral wall of the scoop section, but neither the outer face portion nor the peripheral portion of the stationary hood contact product matter. The scoop blades are relatively flat and are angled into the direction of rotation. A back section is also included for the scoop blades. A seal assembly is positioned toward the inner diameter of the scoop blades and biases radially outward. The seal assembly may alternatively be positioned at the outer diameter of the scoop section, and/or the seal member may alternatively be biased radially outward. An inflatable bladder is used to radially bias the seal member against a hoop.
