ABSTRACT:
An interference knife apparatus is provided for use with an environmental material mixer. The mixer includes a tub housing at least one auger with blades mounted on the auger flight. The apparatus includes a post rotatably mounted on the outer sidewall of the mixer tub. The post can include one or more knives extending therefrom. Rotating the post moves the knives in and out of the mixer tub through access slots extending through the mixer's sidewall. The combination of the knives and the auger blades provides a “scissors-like” cutting action for cutting the environmental material during auger rotation.
