Abstract
This disclosure relates to an apparatus for a counter-rotating mechanical refiner configured to mitigate the problems of feeding variations, load variations, high energy consumption due to poor feeding efficiency, low pulp quality, and reduced throughput capacity by positioning a flinger proximate to a rotor gap side of a first rotor, wherein the first rotor further comprises an inlet extending through the first rotor, such that a portion of the operational flinger deflects feed material from the inlet into the refiner gap while rotating in the direction of the first rotor.
