Abstract
Replacable refiner plates used for papermaking and refining of lignocellulosic and other natural and synthetic fibrous materials in the manufacture of paper, paperboard, and fiberboard products. The refiner plates include blade patterns and use corrosion resistant materials, as well as ceramic and ceramic composite materials. The blades and spacers overlap to define intercontacting surfaces with the blades and spacers metallurgically bonded throughout the intercontacting surfaces.
