Refiner for grinding of fibrous material
摘要:
The teeth of the stator and rotor of the refiner are each formed with a surface layer on the leading flanks which is harder than the end faces so as to maintain a sharp cutting edge. The hardness of the surface layer is at least 600 HB while the end face is of a hardness of from 280 to 320 HB.
