高い耐摩耗性を持つグラニュレータブレード及び該ブレードを鋭利にする方法

摘要

Granulator blades with a high wear resistance made of cold work tool steel, preferably with a high vanadium content and thermally treated after machining, at a temperature ranging from 500° C. to 700° C. The sharpening of the blades is effected by abrading the blades against the surface of the die plate, under suitable operating conditions.
