Abstract: The present invention relates to a process for milling a cermet or cemented carbide powder. The process comprises circulating a slurry comprising powder(s) forming hard constituents, powder(s) forming binder phase and a grinding liquid through a grinding chamber. The grinding chamber comprises grinding elements and an agitator where the agitator is rotating around an essentially horizontal axis. The process according to the present invention provides a cermet or cemented carbide powder mixture at a significantly reduced milling time.
Abstract translation: 本发明涉及一种用于研磨金属陶瓷或硬质合金粉末的方法。 该方法包括使包含形成硬组分的粉末，形成粘结相的粉末和研磨液的粉末循环通过研磨室。 研磨室包括研磨元件和搅拌器，其中搅拌器围绕基本上水平的轴线旋转。 根据本发明的方法在显着降低的研磨时间下提供金属陶瓷或硬质合金粉末混合物。

Abstract: The present invention relates to a cemented carbide cutting tool insert/button for mining and construction comprising hard constituents in a binder phase of Co and/or Ni and at least one surface portion and an interior portion in which surface portion the grain size is smaller than in the interior portion. The surface portion with the fine grain size has a lower binder phase content than the interior portion.
