Tungsten carbide grinding disc is one of the materials of vibrating grinding disc, suitable for use without iron contamination and high hardness samples.
The outer body is covered with a steel sleeve, so it is not afraid of bumps, and the O-ring is used to prevent powder from spilling. Tungsten carbide grinding discs have high hardness and good wear resistance, but do not drop and beat them. If you want to increase the service life of the grinding discs, you should avoid idling tungsten carbide grinding discs on the vibrating mill.
The material of the tungsten carbide grinding disc has only two components: WC and CO. The blank of the tungsten carbide grinding disc is sintered and then cut to the required size. Simple tungsten carbide powder cannot be shaped, and a certain proportion of cobalt must be added to sinter For molding, the addition of cobalt powder can increase the physical strength of the grinding disc, but the hardness decreases. The higher the content of tungsten carbide powder, the higher the hardness, but the strength decreases and becomes brittle. Therefore, a very appropriate ratio must be selected to ensure that the grinding disc has high hardness. , High wear resistance, but also high strength. The characteristics of the finished tungsten carbide grinding disc: no iron element, high hardness. The powder preparation of X-ray fluorescence spectrometer requires no iron pollution. Vibration mills equipped with tungsten carbide grinding discs are widely used. Tungsten carbide grinding discs are dense (about twice the weight of steel with the same volume), and grinding discs of the same specification Compared with pulverization and grinding, the efficiency is higher. There are only two components of WC and CO. Even if there is a small amount of abrasion in the grinding and pulverization process, it will not cause iron pollution.
