Tungsten carbide grinding disc is one of the materials of vibration mill crushing disc, which is suitable for use in the case of samples without iron pollution and high hardness.
　　The outer body is wrapped with steel sleeve, not afraid of bumping, with O-ring sealing to prevent the powder from overflowing. Tungsten carbide grinding disc has high hardness and good abrasion resistance, but do not drop and knock, if you want to improve the life of the grinding disc should avoid tungsten carbide grinding disc in the vibration mill overrun.
　　The material of tungsten carbide grinding disc has only two components: WC and CO, the blank of tungsten carbide grinding disc is sintered, and then cut and processed to the required size, pure tungsten carbide powder can not be modeled, and a certain proportion of cobalt must be added in order to be sintered and molded, cobalt powder can be added to increase the physical strength of the grinding disc but the hardness is lowered, the higher the content of tungsten carbide powder the higher the hardness, but the strength is lowered and becomes brittle, so it is necessary to choose a very appropriate ratio to ensure that the grinding disk should have both high hardness, high wear resistance and high strength. After the finished product of tungsten carbide grinding disc characteristics: no iron elements, high hardness. x fluorescence spectrometer powder preparation requirements without iron element pollution, configuration of tungsten carbide grinding disc vibration type mill is widely used, tungsten carbide grinding disc because of high density (the same volume is about double the weight of steel), and the same specification grinding disc compared to the grinding grinding efficiency is higher, there are only two kinds of components of WC and CO, even if in the grinding and crushing process of itself has a trace of Even if there is a small amount of abrasion falling into the sample during the grinding process, it does not lead to iron contamination.
