It is a grinding container that grinds granular materials into powder by vibration. When working, put the grinding bowl into the slot of the sample pulverizer or vibration mill prototype. Through the eccentric vibration of the machine, the material can reach 60-300 mesh sample, and then be used for testing. It is the most widely used grinding method for preparing material samples in the laboratory. \u00a0\u00a0<\/p>\n\n\n\n

Grinding bowl is the main implement of sample grinding. Grinding bowl materials mainly include zirconia ceramics, carbon steel, high manganese steel, chromium steel, wear-resistant alloy, tungsten carbide, agate, Teflon, etc. The grinding bowl can be selected according to different materials. \u00a0<\/p>\n\n\n\n

The tungsten carbide grinding bowl is sintered from tungsten cobalt powder and then ground with diamond grinding wheel. Different from the cemented carbide cutter head material in machining, its material should not only have high hardness, high wear resistance, but also high impact resistance. To adapt to working conditions. Pure WC powder can’t be formed, so cobalt must be added for sintering. The higher the content of WC is, the higher the hardness of the grinding bowl is, but the strength decreases and becomes brittle. So choose the appropriate proportion. \u00a0 Although the grinding bowl of cemented carbide has high hardness and good wear resistance, it is not allowed to be smashed and knocked. Appropriate use methods can improve the service life of the grinding bowl. During charging, the samples should be evenly distributed in the middle of the solid core block, circular ring and bowl wall. In order to avoid unnecessary wear, please try to avoid the tungsten carbide grinding bowl rotating over the crusher. The WC grinding bowl is covered with steel to avoid bumping. The sealing ring is used to prevent the powder from escaping. Even if the grinding bowl itself is slightly worn and falls into the powder during the grinding process, it will not cause sample pollution. In order to avoid cross contamination among samples, it is recommended to use a tungsten carbide grinding bowl for each sample, chromium steel or manganese steel grinding bowl for coarse material crushing, and tungsten carbide grinding bowl for those requiring no iron pollution. \u00a0\u00a0\u00a0<\/p>\n\n\n\n

Tungsten carbide grinding bowl; X-ray fluorescence spectrometer is famous for its fast and high precision. In particular, X-ray fluorescence spectrometer for powder sample preparation is widely used in the field of material composition analysis. The powder fineness required by X-ray fluorescence spectrometer is 200-400 mesh (0.074 mm) to avoid the error caused by powder particle effect. \u00a0\u00a0 How to achieve the ideal grinding effect in the use of the machine, too long grinding time will cause the sample to stick and the grinding bowl temperature to rise significantly, too short time can not reach the grinding fineness, in order to get the best grinding effect, the user can adjust the grinding time according to the vibration frequency of the grinder. The pollution source on the surface of grinding bowl can not be ignored, so one or more waste samples (commonly known as pot brushing) should be produced as far as possible before formally crushing the sample. In order to be able to match with different types of sample making grinder, it can be customized \u0444 155\u3001 \u0444 183\u3001 \u0444 195 tungsten carbide grinding bowl with various dimensions.<\/p>\n\n\n\n
