Tungsten carbide grinding disc manufacturers popularize the characteristics of tungsten carbide and tungsten carbide grinding discs

       Tungsten carbide grinding disc manufacturers popularize the characteristics of tungsten carbide and tungsten carbide grinding discs!



What is a tungsten carbide bowl? For those who see this term for the first time, this is confusing. The material bowl is also called a mortar. It is a grinding tool with a certain hardness that can grind the material into micropowder. It is made of tungsten carbide. The basin is one of many basins made of tungsten carbide and 45-gauge steel. Tungsten carbide has high hardness and is generally lined and embedded in a 45-gauge steel shell.



Tungsten carbide features:



1) The inner lining of the bowl made of tungsten carbide is made of tungsten carbide with high hardness, so it has high wear resistance and durability.



2) When the density is particularly high, it is made by a combination of No. 45 steel and tungsten carbide. The weight is larger than that of a single material, and the crushing and grinding efficiency is high.



3) The parts where the sample is uncontaminated in contact with the tungsten carbide bowl and the grinding material are made of tungsten carbide alloy. The mortar itself is slightly worn during grinding. Even if it falls into the powder, it will not cause sample contamination.



4) The bread outside the powder-free tungsten carbide bowl is covered with steel, which is not afraid of collision, and uses fillers to prevent powder loss.



The preparation of powders with high hardness and no iron pollution is required, especially the preparation of powders for x-fluorescence spectroscopic analysis devices, and the vibrating pulverizers of tungsten carbide grinding machines are widely used to prepare these powders.



Tungsten carbide grinding discs are roughly divided into three materials: manganese steel, chromium steel, and tungsten carbide. Users can choose according to their needs. Generally, chrome steel or manganese steel discs can be used for coarse material crushing, and there is no iron pollution. For samples requiring high hardness, carbonization is used. Tungsten disk.



Characteristics of tungsten carbide discs



The blank of the tungsten carbide grinding wheel is sintered and ground to the required size. The tungsten carbide powder cannot be formed separately. Cobalt can be added to sinter and form. The higher the tungsten carbide content, the higher the hardness of the grinding wheel, but the lower the strength, the more brittle, Therefore, to choose the appropriate ratio, it must have high hardness, high wear resistance, and firmness.



Due to the high hardness and high wear resistance of the tungsten carbide grinding disc, the density is high and the weight is about 2 times that of steel. Therefore, compared with the grinding disc of the same specification, only the grinding efficiency is high, only WC and Co are composed of two components. During grinding and pulverization, it wears a small amount of itself and falls into the powder, which will not cause iron contamination of the sample.



Tungsten carbide grinding wheel has high hardness and good wear resistance, but it is not allowed to drop or knock. Proper use can improve the service life of the grinding wheel. When putting in, please make the sample evenly distributed around the solid block and circular ring. In order to avoid the tungsten carbide grinding wheel idling in the pulverizer due to unnecessary wear.



If the grinding time is too long, the temperature of the grinding plate will rise, and the sample will become sticky. If the time is too short, the fineness of the grinding cannot be achieved. The user can adjust the grinding time according to the vibration frequency of the grinder and the required discharge particle size, because it is sticky and has high moisture content. The grinding effect cannot be obtained, so the high moisture content should be dried in advance, and the pollution source attached to the surface of the grinding wheel cannot be ignored.
