Product Description K20 Tungsten Carbide Jar for Lab Ball Rolling Mill Parts with coverThis grinder grinds coarse materials into fine powder. During operation, the material bowl is placed in the slot of a sample preparation pulverizer or vibrating sample grinder. The machine uses eccentric vibration and operates for 3-5 minutes, reducing the material to 80-300 mesh, ready for direct testing. This is a widely used method for sample preparation in current laboratories.Recommended grade.The manufacturing process of a tungsten carbide bowl is relatively complex. The outer shell is made of ordinary 45-grade steel, and a tungsten carbide liner is inserted into the outer shell. Due to its high hardness, tungsten carbide achieves the highest level of hardness for the ground material.The tungsten carbide liner is made from sintered tungsten-cobalt powder, which is then ground using a diamond grinding wheel to form the finished product. Unlike carbide tool bits used in machining, this material must possess high hardness, high wear resistance, and high impact resistance to adapt to the working conditions.Tungsten carbide powder alone cannot be shaped; cobalt must be added to achieve sintering and forming. The higher the tungsten carbide content, the harder the bowl becomes, but the strength decreases, making it more brittle. Therefore, it's important to choose the right ratio. While the bowl is hard and wear-resistant, it shouldn't be dropped or knocked. Proper handling can extend its lifespan. When loading, try to evenly distribute the sample between the solid core, the circular ring, and the center of the bowl wall.

The tungsten carbide bowl is encased in a steel sleeve, making it impervious to knocks and impacts. A sealing ring prevents powder from escaping. Even if the bowl experiences minor wear during grinding and falls into the powder, it will not contaminate the sample. To avoid cross-contamination between samples, use a single tungsten carbide bowl for each sample. For coarse material grinding, use a chrome steel or manganese steel bowl. For samples requiring iron-free grinding, use a tungsten carbide bowl.How to achieve ideal grinding performance during machine operation?Too long a grinding time can cause the sample to become sticky and the bowl temperature to rise significantly, while too short a time will not yield a fine grinding result. To achieve optimal grinding results, users can adjust the grinding time based on the vibration frequency of the grinder. Contamination sources adhering to the bowl surface should also be considered. Before officially grinding samples, it is best to discard one or more waste samples.Package and Delivery Information (support customization)1.One plastic pipe pack one piece,10 pcs per group 2.Put goods enclosed with air bubble paper into box 3.Other package is accepted according to customer's requirement Other Products Show Who we are ?Zhuzhou Xingzhou Carbide Co., Ltd. located in Zhu zhou High-Tech Industrial Development Zone, it is one High Tech joint stock enterprise who specializes in the development, production and sales of tungsten carbide products.
