Diamond powder and reducing segregation and aggregation

 Pelleting process in ancient Chinese medicine processing to get the application and development. Now widely used in the pharmaceutical industry, the preparation of powder metallurgy materials and alloys, metallurgy, ceramics and fertilizer industries. In recent years, the production of diamond tools in order to improve production efficiency ferrules and quality, so that it can automate production, and the development and application of the pelleting process.
Pelleting process in powder metallurgy and diamond tool industry was application and development, mainly due to it has the following advantages:
1. Improved flowability and improved. After granulation powder having a particle diameter of a large particle size than the original powder, each particle is surrounded by the number of particles may be exposed to reduced, so the adhesion, cohesion and mutual friction greatly reduced, thereby to improve and increase the particulate material mobility.
2. Diamond powder and reducing segregation and aggregation, more uniform distribution, improving the performance of products. Granulation process prior to powder, diamond mixed with a binder, and then add solvent mixing and granulation wetting again, every single diamond powder wrapped in quilts are then cold pressing and sintering, thus preventing polishing pads for granite  segregation and diamond powder aggregation, thereby increasing the sintering properties of products, uniformity and stability of the product.
3. Improve the accuracy of the product size and weight, since the mixed powder to improve flowability, the powder products more uniform loading of the cold, cold products, improve the accuracy of the geometric dimensions and weight. This repression shaped products, sandwiches, laser welding blade tips and the transition head better.
4. Reducing the loss of cold mold. Since the metal grinding wheel  powder fluidity, diamond powder parcels were distributed more evenly, so the cold mold loss reduction, die life by 50 or more.
5. Improve the efficiency of the process cold and economy, in order to achieve the cold automated production to create the conditions. As the improvement of powder flowability, die life, so that ordinary cold press automatic weighing more efficient, making the volume of the adoption of automatic cold press possible. A foreign company 32VPM volumetric cold press, according to the head design, the operating parameters entered into the computer, basically metal grinding wheel  do not care personnel, automatic production. Granulation and displacement using cold press, the head is reduced to suppress the time from 32S 10S; die life by a 12,000 increase to 25,000; cold reduced costs from $ 0.35 to $ 0.11.
6. Reduce body powder pollution hazards to workers. After pelleting process used to reduce fine particles easily broken, easy storage and transportation, so that dust emissions and pollution greatly reduced.
