The manufacturer of PDC for chain saw tells you that diamond powder is mainly divided into three categories: single crystal diamond powder, polycrystalline diamond powder and nano diamond powder. The manufacturer of PDC for chain saw tells you that the single crystal diamond powder is formed by grinding and forming synthetic diamond single crystal abrasive particles by a special process.

The manufacturer of PDC for chain saw tells you that polycrystalline diamond powder is made of graphite through a unique directional blasting method. The shock wave of the directional blasting of the high-speed explosive accelerates the flight of the metal flying piece, impacts the graphite piece, and converts the graphite into polycrystalline diamond. The PDC for chain saw manufacturer tells you that its structure is very similar to natural Caponado diamonds. The particles are composed of fine diamond particles combined through unsaturated bonds, and have good toughness. However, due to the limitation of synthesis conditions, there are few manufacturers and high product costs.
The manufacturer of PDC for chain saw tells you that diamond powder has high hardness and good wear resistance. It can be widely used for cutting, grinding, drilling, etc. It is an ideal raw material for grinding and polishing high hardness materials such as cemented carbide, ceramics, gems, and optical glass. Diamond powder products are tools and parts made of diamond powder.
The manufacturer of PDC for chain saw tells you that diamond powder is divided into three types: micron, sub-micron and nanometer in particle size. Compared with coarse-grained powder, its specific surface area and specific surface functional groups are significantly increased, so the force between particles in the production process is greatly increased. In addition, with the refinement of the particle size, the defects of the particles themselves are reduced, and the strength is bound to increase. It can be seen that the production process of diamond powder is very difficult. It is not only a process of particle refinement, but also changes in crystal structure and surface physical and chemical properties. Therefore, the production process of diamond powder is a multidisciplinary engineering technology problem involving machinery, powder engineering, mechanics, physical chemistry, modern instruments and testing technology.
The manufacturer of PDC for chain saw tells you that diamond powder is obtained by crushing and grading coarse-grained single crystal diamond. Crushing diamond with a ball mill is the most common method for producing diamond powder. The ball mill crushing method has been used in the production of diamond powder in my country for many years and has achieved satisfactory results. However, due to the shortcomings of low production efficiency, it has been replaced by wind mills. The air mill uses compressed air as the working medium, and the compressed air is sprayed into the crushing chamber at a high speed through a special supersonic nozzle. The manufacturer of PDC for chain saw tells you that air carries materials at high speed, and strong collisions, frictions and shears are generated between materials to achieve the purpose of crushing. The biggest advantage of the airflow crusher is that it is not limited by the mechanical linear velocity and can produce very high airflow speeds. In particular, the supersonic jet crusher can produce a speed several times the speed of sound, so it can generate huge kinetic energy, and it is easy to obtain micron and sub-micron ultra-fine powders. From the perspective of crushing principle, this model has broad application prospects in diamond powder production.
The manufacturer of PDC for chain saw tells you that particle size classification is a very important process in the production of diamond powder. It is related to the production efficiency and quality of diamond powder. At present, the most widely used diamond powder particle size classification method in my country is a combination of natural sedimentation and centrifugation.
