Introduction
Particle separation, especially dielectric separation, is one of the key technologies in modern industrial production. It is mainly used in ore dressing and metallurgical equipment, chemical engineering and medicine, etc. In recent years, with the continuous rapid development of industrial production, particle dielectric separation technology has evolved into various forms. Among them, the dust particle Dielectric separation technology is the main direction of its research and development.
The dust particle dielectric separation technology mainly includes the following aspects: the dielectric separation technology of dust particles, the dielectric separation technology of granular particles, the dielectric separation technology of caking particles, etc. The dust particle dielectric separation technology is a common method used to separate mixtures composed of different particles, which is the most effective method.
Dielectric separation technology is a kind of advanced dust particle separation technology, which uses dielectric dissipation characteristics of particles to separate them. Under the action of electric field, charges of different particles are different, and their internal particles are also different, so they can be separated by using the magnitude of the dielectric constant.
In the dust particle Dielectric separation technology, dielectric properties such as dielectric constant, dielectric recovery, and dielectric absorption are adopted, and the particle mixture is separated in a precise way. Different dust particle separation technologies use different dielectric constants to achieve the precise separation of dust particles. Generally, the particle diameter of the dielectric separation technology range is between 0.1 to 50 microns, and the dust particle dielectric separation technology can effectively separate the particle size.
The advantages of particle dielectric separation are: it has high precision separation, can select different particles, and can be widely used in the fields of medicine, chemical, food, and even mineral processing. In addition, compared with other particles separation technology, dust particle dielectric separation does not need to use a lot of auxiliary materials, so it has less environmental pollution, but also more energy-saving and efficient.
The working process of dust particle dielectric separation mainly includes four steps: material feeding, particle size reduction, particle deformation, and particle separation. The whole working process is simple and can be divided into 3 stages: pre-treatment, separation, and post-treatment. In the pretreatment stage, material feeding is completed, particle size is reduced, and dielectric constants are adjusted. In the separation stage, material composition is adjusted and particles are separated. In the post-treatment stage, the particles are regrouped and the separated powder is collected for later use.
Conclusion
The dust particle dielectric separation technology has many advantages, such as high precision, wide application range and low environmental pollution. It has been widely used in industrial production, such as ore dressing and metallurgical equipment, chemical engineering and medicine. In addition, with the development of modern technology, the new dust particle dielectric separation technology is gradually forming a new industry. In the future, the dust particle dielectric separation technology will become more mature, and it will play a bigger role in the development of industrial production.
