Pneumatic vibrating screen is a kind of screening equipment widely used in industrial fields, which uses the principle of aerodynamics to screen, filter and classify materials through vibration. Pneumatic vibrating screen has the advantages of simple structure, convenient operation and high screening efficiency, so it has been widely used in chemical, food, pharmaceutical, metallurgical and other industries.
The working principle of the pneumatic vibrating screen is to use the compressed air generated by the air compressor to be transported to the exciter of the vibrating screen through the pipeline, so that the exciter produces high-frequency vibration. This high-frequency vibration is transmitted to the material through the screen, so that the material produces jumping, tumbling and sliding movements on the screen, so as to realize the screening and filtration of the material.
The screen of the pneumatic vibrating screen is its core component, and its material and pore size directly affect the screening effect. There are many options for the material of the screen, such as stainless steel, nylon, polyurethane, etc., which can be selected according to different material characteristics and screening requirements. At the same time, the pore size of the screen is also a key factor, and the appropriate pore size can ensure the effective screening and filtration of the material.
In practical application, the screening efficiency of pneumatic vibrating screen is affected by many factors. First of all, the nature of the material is the key factor affecting the screening efficiency. The particle size, humidity, density and other characteristics of the material will have an impact on the screening effect. Secondly, the vibration parameters of the vibrating screen are also an important factor affecting the screening efficiency. The selection of vibration frequency, amplitude and other parameters should be reasonably matched according to the characteristics of the material and the screening requirements. In addition, operation and maintenance have an impact on screening efficiency. Correct operation methods, timely maintenance and maintenance can ensure the long-term stable operation of the vibrating screen and improve the screening efficiency.
In order to improve the screening efficiency of the pneumatic vibrating screen, the following measures can be taken. First of all, the screen structure is optimized. The screening performance of the screen is improved by improving the material, pore size and arrangement of the screen. Second, adjust the vibration parameters. According to the characteristics of the material, select the appropriate vibration frequency and amplitude to improve the screening effect. In addition, anti-blocking measures can also be taken. For the materials that are easy to be blocked, an anti-blocking device can be set at the inlet of the vibrating screen to avoid the material blockage affecting the screening effect.
In practical applications, pneumatic vibrating screens have been widely used in various fields. In the chemical industry, pneumatic vibrating screens can be used for screening and filtration of catalysts, pigments, fillers and other materials. In the food industry, pneumatic vibrating screens can be used for screening and grading of flour, powdered sugar, milk powder and other materials. In the pharmaceutical industry, pneumatic vibrating screens can be used for the screening and filtration of raw materials, traditional Chinese medicine powders and other materials. In addition, in metallurgy, mining and other industries, pneumatic vibrating screens also play an important role.
In a word, as an efficient and practical screening equipment, pneumatic vibrating screen has been widely used in various fields. By continuously optimizing the screen structure, adjusting the vibration parameters and taking anti-blocking measures, the screening efficiency and service life can be improved. With the continuous progress of science and technology and the rapid development of industry, pneumatic vibrating screen will play an important role in more fields, bringing more convenience and benefits to people's production and life.
