Double-layer rotary vibrating screen is a commonly used screening equipment with double-layer screen structure and rotary vibration characteristics. This equipment is suitable for screening and grading of granular materials. The structure of the double-layer rotary vibrating screen includes upper and lower screens, which are usually driven by a vibration motor. The material is first placed on the upper screen, and as the equipment rotates and vibrates, the particles jump on the screen. Large particles will be blocked on the upper screen, while fine particles will enter the lower screen through the upper screen for further screening. This double-layer structure can improve the screening efficiency and accuracy, and is suitable for multi-level screening and grading of particles, which can meet the screening and grading needs of various granular materials.
The working principle of double-layer rotary vibrating screen is based on rotary vibration and double-layer screen structure. The material is evenly placed on the upper screen of the double-layer rotary vibrating screen. Subsequently, the vibration motor excites the vibration force to cause the entire screening machine to generate rotary vibration. This rotary vibration force causes the particles on the screening machine to jump. Under the action of vibration, large particles will be blocked on the upper screen, while fine particles will pass through the upper screen into the lower screen. This process realizes preliminary screening and classifies the particles according to size. After passing through the upper screen, the fine particles enter the lower screen for further screening. The lower screen usually has a finer aperture, which can screen and grade the particles more finely. Through the continuous screening process of the upper and lower screens, the double-layer rotary vibrating screen can achieve accurate screening and grading of particles. Large particles and fine particles are separated separately, so as to achieve the purpose of accurate screening. Users can adjust the vibration parameters and screen aperture as needed to obtain the best screening effect. By adjusting these parameters, it is possible to adapt to the screening needs of different granular materials and improve the screening efficiency and accuracy.
Scope of application of double-layer rotary vibrating screen
In the chemical production process, it is often necessary to screen and grade granular materials. Double-layer rotary vibrating screen can be used to remove impurities and extract pure materials. It is suitable for screening granular materials such as chemical raw materials and chemical products. In food production, powdered food raw materials such as flour, powdered sugar, and starch need to be screened to ensure the quality and purity of the product. Double-layer rotary vibrating screen can efficiently screen food raw materials, remove impurities, and improve the efficiency of food processing. In the production of building materials, it is often necessary to screen and grade granular materials such as sand and stone. Double-layer rotary vibrating screen can be used to screen sand and stone materials of different particle sizes to meet the needs of building material production. In the metallurgical production process, it is necessary to screen and classify granular materials such as metal powder and ore. Double-layer rotary vibrating screen can be used to accurately screen metallurgical raw materials and improve production efficiency. In plastic processing, it is often necessary to screen plastic particles, remove impurities, and improve the quality of plastic products. Double-layer rotary vibrating screen can effectively screen plastic particles and improve the production efficiency of plastic products.
Rotational vibration force: The rotational vibration force generated by the vibration motor causes the particles to jump on the screen, thereby realizing an efficient screening process. This rotational vibration force can help effectively separate particles of different sizes.
Flexible adjustment: Users can adjust the vibration parameters and screen aperture as needed to obtain the best screening effect. This flexibility enables the double-layer rotary vibrating screen to adapt to the screening needs of different granular materials and improve screening efficiency and accuracy.
Remove impurities: The double-layer rotary vibrating screen can help remove impurities from particles and improve the quality and purity of the product. Through the precise screening process, impurity particles can be effectively separated to improve the quality of the final product.
Automated double-layer rotary vibrating screen equipment can reduce the possibility of human operating errors, improve the stability and reliability of the production process, reduce production problems caused by human factors, and thus reduce production risks. The double-layer structure makes the screening process more orderly and reduces the blockage and confusion of particles during the screening process. The upper and lower layers of the screen cooperate with each other to improve the overall screening efficiency. Through the continuous screening of the upper and lower layers of the screen, a finer particle classification can be achieved and the screening accuracy can be improved. This is especially important for some industries with high requirements for particle size. The double-layer rotary vibrating screen is usually designed with three discharge ports to divert or classify according to different screening needs and particle characteristics. This allows particles of different sizes and masses to be effectively separated and collected to meet the particle requirements in the production process of different products.
