1. Introduction In modern industrial production, screening equipment plays an important role. Especially in the mining, building materials, chemical and other industries, the screening and classification of granular materials is directly related to product quality and production efficiency. As an efficient and accurate screening equipment, circular vibrating screen has been widely used in all walks of life. This paper will introduce the working principle of circular vibrating screen in detail, in order to provide useful reference for readers.
The basic composition of the 2. circular vibrating screen The circular vibrating screen is usually composed of a screen box, a vibrator, a suspension device, a bottom support and a screen. The sieve box is the main structure of the circular vibrating screen, which is circular or approximately circular, and the inside is equipped with a screen. The vibrator is the power source of the circular vibrating screen, which is connected with the screen box through the suspension device to drive the screen box to produce continuous vibration. The bottom support is responsible for supporting the entire screening equipment to ensure its stable operation.
The working principle of 3. circular vibrating screen The working principle of circular vibrating screen mainly depends on the exciting force generated by the vibrator. The vibrator is usually composed of a motor, an eccentric block and a transmission device. When the motor starts, the eccentric block is driven to rotate by the transmission device. The eccentric block generates centrifugal force during rotation, which causes the sieve box to vibrate periodically in the vertical direction. This vibration is transmitted to the granular material through the screen, so that the material is screened on the screen for three-dimensional motion trajectory.
Specifically, when the material enters the screen box from the feed port, it is subjected to the vibration force and begins to move along the screen. Due to the different physical properties such as size, shape and density of material particles, they will produce different motion trajectories under the action of vibration force. Smaller granular materials can pass through the screen smoothly and be discharged from under the screen; while larger granular materials will be intercepted by the screen, sliding or rolling along the screen surface, and finally discharged from the screen.
The working process of 4. circular vibrating screen The working process of circular vibrating screen can be divided into the following steps: 1. Material input: Put the granular materials that need to be screened into the screen box. According to the screening requirements, the size of the screen aperture and the tilt angle of the screen surface can be adjusted.
2. Start the vibrator: start the motor and drive the eccentric block to rotate through the transmission device to generate exciting force. The excitation force is transmitted to the screen box through the suspension device, so that the screen box produces continuous vibration.
3. Material screening: Under the action of vibration force, the material begins to move on the screen. Smaller particulate material is discharged through the screen, and larger particulate material is intercepted above the screen.
4. Classification and discharge: After screening, the materials are divided into different grades. The material under the sieve is discharged through the sieve, and the material on the sieve is discharged out of the sieve through the overflow port. According to the screening requirements, the screen aperture and the tilt angle of the screen surface can be adjusted to achieve different screening effects.
The characteristics and advantages of the 5. circular vibrating screen The circular vibrating screen has the following characteristics and advantages: 1. High screening efficiency: The process of particle size separation is completed through the three-dimensional motion trajectory, and the screening efficiency is much higher than that of the traditional two-dimensional vibrating screen.
2. High screening accuracy: the aperture of the screen is adjustable, which can be adjusted according to different screening requirements to achieve accurate classification.
3. Simple structure: The equipment has a compact structure and a small footprint, which is easy to install and maintain.
4. Wide range of application: suitable for screening and grading of various granular materials, widely used in mining, building materials, chemical and other industries.
6. circular vibrating screen as an efficient and accurate screening equipment, plays an important role in modern industrial production. By understanding its working principle and characteristics, we can better grasp its use methods, improve screening efficiency and product quality. With the continuous development of science and technology, circular vibrating screen will play a more important role in the future industrial production.
