Circular vibrating screen (circular vibrating screen) is a new type of multi-layer and efficient vibrating screen. Circular vibrating screen adopts cylindrical eccentric shaft exciter and eccentric block to adjust amplitude. The material screening line is long and there are many screening specifications. It has the characteristics of reliable structure, strong vibration, high screening efficiency, low vibration and noise, durability, convenient maintenance and safe use. Circular vibrating screen is widely used in product classification in mining, building materials, transportation, energy, chemical industry and other industries. Circular vibrating screen is mainly composed of screen box, screen, vibrator, damping spring device, underframe and so on. The vibrator is installed on the side plate of the screen box, which drives the motor to rotate through the coupling or belt to generate centrifugal inertia force and force the screen box to vibrate. The screen is the main wearing part. According to the requirements of materials, products and users, high manganese steel woven screen, perforated screen and rubber screen can be used. There are single-layer and double-layer sieve plates, and all kinds of sieve plates can meet different requirements of screening effect. This series of circular vibrating screen is installed in seat type. By changing the position and height of the spring bracket, the inclination angle of the screen surface can be adjusted.
