Circular vibrating screen is a new type of vibrating screen with circular vibration, multi-layer number and high efficiency. The circular vibrating screen adopts cylindrical eccentric shaft exciter and eccentric block to adjust the amplitude. The material screen has long flow line and many screening specifications. It has the characteristics of reliable structure, strong exciting force, high screening efficiency, low vibration noise, durability, convenient maintenance and safe use. The vibrating screen is widely used in the product classification of mining, building materials, transportation, energy, chemical industry and other industries. Sports introduction Vibrating screen is divided into resonance screen and inertia vibrating screen according to whether the vibration frequency is close to or far away from the resonance frequency. Resonance screen once rose, received universal attention and developed rapidly; However, in production practice, the disadvantages of complex structure, difficult adjustment and many faults are exposed. The inertial vibrating screen is widely used because of its simple structure, reliable operation and easy maintenance. The inertial vibrating screen is driven by the inertial vibrator with eccentric block fixed in the middle to vibrate the screen box. Inertia vibrating screen can be divided into single shaft vibrating screen and double shaft vibrating screen according to the form of vibrator.
