Vibrating screen is the indispensable equipment used in the ore beneficiation process. Vibrating screen used in mining industry is mainly divided into two types: circular vibrating screen and linear vibrating screen. The vibratory screen is mainly made up of three parts: vibration exciter, working body and elastic component. 1. Vibration exciter can produce repeated exciting force to drive the working body. The common vibration exciters are inertia type, elastic rod connected type, electromagnetic type, hydraulic or pneumatic type etc. 2. Working body means the screening chamber. 3. Elastic components(spring) includes isolation spring, the main vibration spring and linkage spring, among which the isolation spring is used to support the vibrating body and reduce the dynamic load for the frame. The screening chamber of vibratory screen is welded with steel plate and fashioned iron or connected with high - strength bolt. The vibration exciter has two installation types based on the different working types: 1. in the upper part of the screening chamber. 2. in the bottom of the screening chamber. The vibration exciter, as the main part producing vibration, has a direct influence on the moving trail and screening effect on the working plate. The vibration trail of the materials is a complicated space curve whose projection on the horizontal plane is a circle and an oval on the vertical plane. The vibration screen cloth is the component which stands the biggest impact force. Materials are classified and dehydrated on it, so it is the most vulnerable part. In addition, the shape and distribution of the sieve pore has a direct influence on the screening effect. The vibration screen produces great vibration, noise and environmental pollution during production. In order to reduce the impact that vibration produces to the ground, the springs in the vibrating screen are distributed reasonably. Thus it also could improve productivity and prolong its service life. If you want to know more information about the screening machine, welcome to contact with Hongxing Machinery: sales@hxjq.com.
