Resonance screen is a kind of high-efficiency screening equipment, which is widely used in mining, construction materials, chemical industry, metallurgy and other industries. It adopts the resonance principle and uses the vibration of the screen body to realize the screening and classification of materials. This article will introduce the working principle, advantages and applications of resonance screen in different fields.

1. Working principle

The working principle of resonance screen is based on the vibration resonance phenomenon. It consists of screen box, screen frame, vibrating motor and spring support system. When working, the vibrating motor transmits the vibrating force to the screen box through the exciter to make it vibrate. The screen frame installed on the screen box then sieves and classifies the material.

In the vibration process, the resonance screen makes the screen box reach the resonance state by adjusting the frequency and amplitude of the vibrating motor. When the material enters the screen frame, due to the vibration, the material is relatively displaced in the screen holes, and smaller particles will pass through the screen holes while larger particles are blocked. Through the setting of different sieve holes, the classification of materials with different particle sizes can be realized.

Mainly by the sieve box with screen inside, the lower body sieve box on the rate, the transmission device also has a certain forced vibration frequency, when the two frequencies are close to equal, so that the sieve works in a state close to resonance. Resonance sieve's (i.e. balance body), transmission device, resonance spring, plate spring, support spring and other components.

2, the advantages

High efficiency screening: The vibration frequency and amplitude of resonance screen are adjustable, which can provide higher screening efficiency and output. Its high frequency vibration and large amplitude can effectively improve the screening speed and separation accuracy.

Low energy consumption: resonance screen adopts resonance principle, which can effectively use vibration energy and reduce energy consumption. Compared with the traditional oscillating screen and vibrating screen, resonant screen can save more energy with the same screening effect.

Low noise: By optimizing the vibration system and vibration damping design, resonance screen reduces the vibration noise and creates a quieter working environment.

Less wearable parts of screen: resonant screen adopts spring support system, which reduces the impact and wear on the screen and prolongs the service life of the screen.

Automation control: The resonant screen can be integrated with the automation control system to realize remote monitoring and operation and improve the automation level of the production line.

3, application fields

Resonant screen is widely used in mining, construction materials, chemical industry, metallurgy and other fields. The following are the applications of resonance screen in different industries:

Mining: used for sieving, grading and removing impurities of ores, improving the grade and yield of ores.

Construction materials: used for sieving and grading of sand, limestone, coal and other materials, for preparing concrete, mortar and other construction materials.

Chemical: used for sieving and classifying of chemical materials, such as plastic granules, rubber powder, pigments, etc.

Metallurgy: used for screening, recycling and reuse of slag to improve the efficiency of metallurgical process and resource utilization.
