Multi layer screening equipment banana vibrating screen Linear thick screen Large mine vibrating screen Coal banana screen
The banana type ore use vibrating screen used in mining is a self-synchronizing heavy equal-thickness screen, which is widely used in screening and processing of large amount of materials in mining. The processing capacity of banana type vibrating screen is larger, and its processing capacity per unit area is 1.5~2 times that of traditional classification screen
Working principle of banana type vibrating screen
Banana vibrating screen working principle :
The banana type vibrating screen has a slope at the feeding end, starting at 34 °, and then descending to the discharging end of about 10 ° at a certain number of angles. The screen surface adopts a broken line with different inclination angles, and the material layer thickness from the feeding end to the discharging end is unchanged. The ratio of material volume to flow rate on the screen surface of each section is stable, the material layer is high and uniform, and the screening efficiency is significantly improved, which is 1-2 times higher than the processing capacity of the vibrating screen with the same effective area. The banana type vibrating screen has extremely high screening efficiency for the high content of fine particles, especially when the material content in the material size is less than 1/2 of the classification particle size.
The banana screen has the following technical characteristics and advantages:
Simple and compact structure, high rigidity, high strength, balanced stress distribution, and large safety factor; The vibration parameters shall be set reasonably to avoid the natural frequencies at all levels of the screen body and reduce the resonance effect; Long service life, the service life of screen body is up to 10 years, and the service life of vibration exciter is more than 60000 hours; Light weight, low power consumption, high vibration intensity (9-12mm), high screening efficiency (>95%); The patented screen configuration of domestic brands is selected, with high screening efficiency and large material handling capacity; Low working noise, noise level lower than 75 dB, stable operation; The working system of the whole machine is S1, which ensures stable and continuous operation for 24 hours; The imported FFT professional frequency analyzer is used for frequency response and dynamic analysis; The variety is complete, which can fully meet the screening process requirements of different material characteristics and processing capacity; The screen machine is easy to operate and maintain, safe to use, cost-effective, sufficient spare parts, and timely and considerate service.
