In recent years, with the rapid development of China's economy and science and technology, screening technology has put forward higher requirements, the urgent need for screening equipment to efficient, large-scale development, the urgent need for more advanced performance, more reliable operation, higher screening efficiency, processing capacity, longer life multi-angle folding line screen surface new banana screen. As some domestic enterprises banana screen development time is short, low technology, manufacturing level is poor, no timely improvement to improve, difficult to finalize and promote, the product can not meet the higher requirements of use, so the design of new coal plant and old coal plant transformation mostly choose more excellent quality of imported equipment. banana screen in Germany, the United States and Australia and other developed countries after more than twenty years of research and development and practice, product technology international leading. In order to improve the technical level of China's equipment manufacturing industry, catch up with the advanced, banana screen technology innovation is imperative.

The new double-decker banana screen, mainly used for Coal classification, desliming, dehydration and demedia, is also suitable for screening and classification of other minerals. At present, some domestic enterprises banana screen development time is short, low technology content, manufacturing level is poor, no timely improvement to improve, difficult to finalize and promote, the product can not meet the higher use requirements. For the existing technology deficiencies, the new double-decker banana screen application of the principle of equal-thickness screening and linear vibration theory for optimal design, amplitude, frequency, excitation force and other vibration parameters according to the screening process requirements and scientific test results reasonable settings, just right, avoid the banana screen body at all levels of the inherent frequency, reduce the resonance of the screen body parts of the negative impact of force, improve the performance of the screen machine, extend the fatigue life of the screen machine. With a full range of screen models, it can fully meet the screening process requirements of different feed characteristics and different processing capacity.
