Recently, against the backdrop of the accelerated technological iteration of mining equipment, a mining banana screen (also known as a uniform thickness screen) that combines the advantages of high-efficiency screening and stable operation has become a "new powerful tool" for mining enterprises to enhance production efficiency through multiple technological innovations. It effectively addresses the industry pain points of traditional screening equipment, such as limited processing capacity and low screening rate of fine particles Inject new impetus into the high-quality development of the mining industry. ​
As a core equipment for material classification, dewatering and medium removal in mine production, the unique design of the mine banana screen has achieved a breakthrough in performance. Structurally speaking, the screen surface of this equipment adopts an inclined design of "steep entry and gentle exit". The inclination Angle at the feeding end is approximately 34°, while that at the discharging end drops to 10°. The side shape resembles a banana, which can guide the material to move forward and loosen rapidly from the feeding end, and then gradually reduce the flow rate as the inclination Angle of the screen surface decreases. Meanwhile, the application of the double-layer screen structure further optimizes the screening effect - the upper elliptical screen initially separates coarse materials, while the lower linear screen with an Angle precisely screens fine materials, allowing materials of different particle sizes to form differentiated movement trajectories and significantly reducing the phenomenon of material congestion. ​
In terms of the power and support system, the innovative design of the mining banana screen is equally eye-catching. The equipment adopts an irregular spring support structure, which can generate a greater vibration amplitude and screening force. Even when dealing with difficult-to-screen materials with high humidity and viscosity, it can maintain a stable screening efficiency. The side plates of the screen frame are connected by ring groove rivets, completely eliminating the problem of stress concentration. Combined with the crossbeam that has undergone stress relief treatment, it effectively extends the service life of the equipment. The helical gear transmission box-type vibrator with special bearings for vibration equipment has significantly enhanced the stability and noise reduction during operation, reducing the equipment maintenance costs and noise pollution in mining production. ​

Thanks to the core working principle of "equal thickness screening", the mining banana screen has demonstrated significant advantages in performance. The equipment generates centrifugal inertial force through the motor driving the vibrator, causing the screen box to form an elliptical trajectory vibration. When the material moves on the screen surface, the thickness of each material layer remains uniform, allowing fine particles to fully contact the screen mesh. The screening efficiency can reach over 95%. According to industry data, the processing capacity of the current mainstream models of mining banana screens covers 450 to 4,400 tons per hour. Among them, the processing capacity of large-sized equipment can reach up to 4,400 tons per hour, far exceeding that of traditional screening equipment, and can easily meet the large-scale production needs of large mines. ​
From the perspective of application scenarios, the mine banana screen has extremely strong adaptability. It can be used for both dry screening and wet screening requirements. It can not only complete the particle size classification of materials such as ores and coal, but also be applied in key operation links such as dewatering, medium removal and sludge removal. The person in charge of a large coal mining enterprise stated that after the introduction of the mine banana screen, the efficiency of raw coal screening in the coal mine has increased by 15%, the equipment failure rate has decreased by 20%, and the annual maintenance cost can be saved by over one million yuan. "The modular component design of the equipment is also very practical. The screen surface can be replaced with different materials such as mesh and plate according to the demand, and the installation and maintenance are very convenient. It has provided a strong guarantee for the stable operation of the production line. ​

As the demand for green and efficient production in the mining industry continues to rise, the technological upgrade of mine banana screens will also be continuously advanced. Industry experts point out that in the future, this equipment is expected to make further breakthroughs in intelligent transformation. By integrating Internet of Things and big data technologies, it can achieve real-time monitoring of equipment operation status, fault early warning and intelligent regulation, further reduce labor costs, and promote the transformation of the mine screening process towards "unmanned and intelligent". Provide more solid equipment support for the mining industry to achieve the goals of energy conservation, consumption reduction, quality improvement and efficiency enhancement. ​
