Banana screen, named because of its unique shape like a banana, stands out in a large number of screening equipment, with its excellent performance and high efficiency screening capacity, has become a powerful assistant in the production of coal, sand and gravel aggregate, chemical raw materials and other fields.
Banana sieve screen surface is a multi-section different inclination design, the material can be quickly dispersed and reasonable residence time, easy to fully penetrate the screen, its unique structure also allows the material to be better stratified according to the particle size, which is conducive to the small particles through the screen mesh. Its large inclination angle starting section makes the material transport fast, not easy to pile up, and can make full use of the effective screening area. And the banana sieve adopts rubber spring vibration damping, smooth operation, reduce the impact on the equipment itself and the foundation, low failure rate, more stable equipment, longer life. Moreover, the screen box is made of high-strength steel, with optimised structure and solid key components, which can withstand greater vibration and impact. Banana screen has obvious advantages in dealing with viscous, wet, easy to agglomerate materials, and can adapt to a variety of particle size materials screening by adjusting the parameters.
一.Excellent performance in coal production
1.Coal classification: precise control of particle size
In the coal production process, coal classification is an extremely critical part, and coal with different particle sizes has different uses in the industrial field. When power coal is used for power generation, it is usually necessary to control the particle size within a certain range to ensure that the coal can be fully combusted in the boiler and improve power generation efficiency. In the metallurgical industry, the requirements for coal particle size are more stringent, such as coal for coking, and the proper particle size helps to ensure the quality and performance of coke.
With its unique design and working principle, banana screen shows excellent ability in coal classification. The banana screen’s multi-segment screen surface design with different inclination angles makes the movement trajectory of coal on the screen surface more reasonable. The large slope at the inlet end allows the coal to disperse quickly and achieve initial stratification, and as the material moves towards the outlet end, the slope gradually slows down, further screening out coal of different particle sizes.
2.Dewatering, desliming and demixing: improving coal quality
Coal often contains a certain amount of water, mud and media, and these impurities not only reduce the calorific value of coal and increase transport costs, but also may cause a series of problems during storage and use. Therefore, effective removal of water, soil and media from coal is crucial to improving coal quality.
Banana screen has excellent performance in dewatering and removing mud and media. In the dewatering process, when the coal enters the banana screen, the vibration of the screen surface causes relative motion between the coal particles, and the moisture is discharged through the screen holes under the effect of gravity and vibration. As the screen surface design of banana screen can ensure the uniform distribution of materials on the screen surface, and the vibration intensity and frequency can be adjusted according to the characteristics of coal, which makes the dewatering effect remarkable.
In terms of desliming, the banana screen can effectively separate the fine particles of impurities such as soil from the coal. The soil in coal will affect the combustion efficiency and quality of coal, through the screening of banana screen, these soil particles can quickly pass through the screen holes, and separated from the main body of coal.
For the use of heavy-media coal beneficiation process enterprises, the banana screen de-media function also plays an important role. In the process of heavy media coal separation, coal will be mixed with magnetic media, and the media needs to be separated from the coal after the completion of sorting. Through vibration and reasonable screen structure, banana screen can efficiently screen out the medium from the coal and realise the recycling of the medium. This not only reduces the production cost, but also reduces the pollution to the environment.
3.Production efficiency and economic benefits
Compared with traditional screening equipment, banana screen has significant productivity advantages in coal production. Due to the limitations of the structure and working principle of traditional screening equipment, the processing capacity is relatively small, and the screening efficiency is low. The banana screen’s large screening area and unique vibration mode make its processing capacity increase dramatically. In the same time, the banana screen can process more coal to meet the needs of large-scale production.
In terms of energy consumption, the banana screen also performs well. Its reasonable structural design and efficient vibration system enable the equipment to complete the screening task with low energy consumption during operation. In addition, banana screens have relatively low maintenance costs. Its high-strength structure and high-quality components make the service life of the equipment longer, reducing the number of repairs and the frequency of replacement.
二.The key role in the production of sand and gravel aggregates
1.Optimise aggregate grading
In construction projects, the grading of sand and gravel aggregates is directly related to the performance and quality of concrete. High-quality aggregate grading can make the concrete in the construction process has good compatibility, easy to pour and vibration, to ensure the compactness of concrete. After the concrete is hardened, reasonable aggregate grading can enhance its strength and durability, and improve the structural stability and service life of the building.
Banana sieve in the production of sand and gravel aggregate, its unique equal thickness screening technology can accurately screen sand and gravel particles with different particle sizes. By adjusting the inclination angle of the screen surface and vibration parameters, the output of aggregates at all levels can be precisely controlled according to the actual demand. In the sand and gravel aggregate production base of a large-scale construction project, after the introduction of banana screens, the gradation of aggregates produced is more uniform.
2.Adapt to mass production
With the continuous promotion of infrastructure construction, the demand for sand and gravel aggregates is increasing, and large sand and gravel aggregate production lines come into being. These production lines usually need to have high output and high efficiency to meet the large-scale market demand.
With its excellent performance, the banana screen can well adapt to the requirements of large-scale production. It has a large screening area and processing capacity, and is able to process a large amount of sand and gravel materials in a unit time.
In addition, the stability of the banana screen is also an important factor in its adaptation to large-scale production. Its structure is well-designed and made of high-strength materials, which can withstand long-time and high-intensity operation. In the actual production process, the failure rate of the banana screen is low, reducing the downtime caused by equipment failure and improving the overall operating efficiency of the production line. At the same time, its maintenance is relatively simple, further reducing the maintenance costs and downtime of the equipment, to ensure the continuity and stability of large-scale production .
3.Durability and cost control
In the sand and gravel aggregate production environment, the equipment needs to face the impact and friction of high hardness materials for a long time, and the working conditions are relatively harsh. Therefore, the durability of the equipment has become an important factor affecting production costs and production efficiency.
Banana screen in the design and manufacturing process to fully consider the durability of the problem. Its screen box is made of high-strength steel, and the side plates and beams are specially treated to have high strength and wear resistance. The screen surface is usually made of high-quality wear-resistant materials, such as polyurethane screen mesh, which not only has good screening performance, but also effectively resists the abrasion of sand and gravel and prolongs the service life of the screen mesh.
三.Innovative applications in the production of chemical raw materials
1.Fine screening to ensure quality
In the production process of chemical products, the particle size and purity of raw materials are extremely demanding. Take the pharmaceutical industry as an example, the active ingredients of drugs need precise particle size distribution to ensure the absorption effect and stability of drugs in the human body. Banana sieve through accurate screening technology, can be in accordance with the specific requirements of the chemical raw materials particle size for fine grading. In the production of paints, the particle size distribution of pigments and fillers has an important impact on the performance of paints. The banana sieve can accurately sieve the pigments and fillers to ensure that the paint has good levelling and covering power in the process of coating, and improve the quality and use of the paint.
2.Responding to special working conditions
The nature of chemical raw materials is complex and diverse, and some of the raw materials are corrosive, viscous and other characteristics, which poses a serious challenge to the screening equipment. Banana sieve in the design and manufacturing process to fully consider these special working conditions, through the use of special materials and structural design, to achieve stable operation in complex environments.
For the corrosive chemical raw materials, the screen surface of banana sieve and the parts contacting the materials are made of corrosion-resistant materials, such as stainless steel and engineering plastics. When dealing with chemical raw materials containing strong acids and alkalis, it can effectively resist the corrosion of acids and alkalis and extend the service life of the equipment.
For viscous chemical raw materials, banana sieve adopts special structural design, such as increasing the vibration frequency and amplitude of the screen surface, to prevent the accumulation of materials on the screen surface and clogging the screen holes.
3.Help chemical process upgrading
In modern chemical production, the banana screen is not running in isolation, but with other chemical equipment working closely together to promote the chemical production process to the direction of high efficiency and energy saving. In the chemical reaction process, the particle size and composition of raw materials need to be precisely controlled to ensure the adequacy and selectivity of the reaction. Banana sieve can accurately sieve the raw materials entering the reaction system, provide the appropriate particle size materials for the subsequent chemical reaction, improve the reaction efficiency and reduce the occurrence of side reactions.
With its unique equal-thickness screening technology, reasonable structural design and excellent performance advantages, banana screen plays an irreplaceable and important role in many production fields such as coal, sand and gravel aggregate, chemical raw materials and so on. With the continuous promotion of industrial modernisation and the continuous improvement of production efficiency and product quality requirements of various industries, the market demand for banana screens will continue to grow. I believe that in the continuous technical innovation and market demand, banana sieve will continue to improve and develop, for the efficient and stable operation of industrial production to contribute more power.
