I. Working Principle of Single-Deck Banana Screen

As materials enter the screening machine, the electric motor drives the exciter via pulleys, V-belts, and universal joints, generating vibratory force. This force is transmitted through the screen box and screen surface to the materials, causing them to follow a rolling, flipping, and sliding motion trajectory on the screen surface. Due to the banana-shaped design of the screen box, materials move along the curved screen surface while continuously subjected to vibratory force. During this process, larger particles quickly pass through the screen holes, while smaller particles remain on the screen surface. By selecting appropriate screen hole sizes, precise screening and classification of materials can be achieved. Furthermore, the banana screen boasts a self-cleaning function, preventing clogging of screen holes and reducing maintenance and cleaning efforts. The working principle of the single-deck banana screen enables efficient screening and classification of materials, enhancing production efficiency and product quality.

II. Differences between Single-Deck Banana Screen and Single-Deck Horizontal Vibrating Screen

1. Screen Box ShapeThe screen box of the single-deck banana screen resembles a banana, featuring an arc-shaped design, whereas the single-deck horizontal vibrating screen typically employs a rectangular or square-shaped screen box.
2. Material Movement PatternIn the single-deck banana screen, materials follow a rolling, flipping, and sliding motion trajectory on the screen surface. In contrast, materials in the single-deck horizontal vibrating screen primarily move back and forth horizontally due to vibratory force.
3. Screen Surface StructureThe screen surface of the single-deck banana screen is generally flat and of uniform thickness, accommodating the rolling and sliding motions of materials. Conversely, the screen surface of the single-deck horizontal screen is flat and horizontal.
4. Screening EffectThe unique shape of the banana screen and the rolling motion of materials contribute to better material separation and precise grading. The single-deck horizontal vibrating screen, on the other hand, relies primarily on vibratory force in the horizontal direction for screening.

There are notable differences between the single-deck banana screen and the single-deck horizontal vibrating screen in terms of screen box shape, material movement pattern, and screening effect. The banana screen achieves screening and grading through its specialized shape and rolling motion of materials, while the single-deck horizontal vibrating screen is suitable for horizontal screening of various granular materials.

III. Characteristics of Single-Deck Banana Screen

1. Self-Synchronizing Heavy-Duty Uniform-Thickness ScreenThe single-deck banana screen employs a self-synchronizing heavy-duty uniform-thickness screen box design, ensuring even screen surface thickness that can withstand significant material impact and vibratory force, providing high durability and stability.
2. Unique Screen Box ShapeThe banana-shaped screen box facilitates the rolling and sliding movements of materials on the screen surface, enhancing screening efficiency and separation capability.
3. Specialized Vibration Transmission SystemThe vibration transmission system of the single-deck banana screen transfers power from the electric motor to the exciter via pulleys, V-belts, and universal joints. The exciters are connected by intermediate transmission shafts, ensuring uniform distribution of vibratory force across the entire screen surface for stable vibration.
4. Extensive Application AreasBanana screens are widely used in industries such as coal classification, desliming, dehydration, and de-mediating. They are also employed in large-scale mining operations for screening and processing, efficiently screening and classifying materials to improve production efficiency and product quality.
5. High Capacity and Cost-EffectivenessCompared to traditional screens of similar specifications, the single-deck banana screen offers greater processing capacity, with a unit area capacity reaching 1.5 to 2 times that of traditional screens, enhancing production efficiency and economic benefits.
