What Is a Banana Vibrating Screen?
A Banana Vibrating Screen, sometimes called a multi-slope vibrating screen, is a screening machine designed for high-capacity material classification. Its screen deck consists of several sections with different inclination angles, forming a banana-shaped profile. This design allows large volumes of material to be distributed quickly across the screen surface, making it widely used in mining, quarrying, coal, and aggregate processing plants.
Compared with conventional vibrating screens, a banana vibrating screen handles more material within the same footprint while maintaining good screening efficiency. It is particularly suitable for processing medium and fine particles, with plant capacities often increasing by 20% or more after upgrading from traditional screening equipment.
Working Principle
The Banana Vibrating Screen operates based on the equal-thickness screening principle. Its screen deck consists of multiple sections with progressively decreasing inclination angles, typically ranging from about 30°–34° at the feed end to around 10° at the discharge end. Driven by a vibration exciter, the screen generates continuous linear vibration, causing material to move rapidly across the steep feed section and spread evenly over the entire screen surface.
As the material travels along the screen deck, the decreasing slope gradually reduces its velocity, allowing particles to remain on the screen longer and improving stratification. Fine particles pass through the screen openings while oversized material is discharged from the end of the deck. This multi-slope design maintains a relatively uniform material layer throughout the screening process, resulting in higher throughput and better screening efficiency than conventional vibrating screens, especially in large-capacity mining and aggregate applications.
Specifications
Zhongyi offers Banana Vibrating Screens in a wide range of sizes and configurations to meet different processing capacities, particle sizes, and installation requirements. Screen length, width, deck quantity, vibration parameters, and screen media can be selected according to the characteristics of the material and plant layout. In addition to standard models, we provide customized designs for large-capacity mining, coal preparation, and aggregate screening applications. The following specifications are for reference, and custom solutions are available upon request.

|---|---|---|---|---|---|
| BS3673 | ≤300 | 970 | 8–12 | 2×22 | 160–750 |
| BD3673 | ≤300 | 970 | 8–12 | 2×30 | 190–800 |
| BS3685 | ≤300 | 970 | 8–12 | 2×22 | 200–800 |
| BD3685 | ≤300 | 970 | 8–12 | 2×30 | 240–1100 |
Applications
The equal thickness vibrating screen operates in coal processing, mining, and aggregate production lines. It is suitable for continuous high-capacity screening, especially under high fine content and unstable feed conditions. Also used in metal ore processing and sand & gravel production systems that require stable grading.
Is a Banana Vibrating Screen Better Than a Conventional Vibrating Screen?
For high-capacity mining and aggregate processing plants, screen selection directly affects production efficiency and operating costs. Compared with conventional circular and linear vibrating screens, the Banana Vibrating Screen uses a multi-slope deck design based on the equal-thickness screening principle, allowing more material to be processed within the same screening area. It is particularly suitable for large throughputs, fine particle classification, and applications where both capacity and screening efficiency are critical.

Project Cases
800 TPH Granite Aggregate Screening Plant Indonesia
A quarry in Indonesia needed to increase screening capacity without expanding the existing production line. The original screen struggled to handle high volumes of crushed granite, resulting in reduced efficiency and inconsistent product sizing.
Zhongyi supplied a 3-deck Banana Vibrating Screen for the aggregate classification stage. The multi slope screen design improved material distribution across the deck and maintained stable screening performance under continuous operation.
After installation, the plant achieved higher throughput, smoother material flow, and more consistent aggregate grading. The equipment continues to operate reliably in daily production with low maintenance requirements.
