A banana vibrating screen is a heavy-duty industrial linear vibrating screen named for its unique multi-slope, banana-shaped longitudinal profile. Designed on the equal-thickness screening principle, it features progressively decreasing angles from feed to discharge, delivering up to 2-3 times higher processing capacity than conventional screens for large-scale material classification and dewatering.
The working principle of a banana screen relies on progressive material acceleration and stratification across a multi-slope deck. It maximizes throughput by dynamically altering material speed from the feed point to the discharge edge.
The screen deck features multiple downward-sloping sections, typically transitioning from a steep angle (30°-45°) at the feed end to a shallow angle (0°-10°) at the discharge end. This progressive design ensures that material flows very rapidly through the steep feed section to form a thin material layer for instant fine particle removal, while slowing down at the discharge end for precise, high-efficiency separation of near-size particles.
Engineered for demanding industrial environments, our banana vibrating screen provides exceptional performance, reliability, and cost-efficiency compared to standard screening equipment.
Built with heavy-duty structural integrity, our banana vibrating screen incorporates robust mechanical components to ensure long-term stability under severe operational stress.

We offer flexible non-standard customization to seamlessly integrate our banana vibrating screens into your existing plant layout and operational workflows.
Founded in 2008, Dahan Machinery brings over 18 years of engineering expertise and hands-on manufacturing strength to the heavy-duty screening industry. We combine robust production capabilities with rigorous quality control, ensuring every banana vibrating screen is built to withstand extreme operational demands and meet international standards.
It is named after its unique longitudinal profile, which curves downward in multiple sections like a banana. This multi-slope design allows for progressive angle transitions that maximize throughput and screening efficiency.
Unlike traditional screens with a constant slope, a banana screen utilizes varying angles based on the equal-thickness screening principle. This allows it to handle 1.5 to 3 times higher material volumes while maintaining superior separation accuracy.
