Tumbler Screening Machine
The Tumbler Screening Machine (YBS Series) is a high-efficiency sieving solution engineered for precision separation of fine and ultra-fine powders. By simulating manual screening through a low-frequency gyratory motion, it combines radial displacement and spiral movement, enabling highly accurate particle classification with minimal material damage.
Unlike conventional vibrating screens, this machine generates a nonlinear three-dimensional motion via an adjustable eccentric drive (25–40 mm) and variable speed (120–360 rpm). This ensures uniform material dispersion across the screen surface, allowing particles to move in a spiral trajectory from center to edge for optimized screening performance.
Product Description
The Tumbler Screening Machine transforms motor-driven energy into a low-frequency, multi-dimensional mechanical motion, generating a combination of radial displacement and spiral tumbling movement. This motion is transmitted to the screen surface, enabling efficient screening and continuous self-cleaning, making the separation of fine and ultra-fine powders more precise and stable.
Based on traditional vibrating screens, this system adopts a low-speed, high-precision gyratory motion, which closely simulates manual sieving. The adjustable eccentric structure produces a nonlinear three-dimensional movement, ensuring materials are evenly distributed and screened across the entire mesh surface. This significantly improves screening accuracy while reducing mesh blockage.
It is especially suitable for applications requiring high-capacity, high-accuracy classification, particularly for materials that are easy to agglomerate, difficult to screen, or prone to clogging.

Working Principle
The tumbler screener operates through a mechanically simulated manual sieving motion. Material is evenly distributed from the center to the outer edge of the screen, forming a horizontal and vertical tumbling movement. Fine particles pass through the mesh efficiently, while oversized materials are guided to the discharge outlet via an adjustable flow control device.
This repeated multi-layer screening process ensures high precision, high throughput, and consistent product quality, especially for materials prone to clogging or agglomeration.
Typical Applications
Ideal for materials that are easy to block mesh and require high-precision classification, including:
- Chemicals and fine powders
- Food ingredients and spices
- Pharmaceutical powders
- Plastics and resins
- Minerals and metallurgy
- Fertilizers, feed, sugar, and salt
- Recycling and composite materials
This Tumbler Screening Machine is the optimal choice for industries demanding high capacity, accuracy, and reliability in powder separation.
