Product Overview
The BY Series Circular Tumbler Screen is specially designed for applications requiring high capacity and high precision screening.
The equipment simulates the traditional manual sieving process through mechanical motion, creating a gentle and efficient screening method.
Compared with conventional circular vibrating screens, the Circular Tumbler Screen provides higher screening accuracy, improved efficiency, and longer screen service life. It is especially suitable for fine and ultra-fine powders, granules, and difficult-to-screen materials.
With its low-frequency and long-stroke movement design, the equipment reduces material breakage and screen wear, making it ideal for fine powder classification, multi-stage separation, and high-capacity screening applications.
Working Principle
The Circular Tumbler Screen adopts a crankshaft transmission system to generate rotary tumbling motion, simulating the manual screening process.
During operation, materials move across the screen surface through a three-dimensional tumbling motion. The material is evenly distributed from the center toward the outer edge and travels in a spiral pattern across the screen surface.
By adjusting the radial and tangential angles, the material movement trajectory and residence time can be optimized.
Materials enter continuously from the top inlet. Fine particles pass through the screen mesh, while oversized particles gradually move toward the discharge outlet. Each screening layer performs the same separation process to achieve accurate classification.
Key Features
Output per unit screening area can be significantly increased compared with conventional screening equipment.
Capable of multi-stage classification with screening efficiency up to 90%–99%.
Equipped with silicone rubber balls, ultrasonic cleaning systems, and other solutions to reduce screen blockage.
Low acceleration reduces material damage and extends screen service life.
Optimized balance design reduces dynamic load and operating noise, with noise levels below 75 dB.
Long service life of screening components and optional pneumatic devices allow quick screen replacement.
