Tumbler Screening Machine
Maximum screening quality for fine and ultra-fine products
INTRODUCTION
The Tumbler Screening Machine is a high-precision screening system that uses three-dimensional elliptical movement to separate fine and ultra-fine particles from larger ones. It is an essential separation technology in mineral powder processing, chemical, pharmaceutical, food, and recycling industries where precise particle size classification is required.
Tumbler screening achieves up to 99% efficiency through its unique circular tumbling motion. The machines are designed for long service life and flexible angular velocity adjustment, making them suitable for a wide range of screening applications. The Tumbler Screening Machine requires controlled feed flow rate and specific particle size ranges for optimal separation performance.
Henan Innovative Industry manufactures Tumbler Screening Machines in 9 sizes ranging from 600 mm to 2600 mm diameter, covering both the TSM and tsi product lines. Our machines are commonly integrated into Raymond Mill, Ball Mill, and Roller Mill production lines for precise classification of ground mineral powders.

TSM / tsi PRODUCT LINE
The highly developed tumbler screening machines manufactured by Henan Innovative Industry have set the standard for fine and ultra-fine screening technologies across all types of dry bulk material. Modified and improved design features successfully applied to the TSM product line are now implemented to the entire tsi product line as well. Henan Innovative Industry currently offers the widest product range of tumbler screening machines available on the market worldwide, with 9 machine sizes ranging from 600 mm to 2600 mm in diameter.
STRUCTURE AND WORKING PRINCIPLE
The Tumbler Screening Machine is designed as an artificial imitation of low-frequency manual shaking motion. Its working principle is based on the synthesis of transient motion displacement combined with radial circular motion, forming a helical three-dimensional movement pattern. The eccentric drive unit generates a nonlinear motion that closely approximates manual sieving action, enabling precise and efficient particle separation.
This motion pattern makes the machine especially suitable for screening circular, cylindrical, flat, and irregular-shaped particles, including materials that are prone to blinding the mesh. When combined with appropriate mesh cleaning attachments, the Tumbler Screening Machine delivers highly accurate and consistent screening results.
UNIQUE TUMBLING MOTION
The Tumbler Screening Machine produces an exactly defined three-dimensional eccentric motion with both radial and tangential inclination components.
During operation, the radial inclination causes the product to move from the center of the screen toward the outer edge, while the tangential inclination generates circular motion across the screen surface. The combined effect of these two forces produces a helical motion pattern, resulting in a relatively long material retention time on the screen.
This extended contact time optimizes fraction separation efficiency while significantly reducing the amount of near-size particles remaining in the oversize fraction.

OPTIMIZED MULTIPLE DECK COMBINING SYSTEM FOR MAXIMUM PRODUCTIVITY
Maximizing the screening process performance and quality by combining optimized selected screen deck modules. This pays back quickly, particularly when handling high-quality bulk materials, since the proportion of oversize or undersize particles in the various fractions will seriously be reduced.
In addition to the examples shown here, Henan Innovative Industry provides a large scale of further machinery combinations for almost any given application.
Double screening machine DS
Screening into two fractions using two decks of identical mesh aperture achieves maximum recovery of the fine product.
Double screening machine with Pre-screening DS+1 (2)
One or two additional coarse screen decks placed on top of the DS machine increase the number of output fractions produced.
Double capacity screening machine DL
When screening into two fractions only, the DL machine configuration nearly doubles the output capacity compared to a single deck machine.
Two stage screening machine for reversed screening DSU
Fine material is removed first, while the remaining coarse material acts as a self-cleaning layer, improving the classification accuracy of the fine fraction.
CONTINUOUS MESH CLEANING GUARANTEES HIGHEST SCREENING QUALITY
Due to its circular body and unique drive system, the Tumbler Screening Machine is highly compatible with a range of mechanically driven rotating mesh cleaning devices. The screen is cleaned continuously during operation, ensuring consistently high screening quality and stable product flow throughout the process.
Bouncing balls
A universal mesh cleaning solution available in multiple variations, suitable for a wide range of granular products.
Ultrasonic
Particularly effective for fine mesh apertures ranging from 20 to 1000 μm.
Combined ultrasonic and balls
Delivers maximum product throughput through the screen with continuous and thorough mesh cleaning.
Air Flow
High-speed air jets from rotating arms positioned beneath the screen blow out particles caught in the mesh. Ideal for sticky or adhesive products.
Combined ultrasonic and air
Designed for products that are especially difficult to screen, such as fine plastic powders.
Conical rolling brushes
Rotating conical brushes positioned beneath the screen provide gentle, low-wear cleaning. Typically used for spherical products that tend to blind the mesh.
Combined air and brushes
An effective cleaning system for greasy or electrostatically charged products.
Passing/straining unit
Allows gentle dis-agglomeration of products such as instant coffee using rotating steel or plastic spatulas on top of the screen.
