ZHENWEI Swing Screen is specifically engineered as a high-efficiency screening machine to meet the demands of manufacturers requiring large-scale output and high-precision particle separation. The most fundamental screening method involves visual inspection and manual sifting with both hands. The Swing Screen mechanically simulates this manual screening motion, embodying the most effective replication of human sieving principles to date (with screening accuracy, efficiency, and screen lifespan all reaching 5-10 times those of conventional rotary screens). It is universally compatible with fine and ultra-fine powders and granular materials, demonstrating exceptional performance particularly for challenging-to-process materials.
The basic rotational motion resembles manual sieving. The eccentricity is adjustable from 25 to 40 mm, and the rotational speed is regulated by a low-speed V-belt drive adjustable from 120 to 360 rpm.
The residence time of each product can be adjusted by modifying the radial and tangential angles of the trommel screen toward the drive axis.
Material on the screen surface forms a three-dimensional tumbling motion, combining horizontal and throwing movements. This allows the material to disperse evenly across the screen from the center to the periphery, propagating axially in a spiral pattern. Fine particles thereby complete the entire screening process.
Horizontal and vertical accelerations increase as particles move, enabling successful separation of particles close to the mesh size. Larger particles are transported to the discharge outlet, where an adjustable guide device controls the flow rate. This guide also serves as an additional factor governing material residence time.
This process is repeated between each screen layer.
Up to 5 times higher output per unit area; achieves precise separation up to 6 grades, with screening efficiency reaching 90%–99%.
Equipped with efficient self-cleaning systems (e.g., silicone rubber balls, ultrasonic cleaning) to prevent mesh clogging.
Closed-loop dust containment ensures safe operation.
Acceleration is 4.5 times lower than vibrating screens, extending screen component lifespan and reducing maintenance.
Noise level <75 dB.
Optimized dynamic balance minimizes dynamic load on the foundation.

The elastic ball self-cleaning system achieves screen mesh cleaning and anti-clogging through high-resilience bouncing balls installed beneath the screen mesh and above the support plate. These balls irregularly strike the mesh via secondary resonance, effectively removing blockages. Characterized by structural simplicity and outstanding performance, this solution is universally applicable to cleaning and anti-clogging tasks in most screening operations.
This cleaning mechanism employs rotating brushes positioned beneath the screen mesh to prevent clogging, specifically designed for spherical, crystalline, and brittle materials. The supporting arm of the rotary brush is driven by a gear reducer mounted on the base frame.
This system is specifically designed for ultra-fine material processing. It utilizes high-frequency vibrations generated by an ultrasonic generator, which are propagated to the screen mesh to prevent clogging. The technology not only ensures effective self-cleaning and anti-blockage performance but also significantly enhances production capacity. Additionally, its modular design allows on-demand customization of configurations to meet diverse screening process requirements.
This configuration features a two-stage screening process:
Top layer pre-screening: The material is initially separated into two fractions at the upper level. The fine fraction is collected by a blanking plate, while larger particles and unseparated fines are directed through a side channel to the center of the lower screening deck.
Secondary screening at lower layer: Employing screen apertures identical to the upper deck, this stage performs re-screening on the oversize material. This dual-layer reinforcement significantly enhances the classification accuracy of undersize material (product yield).
This screening configuration employs a dual-layer screening unit that can be equipped with one or two pre-screening decks featuring coarser screen apertures for preliminary removal of oversized particles. Through this design, the system achieves four-way material classification – capable of separating input materials into up to four distinct fractions in a single processing cycle.
This configuration is specifically engineered for materials containing high-percentage undersize fractions. The operational sequence features:
Upper deck precision screening: The top screen deck employs fine apertures for primary classification. Through particle interaction dynamics (where coarser particles actively fluidize the material bed), fine particles efficiently penetrate the screen openings and are discharged via a blanking plate.
Lower deck residual processing: Oversized materials and residual fines are routed through a lateral transfer channel to the lower screening deck for secondary separation.
This reverse-material-flow design achieves quadruple fractionation capability (up to four distinct product streams) in a single-pass operation.
This model of screening machine delivers the highest screening efficiency. Its configuration is equivalent to a double-layer screening setup with an additional third screening layer, all utilizing screen meshes of the same aperture size.
This configuration is suitable for operations requiring exceptional production output. It can be employed when simultaneously processing two high-capacity batches. This design is achieved through a distributor installed between the upper and lower screen meshes, which evenly divides the material flow. With this configuration, a single-layer screening machine can increase the output to approximately 180% of standard capacity. Anti-clogging mechanisms ensure operational efficiency.
