Products Description
| Product Name | Circular Tumbler Screener |
| Structure & Drive | Vertical round design, horizontal gear motor, eccentric shaft drive with rubber dampers. Stable, low-vibration operation; clearance required for swinging motion. |
| Main Applications | Dry powder classification and impurity removal. Optional cleaning systems (ultrasonic, brush, or bouncing balls) prevent fine powder blinding. Supports up to 5–6 size fractions per pass. Not for slurry/liquid filtration. |
| Material | Contact parts: Stainless steel. Frame/base: Carbon steel. |
| Typical Industries | Food, pharmaceutical, chemical, plastics, metallurgy – for continuous, dust-tight automated production lines. |
| Installation | Floor-mounted on level, hardened surface. Remove transport supports before use. No heavy foundation required; allow clearance for oscillation. |
| Core Advantages | Gentle action with minimal particle breakage; significantly higher throughput than conventional round vibrating screens at the same diameter; extended screen life; low operating noise; high classification accuracy; excellent anti-blinding performance. |
| Certifications | ROHS, REACH, ISO9001 |
Product Advantages
Product Advantages
- High Accuracy & Output – Compound motion (3D gyratory + planar swing) ensures even material distribution and full contact with screen apertures, achieving 95%–99% classification precision while delivering 5–10× higher throughput than conventional round screens at the same diameter.
- Gentle & Durable – Low-speed, manual-simulation action keeps breakage <1%, ideal for fragile materials. Acceleration is ~4.5× lower than vibratory screens, greatly extending screen mesh and component service life with reduced maintenance.
- Effective Anti-Blinding – Optional rubber balls, rotary brush, or ultrasonic cleaning systems effectively prevent clogging and agglomeration caused by ultra-fine, electrostatic, and sticky materials, ensuring stable performance across diverse applications.

Installation Instructions
Installation & Commissioning
Place the unit on a level floor and level the frame. Remove transport support rods from the base. Ensure adequate clearance for safe swinging motion. Install required screen mesh and cleaning accessories (rubber balls, rotary brush, or ultrasonic system). Seal the screen frame tightly to prevent powder leakage. Tighten all fasteners and run idle for 5–10 minutes to verify smooth oscillation with no abnormal noise or impact.
Production Operation
Start uniform and continuous feeding once the unit is running normally. Avoid sudden overloading or large instantaneous feed. Monitor output and adjust feed rate to maintain optimal screening accuracy and throughput.
Shutdown & Maintenance
Stop feeding and allow all material to discharge completely before turning off the machine. Regularly inspect screen mesh integrity and clean residual material from the chamber after each production run.
Application Scenarios & Precautions
Application Scenarios
- Food Industry: Starch, sugar powder, salt, milk powder, seasonings, xylitol, cereal powders, food additives
- Pharmaceutical Industry: Powder of herbal origin, pharmaceutical powder, protein powder, granulated medicinal forms, powder of medical raw materials
- Chemical Industry: Resin pellets, pigment powders, cosmetic raw materials, plastic pellets, chemical additives, ultra-fine dry powders
- Metallurgy & Mining: Metal powders, quartz sand, kaolin, graphite powder, non-metal mineral powders
- Other Industries: Feed pellets New energy materials Recycled powders Irregular particles Difficult to screen easy to blind materials
Precautions
- Remove transport supports before startup – Operating with supports installed will deform the frame and damage the drive system.
- Maintain uniform feeding – Avoid sudden overloading, which causes material buildup, reduced accuracy, and equipment clogging.
- Regular component inspection – Check screen mesh, rubber dampers, motor bolts, and cleaning system wear. Replace worn parts promptly to maintain performance.
- Use compatible materials – For corrosive or wet materials, choose 304 or 316L stainless steel. Carbon steel models will rust and suffer damage.
- Proper ultrasonic system use – Ensure reliable grounding and place in a dry, ventilated area. Do not operate without screen mesh installed to prevent no-load damage.
Performance Comparison
| Comparison Item | Circular Tumbler Screener | Round Vibrating Screen |
|---|---|---|
| Drive | Gear motor + eccentric shaft | Vibration motor with eccentric weights |
| Motion | Low-speed gyratory swing; long retention time | High-frequency 3D vibration; rapid material bounce |
| Efficiency | 90%–99%, excellent for fine/easy-blinding materials | 80%–90%, fine powders tend to bounce |
| Throughput | 5–10× higher at same diameter | Moderate, for small to medium flows |
| Breakage Rate | <1%, gentle for fragile/crystalline materials | 5%–15%, impact fractures particles |
| Screen Life | ~4.5× lower acceleration = significantly longer life | Rapid wear from continuous high-frequency impact |
| Anti-Blinding | Rubber balls, rotary brush, or ultrasonic options | Limited; fine powders cause frequent clogging |
| Noise | ≤75 dB, low vibration transmission | Higher noise, stresses foundation |
| Best For | Fine multi-grade separation, difficult powders, friable materials, high-output high-accuracy production | Coarse/medium sizing, budget-conscious, simple single-deck applications |
| Cost | Higher upfront, lower long-term cost | Lower upfront cost |
