SINFONIA TECHNOLOGY CO., LTD.
Sinfonia Below Deck Drive Type Single-deck Screen Vibrating Equipment

Manufacturer: Sinfonia Technology co., LTD, Ltd.
Model: Below Deck Drive Type Single-deck Screen
Features
Rotary Vibrating Screens use powerful motors directly mounted on the trough for efficient screening of fine- to medium-sized materials. Smaller models operate at 1,450/1,710 vibrations/min with 2–4 mm amplitude, while larger models operate at 720/850 vibrations/min with 5–8 mm amplitude.
1. Lightweight and Robust Design
Direct-mounted vibrating motors eliminate the need for belts and additional drive components, ensuring a compact, durable structure.
2. Easy Vibration Adjustment
Motor pole settings and unbalanced weights allow easy adjustment of vibration frequency, amplitude, and screening capacity.
3. Stable Performance
The forced vibration system maintains consistent operation even when materials adhere to the screen.
4. Accurate Screening
One-deck and three-deck configurations provide precise, efficient screening for different materials and flow rates.
5. Easy Start and Stop
Push-button controls simplify operation, while automatic stopping prevents unwanted material movement.
