The **Wonsen PRB Ribbon Mixer** comprises a **drive unit**, **U-shaped trough**, and **dual counter-rotating ribbon agitators**
(inner and outer helices). During operation:
**Material Convection Flow**
- The *outer ribbon* pushes material from **both ends toward the center** of the trough.
- The *inner ribbon* drives material from the **center toward both ends**.
- Creates intense **counter-current convective flow**.
**3D Homogenization**
- Material ascends along the ribbon edges and descends under **gravity**.
- Generates a **three-dimensional flow field** throughout the trough.
- Enables **rapid blending** with *short mixing cycles* and *low power consumption*.
**Discharge Mechanism**
- Post-mixing, material discharges via a **flush-mounted discharge gate valve** at the trough bottom.
- Valve operation: **Pneumatic** or **manual**.
- Adjustable discharge height enables **dust-free transfer** to downstream containers.
**Sealing & Loading**
- **Main shaft sealing**: Multi-layer PTFE packing in stuffing boxes at both ends (optional **lantern ring** for air purge).
- **Loading**: Top-fed via open trough or inlet ports.
- **Drain**: Central flush-bottom valve with cleaning connection.Generates a **three-dimensional flow field** throughout the trough.
- Enables **rapid blending** with *short mixing cycles* and *low power consumption*.
