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.
