A ribbon blender consists of:
U-shaped horizontal trough
A shaft with inner and outer helical ribbons (like spirals)
The outer ribbon moves material in one direction, and the inner ribbon moves it in the opposite direction, creating a counter-current mixing flow.
This results in uniform and fast blending of materials.
