Ribbon mixer

Ribbon mixers LDH series with single shaft and the Ribbon blenders with double shaft rotors are especially developed for mixing batches of free flowing and / or cohesive powders with different particle sizes and bulk densities.
The agitator rotates with minimum wall clearance in a U-shaped vessel. The mixing rotor consists of an inner and outer ribbon which effects a counter flow mass movement with random motion in radial and axial directions.
The typical rotation speed is depending on the product behavior in order to insure a quick overall mixing of the entire batch.

The mixing action in the ribbon blender is created by the following 3 factors:

The outer ribbon blender mixes the material from two sides to central part.

The inner ribbon blender mixes the material from central part to two sides.

Above movements can form a kind of convection during the mixture.
Main features of the ribbon mixers:

Mixing accuracy: Materials are mixed to the highest level of accuracy, even if some of the components are only present in minor quantities. The ribbon blender is suitable to prepare homogeneous blends with different components.

Mixer design: The Ribbon blender product line distinguishes itself by his compact and heavy duty design, making the ribbon blender suitable for the most challenging applications.

Fragile components: The mixing process is accomplished with a minimal energy input and without generation of heat and without damaging product structures.

Mixing efficiency: A homogeneous mixture can be achieved in a short period of time due to the rotor configuration. The mixers are able to mix batches in a size from 100 to 20.000 liters.

Fast and full discharge: The bottom outlet in combination with the small rotor wall clearances guarantees a fast and full discharge with a minimum of product remaining.
